I would like to replace the rack & pinion focuser on my Orion ST90 with a Crayford unit that I bought a while ago.
The existing r&p unit 'wobbles' around all over the place when focusing, and my efforts to correct this have only been partially successful. I'm 100% sure that the Crayford would resolve the problem and give me much better views through this scope.
However, this means that I need to manufacture a collar or adapter to attach the focuser to the tube. My metal working skills are zero, and I don't think I'm going to find an off the shelf unit that would do the trick.
So, I either have to learn of a simple way that others have used to tackle this task, and that I could do myself, or have the unit made up for me.
I'm wondering if there is anyone in the IIS community who does small jobs like this? I would cheerfully pay for materials and labor to get the job done properly.
Cheers
Chris
