I'll be down here for awhile now with gettin these 3 builds running :)

thanks for looking

[Lil Giants]

Another started project? :p

And a great choice of subjects too. I'll watch this one with great interest. :cool:

[Papy]

Great choice ! I really like those 3 axles mack dumpers and will follow your work with a lot of interest.

I am sure you already decided the cable shovel model you will build to load this beast.......... :D

thanks Papy I think I'll let someone's drag load it ;) till I get this and my other 2 projects working .

[kerst]

What scale is it?

[ihbuilder]

What scale is it?

1:14.5

[Papy]

......thanks Papy I think I'll let someone's drag load it ;) till I get this and my other 2 projects working .


You are probably right.....I got at least ten projects in process and the consequence is none of them is progressing fast ;)

[Southgate]

Cool; both the subject and project. The metalwork I see on this forum just blows me away! Dan

[9W Monighan]

HMM, One of the trucks we talked about.

What tires are those?

[Espeefan]

I have never seen one of these things before, but it looks huge! Definitely an interesting model. I'm interested to see this thing come together for you. The box looks really, really good. Nice job, Steve. It appears you scaled it down quite a bit, to match your tire selection. What scale are you building this Mack in?

[ihbuilder]

Steve , here's a link http://store.rc4wd.com/MIL-SPEC-ZXL-22-Tires_p_724.html I'm not sure just yet on using them :confused: I should have them look like the 1's tom made . I'm going to go through RC Machines . I think they have the right size and tread pattern . If all else fails I'll use these , they scale out right .

Nate , reply # 6 :rolleyes: :p 1: 14.5 I only ever got to see the small single axle 1's . I think that place had 1 of these , I just can't remember . Since the quarry changed owners , I believe they scraped them :( they made my f800 ( at the time ) look like a pick-up truck .

I'm hopping to have the frame together tonight . If I get my rear parts for next week end , I'll try to get my rears made .

[RCTech9]

Sweet Build!!!

[steamer]

Steve. The Macks looking real good. It's going to be a heavy weight for sure. Are you going to go with a standard drive train or gear motors on the axles. By the way have you got a steamer or are you using coal for heat.

[ihbuilder]

thanks every one

Lou , that guys a joke he puts pics of the whole pub. on the bay , anyone could just copy it . I down loaded it for nothing right off the i - net .

Papy , I thought it might be there too , who do you go by on there ? I haven' t been on in awhile . As I get further along I'll have to post this over there .

I got my rear parts yesterday , now just some time on my lathe :eek: hopefully next wknd.

IHSteve

[Papy]

Steve, you are right about this !
All this business on the bay around these old brochures or specs sheets is simply crazy: 4 pages leaflets "offered" for 20, 30, 50$ or even more :eek:.....and if you read the small lines all down the description, you finally see it's not an original document but a simple copy !!!! :mad::mad::mad:

Now, back to the real things : I like the way your model turns, and I am amazed how fast you work.....I started an LRSVW one year ago and I haven't done more than you by the time !!!!

Will you use real hydraulics for the hoist or will you manage a mechanical system ?

Do you have drawings or other info about the LRSVW?
I think that is an amazing truck.

Kerst

[Papy]

I got virtually no documents about the LRVSW.....photos and some infos from the net. Made drawings by myself ;)

I wouldn't want to go off-topic too much here, so PM me if you want the links to what I found

[ihbuilder]

Papy , you can put the links here , I'm actually interested in them to :) I like to keep as real as I can :D hydraulics ;)

[Papy]

OK. Here we go :)

some pictures + 2 pdf files with dimensions and various infos (http://www.trucksplanet.com/catalog/model.php?id=434)

3 artist drawings from original ads (http://www.hankstruckpictures.com/szalus.htm)

winter 2007 issue of the bulldog magazine (http://www.macktrucks.com.au/Content/Attachment/News/Bulldog_v81.pdf) : read article from page 18 (you can probably goooogle the american version with imperial measurements....)

2 pictures (http://public.fotki.com/eex-joe/old-mack-brochures-/)

an article with some pictures (http://www.bigmacktrucks.com/index.php?autocom=gallery&req=si&img=2539)

1/50 model (http://www.constructionscalemodels.com/productList.aspx?description=lrsw)

From all this, I could make my own scale drawings. They are probably not 100% accurate, but I think I captured the look of the truck not so bad. I may try to upload them here, but:
- they were only intended to give me some indications for the building, so they are not "industrial" drawings
- I still have to figure out how to convert them to a format that can be seen by everybody (made them on AutoCAD)
- all dimensions are in millimeters and the scale is not 1/14.5 but 1/14.285714.....:p:p:p


Ooops ! I forgot 2 things :
- thank you for the invitation in your topic
- good choice for the hydraulics ;) will you use existing products or make them yourself ?

