This was the technique I used on the advice of - oh bugger I can't remember.
A strong inspection lamp above will show you where the rib is.

Andrew,
There was quite a thread on this topic some time back. I posted once or
twice on how to do the mod using tape and a bright lamp - if you search on
me you should find the thread and can get the rest from there.
Kind regards,
Jeremy

Thanks for that explanation. Here is a technique that I think might work
better (assuming I understand it correctly). My wingtips have cutouts for
the installation of nav lights at the leading egde. That gives me access to
the ribs in front of the spar. The rib we are looking for is the second one
---From the tip. The first one (and presumably all) have small holes for
pressure equalization. I can push a long wooden dowel through the first rib
until it hits the second rib, and get an exact measure of its distance from
the tip. Then I transfer that distance (minus 0.5" for the flange) along the
leading edge and drill the hole. Does that sound right?
I could not find Neville's posting in the archives on using a light bulb to
locate the distance. If anyone can send me a reference, I would appreciate
it. Thanks.
