I couldn’t resist going to the shop for a little pre-turkey fiberglassing.
These are the new rib end caps. We’re fiberglassing the channel around the perimeter. This will make a stiffer backing for the rubber seal. One cap will get high and low volume valves and a pressure gauge. Both will get a smaller foam disk glued to it for stiffness.
Any bets for 3 psi on Saturday anyone?
