Default The hardest part of building an RV-8?

Ok, I'll admit it. I'm starting this thread for my own therapeutic benefit. For all you successful RV-8 builders out there: what was the most difficult part of the build? I'm asking because I've literally spent days trying to get four nuts onto four bolts (I'm talking to you, dreaded landing gear outboard bracket nuts in the Tunnel of Infamy). I really need to know if there are worse horrors that await me. Not to worry, this will not defeat me... but it is a nightmare job to try to do solo, even with a borescope camera and all the extensions and tools (stock and homemade) anyone would ever need.
Thanks for listening... or reading... whatever. MJF

Current status: two forward nuts/washers started; working on the left aft now. Since this photo was taken, the aft bulkhead bolt adjacent to the bracket bolt has been loosened to get clearance. I can get the nut and washer onto the bolt, but despite fabrication of custom tooling, I'm unable to get the threads to catch. Spent many hours trying. Tomorrow I'll have a helper turn the bolt while I hold the nut against the bottom of the bolt; hopefully that will work. Did I mention the fuselage is upside down? It's upside down, all right. That might explain any confusion between left and right; the view is looking up from the bottom. (photos courtesy of borescope cam)

It is the same thing for all the models, convincing the wife it is OK to spend your time and money on!

Martin, do yourself a big favor and replace or shorten the AN3's in the vicinity of the clamp bolts. Your goal is the "one full thread showing" minimum length. The extra four or five threads sticking out just gets in the way when working with the clamp bolts.

That said, I see one on each side which appears too short.

You modified the gear towers for access, or are you working through the standard round holes?

Yep! I see several short bolts. Must have a minimum of one full thread beyond the locknut.

I had an inspector and many other folks try to tell me that you need at least 3 threads showing. I promptly show them the AC 43.13, Par 7-37, which reads; "All bolt installations which involve self-locking or plain nuts should have a least one thread of the bolt protruding through the nut."

I have had to remove , temporary, the bolts that are interfering with your missing nuts

Default short bolts

Those 'bolts' you see without threads showing are #8 screws. I left the washers off to get enough showing but the callout is correct to have clearance with the other bolts. The gear is a pain but doable. I just sat the washers and nuts on the bolts using long reach stick and tape to hold them turned from below. May have to grind socket a bit to get a good fit.

They still need to have a full thread beyond the nut.

Accepted standard is one to three threads showing. Those bolts are too short.