[kerst]

Thanks a lot!

[ihbuilder]

Papy , no problem :) in your links is the pic for the M series I was looking for ( frame and suspension :D ) I got the right size chunk of aluminum to mill for the frame piece :D I'll be making the cylinders the pump , I'll see how the UMS pump works . If it does not have the nards , then I'll put mine in it .

IHSteve

He, he !!!! I like the rugged I-shape frame and the walking beam type rear suspension :D

I have previously made drawings of the M45SX. Basically the same shape as the M75....if this helps, you can have them.

For the hydraulics, at 1250 psi the pressure of the original Heil hoist system is very low compared to modern systems. In model form, this pressure could probably be reached by one of these fuel pumps for RC cars, just using a stronger motor or even with a windshield washer pump.

By the way, the pump of the Wedico #294 kit (http://www.gardentrucking.com/products.tpl?command=search&db=cma/parts.db&action=search&cart=129921966830202128&eqCATEGORYdatarq=Hydraulics&eqMAJORCATEGORYdatarq=products&Titlesumm=t&Titlesort=1&max=10&startAt=11) is nearly exactly set at the correct pressure (6 bars = 85 psi --> 85 psi x 14.5 = 1232 psi).

Another possibility : topsflo pumps (http://www.topstec.com/Aspde__EnProductShow.asp?ID=93). Not tested though.........

[modelman]

Ihbuilder-I've been watching this build with great interest. That must be a big truck to hold that shovel full of coal.

[Bigrigger]

Looking good Steve! Keep it coming! Awesome Mack!:D

[Dreamweaver]

I think truth be known, the reason Steve is building this truck is so he has something to haul off the shavings from making all those rims.

[ihbuilder]

NO , thats what scrappy is for :p but I'll need to build some more and get some guys w/their tractors in the shop :D . this it to make unloading coal fun :D . My wife just said , " you didn't make it big enough " so when I build her 1 , look out :eek::p:D:D this is a 75 ton truck , she going to get a 300 ton truck :eek::p

Doodlebug, Thanks for the link to the CAD programs. I have been looking for one to use with my CNC mill. Program looks easy to use plus has excellent instructions.

Steve very nice loking build.

Hey Lynn, I've had good luck with this program opening .dwg files. Case in point you have to have it for the Western Star body builder download's (zipped).
Yer welcome, Neil#2 aka doodlebug

[tracksntreadslou]

Coming along very nicely ..Im pretty amazed at how fast you build these things steve..and with all the other work you have lined up its good see your making time to do your own stuff.
Hey steve what are your plans for diffs for this brute?..Looking threw my spare parts box i came accross some tamiya Mammoth/juggernaut diffs that look very hefty..they are top drive and with a little mods i think you could make one with a rear output as well..

[ihbuilder]

Lou , I'm actually going to make my own drives using HPI savage internals . I got the spools and pinions and I just ordered my bearings . I got to the point ( finally ) to work on others parts to a certain time then I work on my stuff . I just need another lathe now :( I spend a lot of time resetting or I put my lathe work on hold till I get a break between set ups .

[9W Monighan]

Get more chucks for the lathe and a Aloris toolpost. Then you can switch out a chuck without disturbing a setup and leave a special tool in a holder.

Kerst , I'm Making mostly Wheels right now and air cleaners and fuel tanks . I have pics in IHB in the vender section .

Steve , I have a tool post not the aloris brand I begged for that a long time ago when I was in my dads shop . as for chucks I would have a bunch but , I can't get the right thread for the adapter plate . I need to get 1 made for my 3 jaw

I was just ready to make my back hangers for the front springs , I need another .25 " end mill :mad: I don't think I'm getting HSS any more :( Well I did get some more done :) front springs and center webbing for the rear . I'm hopping to start on axle housing this coming wknd ,wife has plans on sat :(

IHSteve

[ihbuilder]

No I did not stop :p I got some nice end mills yesterday and spent last night and tonight making the front axle and rear spring hangers for the front .
I also got some aluminum flux for welding aluminum with the torch and it works real well . So looks like I'll be making the cab in aluminum ;) works just like brazing
I hope you can see these :confused:

That trans should motivate it well. That is one beefy machine!:eek:

[tc1cat]

Boy you learn fast! Great looking work! I stopped getting HS tooling quite awhile ago. Carbide is more expensive but lasts much longer, so it's a fair trade off. My shop time has dropped to about 0 after knee surgery. And to top it all off, I think my Sherline mill is in need of new gibs. Really not bad after 20+ years of use and a new bed.

