old comp truck turned scale truck (the rebuild!)

I decided to start a new thread since i completely rebuilding this so for those interested here is the first thread: http://www.rccrawler.com/forum/1-9-scale-rigs/280059-old-comp-truck-turned-scale-truck.html

After beating the old girl thoroughly over the winter the truck started to show it's age

http://i229.photobucket.com/albums/e...k/IMG_1252.jpg

http://i229.photobucket.com/albums/e...k/IMG_1253.jpg

Something in the front doesn't look quite right huh?

http://i229.photobucket.com/albums/e...k/IMG_1254.jpg

yep the links were worn out and i couldn't keep the suspension from flopping. From the beginning i knew it was only temporary as i had full intentions to make the uppers more scale looking.

I also had a little trouble with the rear axle. Oops!

http://i229.photobucket.com/albums/e...k/IMG_1255.jpg

All this combined with the need to replace the chassis with rails to keep it in class 2 i decided it was time to tear it down and rebuild.

the first step was obviously to tear it apart and within 15 minutes i had it to bare bones

http://i229.photobucket.com/albums/e...k/IMG_1256.jpg

And was left with a pile of wrinkled sheet metal

http://i229.photobucket.com/albums/e...k/IMG_1257.jpg

next i blasted it

http://i229.photobucket.com/albums/e...k/IMG_1300.jpg

and cut off the frame

http://i229.photobucket.com/albums/e...k/IMG_1301.jpg

http://i229.photobucket.com/albums/e...k/IMG_1303.jpg

I'm keeping the rails for another project more TCC orented

then i bent up some rails

http://i229.photobucket.com/albums/e...k/IMG_1306.jpg

and mocked them in place

http://i229.photobucket.com/albums/e...k/IMG_1304.jpg

http://i229.photobucket.com/albums/e...k/IMG_1305.jpg

with the rails situated i did some figuring and started on the center skid. I began with some square stock, narrowed then cut into a U and tacked to some sheet metal

http://i229.photobucket.com/albums/e...k/IMG_1372.jpg

then i fully welded it and trimmed the U out.

http://i229.photobucket.com/albums/e...k/IMG_1373.jpg

http://i229.photobucket.com/albums/e...k/IMG_1374.jpg

Next up was the axles. I made a 3 link truss

http://i229.photobucket.com/albums/e...k/IMG_1398.jpg

I fixed the rear shaft, shaved both of them down and added the trusses

http://i229.photobucket.com/albums/e...k/IMG_1399.jpg

http://i229.photobucket.com/albums/e...k/IMG_1400.jpg

and finally mocked it all into place

http://i229.photobucket.com/albums/e...k/IMG_1402.jpg

And yes I'm moving the tranny under the hood and running my homemade T-case from the willy's build to get a full depth interior and more scale points.

In all not to bad so far. I stole the lower links from my sportsman truck so the fronts need to be a little shorter but otherwise it is coming along good.

Just get sick of this rig already...I'm ready or it to be in my stable"thumbsup"

Awesome! I love this thing! Not much time left though, you better get moving.

You must be referring to the MSD scale nats. unfortunately I'm not going to them, although I wish i was. No my next scale comp isn't for another 2 months so i have plenty of time.

always love seeing any work on this rig

Thanks. Here is more.

Small update. After trying to align everything by eye and just not being satisfied with the result, I looked for something to make a jig and found these PVC channels left over from when i installed new windows last summer.

http://i229.photobucket.com/albums/e...k/CIMG0155.jpg

with everything square and true i added tabs to mount the skid plate

http://i229.photobucket.com/albums/e...k/CIMG0157.jpg

Then, after aligning the skid using the jig, trimmed it to fit

http://i229.photobucket.com/albums/e...k/CIMG0158.jpg

wanting to keep everything flush, and make it removable, I drilled, tapped, and countersunk 8 2MM screws.

