First I cut all my sleeves to length with a small tube cutter. Then I use a reloadloading deburring tool to taper the back end(makes removing from targets easier)..  After I finish all the sleeves, I glue in the inserts.  Once that is done I apply 24 hr epoxy to the front end of the outside of the shaft, and slowly work the sleeve over the glue until its flush with the front end of the shaft.  The sleeve will push any leftover glue towards the nock end of the shaft. I finish by removing the excess glue, but I leave a small bead that trims the back end of the sleeve.

how long r the sleeves and the size of the aluminum arrow you used for the tube?

Mines are 1.5" and I use 1916 for the .500 spine axis

I use  2020's for my wife's 500's and 2018's for my 340's.

I love them.I shoot everything with MFX 500s and have yet to break one.
