Prep'd & Primed all bulkheads (except F-711) - 9 hours

Managed a huge day today in the garage. A very tedious process to prime that I have. Scuff parts, wash in soapy water, rinse, dry, wax & degrease, MEK, Prime. With setup and take down of the large containers for washing parts it takes a lot of time so its beneficial to prime all at once. Also I am motivated to get this done as I always like to have a full 24 hours dry time minimum to the primer before I assemble.

Since bulkheads F-706 and F-712 where ready to go, I started the priming process for those.

As those parts were drying, I needed to work on the F-710B angle. The fit of the angle wasn't the best for the tabs on the bulkhead where the longerons get installed. The sharp corner on the end of the angle needs to be rounded to allow the bulkhead, tab and angle all to sit flush.



I went to work rounding that corner. However one of the jobs I need to do is to round the top flange of the F-710B angle so it nests nicely inside of the longeron. The best way I believe I can do this is to round it once I have it all installed and can verify perfect fit. So I will hold off on riveting this part until later.

Once I finished rounding the angle for the bulkhead tabs, I moved on to prepping the F-707, F-708 and F-710 parts for priming. Lots of work to break all the edges, deburr and polish all the nooks and crannies. I opened the holes for the rudder cables (Did I ever mention I hate doing those?) and the static lines. Then it was through the long a tedious process of priming....
