[TowerTalk] Glen Martin Hazer roller bearings

[N4IJ]

I am looking for ideas for homebrew roller bearings, since there do not
seem to be any available with GM not selling Hazers any longer. Mine seems
to hang on R25 Z braces in a couple of spots.  Not hanging on any tower
bolts.  Anyway - any ideas?  If I could climb I never would have considered
a Hazer. Without antenna parties in the COVID era, I put it up myself. I
did put a heavy duty pulley on it with heavier stainless cable.   It will
never fall for sure.

Anyway - ideas?
