Let's install the fuse doublers.

Test fit the 3 forward doublers and prep sand and fit into the fuse sides. Test fit the rear doublers for the Stab tube and forward stab adjuster. On the stab adjuster doubler mark and drill a 1/8" hole for the adjuster wire. I use the stab root plywood plate to position the stab adjuster doubler. Note here that the hole through the stab root plate is offset and the hole is above center. Cut and fit the 1/8 balsa vertical grain doublers that extend form f2 to the firewall, leave a 1/8 gap at the bottom for the flooring and fit it to the rear of the firewall.

Once everything is fitted I mix a small batch of West Systems epoxy and spread a thin layer with an epoxy brush, I usually cut the bristles of the epoxy brush down to about 1/4", you will be able to spread a neater thinner coat of epoxy that way. I actually position the stab adj. doubler with the wire and tube in position as I lay it in position with epoxy. Work you way up the fuse epoxying the forward doublers in position, use the formers again here as positioning guides to get a tight fit. Do both sides and lay both sides up together with weight. I cut small planks of MDF or partical board and stack my weights across both sides. Again use all the weight you have on hand, also wipe away excess epoxy. Let this cure overnight.
