StarLane,
For the best results, go the 'Ebony Star' route.
You have the 'milk bottle washers' fitted correctly if there's just a little play in between the 2 base boards, (FWIW. I have approx.10 mm play & it positively rattles when shaken/moved), so do not tighten the centre bolt too much.
The t'scope should move O.K. with no lubricant at all applied, so remove any traces with Metho., & try to do the 'mechanical' set-up first.
(I run mine completely dry, but I do have Ebony Star fitted with the original Teflon pads).
That way, it will not collect 'crap'. Just dismantle 'bout once/year n dry clean.
HTH..
