Status: offline 		I've been reading about these for a few days now and decided I want to build one, or at least give it a shot.

I'm looking at going with a Stadium Truck type design. Aluminum pan with a metal rollcage. Going to try to keep the weight down and use a weedeater engine.


What thickness should the Aluminum pan be?


Does anyone have pictures with dimensions of their trucks/cars?

Status: offline 		When I first got to thinking about building one, that was exactly what I was going to do - steel brake line. It's cheap and easy to get.

But then I got to thinking, would it be strong enough? It's hollow inside so that has me a little worried.

If I do go this route, what kind of sheetmetal would you recommend?

Thanks

Status: offline 		That fuel line is stronger than you think once you get all the bracing done it is very strong hollow or not. I can set on my Beretta chassis and it dont move/flex at all and i weight around 180LBS. as far as the sheetmetal you need to look around any home improvement store will have alot of different gauges. I used heating/air ducking sheetmetal it's cheap and easy to work with. a good pair of sisors will cut it with no problems. i got my sisors at Harbour freight,,, if theres one around there...stoneyberk www.quarterscaleberetta.com

Status: offline 		Thanks for the help.

Sorry to keep perstering, but got a few more questions if you don't mind:

What size brake line would recommend for it?

Would a Lincoln 220 welder work for it? Or what do you use?

Thanks

PS: I took a look at your site, awesome job on your builds!

Status: offline 		Ask me all the questions you want..no prob.. I used 1/2'' seamless steel brake line for the main section & 3/8''on the bracing. as far as a welder thats up to you I used J B WELD & 4-40 screws and glued in 4-40 bungs/nuts. that stuff is awesome. once it sets up it is real strong. it worked great for me and i have Built 3 cars that way and never had any problems at all. It can be used on almost any thing..I sanded all the fuel line with 80 Grit sand paper before i cut it to size& used a course round file on the inside of the tubes..stoneyberk

Status: offline 		well if you want to use your welder i would go with 1/2 inch for the main section and then 3/8 on the cage....but i would go with 16 gauge steel tubing.....the brake line is too thin to weld you can braze it but i wouldnt be as afective as the mig......
hers a drawing i did for one of my future builds.

and i used 1/2 inch steel conduit from homedepot and it works great i think i went over board on it...lol b/c i weigh at 297 and it holds me with no prob at all....

heres a pic of it it stands where it is at right now im not done just yet.! its a 1/4 scale petrol rock crawler.

Status: offline 		Boy that would be a close call they both look good to me!! You need to name them [Some Bad Ass Toys For Some Bad Ass Boys] I think They are both a little over 1/4 scale mabye closer to 1/3 scale. But Hey so is my Beretta I still need to stretch the front 4'' on it so that 1/3 scale Blown engine will fit in it with plenty of room to work around. The Headers are going to be Huge tubes around 3/4'' or so. Plus i need to chop the top a tad.