OK, you will say I'm a "rivets counter", but the M75 had a tubular front axle ! So I propose you to send this one to me (will fit perfectly for the LRVSW) and make a new one with the correct design :D:D:D

[ihbuilder]

I know ,Papy :p I sometimes throw my own twist to things :rolleyes: the body is off a lil to :confused: I think I got the rear taper to long . I was going to do the tubular axle but I just felt like milling an I beam front . I may do another but as a tractor but thats a lil while yet . I think I got enough going for now :eek:

IHSteve

With hubs drying waiting to be put together to finnish this order finally :eek: I stole some time on the lathe :D and turned out 1 rear housing :)

Rob , I'll be using 3mm bolts which I still have to mill bolt areas on the flang once they're bolted together then chuck them back up perpendicular and bore for the pinions that'll be a fun setup :eek:

[Espeefan]

Awesome work, Steve. I am looking forward to seeing the updates, as they come, which is usually what I reply to all of your posts! You have a lot great project builds going at once. I can't believe you get as much done as you do. If I even tried to do what you do, it would take me a lifetime, probably.

Steve. Looking forward to pictures of that setup.
Rob

[sparkycuda]

This truck is really looking really good. I understand you are running twin motors with different-from-stock pinions and driven gear going into the transmission? Would appreciate some detail on what gears you are running and did you have to build the two-motor bracket.

Thanks!

Ken

[ihbuilder]

Ken It's an E-max tranny they come with 2 motor set up . The best guy to tell you about what I have would be Travis . I'm kinda trusting his jugement on the motor trans setup . If it works and has what I need for the pan , I'll be putting these in them too . I like the 2 speed idea . :)


thanks Troy ;)
Rob the set up will take longer to true it up then to cut . If I get the CNC mill working , it'll be easier on that then the lathe , I'm thinking . If not then in the 4 jaw .

Steve

[Heavy Metal]

Just awesome work on this Steve. Looking great!!

What specific flux are you using on the alum?...was thinking about giving this a try...but not a welder. How hot we talking...do I need real tanks and torch or something that could be done lower heat like w/ little coleman propane torch?

Joe

[ihbuilder]

thanks Joe B. , On the thin sheet a little propane will work but .125 and up gota use some heat . I got alumna flux at the hardware store made by forney and thought I give it a shot . you just got to watch the heat on the sheet , you'll warp it just like steal . It's hard for me to explain how , since I do it by feel :o . I only messed with it on some scrap , so we'll see how I do on the truck :confused:

Steve

[mazdaparts]

The Emaxx tranny is a beautiful thing. I use them for most of my trucks. Are you gonna keep the 2 speed or make it a single speed? There used to be a conversion kit that almost cut it in half and basically locked it in 1 gear. I think you can still get an aluminum tranny case for it as well. Make sure you don't over tighten the tranny mounting screws, they strip out easily.

[russisloud]

really starting to look like a dump truck now. its coming together great

[SmallHaul]

Good progress Steve. That is cool that you are making the axles!

[tc1cat]

Steve, Do you ever sleep??:rolleyes::rolleyes: Seems like you are always making something besides all of the wheels you make. Old big machines are not all that bad. Most are built heavier than the new stuff which means you can do more before they break!! Keep up all of the good work!

Lynn , I put most of that lil puppy together sunday night after east mini truck meet .I basically used the merc running gear I had . I do not have much to do with it yet just make the body dump . As for the lathe , how many lil lathes take .25" off of 6061 t6 in a path ? my dad got a lil 7x10 clarke and said thats all he needed and didn't have a dino taking up space in the shop now he has me doing his stuff :eek:

I got more done will post tonight :)

Great Job

P.S. I see a set of fenders in the back ground, I know someone that makes the proper mounts for them...:D

[9W Monighan]

Hope everything lines up ok in there Steve. That's definitely a strong setup if the pinion holds up. Do you have a link to the gears you are using?

[ihbuilder]

Steve , here's the pinion http://store.rc4wd.com/HPI-Racing-Bevel-Gear-13-Tooth-Savage-21-_p_1377.html

the rest I got off ebay same as what I have in the pan only I made the axle housing for the truck . Here's a listing http://cgi.ebay.com/HPI-Savage-X-25-Complete-Alloy-Differential-Assembly-/200585583721?pt=Radio_Control_Parts_Accessories&hash=item2eb3d51c69 Oh yes everything lines up :D thank gawd :eek: I didn't want to do it all over :eek: I still have to make the axle shafts . I may take the cups off the diffs and run the axle shaft right in . This what the cups look like http://cgi.ebay.com/HPI-86864-Differential-Shaft-14x34mm-Black-Savage-X-25-/350295126788?pt=Radio_Control_Parts_Accessories&hash=item518f377304#ht_4874wt_872 they go into the spool and you slide a pin through the end then the bevel gear goes over top .

mike , your looking at the rear axle components . axle housing done on the lathe

thanks Clyde :)

[td9clyde]

i really need to get a four jaw chuck ........but then again i gotta get my barn made into a shop first hope to be gettin it all done this summer

[Heavy Metal]

Beautiful Steve.

