I acquired one of these 1891 paper shell crimpers that states the head is Reversible. Now I know what that means:: that it will do a standard roll crimp or a square crimp.
My question is -- does anyone have the instructions on how to change/move/rotate the pins or head in order to get one or the other crimp? Right now it is making a very nice roll crimp but I cannot figure the alteration process to go back and forth.
Any ideas, knowledge and/or known youtube video would be appreciated.