http://i229.photobucket.com/albums/e...k/CIMG0161.jpg

That's it for now

Got a bit more done

Moved onto the upper links. Made some tabs for the front and tweaked them to keep the rod ends strait

http://i229.photobucket.com/albums/e...k/CIMG0169.jpg

http://i229.photobucket.com/albums/e...k/CIMG0170.jpg

Then since the frame kicks up higher in the rear I added a plate inside and ran the mount right through the frame

http://i229.photobucket.com/albums/e...k/CIMG0171.jpg

overall shot from the side

http://i229.photobucket.com/albums/e...k/CIMG0168.jpg

Next is the front shock hoops. I wanted All-Pro style hoops so i bent up some tubing

http://i229.photobucket.com/albums/e...k/CIMG0172.jpg

Tacked them to some bar stock

http://i229.photobucket.com/albums/e...k/CIMG0174.jpg

fabbed up some tabs

http://i229.photobucket.com/albums/e...k/CIMG0173.jpg

brazed them to the tubing

http://i229.photobucket.com/albums/e...k/CIMG0176.jpg

then tacked it in place

http://i229.photobucket.com/albums/e...k/CIMG0175.jpg

I won't know if that's the final position until i get the rest of the mounts done and get the whole thing sitting on it's own with all the weight added.

That's it for now

this thing is the bees knees, awsome work!!!"thumbsup""thumbsup"

Got a little more progress on this.

After i finished the front hoops i added upper mounts for the rear shocks

http://i229.photobucket.com/albums/e...k/CIMG0388.jpg

then i made a temporary mount for the tranny

http://i229.photobucket.com/albums/e...k/CIMG0387.jpg

http://i229.photobucket.com/albums/e...k/CIMG0386.jpg

even got it to fit under the dash

http://i229.photobucket.com/albums/e...k/CIMG0389.jpg

http://i229.photobucket.com/albums/e...k/CIMG0391.jpg

now it's finally sitting on it's own.

http://i229.photobucket.com/albums/e...k/CIMG0385.jpg

but i'm not to happy with the flex in the rear

http://i229.photobucket.com/albums/e...k/CIMG0384.jpg

But i got to test it a bit and the drive train works great and at this point that's all i care about.

More later.

nice work so far."thumbsup"

holy man a rebuild already???? hahaha geez your hard on these things!!!!

looking good im excited to see it finished."thumbsup" i havent done nothing with mine, got my shock hoops bent up and just need to tack them onto the chassis.

more progress finally.

I wasn't satisfied with the rear travel after i took it for a spin. The shocks were more vertical then before and they also didn't look very scale that way so i went a different direction.

I started by making some tabs and adding tapped holes for adjustment.

http://i229.photobucket.com/albums/e...k/CIMG0932.jpg

Then i added them to the 3 link truss i made earlier

http://i229.photobucket.com/albums/e...k/CIMG0933.jpg

here it is in place

http://i229.photobucket.com/albums/e...k/CIMG0934.jpg

Next i needed an upper mount. I've seen others use the tubing through tubing method so i thought i'd give it a try.

Started with 1/4" dia tube and drilled 2 3/16" holes in it

http://i229.photobucket.com/albums/e...k/CIMG0936.jpg

Then slid tubing into it

http://i229.photobucket.com/albums/e...k/CIMG0937.jpg

then i drilled holes in the frame

http://i229.photobucket.com/albums/e...k/CIMG0938.jpg

and finally brazed it all up

http://i229.photobucket.com/albums/e...k/CIMG0939.jpg

Here it is with the shocks attached

http://i229.photobucket.com/albums/e...k/CIMG0947.jpg

looks a lot cleaner now.

http://i229.photobucket.com/albums/e...k/CIMG0944.jpg

And the flex? now this is much better!

http://i229.photobucket.com/albums/e...k/CIMG0945.jpg

http://i229.photobucket.com/albums/e...k/CIMG0949.jpg

Here it is with the rear fender on for a better idea of how much droop it has now

http://i229.photobucket.com/albums/e...k/CIMG0950.jpg

i need to add bump stops yet but otherwise I'm pretty happy with the result.

Next up is the rear tire carrier.

In an effort to get the most points with the new scale rules, i decided to move the tire carrier to the bumper but not wanting the tire to sit high or hang out over the rear i decided to think outside the box a bit.

