Does anyone have a good source for the odd sized padlocks for locking the "on" switches so unauthorized people cant use a tool? I am going to be away for a while and have visions of my wife cutting frozen chicken on my bandsaw. I need a padlock with a 3/16" diameter shackle for my Unisaw and 2 locks with 5/32" shanks. The shackle on the 5/32" locks needs to be 2" long.
