Still working on the firewall. Made a 3/64" plywood shim ring to glue to the back of the temp spinner back plate to set the proper clearance. then was able to finalize the firewall location. Also made some 3/8" thick CF shims to install between the stand offs and the firewall to allow more room/distance in the event I go with a larger motor and to make linkage connections a bit easier. Once the motor was re secured I installed the firewall shims to the standoffs and secured them with the bolts. Next I installed small round earth magnets on each bolt heads and slid the firewall tight against the magnets. Using a small stack of the same magnets I was able to located the exact location for the bolt holes. Worked out pretty good. after drilling the holes the firewall get re mounted to the motor for initial epoxy to the fuse. I plan on using a combination of CF and FG to epoxy glass it to the fuse. I will also be cutting a skeleton-ized doubler for the back of the firewall
to give more strength to the bonding surface.
