No32 Mk3 Thread question.

[Roger Payne]

Actually, I intend to spin the tube in my Myford as I have a few scopes, including at least one Mk3 where the ocular end is torn, corroded away or otherwise severely damaged & will need replacing by grafting a No42 or 53 ocular end in place. That plug is a fairly tight fit into objective end of the scope tube, & I have turned another one for the ocular end (complete with cone) so I can spin the tube about centres to turn off the damaged ocular end & step the tube so I can then silver solder the new replacement end in place.

But you make an excellent point. Before now I have dolleyed out a nasty dent only to drop the scope tube & put it back in! I now tend to use redundant No42 ocular lens retaining rings when I have a scope stripped down, as this does offer some protection from bumps, the retaining ring taking the knock rather than the end of the tube itself.
