I'm still confused as to exactly what you want to do.well i dont really know about selling them more about getting introuble for making them
i would be making the railsYour going to use the mold/shape of a WTB seat and affix premade Ti rails to it?
Your welcome to any projects for kicks, but if you want to make money you'd be better off scrounging for the vehicle disc brake rotors.
You sire need more experiance with quality carbon parts. I know of a couple of good carbon bars that take loads of hits, same for a seat with carbon rails (or some other part) I remember weighting 90g weighed and it still lives for a lot of ppl around here. My monkey lite dh took many direct hits with rocks and trees and has some scratches and holds ok after 1.5seasons (though I will chnage it soon due to height).The only two things Carbon the I would ever put on my bike are stem spacers and a seat post.
Carbon and DH don't mix. while I'm sure to catch heat for this from techie guys I know better. Carbon blows hands down. Titanium wins
well im thinking of just useing a seat as a mold, making another mold of both sides and bonding the two pieces of carbon togeatherahh you can use any bag basically, a heavy duty trash bag, but you need a special pump which will suck air as it implies, and you also need some other stuff to absorb the extra resin the vacuum pulls from the part. for just you, i would do it just a hand lay up with minimal resin. also, since this is a seat, it is very small, that will make things harder for you, to get carbon or kevlar or even some heavier fiberglasses to make the contours that the seat probably has. can you post a picture of what you will use for a mold? and female or male mold?
