I hope this is in the right place... There are two questions here.
I've got my HS all clecoed together and need to match-drill the ribs and spars. In the places where there is both a main rib and nose rib, I don't have clearance to drill through the nose rib, the spar and the main rib all at once. I need to pull the nose rib off, drill the main rib to the spar, then drill the nose rib to the spar in a second step. The issue I see is that I risk 'wallowing out' the hole in the spar by running thorugh it twice. What is the correct way to do this? A right-angle attachment won't give me the clearance either, and a long drill bit will only help me on one hole per rib (there are three).
Second question...
The gentleman I bought my kit from has already alodined and primed these parts - before match drilling, countersinking or dimpling. Would it be advisable, after match drilling and countersinking the holes on the spar flanges, to alodine and prime the newly exposed bare aluminum in the holes - or is this overkill?
Thanks!
