Drilled the cotter pin holes on the right main axle. There's two tricky parts to this: knowing when the axle nut is properly tightened, and creatively clamping the gear leg in place to drill the holes after they're marked. I hope the first part is right, but as long as the wheel is all the way on, then a good solid hand tight should be OK. I used a crescent wrench to tighten the nut down to make sure the wheel was on properly. Then loosed it up and hand tightened.
Didn't take any pictures, but there's another wheel to do.
Also primed my aft fuselage clamp points. They're ready to rivet now.
