The original owner of my tail kit did some final drilling of the holes common to the horizontal stab spars and their doublers. The plans say to be sure to drill these holes perpendicular to the web. So I’d like to check the accuracy of these holes.
My idea is to cleco the parts together and insert the blank end of the appropriate size drill bit into the holes then use my machinist square to check for perpendicular. Has anyone tried this or know of a different method?
