I've got a mangy old benchtop drill press that's still in reasonably good shape for rough work, but the teeth on the chuck key are almost completely worn out. If I could find a replacement key I could keep this old soldier going for quite a while. Does anyone know of a table for the Jacobs chuck keys that has the critical dimensions for each of the keys? If I could find this information I could just take the dimensions off the old one and look up a replacement.
Thanks in advance, Tom Dacon