[Jared]

Looks good! I've been following along partly because I don't know much about Mack off-highway trucks and because it's so different.

I was curious how the tandem axles would be driven. Not trying to be nit-picky, but is this the way the axles will be oriented when they go in the truck? If I'm looking at them the way I think I am they may wind up with one spinning forward and the other backwards unless one is flipped upside down. The front axle ring gear will reverse the rotation of the jackshaft. You may already have that taken into account but I would hate to see it happen. Years ago, a couple guys from my area built a monster truck from surplus army truck parts and when they were ready to take it for a drive the axles turned opposite! I'm not sure if they ever got it driveable.

http://i830.photobucket.com/albums/zz230/ihbuilder/PIC_1037.jpg

[ihbuilder]

Thanks Guys :)

Jared , yes , when put together the rear rear will be flipped . I guess I could have went into more detail and made a power divider like the real trucks .

IHSteve

[tc1cat]

WOW!!! your workmanship just seems to be never ending. :):) Can't wait to see it under power.

keep up the good work!

OH , " neccessity is the mother of invention " is on my shop door :p

just looked at another lathe today :confused: I wasn't going to :rolleyes: but curiosity never really killed the cat , the handle fit perfectly :D now the fun part trying to get it :(

[ihbuilder]

I did a little yesterday mounted the front axle made some hinges for the body :confused: may mill an authentic looking assembly :confused: and I've been dragging my feet on making the rear hangers in hopes of using the big mill :( but got tiered of waiting :confused:

Looking good there, Steve. You'll have it finished in no time:rolleyes::rolleyes:

well my butt is draggin today :eek: finished up about 4 AM 8 hrs of cutting :eek: but then I kept my feed down I hate breaking EM's mid way through :mad: I tried to flip it over and do the inside this morning but the stock is a lil out of square + being tired I was running the wrong program :o :rolleyes: oh well enough B.S. pics

Steve. You knocked that one, right out of the park, and there must have been quite a pile of chips on the floor. The frame on this truck looks like it will be rock solid and heavy duty. :D
Rob

[ihbuilder]

thanks Rob :) I got the back milled out just off the mill 30 min ago :eek: ( I'm gona get some sleep :D ) everything went well till the drill cycle :( for some azz reason my holes are out .125" :( I should have waited and bored the 2 together manually :confused:

Hmm, Did you forget to take .100'' off from the edgefinder?

Any pictures of your set up on the machine?

[ihbuilder]

Hmm, Did you forget to take .100'' off from the edgefinder?

Any pictures of your set up on the machine?

yes I remembered that other wise the backside pocketing would be off . It may be that when using the cam I clicked on the circle edge and not center :confused: I'm not sure you can see it in this vid http://www.youtube.com/watch?v=XLyOWczx1DQ
if not I'll take a pic when I do the other side or a trailer frame I'm going to set up . It's basically a fence that I can bolt the stock to .This trailer frame set might take a few days + igot to get more plate for the othe side :(

[9W Monighan]

It may be that when using the cam I clicked on the circle edge and not center :confused:

For drilling, I draw points to generate the code .

[tc1cat]

Looking good!! And everyone thinks that running a CNC mill or lathe is just push the go button and everything comes out OK :rolleyes::rolleyes: Slowing down the feedrate is not that bad of a thing to do. Recommended feeds and speeds are not all what they are cracked up to be!!!

[ihbuilder]

thanks Lynn , tell me about it :rolleyes:I tried to tell my wife that :eek: now she gets it :p , I just never spent so much time at the puter then the machine :eek: I cut the recomended feed down by 30% seems to work well I just worked up the next op for those trailer frames with the other frame in it 12 hrs :eek: I'm thinking I need to find a water jet guy for the basic profiles :confused:

[ihbuilder]

"Any pictures of your set up on the machine?"

Steve , as I promised :) also this time I decided to use a bigger EM and crank the feed up also the spindle much better time

http://i830.photobucket.com/albums/zz230/ihbuilder/PIC_1361.jpg

now these get chucked up in the lathe to turn the ends where the arch stops . there's a pic of it I just got to figure how to get it on here :confused:

thanks for looking :)

[doodlebug]

Hey Steve, are you going to chuck the walking beam's in your 4 jaw chuck? or use a dead center and lathe dog? Center drilling for the tail stock(live center) look's like fun.
Later, Neil#2 aka doodlebug.

