Reply to: Anyone know what manufacturer's used to fill rudders with?

Message body

[quote=charlescarlis]Hey Scott - no doubt; and, if you need some help vacuum bagging it and finishing in clear, just let me know since I got that down pat.  We just need a good Friday evening to lay up and Saturday to do the hot coats.

I just WANT to try my hand at making a full on, vacuum infusion rudder mold, and will likely either start with the standard Hobie rudder or Prindle rudder, since those seem to be the most useful to friends/acquaintances.

The advantage of molding, is I won't have NEAR the post finish work to do.  All the strength will be in the glass and reinforcements - not derived from the fill material.  That core material referred to above is Coremat Xi.  I did find "foaming epoxy", which looks to be the trick; hard as a rock when cured but can be poured and utilized like urethane foam.  Only, it's a bit heavier and a WHOLE LOT more expensive.  It may all be for nothing, but that and my giant CNC plotter are my "winter projects".  Once I get going, I'll post.[/quote]
