[rebel-builders] Rebel -Tail-spring bulkhead - FUS-30

Hi Ron !
If I recall - what you can't see behind that "X" pattern, is
that it is fastening pieces of wing stringer on the inside,
for extra stiffness .... or you could use angle or channel...
I'm with Wayne - a bunch of extra rivets, along with
slathers of epoxy primer in between layers, is a "Good Thing"(tm)
to really tie these 2 FUS-30's together !
Certainly, extra rivets around the cut-out holes are
important - the second layer will be effective as a doubler,
IF it is rivetted in the same pattern.

holesWayne, as I described, the elevator tube holes were cut on the
underlying original fuse skin first, with the tubes & elevators in
place, so they should be fine.
I copied the rivet pattern from the picture of this design of FUS-30
doubler in the archives that Bob P. was recommending, particularly the
new "X" rivet pattern in the aft portion, and tying into several rivets
of FUS-89. It's quite solidly tied to everything, but as you suggest,
perhaps it could use even more.

surfaces(they will probably will need some minor opening..they always do) remember
to go back and drill around the oval cutout and rivet the two Fus-30's
together there. If it was me I'd have a lot more rivets in the flat
of that doubling Fus-30 as well, to really make them work as one unit.
