Adam,
There certainly is no problem using wood as a traveller support on
your boat. The only problem I see is the fact that it needs to be
raised 10" This would require quite a bit of wood and be really
bulky. At the end of the day it is far more practical to have one
fabricated out of SS or aluminum. There are all kinds of pre-fab
traveller supports out there. Harken, Antal, Schaffer etc. all make
them.
If you do decide to go with wood, I would agree that teak would be a
nice choice. One advantage here is that Teak can be left unfinished
if desired and not rot or deteriorate. Many people like to oil thier
teak for some reason, but this is not the best Idea, both for
protecting the wood, or for making maitenance easier. Varnished teak
does look fabulous, but it is not the easiest wood to varnish and
maintain in that sense. Lord knows I have acres of varnished teak on
my boat, and while it does look great, it does keep me up at night
sometimes worrying about it.
Alternatives to teak could be Mahogany, Iroko or Fir. As far as
Construction goes, I would laminate 1/2" or 3/4" strips of wood to the
desired thickness, then shape to suit. Epoxy would be my glue of
choice here, however you could go with resorcinol if you wished. If
the track follows a camber, then just laminate the support on a jig.
Make sure you put slightly more camber than is needed, because the
wood will inevitably spring back a little bit. Again though, I would
think about a pre-fab or custom metal riser. Let me know if you need
anymore help
