Decided to put a gso crayford on my C6, was excited when the focuser arrived, I have ordered the linear rail version this time since i have a ball bearing version for my refractor, but the ball bearing ones have quite a bit of draw tube slop.
I ran into a few problem during and after install.
first, It does not fit correctly, the adapter ring interferes with the stock focuser retaining ring and mounting screws. Well no big deal, I have a lathe, and with that, there is not such thing as "doesn't fit".
clears everything now, good to go? well kind of.
well, after I got that sorted out, then I noticed the focuser got some serious play when you wiggle the wheels.
turns out, there is no support to the shaft on left side of the wheel/shaft. I bought this focuser new from agena astro, so its either assembly error from factory or its a design flaw. if any of you can check to see yours has the same issue and post about it here or link me to a post that would be awesome.
heres a video of the issue.
heres what it look like after I removed the knob, as you can see, there are no support, no bushing, no bearings.
only a plastic spacer and a thrust washer to keep the shaft center.
the existing spacer goes into the bushing and the whole thing fits into the shaft housing.
moved the thrust washer up top between the new bushing and the knob.
and heres the video of after installing the bushing, zero play, still turns as smooth as before. and my telescope is now pretty awesome.