[ihbuilder]

Neil , yep alredy done ;) did them last night while I had the mill working on a jig plate for wheels :D . the old hendy need soom work , the handle where getting rusty :eek:

Speed up them wheels production! The rails look awesome, definitely a match to 1:1. :eek:

[Dreamweaver]

This thing is coming along great Steve.. It's a monster..

I have some idea of it's size from the picture with the alcohol bottle next to it but how about a picture of it next to your Green corn binder...

~Mike~

[ihbuilder]

heck Matt I'm running double shifts now , I figured since I had room on the piece of plate for the trailer I cut soom parts for this :cool: the mill basically running non stop :eek:

Mike I'll try , you might have to wait till january when I get the trucks out for cabin fever expo .

[D8R]

Very nice frame sides, are the milled on both sides or only out side? What is the time (approx) for milling one side?

Dan

[ihbuilder]

thanks Dan , both sides . The initial op (1 side ) was 8 hrs on the flip over just shy of 3 hrs to mill between the flanges . I have about 24 hrs with a set of trailer frames and the 2nd mack frame and the walking beams . All out of 1 piece of plate .

[Lil Giants]

Good to see you making progress with your cnc equip Steve... ppl can clearly see by your trials & errors the reason why these complicated models cost what they do to manufacture! Great work! :cool:

[ihbuilder]

Thank you , Joe :) All the hair pulling is finally paying off , I just wish I new more about G code then I do :( . I'm thinking of taking some courses on it once I get caught up . Cam is nice but I wish I could catch the quirks before the program goes in the mill . Well I should have my axle shaft bar tomorrow then I can get these axles together finally :eek:

[doodlebug]

Wish I could remember where I saw the video for virtual run-for checking error's, I thought it was on the Tormach site???? Not much help!
But I did laugh the first time, when I heard that the BYU student's had to trial run there cnc project's in styrofoam first! Something about speed's and feed's? being way too fast, LOL! and this was back in the eightie's! CAN YOU SAY EXPENSIVE CRASH!

The part's look great, even if they take a while to make!

looks like its going to be a great build

[ihbuilder]

:o sorry I just had to take a weekend to my self:o but I was very productive 48 hr no nap time :p . I need to get my wheels made up and axles attached to the walkong beams so I can figure the pivot for the walking beams . oh heck nuff talk :o BTW This flippin cam is getin a ride back to PRC :mad:

You have to have "macro" on for the point and shoot to get that close.

[steamer]

Steve, are you using your wife's finger nail polish to clean that camera lens again? All kidding aside those wheels and rims look kick azz. Just had an other thought maybe it's all that midnight oil your burning is sooting up the lens!!!!
Rob

[Lil Giants]

You have to have "macro" on for the point and shoot to get that close.

And set the camera on something solid to elminate (or atleast lesson) the shake. Take several photos of each item & pic the best of the bunch.

[Papy]

...PS: a BIG thank you to Papy for the drawing of the front wheel :) I just scaled it and doc'd it up a bit and camed it THANKS PAPY...

Hi, Steve !
I am just happy this turned out so well for you. The result is awesome !!! Keep on the good work !

[ihbuilder]

Joe, Rob and Matt I have the macro on , It just does not focus up close :( my wife thought she got a good deal at 75 usd :rolleyes: not :mad: it could also be lack of natural lighting it's been scarce around here lately :( . today I woke to no power with the mill on all night fortunately it didn't surge :eck:

thanks papy wait till I'm done with the rear hubs ;) I'll have better pics by then

[9W Monighan]

Steve, I'm no camera guru but, This is what I have been using since Christmas. I am very happy with it. As you can see my macro can get really detailed shots. Steady hands is all you need or use one of those tiny tripods. I hardly ever use the flash in my shop. I took some pictures this weekend at camp in the dark with flash and they turned out very nice.

[kerst]

thats another to my list :) I've been looking . Ive deffinately need the tri-pod

I "made" my own tripod, just a block of wood with a 1/4" bolt and i clamp it to the work bench. I hardly ever use flash.

thanks Guys :) Chris they wern't that hard only issue I had was a dull #50 drill bit but then what you expect for drilling 564 holes :eek: It's the simple stuff that gets me for stupid little mistakes :(

thanks Lou , I guss thats why I have so many to make :eek:

Joe , my body tells me when to get some sleep or my wife puts me back in my cave :p the lathe is a charm :D with being able to cut .125 off the radius in 1 cut w/out the motor bogging or flat belt slipping will spoil you quick :eek:
now thats slow compared to the mill :eek: I hustle to keep up with the mill in making wheel components .

