G-machine of a different.......scale?!?

This thing has risen from the ashes. I've got the base for the rear tires formed, I think I've figured out how to create a fast 90/90 intake, I've spent most of today working on the front sub frame, waiting on some molds to dry. I re-worked the heads, removing valve covers and making new masters for each. I'm waiting on the mold for the heads and the mold for the tread blocks for the tires to cure so I can start casting those pieces. The tires will be TOYO proxes4 20"front and rear. I am hoping to stagger the widths front and rear. I'm still looking for someone to machine some wheel "hoops"for me without charging an arm and a leg....

First off the tires. I'm not sure if there are pictures hiding in here somewhere, but before all of my stuff got packed away, many moons ago. I had created a sidewall for a tire. I pulled that out, cleaned it up, and poured a mold. I took 5 of those and created the skeleton. 2 on inside and outside pressed together and one in the center for some support. Next I heated and wrapped a 2cm wide stip around the skeleton and glued it into place. Then I stacked 2 1.5mm strips and wrapped them around the center of the tire for the center rib. Once that was glued into place. I sketched the 3 different tread blocks that I needed and poured a mold. I'd much rather use a little casting rubber and be able to create identical pieces, than try to recreate them all by hand. My goal is to have a front and rear master, and cast them in casting rubber, we will see how that goes.





Next is the front sub-frame. I had lots of issues with this, I re-did it about three times today, and come to find out, it is the chassis that is warped, not my scratch built sub frame. Once the kit is all together and everything is tweaked properly it should be just fine. There is still a lot of work to do with this. The bar where the engine will mount to still needs to be constructed, mounts for both the rack and pinion steering, and the a-arms and suspension need to be done.

Nice to see some progress, keep it coming...

Thanks. Its taking a lot longer for my RTV molds to cure than it should. That is holding up a lot of progress. I've sorted out the coil overs for the most part. I need to get to home depot and pick up some larger heat shrink tubing to finish the effect. I'm doing the majority of this stuff without a mill or lathe, so its using different techniques to create the "look"of the part, such as threaded bodies for the coil overs. I started work on the a-arms last night, but I think I'm going to have to re-stock my plastic rod and use that instead of brass. Does anyone have an idea of the OD of the tubing for tubular control arms?

Glad to see this plastic mutha resurrected. Keep us up to date.

A little more work done on this thing. Got it all sanded down and some fresh clear on it. I left out the trash this time, but a nice coat of orange peel took its place, gotta love the learning curve. The big update, well atleast the pictures are for the front suspension. I've got the base for the passenger side upper A-Arm done. I modeled a Detriot Speed and Engineering unit. The frame is different size brass tubing soldered together. The finer details will be done with styrene. I did this by first bending the outer bars, then it was all tacked to the kit a-arm to keep the proper placement. Then everything was soldered together. It ruins the kit part, but makes for a great template!

Awesome.

Thanks. Still needs quite a bit of work. I need to re-stock my styrene stash before this makes much more progress. Oh and my tools need some upgrades. Now if I could only find a willing machinist to help me out.
