Craigslist.Where did you find a used arrow saw? And what kind of glue are you using to be able to quickly and easily remove and replace inserts during the cut down process?
I do not remove the inserts. I glue the HIT inserts as the manufacturer describes how and leave them. When I need to cut down an arrow, I take the nock off, and cut it down, square, then put the nock back on.
