Plossl lenses - tight fit?

[Moonlune]

I bought a set of Plossl lenses and a Barlow for my Old Bushnell Voyager reflector 900mm FL and the Plossl lenses were more of an interference fit than a sliding fit into the focussing tube.  I guessed that the plastic tube would be the easiest to work on, so eased it with a bit of fine wet and dry rubbing paper until a sliding fit was achieved,  The Plossl lenses are much better than the original poor quality lenses that came with it (not sure if they were original or not).  The scope is very old but gave me a good shot of a star, once set up tonight.  The material taken out was no more than a few thou' so hopefully no ill effects but easier lens changing!  Cloud stopped play!
