RV-10 Main Spar (section 13) questions
Hey VAF!, it's good to be on here again. I spent two years away from the build for various reasons, and now it's time to get back to it. I've got four questions for all you smarter builders out there:
1) When should I be looking at building the wing stand? I currently have two benches end-to-end that support the main spars, but I know it's a matter of time before the spars won't fit on a flat table surface at the same time. When did you transfer from the table to building on the stand? I have limited space in the one-car garage, otherwise, I'd have built it yesterday
2) The wing plans section 13 don't call for deburring the holes anywhere in there (referring to the opposite side of the machine countersinking that is done primarily on the flanges of the spars). Obviously, to me at least, this is part of the graduating level of proficiency as builders progress. Stupid question, but did you all deburr the main spar holes? Common sense tells me "of course", but there's a little part of me that wonders if that beautiful anodized finish should be left alone.
3) Similar to above, page 13-3(?-don't have plans in front of me) step 8 calls for spot priming the countersunk areas from steps 5 and 7. These are the screw attach points, and priming makes sense here. What about the other hundreds of countersunk places on the main spar where rivets attach? No priming there? What did you do?
4) p. 13-4 step 2: countersinking the upper- and lower- most holes for the nutplate attach rivet holes, my countersink collar doesn't fit. Did you manually countersink there with the bit and no collar for precision depth? That's my plan, unless someone can recommend a different option I'm not thinking about.
I will say that I noticed a new section 5 was released during the time I was away, so I will be sure to read that again. Sorry to bother you all with the mundane, but I appreciate the help! n Thanks!
