Next I install the tail wheel.

Drill the appropriate size hole, test fit the nylon threaded bolt. Then cut the head off the nylon bolt.

It will obviously secure to the rudder later on.
I glued in the nylon bolt recessed a little. You want to keep the wheel collar off the fuse, but so that the aluminum tail wheel assembly holder doesn't have any friction when you turn the tail wheel. It should move freely as to not bind when moving the rudder.
