I've worked on a Bridgeport for many years and yes that would be the right choice except it would not fit into my basement as to height. A few years ago I was thinking of buying a small mill from Grizzly but now I do not do as much as I used to. My shop is really set up for woodworking, but I do have a small Grizzly metal lathe that lets me make small projects. On my 20" drill press I bought a XY table and made a barrel wall thickness gage like the one that Glazan had. There are two rods one for 10-12 ga and the other for 16 ga., and I can get repeatable readings taking the barrels off and back on. As shown in the picture I can reach 16" into the barrel from breech up, but on a tight choke 12 ga. the muzzle end will not fit over the rod. (5/8" rod.625 plus half diameter of ball .0625
