Doesn't seem to be a lot of meat for holding stock on those little bitty steps. From here it looks like they are 3\16ths" It's about a 3" chuck.
I really want to flip the collared bushing and chuck it up in the reversed jaws so i can trim the diameter to match the drill press handle. No bushing there originally, and this one is pretty close and fits the shaft perfectly. Its just the OD of the bushing is just a little big. Seems like a worthy first task and it will beef up the drill press attachment a little. Also the bushing is bronze.
Looks possible as long as oversized work is properly supported, but I'd rather ask first.
Thanks!
