-Mounted the tailwheel mount to the F811 bulkhead with shimes.
-Cleco'd the F812 to the F828 aft bottom skin (short section at the very end)
-Rivted F812 to the F828. Rather than using a 25lb shot bag laying in the F828 skin as the plan describe, I clamped the F812 to the bench. The fwd row of rivets I shot and the aft row I could flip the assembly upside down, clamp and then use my hand squeezer. Came out good.
-Cleco'd F811 to the F828 in preparation for riveting.
Tailwheel mount bolted to the F811 bulkhead
Note here I have the F812 bulkhead clamped to the bench - that worked great for shooting the rivets.
Here it is flipped over and I'm squeezing the aft row of rivets with good access.
