Thread: shimming scope rings confusion

Interesting development. I put two shims (0.1mm thick each) from the V can on the front and put scope back in place and screwed rings together. Farkin awful! The magnification was all but impossible to turn, meaning tube was distorted. Took it apart, removed one shim and stuck it back together. Better but not I'm still not comfortable. So the plan is now I'll araldite one shim on the rear and two on the front, once the glue's dry I'll run a reamer through to create the angle hopefully taking the pressure off the scope tube. If the araldite lets go after the scope's screwed down it doesn't matter. It's only needed to keep the shims in place during reaming and locking down. Main lesson learned: be so careful doing shite like this not to destroy a good scope.
