My RS700L build

[Lmackattack]

Just wanted to show what im building. This has been a long time project in the making. I bought my KH the first year it came out. Its seen about 4 stock bodies and such thru the years and I always wanted to make a model of my Mack truck. I recently started to bring it back from the dead and will be converting it into my 1:1 rig, a 1977 Mack RS700L day cab

Here is what I have done in the last 2 weeks.

upgraded the drive line with RC4WD shafts,carrier bearing and locker spool in the RR axel. moved 5th wheel forward to reduce the push of the locker spool. It still needs to be adjusted a little more forward.

New RC4WD 2 hole budd rims and roady rubber on the rear axels
I also tinkered with the stock tandem springs and cut axel stopsto get about 1.250" of travel

I installed new low profile servos and added spacers so I can move the motor/trans forward.

started making the Mack air tanks, Batt boxes and 126 gallon fuel tanks

a side project is building a 48' Flat bed. I also moded the springs on this trailer so I get alot of articulation. with my truck/tractor spring set up I can really get thru the off road with ease. it will drive right thru the grass yard and not get the stock open diff wheel spin issue.

the cab Im having some issues with. years ago I started to mod the stock King cab to make it into a R model. I think I need to start over with fresh plastc templates as the R model has so many curves to it that its a PITA to just attempt to get it right with bondo.

well thats all for now....I have a RC4WD 55 turn motor and RC4wd front budd rims on its way for next weeks install.

I also want to give a big thanks to dabears,I met up with him last week becase I had lots of questions getting back into this hobby. He pointed me straight and got me rolling in the right direction


more to come next week!

[Lmackattack]

made some end caps tonight for my fuel tanks, if your asking...Yes this is the Mack western style tank with a "bulls eye" on each end.. I think International used them as well on their Eagle cab overs.

The cool thing about this build is that the way Mack built their trucks I can use a Mack Cruiseliner cab over or RS700L on the same frame as many of the exterior components ie air,fuel tanks were placed in the same spot from Conventional to Cabover.

[Espeefan]

Cool build you have going here, Lmackattack. I am sure the challenge will all be in the cab! Something I could never imagine to attempt myself, but there are some really talented cab builders on this forum, who could probably help you out, or offer some good scratchuilding advice. Your 1:1 Mack looks clean and mean. I've never seen one with dual air intake tubes coming off one air cleaner.

[kornfed]

http://www.kustomrctruckz.co.uk/ This place has a Mack cab based off the movie convoy. Don't know if it's the same cab as your truck, don't know if you knew about these

Dad's '79 Mack 300 had two intake hoses on the air cleaner, His '85 with a 350 4-valve Mack only had one.

Thanks for the heads up... I did see that cab a few weeks ago. It looks nice and if I can't fab up my own I may call them...



Regarding the twin tube breather....the one tube feeds the turbo the other feeds the tip turbine for the side mount charge cooler. These twin tube breathers were fitted to the late 70s early 80s 285, 300+, and early 300/350 Mack motors with charge air cooling. mid 70s Mack's with the 285 or 300+ would have fed the charge cooler via a backwards facing hood scoop on the hood with a Coffey can style filter just under the hood. The style you see in my pic was the better model as there was less stuff to mess with when doing maintance on the engine...

Some other versions of twin tube air cleaners can still be found today in very cold and snowy parts of north America. It's used to suck warm air from under the hood and reduce clogging with heavy snow conditions.

[dabears]

Glad to see the trailer is coming along!! Its looking great! It was a pleasure meeting you and showing you some tips and ideas!

[doodlebug]

Thanks for the explanation, I got rid of all my older Mack manual's in 97, after buying my CL 713. My 88 RD didn't have that twin hose air cleaner, just a pre cleaner on top of the air cleaner can.
Cheer's, Neil.

No problem...I think the twin tube air filters went away when Mack went to front mount intercooling, this was around 1983? . This again made maintance access better as it removed the tip turbine and side mount cooler from the engine. The one thing I like about the old tip turbine maxidynes was it had a nice whine to it when it was waking up. 1st and 2nd gear were quick and you could hear it spool up half way in 1st,pause thry your shift...then wind out in 2nd..

Back then every engine make had its own song...not so much today

[Lmackattack]

Here is the youtube mod I made today...

I removed some metal off my steer axel to get just a bit more cut out of the wheels. I'm about 2mm from hitting the springs. 33" turning radius on a slippery tile floor and locked rear axel. Not bad!

[Lmackattack]

Made a little progress last week on the R model Cab before I left for Cali.

Still need allot of work but its taking shape.

If anyone knows who can make a mold or a 3d copy of this cab when im done I would be interested in talking to you/them in attempt to reproduce them.

thanks for looking

[dabears]

Looking MUCH better then when I saw it!!! its gonna be bad A$$

[Lmackattack]

THANKS MAN. its taking shape pretty quickly..to bad your leaving Chi town. I bought 2 King haulers off ebay last week. Now I will have to find somhe more local members to meet up with....Just when I thought I had a good local trucker to hang with.......He moves!.. LOL!!

