Have a new RA worm on order because I noticed a nick right in the center of the worm that was causing a slight binding when meshed.
Under a magnifying glass I used 2500 grit sandpaper to fix a bulge caused by it but it's still noticeable.?
Then I looked through the magnifying glass and saw it was a little rough, along with the whole worm.
Took some ultra fine automotive final mirror polish on a buffing wheel and polished the worm all around for a few seconds.
Will replace that repaired worm with the new one when it comes and check the results.
The nick in the worm seems to be guided out by PEC.
I'm wondering if polishing the worm had any affect in getting the results I'm seeing?
David,
Buffing the worm sounds like an really interesting idea. Also, I've found that nicks are so easily created just installing the worm. Brass is so soft. I'm at about 0.65 arcsec without PEC. I too know I can do better, Those little Ra wonderings in your tracking curve, what do you attribute them too?
