Here is a student cello where the end pin block was collapsed because the block was broken in 3 or 4 places. Normally I would take the top off and repair or replace the block, but since this cello wasn't worth that repair, I tried to fix it without taking the top off and it was saved from the dumpster. Here are some photos of that proeess.