I'm finally getting the rear axles together :eek: just have to order my shims and longer bolts . gettin closer to driving this baby around :D:o

[ihbuilder]

OK Still the same cam :o but I got a little time ( well took :o ) to shim and set up the rear axles and assemble . they're upside down to assemble and pics , the walking beams belong on the bottom

Hey Steve, That's outstanding, don't worry about the camera. So in scale lbs? how much weight will they handle? Keep the the great work!
Later, Neil#2 aka doodlebug.

[ihbuilder]

Neil the truck is a 75T compacity I'm guessing the rears , from what I can see on the brochure , in excess of 100,000 # these < I can,t put enough in the box to max them out . I'm guessing 200+# the tires will flatten till I get that much on it .

[9W Monighan]

Very nice work Steve. I just got one of those differentials today to play around with. Might be a little big for my application though. Really nice detail with all the bolting of flanges on the pinion and the bearing caps on the beams.

[kyleandtavion]

Incredible so far

[kerst]

Just great!
kerst

[tc1cat]

WOW!! I forget to look in on this build for a few days and you go crazy with it! Those axles match the tires and wheels perfectly. Glad to see you have the mill and lathe programming down pat. :D Can't wait to see what is next :eek:

[ihbuilder]

thanks guys :) Lynn , I hope you can make it to york this comming jan. You'll get to see it in person working :D with some coal wear on the box by then :p .

[doodlebug]

Thank's for the info Steve, Still learning how much weight, the scale stuff will handle.

Looks great Steve. I have seen this thing in person and the pics don't do it justice as to how big this truck really is. The center sections of the rear axles are as big as a pop can. We need to get Steve to take some pics next to a recognizable object that most can compare the size to. Not to mention this thing is a piece of art.:D

[RCLogger]

That truck will be a real dirt mover, what are you going to build to load that MONSTER !

greg

[ihbuilder]

Greg ,I have a couple things planned ;)

I did some more today and got a vid outside before dark steering is not hooked up yet , and having the center drive shaft slipping :confused: I need to redrill the set screws so I can put the hpi screw pins in . I can lock the diffs if needed .

http://youtu.be/B9lopqTIl7s

[Lil Giants]

If you feel the open diffs aren't adequate, then try adding Shoo Goo to the differential, it works pretty good for limited slip without skidding much in a turn.

My KH 6x4 has the last axle locked, sometimes I peel the front tires with a load on. Freddy's red GL 6x4, I added Shoo Goo just to the last diff & it gets around as good as the KH. ;)

[ihbuilder]

Joe , I'm going to get the box on and fix the drive shaft sliping and see how it goes with a load on it . it's front heavy empty till you put 40-50 lbs in the box . I don't want it skiding on a ramp with a load of coal :eek:. the tires work good as duels but I think I'll need stiffer foam in the front . not only that I got a deformed bead that would never hold any bb's :mad: I don't have the walking beams right :( so I'm not getting good oscilation . I'm going to re make them in steel the right way with a little more detail to them :)

I took a few min. to tinker a little on the mack :o turns out I needed to shim the pinions :o . got the steering hooked up and ran a couple batteries through it . Empty , it did well , then I put about 50# of wet dirt in it and tried the hill :( the dang slipper clutch on the trany gotta go :( and It could use a litte mor reduction ( planetaries maybe Hmmm , I might attack that after Jan. cabin fever show ) here's a few pics of the body hing and top cylinder boss .

no vid again :o but It just ran its 1st coal job tonight :D 20 loads for 2/3 of a 55gal drum . worked well , no clutch slipping this time :) just a lousy formed front tire that kept coming off :mad: good thing I had a spare :) It still came off with the body totaly heaped ( 1.5 grain shovel full ) so I cut back to 1 . now to get it dumping on it's own . I need a loader now too ;)

[Lil Giants]

Do you get a refund for that bad tire?

Difficult to shoot video when you're having too much fun, eh? :D

I don't know Joe :confused: I could use it for another project and I'll just make bead locks for them . Yea , :D I'm working on a 990G or 988G monoboom since I have an extra set of wheels now :rolleyes: to load it . Its in the cad design process now . The assembly might go quicker then doing it the way I did before .

[sneaky-pete]

Wow Steve,this is going to be bad @ss when your done!

