I currently have a Zhumell 2" single speed Crayford focuser on my 10" dob. It is an upgrade from the one I originally had on the 10" F/4.7 Skywatcher one that was originally on there.
I don't know if this has anything to do with how the focuser works, but mine is mounted sideways so that the focusing knobs are in a different orientation than normal. See my pic attached:
I am now using heavier eyepieces, (a 14mm ES 100 and a 9mm ES 100), and I find that the only way I can use the focuser is if I have the tension knob fairly tight so the focuser won't "slip". The only thing about this is that the focusing becomes somewhat "stiff" and no longer has any smooth action.
Is there anything I can do to fix this? or am I looking at getting yet another focuser which is better?
PS: I was thinking of getting a 2" GSO Linear Bearing focuser to replace it.....Is that one a lot better?
...Or do I just need this below?
