GSO RC8 Focuser side slop.

Has anybody else noticed the side-to-side (azimuth?) slop in the draw tube of the stock Crayford? It is still present on mine even with both upper (lock) and lower (tension) screws done up really tight.

I removed it today and found that there is excessive clearance in the little bottom "guide rail" assembly that the draw tube rides on, and with all tube support concentrated at the rear end, it gives the tube a lot of opportunity to "swivel" around that point, courtesy of that side clearance.

I will disassemble mine tomorrow and see what, if anything, is a practical solution. I would rather not do something that requires drilling holes in the casing, but who knows......

Has anyone else noticed this problem and are there any "quick fixes" that work?

I understand the real "quick fix" is to buy a Moonlight, but I'm a little stubborn.