[ihbuilder]

thanks Troy , I finaly got the bumper on started in on the detail Steps/railing I need a part out of some .625 plate and it fit into the scrap area of what I had that some boom pieces where to be made from . So I nested them altogether ;)

tried to hual /unload my coal again :( but not worth the vid :mad: the dang thing is just too fast . I'm thinking 4 motors in the rear axles they're big enough . any how nuff cryin :p this is the idea behind the truck and loader
back my pickup to my bench and bridge to the upper section of the basement to unload my coal . some pics

looking in at the hopper for the furnace(55gal oil drum:p)

I guess I'm just venting a little :o O by the way , any one wanna race this thing :eek:

[JensR]

Great setup for the haul road!
Although, as your resident health&safety expert, I urge you to install rails to prevent your beaut from plunging to death :(

About the speed: Can't you squeeze in a reduction gear box?
Your axles are sweet, wouldn't tear them apart.
Also, while my grader runs on wheel motors, a shaft drive is more realistic for most machines.

Good luck either way!

[Lil Giants]

I wouldn't discard your axle setup either Steve. What's the total ratio of your axles? To go with a motor at each wheel in this trk you'd "have to" power the front axle too or the rear tandem drives would push you straight!

I've been using this wdc twin motor setup for more then ten yrs with great success and add on the 4:1 Carson (pmd rip off) behind a Tamiya 3spd & it's a slow moving stump puller. This setup is so slow in my trks that I rarely use 1st gear. I think your tires are less than twice the diameter of mine?

pmd bought out wdc's remaining supply of twin motor cases, so you're stuck at buying it at his ripp off price! Will the twin motor from Tmaxx, is it? fit the the Tamiya some how? The wdc is not a direct bolt on either, but an adapter is not difficult to make. I'm pretty Willy has some of these Carson 4:1's at a fraction of the price & Willy fabbed up some aluminum cases too like the originals. I use the original case (plastic) in my 6x4 trks & mount the 4:1 directly to the trans. You've seen a pic before, haven't you?

I'd try that out before doing anything drastic! 1st gear should give you the precision driving you want loaded & 2nd or 3rd to haul azz back to your reserve pile. ;)

I think the back of your pickup will be too small for your 990 to maneuver, you'll need a track hoe instead. :p

[ihbuilder]

" I think the back of your pickup will be too small for your 990 to maneuver, you'll need a track hoe instead. "

Joe , Thats on the drawing board too :D I'm going to keep the rears , too much time and sweat went into them :eek: . I had a slipping pinion in the fwd axle only cause some dummy put the shims on the wrong side :rolleyes: . I have to set my esc with the radio and maybe tweek it a little . The problem is no smooth opperation . the biggest PITA is the front tires rolling off the rims loaded (40 -50 Lbs tare weight ) . I going to try filling a set with silicone to see if that helps . Then I got to get these cylinders made .

[Lil Giants]

Silicone is mezzy!!! Try BB's to stiffen up the front tires.

[Brian in PA]

You have too much fun Steve!

Brian

[Espeefan]

That's a nice 1 ton dually you have there, Steve. I like the direction your Mack is headed too. I have to echo what the others said. Keep the axles. They are really nice. I'd suggest you just find yourself one big and brawny gearmotor to use as the transmission. We could calculate a good ratio for you, based on tire size, motor selection, and the voltage you want to run. As long as we know the motor's RPM per volt, or Kv rating, and an idea of how fast you want this thing to go.

[ihbuilder]

I'll have bb's all over the floor unlees I glue the bead . As soon as I turn loaded I roll the 1 tire right of . they look like they have 20psi of air in a tire that should have 100psi of air I got another plan , expasion joint for concrete slabs .

You have too much fun Steve!

isn't that the name of the game :D:p

thanks Nate , she's a work horse (bone stock) I got my speed issue taken care of . when I ran it the 1st time hauling 20 loads of coal it worked OK but I had a delay between fwd and rev . so I reprogramed the esc ( castle) to eliminate the delay . Also when I hooked it back up I desided to put the trotle on the throtle stick like evreyone else ( I know :rolleyes::o) not realizing you have to reset the radio with the esc when you change parameters on the esc :o . now the bone head that put the shims in wrong on the fwd rear also did so on the rear rear :rolleyes::o so I'm getting there :)

[ihbuilder]

couple weeks ago I tore the rears apart and re shimed them . I had to press a stel stop in the axle bore do to a change in direction since I machined the axle cassings :confused: I'm useing HPI savage ring and pinion assembly that has the shaft cups for the pin and ball shafts for independant suspension . well I machined the ID bore to keep them on :confused: not thinking the OD of the cups being close to the OD of the bearing :o . well I made my own axle shafts and eliminated the cups . So when I shimed up the diff and ran it a little the copper shims started working into the bore :confused::o Now she'll pull like H@!! :D you can't put enough on it to stop it :D . Tonight I took a little time and mounted the oil tank and pump whille my wife helped pack up some orders to go in the mail tomorrow ;) I also started on the cylinders a couple weeks ago . I did fix the front tire issue :) just added the foams from the distorted tires I have

I dont think anyone could imagine this turning out any better than it did! Its a scale masterpiece!

