I am at the step where I am to drill the 11/32 hole in the rear spar doubler inboard…. There is a 3/32 hole already at the location. It nests with the other doubler that already has a 11/32 hole drilled at the location.
Is there a technique to best assure that a 11/32 hole drilled into a 3/32 pilot goes on center? I have a drill press and not running it too fast.
The manual doesn't say to do it but should I drill the piloted piece mated to the already drilled piece? Will the part with the existing hole help line things up?
And finally, later after I assemble the rear spar to doublers prior to mounting on the wing that hole gets reamed out to 3/8 with a reamer. My drill press is high - I'm going to have to support the spar somehow at the right height to get it down on the drill press table - it sure is a long piece!
If anyone got bit on this step somehow I'd like to not reinvent the wheel…….
