Brief Description: Fuselage - Firewall engine mount holes
In order to eventually build a rotisserie jig, I started examining how I could install it on the firewall. First order of the day was to drill out the pilot holes found in the metal support.I drilled those undersize to dia 1/4", instead of the final dimension for an AN6 bolt.
While I had the firewall in my hand, I took the time to look at potential solution to add skin damping to it. Took some dimension and annoted drawings to design parts later.