[ihbuilder]

thanks , Nick , DSM :)

well I diverged from scale a little :( once again my attempt to a telescopic cylinder failed :( (for now ) So some quick engineering and design , I'm making up a different set up to get er going with what I have laying around . still milling the rest of the parts . Yesterday built my battery box and tidied up the wiring in the evening .

thanks , I get tied up running parts for the semi trucks any more or sometimes a small excavating job comes up . the plan is to get this running then in order ( could change) 990 loader , td40b , pan/s or 385cl cat with a mass boom .

I let the mill run all night and since all I had was a .125 em after my 4mm em took a dump :( , woke up with the rest of my parts done :) now to fit the cylinders I have laying around .

Joe , I'm using a DX8 ,I have all my models on it for now till I get more radios . I'm thinking of a DX10 for the 385 and kobelco blade runner . I may glue the tires after I paint or find /cast like tom did more scale looking 1's . These are too wide to begin with . I'm using a 645MG servo for steering , I think it's about all it can handle loaded . I think It's drawing all it can thus interrupting the motor ,IDK :confused: Now to get this loader running :D

[modelman]

Truck looks really good steve-I like the way it bounces when loaded. Kinda like the real ones. Do you need me to make you some tires that will stay on the rims:D:D? Nice job.

[Snochaser]

Awesome, Awesome, Awesome!! You can see the torque, bout' does a wheelie. Great job Steve! What does it weigh as it stands now, how much do you thing the load weighed? I wanna try it, can I have a turn?

Ben

[sparkycuda]

Steve, you hit a home run with this bad-boy! It is large, but seems like plenty of power with the two motors, and acts like a real one - carries plenty of payload. It will look so much different when painted.

Want to see it first-hand sometime.

Ken

[Tamiya Cowboy]

Nice job steve that is a monster with tons of power to boot.. Can't wait to see it all finished in paint..

[SonoranWraith]

That looks just awesome. Slower would be more scale probably but sometimes its nice to be a little fast to get around. You need some solid tires for sure with those impressive loads!:D

thanks Tom , the tire should be narrower ( 1" wide ) to be within scale . But they work . I thought about glueing them after I get it painted (long way off yet ) I like the bounce too , it reminds me of the real 1's I use to watch waiting to get loaded at the quarry I seen them running in . those where m45's single axle . I think they scrapped them by now :(

I finish up a few things and loaded her up for a move to it's 1st job next sat. to see how she'll hold up . See if I can burn the ums pump motor up (not really want to )

I know Nate :o actually not , something else takes those funds and will for another 2 years :(:(:( I still got obligations to fullfill from when income was steady till '08' hit :( . It worked the best on sunday at cabin fever after I put in an external bec and started gluing the tires . I had to consentrate on feathering the throtle to keep the spinouts down :o . I meet a guy at the show who took the pic of the real 1 in the mack history book and knew of some of the smaller mseries in my area . He told me the M75's didn't like to steer just like the model . Someday , I'll be running out to NJ to see the real 1 in mack history book .

[JensR]

Awesome truck and great combo! :)

For the camera, you can put it onto a bean bag (which you can make yourself) or just something that is stable and a bit off the ground, like a few books or aluminium blocks ;) , this prevents camera shake.
If you then use the self timer, it will be even sharper.
Also, for close shots, using the macro mode might be necessary to get sharp shots.

thanks Steve , I'm trying to picture in my head where that pit is :confused: I heard the name of the co. somewhere . if you get on 209 from port carbon Pottsville head to Tamoqua Its like your driving through a trench . sometimes you can see some small drags working on the banks . all you see is the boom maybe a glimer of red/orange in the trees I've did some home excavations in those hills . 18% grade roads is the norm :eek: I'm wandering who really made the frames for those trucks . My dad worked for a co in 60's/70's (before I came in this messed up world :p ) that dug some of the fondation work at mack for the machines to make the rear axles on those trucks .I'm going to have to make a short trip to the mack histiric center someday , you up to it Scott ?

Maintenance day today :( then the barge came in with a load of coal that needed unloading ;) Altough it was just a little barge (250 ton ) :confused: I changed the motors to 65t lathe motors , what a difference :D still got some kick in her in 2nd but 1st is a nice speed for workin in a crowded area . I had some probs up loading to y tube so I up loaded to PB for now :o when uploading to y-tube finally worked the batts died in the cam :mad:
