[ATMoB-discuss] Telescope Tube Rings

[BDM]

Google "Ken Dauzat"-- he used to make them, maybe still does.   Try 
to measure your circumference as accurately as possible.

>I have an odd-sized OTA - which I bought from the club several years ago
>- for which I am in search of tube rings to attach to the dovetail
>plate/mount.  The tube is a sonotube (or something like it) and has an
>outside diameter of approx 195mm and so falls between the standard sizes
>on the market (i.e. Orion has 184mm and 235mm rings but nothing in
>between - I bought the 184mm rings thinking they may have enough give to
>work, but I can't make them quite fit, not sure if they could be
>stretched like an undersized wedding ring).  The tube also is fitted
>with fairly wide metal flanges at each end, so the rings would have to
>be hinged to slip around the body rather than over the ends.

>Does anybody have something that might work for this tube, the ability

>(relatively inexpensive) tube rings?
