Flap cross tube marking tool

I made a ring to help me mark the flap cross tube when trimming length.
Worked out well.
It ended up I only had to trim one side, I think it was the starboard side that needed trimming.
Lefty-righty play after trimming perhaps a little less than 1/16" (.0625").
May give a little bit more before bonding in outer bearings, but only after I can cycle gear-flaps and study.
