Left Pic – Broken String Bass End Pin with part of it still stuck inside
Right Pic – How else would you get out a broken bass end pin….a valve slide expander, of course…

Left Pic – I just slid it in, tightened the knob to expand the end a bit, and pulled the broken piece out
Right Pic – Replacement end pin is too big; it will need to be trimmed down

Left Pic – Chucked up in the lathe and slowly trim down the taper
Right Pic – Checking with the calipers

Left Pic – almost ready to go…final fitting was done with a band sander
