I recently replaced my old helical focuser on my 10 in. Dob. with a new JMI Event Horizon 3 Newtonian single speed focuser. I have always liked the JMI DX3 that came with my 12.5" Dob as it is really smooth operating. But this new JMI EV 3 on my 10 in. Dob seems kind of stiff turning the focus knobs and doesn't really move smooth. Is there anything I can do, short of taking it apart, like putting some lithium lube on it? Or is there just a break-in time on it like a new pair of shoes?
