Drilled tailwheel mount: 3.5 hours

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.

 

The laser gadget is handy:

 

All the drill bits used to go from 1/8" to 1/4":
