demo cars!

[Metal Masher]

Some of you may have seen my metal bodied trucks such as my test rig

Project True scale test rig

Joe's Flatty

Joe's flatty The revival!

And the comp tuber

Well for a while now I've been wanting to build some demo cars the had realistic damage so I decided to make some using some old RC10 components I had lying around

First off I had some simple flat chassis made up at work out of stainless




this gives me 4 equal cars for a kind of "spec" demo

then I installed the mechanical parts I had lying around



and dropped in some electronics to make sure it all worked good



Then I started the bodies

I used the same molds I used for my wrinkles project since they were the simplest to make



then I glued them together to make the basic shells



Next I got started on the floor of the cab. I crabbed some crappy aluminum and cut it to the shape I needed



then glued some reinforcement



to make the supports I took thin strips of aluminum and formed them over 1/4" square brass tubing



Then I test fitted it to the chassis



then clamped the body on to see how it fit



Looks pretty good I think

More to come!

Very cool! I always like your builds... This one sounds like a blast. Only thing I worry about is bending the frame in a collision.

[crunky]

very cool, and great skill to make those.

cant wait to see some more carnage pics !

[sbchero]

thats great. demo rc derby.

what thickness is the body made out of?

Aluminum baking sheets just like my other builds. it measures about .006" thick

LOL yah, that's kind of the point. I made the frames slightly weaker then the kit ones on purpose just to see if they bend like a real truck when hit hard. we'll see

[Crawler Noob]

looks like fun to beat those cars

[karlos]

LOL, cool. Can't wait to see the video!

[flybynighter]

i see awesome fun coming out of this ...... cant wait to see the pics

[Metal Masher]

Thanks guys!

Well to make the truck as realistic as possible I needed firewalls, so I bent up a simple front one



Then I formed the rear of the cab and gave it some ribbing for strength



Then tested the fit



I also needed inner fenders of course





Then I made a rad support which consisted of a body mount made of heavier roof flashing




glued to the rad support shape



now all I need to do is glue everything together to make the cab

off to bed now.

So this whole thing will be glued together? And you are going to ram these against each other? Why not do some pop rivets? That's cheap and strong?

Because glue is cheaper and stronger. Trust me the Shoo goo I use is stronger than any thing else out there that's readily available to me. Just go look at my other builds. they get the snot beat out of them and hold up just fine.

Need a driver for one?...

True
I use household Goop from Home Depot all the time, stuff can hold together a 1:1 if the surface is clean.

[Metal Masher]

I thought i would give a shot of this, just for realism, it even has rust holes!



More progress

Before I glued the body on I wanted to make a bumper. It needed to be stronger then the panels of course, so I bent up some roof flashing



and glued a mount to it



to attach it to the chassis I made a plate out of brass tubing



It should be very secure and still bend if hit hard enough

here is the bumper in place



then I glued it all up and gave it a quick coat of black









I better shot of the bumper mount



and just like the real ones I has bolts holding the hood shut!



next it's on to the bed

[Trikster]

Man, I wanna come over and play too!

......................... wow that looks awsome considered selling them like a kit mabey make them work with rusty/pede rear/front ends??

[4stAir]

so blake when does the fun go down???

You should record the event with a high speed camera.

Well I've been thinking about making the skins and chassis and letting other people build there own cars. let me get these done first and go from there.

well I was originally planning on running them at this last comp but when it got moved up I didn't have time to finish all of them. I may just slowly build them over the winter and run them in the spring. not sure yet.

I would love to if I could find one that's affordable. there is a lot of stuff I want to record in slo-mo.
