A warning from my experience on the 705 rear spars. There is one rivet per side that is located underneath the angled part shown in the image above. Dont forget them. I cost me one whole work session to drill a dozen long AN470s out, install the two rivets I forgot, and re-rivet the AN470s

Thanks for the heads-up Bill. I did notice that, but I didn't want to drill it until after I remove the doubler bars, which I'll do after I fabricate and drill the F-704H spacers. With your reminder, I'll be less likely to have a senior moment at my next work session!
I know what you mean about drilling out long rivets. Yesterday I riveted in the vertical spacer bars to the F-704 before I riveted on the vertical members, without which the -14 rivet called for in the plans was a perfect fit.  Took me about a half hour to recover. I had to drill off both the factory and shop heads then drill through the rivet with a smaller bit before I could coax the remnants of the shanks out of the holes in the bars. Since -14 is the longest AD426-4 rivet in the kit the shop head came out quite small with the vertical in place. I seem to remember that other builders have run into this and were told that those rivets only hold the bar in position until the bolts can be installed.

Hi Miles, the manual doesn't specifically mention it, but I made mine parallel. It just makes sense to me. I remember shortening the connecting rod a bit until they were parallel.
Have fun building the fuselage. It's the most enjoyable part of the whole thing!

Having visited Miles garage this weekend and looking at his project, I can attest that the craftsmanship looks as good in person as it does in the pictures. Nice work Miles! Thanks again for taking me to the Rosamond Chapter 1000 flyin this weekend and coming down to Bako!

Thanks Bruce. Since some folks are having an issue with the large pushrod length, I've decided to leave it as is until I get the wings mated. The sticks are only 3-1/2 degrees out of parallel, so you have to stand back a ways to be able to see it.

I am already! Due to other commitments couldn't work on it last night and won't be able to tonight, and I'm starting to feel withdrawl...

Thanks for the kind words Bruce. (Only I know where all the warts are!). If mine comes out as well as yours, I'll be happy.

Bulkheads Galore!
Not a bad bit of progress over the weekend:
I think all the metalwork is done on the F-705 seat back bulkhead including edge and hole deburring, but I wasn't in a prepping and priming mood, so I left it as a pile of parts to deal with later. (Oh yeah, I notched the most outboard lap belt anchor flanges to clear a rivet head BEFORE I noticed that rivet is to be countersunk for clearance. Oh well, what's another $12 worth of parts...  )
I ran into an issue on the F-706 rear baggage bulkhead with the F-729 bellcrank rib. The length called out on the plans for the F-729B angle seems to be a tad short. With the minimum 2D edge distance where it attaches to the F-729C on the forward end, there's only about 1.5D on the aft most hole attaching the angle to the rib. I think it's OK, but if I were doing it again, I'd make that angle about 5/32" to 3/16" longer, and radius the ends for the rib if I had to.
Also, I didn't final drill the one rivet hole between the F-729C short spanwise angle and the F-729B longitudinal angle. With all parts of the bulkhead clecoed and clamped, there's still a little relative movement between the two parts. I think I can wait until the bulkhead is stiffened up by clecoing it to the skins later in the process:
One more thing for those who follow: The F-730 reinforcement plate on the F-706 bulkhead has a definite orientation. The corner with no rivet hole goes in the upper left corner (relative to the airplane). I almost drilled it in backwards, but caught the error due to some misaligned holes.
I still have quite a bit of deburring, prep, and prime to do before final assembly of the bulkheads. I think I'll take my time with that, as the next step in the manual is BENDING THE LONGERONS...

Miles,
Beg, borrow or steal the biggest heavy duty vice you can find for bending the longhorns. It makes the job easier for sure.

Thanks for the heads-up David. I have a borrowed copy of George Orndorff's RV-7/9 Fuselage Contstructon video I've watched once, and his method doesn't use a large hammer, but just body weight (and I have an abundance of that  ), to do the bending, and both longerons at the same time to boot. I'm going to go through that video another time or two and give that method a try. If it does come down to the brute force method, I do have several friends with vices much heaver than mine...

I bought the longeron bending dies from a fellow on here, makes that job easy.
