The Nov 15, 2017 YouTube Losmandy video "OPW Adjustment" seems to show how easy it is to adjust the One Piece Worm (OPW).
I'm tempted to try it sometime, when/if it needs adjustment, and just to better understand my mount.
The video begins with the motor removed, but the video doesn't show how to remove the motor assembly.
How difficult is removing the motors? Is it as simple? Are there things to watch out for? Any gotcha's or hints/tips for removing the motor.
Why would you remove the motors for adjusting the backlash ? In order to get a good adjustment in both axis you need to move the axis and test if there is some binding or not ...
If nothing has changed the bore holding the left ball bearing has nearly no play and the bore on the right has enough play to get the worm onto the wormgear in a good position.
If you have the Gemini 1 or 2 system then it will tell you when it is binding as you will get a stall message.
Removing the motors and then attaching them again makes the whole process far to complicated ...
You have to slew the RA axis in 180 degrees to find any binding and the DEC axis more or less nearly 350 degrees.
If you do not that you will never find the best adjustment.
