Re: 777 HAUL TRUCK (1/12 size)
 

Wow this thing look awesome! (And heavy) The jet seems capable of making some amazing parts for you so far. Looking forward to updates :D

Re: 777 HAUL TRUCK (1/12 size)
 

Here is short vid of the truck...it is a bit slow but it will have to work for now....

MERRY CHRISTMAS EVERYONE !!!!!

Re: 777 HAUL TRUCK (1/12 size)
 

Wooo-hooo! Looks good and just in time to haul presents to the Xmas tree! I sure like the size of that. I don't think the speed is too bad? I guess you could always up you voltage or change the front sprocket if you thought it wasn't fast enough.



Kerry Christmas KP!

Re: 777 HAUL TRUCK (1/12 size)
 

Wo it's alive. It seems to turn all right, great job. With the 5 gallon pail you start to get the size of it. Ed

....I meant Merry Christmas not Kerry Christmas...

Re: 777 HAUL TRUCK (1/12 size)
 

DADSGARAGE-truck looks great. Turning radius is good, speed may be a bit slow but can be easily fixed. Have you calculated what the scale speed should be (ft. per sec.)? Keep the pictures coming.

Re: 777 HAUL TRUCK (1/12 size)
 

Wow, that looks fantastic. Steering seems to work just fine even without a rear differential. I cant wait to see this truck loaded to the gills lumbering up a haul road.

Re: 777 HAUL TRUCK (1/12 size)
 

The truck is slowly coming together...slowly.....ALM. would be a much better and lighter material to use for a bigger model like this...some day when I grow up I want to learn how to weld ALM.....:o:)

Thanks.....and yes it is heavy!!! Might be the only thing about this build that ends up being to scale...LOL....

Thanks.....it was nice being able to see this thing move around a bit, even if it is a bit slow, hopefully it will have enough power to move with a full load....I did try it with some weight on it but the rear tires are almost running flat because I only have foam in them now...they need air or more foam,deal with that later....


It is alive...well almost...finally remember to get vid of it...funny how tricky it is to hold the camera and radio at the same time,good thing I wasn't chewing gum...LOL...glad the pail was helpful I put it down for two reasons...get some idea of it's size and show the turn radius. It does seem to turn alright but this is with no load on concrete and no air in the rear tires,I think the tires might be slipping on the rims...one more thing to figure out later....

Re: 777 HAUL TRUCK (1/12 size)
 

Thanks......It does seem to turn alright at this point....the speed thing might be a problem, I do have it geared down now to what I hope will provide enough power when it is loaded...that little motor and gear box has a crazy amount power but it still may not be good enough considering the size of the tires and the size and weight of the truck....should have used ALM....but I can't weld ALM.....more like I just can't weld....LOL

Thanks...it is starting to look like a truck ,not very true to scale but more of a "looks about rightish" build.....I wish the tires were a bit bigger and wider...
I really want to see this thing finished and hauling a load as well !!
(besides I need to get started on the shovel so someone stops hounding me about it....Reg...LOL:cop:)

Re: 777 HAUL TRUCK (1/12 size)
 

This is a really cool truck! Access to the waterjet really helps with correct dimensions and repetitive cuts - and with great accuracy.

I've re-read all the pages and did not see a reference to where to got the inside steering gear sector.?.? Saw the servo info with pinion gear. Did you make the big gear sector?

Anyway, awesome truck.

Have you looked at solid amerityre tires?
Cheers, Neil.

Re: 777 HAUL TRUCK (1/12 size)
 

Hi Ken glad you like the truck so far......yes the steering segment arm is also cut with a waterjet, a 32P internal spur gear is about the smallest the machine will cut and the root section of the gear is a bit off, the reason is the size of the kerf cut by the nozzle which is about .030" so that means the smallest radius it can cut is half that size or .015"...Hope this makes sence...

Here are a couple more pics of the steering gear set up.....a few things need to be done with it yet....I just have bolt in it now and still need to make a better pivot shaft for it etc......

Re: 777 HAUL TRUCK (1/12 size)
 

Sorry Neil, I don't think they will work as they were made for a "hand Truck" not a "haul truck".:p

Those would make some nice 1/10th loader tires if the tread was a little different.

Re: 777 HAUL TRUCK (1/12 size)
 

Thanks for the link Neil...I was looking at this type of tire when I started the truck....a solid tire would be great....but they are a bit too wide, the height is better though...too bad the tread wasn't different because I think a guy could machine off one side to make it narrower..maybe...wish it was a diamond tread......

Re: 777 HAUL TRUCK (1/12 size)
 

Got some work done on the hand railing for the deck...much the same as the ladders...next will be the side railing and the small deck next to the cab....

Re: 777 HAUL TRUCK (1/12 size)
 

Wow, you've made some great progress on the 777. I like the detail you've been putting into the truck. The handrails and ladders look really good. The 5 gallon bucket really helps put things into perspective, on it's shear size. No doubt it will be a very well built, and heavy model. Nice work!

Re: 777 HAUL TRUCK (1/12 size)
 

Thanks!!! Adding the details seems to be the biggest challenge but the finished result is always rewarding. Hopefully it is well built...LOL...one thing is for sure...it is heavy!!! :eek::o

Re: 777 HAUL TRUCK (1/12 size)
 

Got a few more "details" done today..... the side hand railing....

[IMG]http://i1291.photobucket.com/albums/...ps7687665b.jpg[/IMG]

Slowly trying to get this thing to look a bit more like the real thing...

Re: 777 HAUL TRUCK (1/12 size)
 

That's nice! Details always sell the appearance of a model. Are you planning on welding all the super structure components together? I can see some tack welds here and there, and some screws in other places. I would think a lot of the tack welds are probably strong enough for the components that won't be stressed, like the cab, fenders, ect. A little body filler to smooth the joints over, and it would be ready for paint. I wish I was a little better at tig welding. I do all right with SMAC welding. Not to much experience with tig.

