As an update.
I think
I have got it figured. Dec axis does not spin when clutch is not engaged which was one problem solved. Just had to really thin the coating in the housing down. like a film more so than anything.
And I seem to have eliminated that knock and not have any point bind on the worm drive.
So at this point everything is at it should be I believe. One last test is take it out and do some calibrating with PHD2 and see if I fixed my dec backlash issue for certain...
Will report back for further help If its not fixed
