RE: Ace Extra 230 33% Fiberglass
Top, bottom and side plates are original. Ireplaced the 1/4" thick firewall with new material. Irelieved the ends of the 1/8"material and notched the 1/4" firewall so the pieces would overlap. This moved the firewall 1/4"aft - I'll adjust the lengthby adding spacers to the stand-offs supplied with theengine. F-1 and 2 are the new formers, printed fromscale acad sketches, transfered to the plywood and cut on bandsaw. Note the lower holes in F-2 and thegearplate support slots in F-1 below the epoxy joint - these were done on my mill. Turned out to be a nice rigid structure. SInce Iused original plywood for the basic box, the aluminum angle reinforcement is just a little structuralinsurance- I'll show that later.
Thanks!!
