    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

      I had some issues with my Tal 100RS focuser drawtube where it wasn't running true whilst racking in and out.

      Turns out there was a discrepancy on the flat of the draw tube,  one end measured 54.60mm, the other end was 55.04mm, that was enough for the focuser to slip when fully racked out.

      I flattened it out with a carborundum stone and removed the discrepancy and improved the grip (took some time though and constant checks with a  vernier gauge!!)

      Got all the above info off SGL member Moriniboy who had the same problem, he sent me some really good photos as well, I would contact him.

      PS No probs with the Tal focuser since.

      Thanks Gents. one last question. Where do the shims go? Two came out when the draw tube was removed, but cannot see an obvious place for them to reside. Any assistance greatly appreciated.

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