Magnus,
The brass worm is really only needed on the RA, but having it on both axes gives you a spare, if ever needed. Getting the adjustment correct for the stock system goes a long way for performance. That means having both bearing blocks square to each other and having enough backlash for no binding and no lateral movement of the worm.?
What I did years ago before the brass worm was available was use a cordless drill to drive the worm for 15 minutes in each direct with the finest lapping fluid I could find. Did a thorough clean up and readjustment. Was able to cut the backlash needed in half.?
Don?

Hi!
There has been tons of discussions on worm gears, but as I see more about OPW vs Ovision. My G11 apparently has the older stainless steel worms, so an upgrade is imminent. However, at least at Telescope Express, the high precision worm is sold, without the blocks and all:
So the same 3-piece system I have now, but a better worm. Now, is that what I should do, or should I pay sbustantially more and get the OPW-11? How much do I gain from the one-piece device?
Or is the high precision worm only useable with the one-piece system? It is sold both with and without the worm, which confuses me.. As on Losmandy's page:
http://www.losmandy.com/access.htmlAnd how does these upgrades compare to the belville washer solution? Or is that just for DEC and the high precision worm just for RA.....?
