I have the need to put two holes in my fuselage skin. To be specific, the F-820-L-1 on an RV-8.
The bolt for the holes will be an AN509-8R10, which has a 100 degree countersunk head. So I will use a #19 drill for the hole, and a #8 die for the dimple.
My problem is that the skin is installed, so I can't use my DRDT-2 to do the dimple. Further, I can't think of any way to hold the female half of the die to back up the skin.
Does anyone here know of a way to dimple a hole in-place on a skin like this?
