I’m getting ready to move on from the rib-forming phase to the assembling-stuff phase, and am planning to tackle the ailerons first (smallest spar and fewest parts to redo if I screw up). I’ve been looking over my plans and reading through Eric Newton’s manual (and searched this forum), but have three aileron questions:
1. I still need to drill the balance tube holes in the aileron nose ribs. I’m presuming I should do it for all ribs, even though the tube is only in the center section between the hinges. I figure this will allow me to install it after aileron assembly, and also means I can get a long drill bit in there if I need to drill out any lead to balance. Any problems with this logic?
2. Speaking of the balance tube, I’m presuming I can use any aluminum alloy/temper since it is not called out in the plans? I’m planning on getting 2024T3 because, well, why not? The plans just say 3/4†OD and 0.035†wall thickness. I’m not planning to install the tubes until after I cover (years from now), but will probably get the tube so I can dry fit to check tolerances, etc.
3. I can’t find the sheet thickness on the plans for the inboard aileron skin gusset. I may just be missing it, but I don’t see it. It’s the one with the pen pointing to it in the attached picture. Eric’s manual says it’s 0.032†because it’s where the actuation arm goes, but that was a model A. Can anyone confirm/deny that this is 0.032?
Thanks!
