Hi folks,

I have had my 12" LX-200 classic for about four years. I bought it used and
it was about a year old at that time. It has given me very good service
doing scripted photometry, mostly of asteroids but of variable stars too. I
have run into my first real mechanical problem and I would appreciate some
advice.

A couple of weeks ago I was taking flats near zenith with a light box when
the whole thing tumped forward. The clutch was as tight as I can turn it
when it happened. Since then I have had problems with the dec system. The
dec worm turns the worm wheel but the clutch does not hold well and so I get
a good bit of slippage. My first thought was to get the Petersen kit to
tighten up the clutch but he doesn't sell them for the classic anymore. I
have read through a bunch of stuff on the MAPUG archive and found info on
tweaking worm/worm wheel contact and installation of ball bearings but
nothing about improving the clutch tightness. I'd also like to understand
why the system has so much slippage now when it did not before. I want to
make sure I understand what the actual problem is before I try to fix
something.

Any thoughts would be much appreciated.

Clearest skies,
