The bass’ (and cello’s) endpins usually don’t get glued in – as both the plug and the hole are conical, the endpin gets just plugged into the body. But some endpin plugs are really a challenge to get loose again. The best way I found so far is to use a hammer without handle. I screw the rubber tip off, slide the hammer onto the endpin, and screw on a large washer (as I don’t want to damage the rubber tip). Usually, it takes just two or three blows with the hammer to get the whole endpin assembly out off the bass’ body again.
I have an end pen that went back into the body of the cello. Would it be you suggestion to find another end pen, follow the method the you have prescribed, thus removing the whole assembly, getting the end pen out of the cello and then reinstalling the assembly? Mike
Any ideas on removing an end pin that is cracked in half right above where the metal piece with the thumb screw goes?
