I am not the original owner so I don't know if I am missing some parts. I can tighten the bolt in the swivel after adjusting the 1 to 4 scale as far as I can and it moves easily when in use. Today I took it apart to see if I could make a friction washer or something and found that will not work as the fit is so tight I had to struggle to pull it apart with the bolt removed. I did find that there were hollows on the inside of the arm side and I wonder if there were rubber inserts that fit in the hollows to make a no slide compression pieces to hold the setting. Can anybody check theirs and let me know if my guess is correct? Ideas?
I had one of these jigs and I'm pretty sure there was a rubber washer in there. I'll look to see if I still have it to confirm.
