sticky 10"dob

[raymo]

My 10"collapsible Skywatcher has always been sticky to move on both axes. I fixed the azimuth axis by fitting a 30cm diameter thrust bearing
which I can adjust with the turntable centre bolt; I have been unable to
come up with a solution for the altitude movement. It is almost impossible to use the scope at more than about 80x. I thought about
fitting four small ball bearings in place of the supposedly Teflon supports.
Has anybody else had this problem? and if so, have they managed to overcome it?
P.S. I have got so peed off, that I've gone back to my old faithful
30 yr. old Celestron C-8.
thanks in advance raymo

My 12" collapsible has been very smooth in RA but had very minor sticky bits in ALT when moving very small amounts. Some silicone spray on the teflon supports and surrounds helped to fix this.
