    Hi Andy. Quick question for you about the TAL 100RS focuser. I had one of the TALs start to play up, and having taken the focuser apart found one of the 4 small bearings has come apart. I have ordered some new ones (after I found the link on an old thread), but is there any other modifications / refurb I can do whilst its apart? It had started to slip a little, so did hear comments referring to roughing up the draw tube surface to aid grip? Thought I would ask an expert having drawn a blank searching on line. Hope all is well!

     

    Regards

      Shims? Mmm. Only thing I can think of is that they came from beneath the curved metal piece that holds the bearings.

      Hi.

       The following link, https://agenaastro.com/optimizing-your-gso-crayford-focuser.html

      whilst not for a Tal focuser, is a good resource for tuning up crayfords. I wouldn't advise roughing up or using a flattening stone on it. Doing so would cut through the hardened anodised outer coating, leaving the softer natural alluminium surface to the elements. I'd only use a flattening stone if the flat had been damaged. I think the link doesn't advise roughing up either?

       Whilst apart, I'd have a look at the internal blackening of the drawtube. If you think it could be better, now would be a good time to give it a coat of ultra flat matt paint. Same goes for the focuser end of the ota. Somewhat more advanced, but if you have access or know someone with a bench drill, it wouldn't be a bad idea to add a second(perhaps even a third) threaded hole(M4?) 120 degrees around from the original thumbscrew. 

      Can't think of anything else at the mo, but I do believe with the new bearings installed, you should notice a vast improvement.

      Cheers, Andy

      Has it hit Londonium yet, or has the tracking gone into limbo? I've had that happen a few times and it's most frustrating :(
