Scratchbuilding seats

Any way to scratchbuild seats?
The only efficient way i can think of, with minimum sanding on the concave part, is to use 1-hour-old-epoxy and put it on a wooden mold. Is there any other, more labour efficient way?
Please help, as i don't think there's any manufacturer making 1:35 racing seats.:(

No reply????????
Anyway i had just embarked on scratchbuilding the seats just like the way i mentioned. The epoxy is in the curing process now. The concave (inside) surface of the seat is smooth, needing only a bit of filler and sanding after curing.

The only other option I would look at is to either build a mold, or cut the seat from a soft wood, such as balsa.

Now, the balsa option probably doesn't sound too exciting, but what you could do is cut it as you want it to look, and then either get a latex mold that you can pour other seats (not that useful unless you want the same seat for many cars), or you could varnish the seat, which will give it some good strength, and then sand it (a good few layers of varnish). This will then also give you a good base to paint onto.

Other options would be a plasticard base, with the basic shape, which you then build up with your epoxy. Similar to what you were talking about yourself, however, your basic shape is simpler to start from.

Good luck!

I had considered what u mentioned, but then those methods would involve a lot of sanding on the concave side, which is harder to sand and shape.
In my method, the epoxy is put on a positive wooden mould (convex). Shaping a convex surface is easier than shaping a concave surface.

Hey guys, my scratchbuilt seat is almost done, very satisfied with the finish, considering this is my first time. :D