Well you do drive thru Arizona sometime on your route I would assume. lol

[Espeefan]

Looking good L Mack. The new cab revisions are working well. Thanks to you and Craig, for the history lessons on the dual tube air cleaners. Learn something new everyday! By the way, Chicago is about 4 hours away from me, so you aren't exactly local, but I've been around there before. What side of the city are you in?

[Lmackattack]

I live in the northwest burbs to be exact. About 25 miles north of down town. Don't be fooled tho... Plenty of traffic still here lol.. I live in a town called buffalo grove. If your ever near here let me know...

[tracksntreadslou]

These are one of my Favorite trucks ..Nice work with the cab so far ..I still see a few of these older macks around ..and some of them bragging that they completeley rotated the odometer..Pretty common for some of these trucks making a million miles ..What does the odometer show on the 1977 1-1

[Lmackattack]

when I bought it back in 2005 it showed around 850,000, the speedo was shot , it was bouncing badly and hard to keep up with how fast I was going. so I replaced it with a newer one out of a wrecked truck, The old Macks were great trucks. we have plenty of old R models still in Chicago and see alot in other Big citys as well. Its an all buisness no frills kind of truck.

[Lmackattack]

Let's get this build going again....I saw last week on shapeways that someone makes a RS700L hood , I have been slowly making my own cab and hood out of a king hauler cab but you can't beat the printed detail. So I bought a 3D cab,hoodother misc parts for my build.

I had used this trucks frame for my 6 wheeler build so new rails are on the way here to stretch a globe liner out. This build should move along now that the cab and hood are made....perfect timing as my Mack 6 wheeler is almost done

[Espeefan]

Wow. That 3D printed cab is awesome. I would love to build a truck with a 3D printed cab, but lately I can't even finished what I started, so I better stay focused on that!

[Lmackattack]

Yea luckily I have had some free time. To work on these trucks....I'm not going to lie....it's nice to have some days off but we will be full tilt come spring... Here is a little update.

Got my aluminum fuel/air tanks mounted, batt boxes made and ready to polish them to match the tanks. 3D Cab is test fitted with the lower fenders cut off and new grill was made as the 3d one is not 100% correct. I Made some front fender splash guards and a new bumper. Started on a cab visor and it's almost done.

I Got some half fenders coming this week and hopefully some mule ear pipes when there back in stock.. I have a air cleaner and horns on the way from a fellow member...hopefully in a few more weeks it will be done..

[wolfws6]

Looks awesome, just like the real thing!!!!

[Lmackattack]

Thanks for the kind words guys




Well i Got my sleeper painted last night. Little more cab detail work,lights etc...and she will be done. It also finally warmed up to about 22 degrees today, no melting snow or salt present so I had to seize the moment and take it out for its first pull around the front yard.

[cabs]

That came out real cool.

[Supermario]

What a great looking fleet bud!:cool: Great to see something unique and not mainstream builds. Very nice Mack fleet for sure:)

I like the bricks for a load. They look like large cut slabs from a rock quarry. I might have to use that one this summer.;)


Mario

[plow jockey]

Love those macks! Great job on your fleet.

[Lmackattack]

Yea, this is awesome! great job :D I love the Mac!

[BRICKNICK]

You did an amazing job man. It's such a clean sweet build. I posted a few of your pics on the instagram page I made to promote this hobby and this forum and it was such a big hit I had one guy as me if he can order one and another guy asked me how much to buy it from me. I then explained like I do repeatedly too people who can't read, that the trucks aren't mine they are all built by the talented builders and members of this forum. But anyways all the construction guys love your mack builds man, keep up the good work.

Thanks for the kind words. and love to keep the hobby going even if it just gives people ideas..what page did you link it to? I had a buddy email me a pic from a site called Scale_trucking_n_Construction. Thought it was kinda cool how fast things get around the web!

He dident know I built it but he knows I own a similar looking Mack.

[BRICKNICK]

That is my page...lol scale_ trucking_ n_construction on instagram. It's apage dedicated entirely to the hobby we all love so much. It is nothing but pics from here and my own rc trucks and a bunch of videos I get from a video site that's linked to YouTube. I've been trying to get some of our memebers here to join instagram n follow the page and a few guys have already.

[Lmackattack]

ok cool, I just joined instagram , I will start following your collection of pics.

[Lmackattack]

here is a "slow motion " video I made over the weekend. thought it would be coolgto catch the tractor and trailer suspension at work. Sorry if you don't like the music. the original sound was a lonely drone when slowed down so I dubbed in a song


http://youtu.be/RMvbfakxPcs

[Diesel Demond]

Wow man great job looks so cool. i ate a whole bag of pistachios watching your video great work. only if you could edit in some black coal rollin when your driving. lol i would be proud to own that!!
