Making a roll cage/chassis

Im trying to first make a metal body for my mrc. It may also become a chassis depending on how much weight it adds. I like the tube chassis look like the lexan body has. Im also going to put in sheet metal panels when finished. Im concerned ab

out the weight and how much it will change the COG. Anyways im almost finished with the tubing but I ran out. So far only $3 total. Its an exact match except for the extended roll cage. Its very easy to make I just hold it up to the body and cut out the parts.
Any suggestions?



Set it on the truck, I think it looks cool without body panels.

Looks good. So what are you making it from, 3/16 brake line brazed? or solid rod welded?

I found some solid rod at the hobby store, 5/32 music wire is what its labeled. didn't make it to an auto store so I bought this. So far it weighs 6 oz, lexan body is 1.10 oz Im using a mig welder, a crappy one.

That is looking really nice, specially for your first time having a go at making it. Personally would turn it into a chassis if you can to help offset the added weight of the tube body.

Well I finished, but I failed. Spent all day building it, with a splitting headache. Tried my best to make a chassis, but was to hard to line everything up. Also tried as many ways as I could think of to just mount the body and came up with using the plastic posts. I don't have many spare parts to try a different mounting option. Got it mounted up and the servo hits when moving the suspension. WHen it was in mock up the left side wasnt on so I never saw it would hit. I now see the front bends in about 1/2 inch more then the lexan body. My head is still killing me so im just going to give up. Maybe another day I will look at it more to see if I can salvage it and make a chassis. I may make cardboard templates for the 3 link mount and engine mounts. Thankfully I didn't ruin any stock parts and it can still be driven.

If at first you don't succeed try try again, LOL!!!! and a good first attempt it was, I'm sure with a little trial and error you will get one to work.
