Styrene question

[simdel1]

a method i've seen used quite a lot is a wood base (plywood generally) with cut polystyrene glued on to make the rough shape, then the whole lot is covered in plaster and the final shape is defined. sand smooth then take your fibre glass mould off that.

hope that helps

Polystyrene melts buddy. The epoxy/resin becomes chemically hot thus melting it and then the fiberglass falls in. You need to use polyurethane foam.

So are we talking about 1:1 or 1:24?

1:1 and if you read my post i said plaster NOT putty

its well known process in kit car circles (no, not plastic kits, i mean like kit cars, like becks, caterhams etc)...

Hey guys I know this is a little off topic but: At my hobby shop they have the stiff styrene sheets and the floppy ones. Which one would be better for body kits?

Look at the thickness of them. It should say at the top. I prefer .020 and .030 thicknesses.

That sounds big job, wood, plaster, you cant make good lines with that.

How big are these sheets guys, that styrene stuff? and are they stong? i can use that and to make it stronger i just put coat of fibreglass from inside and that should be stable for sanding.

I found out new shit used for bodykits.. i dpont know what is it called and where to buy it..

Its paper, comes in rolles, 1m high and it has some wire inside so you can bend the paper and make any shape you want, there is special tape used for joint once you have the shape you aplly some paint on top which disolwes in that paper and once its dry its all one big plastic, and hard, easy to sand this sounds great idea, the guy told me he has seen that in body shop in sydney and its great product, he said its very expensive but usefull.

Thanks for help guys

Styrene comes in sheets as big a 20x12

styrene..
that's the stuff they use for vacuum forming right?
does that mean if i make a 1:24 buck of a car form, with careful planning and masking out, i can make my own little body panels out of the stuff?

[supermod04]

if your trying to make a scale body kit for say a 1/24 model. then you would be best to start off with a styrene base. try a .030 thickness. and then glue it on. use the styrene for the basic structure. then putty and sand

They use Lexan (polycarbonate) for vacuum forming.

[drunken monkey]

ok...
i just know it as 'the plastic sheet for the vacuum form machine' in the workshop....

it's just that it cuts in a very similar way to the stuff i got from the model shop.

i guess there's nothing stopping me from trying to make my own little body panels anyway.
the dichlorolmethane seems to be able to bond almost anything plastic...

Hmm they do a procsess of injection molding to make model bodys and parts. They shot hot styrene into a metal mold. That is about it.

[geofroley]

Do you need to put putty over styrene to paint it?

No you but primer over the body parts to paint. For little things i just paint the pieces.
