Stuff like this seems to take me a crazy long time, but I've found that the best way for me to fabricate a really precise part is to start with a rough dimension based on the print and then final size by matching to to assembly. This means lots and lots of walking back and forth between the fuselage and the bad saw or 3 wheel I have on a grinder on the back landing, to keep some at least some of the aluminum dust out of the garage.

At any rate, I made the F-710C Spacer, F-711E Stop/Spacer and F-712D Elevator Stop. The plans don't say anything at all about these at this stage, They just say rivet the back deck. But if you look at drawing 27A the fwd two spacers go under the aft deck and take up the 1/8" gap between the bulkheads and the deck, so they pretty much have to be fabricated and installed as part of that process. I'm going to hold off on installing the F-712D elevator stop until later, because the aft rudder spar gets attached to it as well and I'd like to trial fit all that together to make sure I get it positioned properly.

FYI- for F-712D An old revision of the print shows one of the legs being 1 1/4" wide, but the current rev has both legs being less than an inch. However, they still give you a 1X1 1/2" chunk of angle to make this out of, so you have to rip both sides to a smaller dimension. The print calls for a weird joggle on the face of the horizontal angle, and I debated just making it straight across and skipping that part, like I've seen on other build logs, but then realized that when it's time to rig the elevators, if you need more up travel you can file off that area with a lot less hassle if it's made this way.
