Ed,

if you go with the classic screw in dowel approach, one trick I learned is to drill out the dowel for the 4-40 screw and then drill out the top of the dowel to pass the head of a cap screw. You can then epoxy the screw and head into the dowel. When you bore out the control surface for the dowel and bond it to the surface, you then also glue both the dowel and cap screw.

Somewhat overkill but I found this easier and nicer to fabricate than screwing in the bolt in the reverse direction and clipping off the head and non threaded portion.

Just another idea.

David.

P.S. Considering the number of Deception kits sold, I'm surprised that those plans never were corrected by bringing the F3 former back to where it should be.
