those pesky nylon rollers Synta fitted on their dobs are prone to...crummy performance


time to change them.


First get 8 bearings, bolts and washers


(70mm/8mm bolt plus washers and 22mm diam. bearing)



The old setup...even tried milkwashers, waxes and cd's..




Insert new bolts, need to drill out the holes a bit (10mmdrillbit).

First set of washers between the board and the bearings.




fits perfectly...and the Alt. action is much smoother..

yes..you mean the skywatcher patented tensioning system?.. :)


that system is not so goo, as they only installed it on the tensioner situated below

the focuser.


the opposite tensioner I modded a bit by adding a spring washer and a little floor felt pad.

Nice simple mod, I wonder if Skywatcher use a slightly better product (cant believe I just said) as mine is perfectly smooth even with loads and loads of weight on it.


Nicely done though.
