Good to go.

Had my bi-ennial medical today.  The FAA has determined I am medically qualified to aviate for another two years.

Just a few details tonight, all on the right hand fuselage lower longeron.  There were a few details that had to be drilled and until the disassembly there was no access.  First was the bumper doubler.

The dark piece is the one for the left hand side, I just laid it out for show.  This piece is inside the longeron and has been backdrilled as necessary.

Next is the rudder pedal doubler that goes on the side at the front of this piece.  I used a step drill for this 3/8 inch hole.


The passenger gets the same thing.  I put the step drill bit in this photo in case you don't know what they are.


The brass colored Christmas tree bit is a step drill.  They work very smoothly on large holes in thin sheet.  They act more as a boring tool than a twist drill.  There is no pulling at the sheet and it results in a very round hole.  Unfortunately they are not made for number sizes, just fractional.  Maybe I should start making some for other home builders.  Bleriot is in the background on this photo.
