: Looking to make a composite (carbon/fiberglass) seat for my kayak
: and was wondering what methods you would suggest to get the
: right fit.

: One thing that comes to mind is to make a mould taken from my own
: behind sitting into something that would retain my butt's shape
: after I get up (and hopefully won't hurt me in the process -;) )

: I saw this
: http://www.kayakforum.com/cgi-bin/Building/Archive50.pl/noframes/read/53500.
: Also remember reading about using ready-made plaster sheets that
: can be formed as desired, but lost the link and can't seem to
: find it - can anyone refresh my memory?

: Basically, looking to make a slippery lightweight composite seat
: with a raised back just enough to keep me in it when it gets a
: bit bumpy. The seat will be mounted to replace a factory seat in
: my boat. I have a foam seat already and that works fine but I
: want something that would allow me to move about more freely,
: sort of like in racing kayaks and surf skis.

: Suggestions on shaping it and construction hints will be most
: appreciated. For instance, what would be the overall thickness I
: would want to get to to ensure it won't crack too easy, etc. I
: will probably be able to do a rudimentary vacuum bag with my
: food saver so looking to make that in one shot if possible and
: to make it lighter and stronger.

: Thanks!

Oh yeah btw, thickness. Suspect it'll be much like a coaming for strength issues. Likely want the layup around 1/8" thick depends almost entirely on what fabric you're using, obviously in CF it could be much lighter.
