I triple checked the tailwheel mount alignment (using the the autoleveling laser) and drilled the forward part of the mount to the fuselage.
This took a long time due for several reasons: I had to reach into the fuselage with the drill, the tailwheel mount is made of very hard steel, the alignment of the drill is critical - not much room for error and the hole starts out small and gets opened up to 1/4".
I went through about 7 graduated sizes of drill hits then finished the holes with a reamer.
Everything turned out great.
I also started on working on a taper pin mod to the tailwheel mount.
