Good God, Harald you would need a second Mortgage for those!!!!!

When I had the octagonal 'no eared, no spinner' variety, I used both a Ledgerwood tool and also the part that MWS make.
I'm currently switching over to two eared spinners and the plan is to go with a mallet( either hide/hide/ or hide/copper)
