dob mount movement ..

[rory]

ive used the skywatcher 200 skyliner for about three sessions now. very happy with the views and the scope in general. the mount is although perfectly workable , noticably slightly stiffin both directions. as its second hand i noticed two lead weights attached to the bottom of the primary,i assume to balance.question is is there a proper way to set balance ?

would i loosen the handles and it should balance like a set of scales ?

tips welcome please. turning the mount also a little stiff, only a little, you know when you push and one second it doesnt move then very slightly applying a little more force it goes a tad to far and have to bring her back. some of this is probably because im new to the " nudge system"

quickest, easiest, cheapest thing to do is to, undo the centre bolt, split the base, clean the bottom, wipe the 3 teflon slides clean, use pledge / turtle wax on the underside of the top part that runs on the slides ... have a breather ! cut some plastic milk bottles to make a few washers to go over the center bolt to lift the weight very slightly off the teflon slides (experiment 3 to 4 seems about right)

Put it back together .

Second that !

always reminds me of the boiling hot summer when i was a kid, listening to Bob Willis thundering in at a pace of knots

okay all i did was cut up a milk carton and made two washers,although one was enough in the end. i placed it on along with the original washer and hey presto,its done. i found by just adjusting the tightness of the centre bolt i could get the stiction just as required. who'd have thought a piece of plastic milk carton could solve such an issue. cheers for the tip .

Glad it worked for you
