Fabricating fiberglass body?

Hello all,

I have a tough question. I would like to get a fiberglass body for my go-kart but I wanted a hot rod style and therefore I'd need to have one custom made. Too much money that would be. Well, now I wanna fabricate my own body fiberglass body or plastic or something like that. Does anyone know how I could do that? How much would it cost? Is it possible? Any comments?

Mike

First, get a manual on working with fiberglass. Then decide if you have the ability and money to work with this construction medium. It stinks and itches.

tough problem

This is a tough problem. You will have at least several hundred bucks in materials and one big big mess. In a few words...if you want a one off body you will need to make a mold that will accept layers of glass cloth and resin which will make a shell. You will have to be able to get the shell off the mold. Hopefully the mold release works...if not... welll start over. I make big model airplanes this way as well as special molded parts. I use a variety of materials for molds. Sometimes el cheapo foam bead board works for one off molds and I can use any strong solvent to disolve the foam. Otheres I make a male mold just like what I want. Then I pull off a shell and make a female mold from it. Add a pile of stiffening, shine it up and lay in a bunch of mold release. I then lay up the final product. As you can see you will make the thing at least twice...one male ond one female so you will use a ton of material. This is a gross simplification of the process however. There is a place in Delano Minnesota that makes go kart stuff fairly reasonable. You will have to ckeck the internet or street rod mags. CST and West Systems have the glass and resins as weoll as Aircraft Spruce. None is cheap. Some are unhealthy.

Why not just buy a pre-fab'd streetrod go-kart body? I use this wonderful tool that is free for anyone to use to find things like that.
TOOL
Here is what I came up with:
Aero F/G
Corvette?
I am sure that there are several others out there...remember to use that tool that I let you in on....
Later,

Thanks for all the replies but it seems I'll give up the fiberglass idea.
Weimer, thanks a lot for that tool....WoW!!!!!!!!! It works sooo good! I owe you one! LOL
The problem is I didnt want to spend that much money on a factory fiberglass body and most of them are way too small for my go-kart. I have a 340cc 2cyl engine so the engine alone takes up a lot of space. I thought maybe making my own would be cheaper but I was proven wrong.
I think I'll have to go with plywood.......or maybe sheet metal. I'm still deciding wether I want a cobra, 32 ford or a t-bucket. Any ideas?
Thanks for the input
Mike

You can also make a "plug" out of formica to make your mold off of and what you can do is wherever you have a seem or gap you can fill it with bondo this is how we do our molds on the 16' flat bottom boats we build. after the plug is done wax it about 10 times with mold release wax then spray it with a product called duratec or a tooling gelcoat we use Black so you can see the wax haze up better seems like a lot of work to build 1 body .

Hey 12second,

Can you bend that formica into compound complex curves or are you pretty much using squared off angles for your boats. Do you make a wood frame to attach the formica to?

You can get the thin 1/16 or1/8 inch formica laminate to make your bends you can make a frame out of anything as long as the part that is going against the fiberglass is formica . If the bend is gonna be really tight thats where you could make the radius out of bondo and shape it to your desired shape.
