I've been picking at the project a few hours per day this last week, the tailwheel bracket mods on the fuselage are now complete, today I countersunk 2 holes in the bracket to allow clearance for the rudder cables to pass, I match drilled the required holes in the vertical stab spar for the extra rivnuts then started to de-construct the stab so as to install the larger rivnuts. I'll need to replace the 3.2mm rivets that I have removed from it with 4.0mm as some of the holes have elongated a little.
