Some focuser details:
The silver slotted screws on top of the focuser can be tightened slightly if there is any drawtube slop.
There's a tension adjustment grub screw on the pinion assembly, although I didn't find that to be very effective.
If you need to carry heavier loads the dual focus knobs can be removed by loosening the grub screw holding it to the shaft and the nearby grub screws on the black pinion block - then the slotted brass nut can be tightened slightly to increase pressure on the microfocuser bearing.
In the last photo (detached pinion assembly) you can see a cross hatched area on the shaft which the focus lock bears against; on the other side you can see a white nylon block which the tension adjustment grub screw pushes against the shaft.
It's not a feathertouch but it is quite a decent focuser.
