Today I bought an old Forkardt F160 3-Jaw chuck for $15. I think the seller assumed it was too old/siezed to be worth anything, but I've pulled it apart and am in the process of restoring it now. Internally there is almost nothing wrong, it was just a little gummed up.
I've never heard of a "wedge bar" chuck until now. Can anyone tell me what the advantages/disadvantages of wedge bar chucks are, or why they would be used over a typical scroll chuck? Are they supposed to be more accurate than a typical scroll chuck? I'm just curious to know about it as I can't seem to find much information online.
Also, what is the best lubrication to use inside when I put it back together? Or should it be dry? It seemed to be lightly oiled when I opened it up.
Thanks
