so I have this 57-year-old 1460. just finished setting it up, servicing, cleaning etc. went to remove the 3 jaw and ran into a snag. I spent 4 years or so with my 9" SB model A, but this has an L1 spindle nose. it came with the original spanner wrench (actually 2 of them). I put the machine in low gear, had to tap the wrench with my lead hammer and the big nut came loose. lefty loosey. it spins freely about 1 turn then stops turning. should I just whack it (the wrench) with the hammer again? not sure and I don't want to mess this up. thanks.