The first thing i needed to do was some chopping

http://i229.photobucket.com/albums/e...k/CIMG0952.jpg

then i bent up some tubing and brazed some small tubes on the ends

http://i229.photobucket.com/albums/e...k/CIMG0956.jpg

next i made the tire mount by brazing a screw to some tubing and coat hanger wire to the nut

http://i229.photobucket.com/albums/e...k/CIMG0957.jpg

then attached it to the mount

http://i229.photobucket.com/albums/e...k/CIMG0958.jpg

to attach it to the bumper I welded a screw to the bumper.

http://i229.photobucket.com/albums/e...k/CIMG0959.jpg

and here is the tire in place. now i get the scale points without any impact on the performance on the truck

http://i229.photobucket.com/albums/e...k/CIMG0961.jpg

now here is the neat part

http://i229.photobucket.com/albums/e...k/CIMG0955.jpg

Yep, it swings out.

http://i229.photobucket.com/albums/e...k/CIMG0960.jpg

finally to attach the other side i drilled a hole in the bumper

http://i229.photobucket.com/albums/e...k/CIMG0962.jpg

Added a nut

http://i229.photobucket.com/albums/e...k/CIMG0964.jpg

and screwed the carrier on

http://i229.photobucket.com/albums/e...k/CIMG0963.jpg

I'm getting closer to completion but i still have a bit to do. more later.

you suck! :flipoff: 'Gonna be ready for Sunday? I might have to but some tires for the Honcho so I can run against you in class 2. "thumbsup"

I'm trying. I might run it but it's not going to be done by any means.

I got some more work done on the truck

When i had the suspension worked out, and with the spare tire taking the place of the tailgate, i started looking at the tubing left and decided to start over with the bed of the truck so out came the cut-off wheel

http://i229.photobucket.com/albums/e...k/CIMG0966.jpg

then i added a cross member to the back of the chassis

http://i229.photobucket.com/albums/e...k/CIMG0967.jpg

next came new tubing

http://i229.photobucket.com/albums/e...k/CIMG0968.jpg

and with the fenders mocked in place, tacked the bumper on

http://i229.photobucket.com/albums/e...k/CIMG0969.jpg

next came supports for the tubing that go around the lights

http://i229.photobucket.com/albums/e...k/CIMG0970.jpg

http://i229.photobucket.com/albums/e...k/CIMG0971.jpg

Last to go in was the mounts for the battery box

http://i229.photobucket.com/albums/e...k/CIMG0972.jpg

and here is the box in place

http://i229.photobucket.com/albums/e...k/CIMG0973.jpg

With everything in place i tore it down and brazed all the joints then put it all back together with the old body for some test runs to work out the bugs

http://i229.photobucket.com/albums/e...k/CIMG0977.jpg

http://i229.photobucket.com/albums/e...k/CIMG0978.jpg

http://i229.photobucket.com/albums/e...k/CIMG0981.jpg

http://i229.photobucket.com/albums/e...k/CIMG0982.jpg

http://i229.photobucket.com/albums/e...k/CIMG0983.jpg

After a few test runs i had a reacquiring problem.

http://i229.photobucket.com/albums/e...k/CIMG0985.jpg

The Traxxas shaft from the tranny to the T-case was just not up to the task for obvious reasons, so to alleviate the problem i decided to modify an MIP shaft but it would need some serious surgery to match the length of the Traxxas shaft.

http://i229.photobucket.com/albums/e...k/CIMG1007.jpg

http://i229.photobucket.com/albums/e...k/CIMG1009.jpg

in a nutshell i had to cut the tube section out of the outer shaft keeping the splined section. then cut the smooth section, and a bit from the end, off the inner part

http://i229.photobucket.com/albums/e...k/CIMG1013.jpg

Then i bored the bell and machined the shaft to fit

http://i229.photobucket.com/albums/e...k/CIMG1015.jpg

http://i229.photobucket.com/albums/e...k/CIMG1018.jpg

here is is mocked in place

http://i229.photobucket.com/albums/e...k/CIMG1019.jpg

then i broke out the TIG and burned it tigether

http://i229.photobucket.com/albums/e...k/CIMG1022.jpg

http://i229.photobucket.com/albums/e...k/CIMG1023.jpg

http://i229.photobucket.com/albums/e...k/CIMG1028.jpg

Now i have BEEF!

http://i229.photobucket.com/albums/e...k/CIMG1029.jpg

A little more testing and i'll be ready for paint and details.

impressive sir. keep up the great work"thumbsup"

This build is looking great can't wait to see the finished product!
