I picked up an old 6" Sampson 4-jaw scroll chuck for REALLY cheap ($10). But it only came with outside jaws.
Finding inside jaws for this chuck is VERY unlikely so I thought I'd grind down the existing jaws to accept a set of Top Jaws. I have the equipment to do that - except the jaws are hardened so drilling and tapping holes in them for the Top Jaws seems like a show-stopper.
Is it?
I also considered making a set of jaws but I'm stumped on how to cut the back side of the jaws - you know, the curved groove side.
Ideas?