Re: 777 HAUL TRUCK (1/12 size)
 

First attempt at the small deck/walkway beside the cab and the hand railing. Something about this just isn't right....think the walk way is too wide, trying to build this all without a scale model to use as a reference or blue prints is tricky, looking at 1:1 picture can only help so much, and many picture are not at the proper angle to get a good reference from...fun fun....very frustating at times!!! More time is spent looking at what has been added and trying to figure out why it doesn't seem to look right....or maybe it's a combination of a number of things that aren't right which make finding the problem a total DRAG !!! I must say...my hat's off to the scale builders!!!! Hope you don't mind my simple not so scale like build....learning all the time!!!:D:o

Re: 777 HAUL TRUCK (1/12 size)
 

Details details....yup it does help sell the appearance...just wish it wasn't so #%$@*^& frustrating....LOL...

All the parts you see that have been bent are done by leaving a small amount of material in place, just enough to hold it together and make it easy to bend by hand, all these areas will end up getting a full weld.
They will be mig welded (.023" solid wire) "down hand" to help reduce the amount of heat and avoid to much warping...Tig would be much better...my Tig welding skills are low...scratch that...more like zero !!! :o:eek: Just one more thing to learn when I grow up!!!:D

Re: 777 HAUL TRUCK (1/12 size)
 

A BIG WOW===it is looking good.

I see a valve stem. Are the rims 4 in dia with tube type tires?

Ken

Re: 777 HAUL TRUCK (1/12 size)
 

Are you kidding me? That walkway and railing along side the cab looks awesome! I'd say it's quite scale looking, but then I do not have a 1:1 photo to compare it to. One benefit to using steel for all this is that it's more durable. Clamping up aluminum parts with vise grips would definitely mar the finish of the surface. Plus like you said, it's easier to weld.

Re: 777 HAUL TRUCK (1/12 size)
 

Thanks!!!

Yup , I see it too...:o....I have this rim on the wrong way OOPS...LOL...valve stem should be on the inside, and yes the rims are 4" with tubes....

Re: 777 HAUL TRUCK (1/12 size)
 

Maybe it's just me but something just doesn't seem right....half the problem is knowing what it looks like when seen from above and or from different angles...most times all the pics I can find of this thing are looking up at the truck and not a birds eye view, maybe the real deal looks "goofy" too from some angles...LOL...not sure ??!!
Using steel does have it's advantages...but you pay a price for the added weight!!! A truck like this is meant to carry a big load..not be a big load..LOL

Re: 777 HAUL TRUCK (1/12 size)
 

I drive real 777D's at work and the walkway looks right on. On the real thing the walkway looks large until you try and squeeze my butt on it then it gets pretty crowded.

Awesome build by the way.

Re: 777 HAUL TRUCK (1/12 size)
 

Awesome!!!! Someone who actually knows what this rig should actually look like...how wide is that walkway??? I have this at a scale of about 18" wide...somehow I think the short front section is narrower than the side section is....if you could take a measurement for me that would be GREAT !!!!

Glad you like my attemt at building this truck....any pics and or suggestions on this build will be helpful and very much appreciated!!!!

Re: 777 HAUL TRUCK (1/12 size)
 

One more small detail that got done today...the mud flaps...thankfully they look about right!!?? ;):D

Re: 777 HAUL TRUCK (1/12 size)
 

You're a building machine my friend! Kind of reminds me of someone else I know:confused:...You don't sleep much either do you?

Your truck is looking awesome! I'd love to perch my Volvo onto a pile next to it and load it up!

Oh, be careful offering to cut out some pieces for me...I may just take you up on it!lol

Re: 777 HAUL TRUCK (1/12 size)
 

Sleep??? What's that??? Oh I know....something you do at night when it's dark....LOL....most of the time I think I work in my sleep and sleep while I work...HEEHEE...that almost makes sence!!?? ;)

The offer to cut you some parts still stands...however...just after I hit the "submit reply" button I thought about what I may have got myself into and the possible long list of "goodies" you would most likely ask for.....I'm actually kinda surprised you didn't???...yet...LOL...thought for sure I set myself up on that one!!! :eek::D;)

(Really if you want/need something send me an e-mail with dimensions etc ,I would be more than willing to help with a future project.....providing it's not a full blown build!!!! :eek:;):D) )

Keep it up!
Cheer's, Neil.

Re: 777 HAUL TRUCK (1/12 size)
 

Yes I have seen that....way cool....once I'm finished building this haul truck I have considered building another 777 truck c/w trailer for moving my D11,and the future PC1250 shovel....or at least a retro fit for this truck with that set up. It would be a great way to move this heavy stuff around!!! One thing at a time....so many things a guy wants to make!!! LOL!!!!

If I did build another 777 c/w trailer I would also consider this bottom dump trailer idea as well...just something different...but again one thing at a time, funny how working for a living always gets in the way of the fun stuff!! :cop:

Re: 777 HAUL TRUCK (1/12 size)
 

Hello you are doing a great job the walk ways and rails look awesome. You are moving right along there no mold growing on you. Keep up the good work. Ed

Re: 777 HAUL TRUCK (1/12 size)
 

We are not allowed to have camera at work (get caught with one and you are probably going to lose your job). I will see if I can get some dimensions when I go back to work (work 7 on/7 off) but 18inches sounds about right.


if you are around the Edmonton area you could see these guys http://www.heavymetalequipment.ca/Home.aspx they rent them. Or just get them to deliver one to you and take some measurements, its only $32,000 a month plus delivery.
