I think Wells is still in business, parts I think may still be available new. First order of business is tying up the missing power feed part, whether you buy a power feed to install or make some spacers or whatever else is needed. I agree on price, I lowballed on my mill and they bit, from a dealer no less. The tooling is spendy and rare, although I have heard that you can modify a standard 30 taper holder to work. You would have to have access to a surface grinder and build a fixture and know everything needed to do it right, not sure a novice need apply to that lol. It does have a big ol table and generous travels. Flakes are visible, nice, are the ways hardened? I was driven away from several bridgeport because my mentor b**ched at me for even considering a bridgeport without hard ways. I ended up with a clone, with your guessed it, hard ways lol. It becomes more important if you ever plan to cnc it, and who doesn't wish that. One major plus, it's big ol quality American cast iron, nothing compares.
Make sure the power feed actually works, goes down...
Also turn it on and let it run for 20 mins at least and feel if the quill and head surrounding gets warm or hot. Mine can run for hours and be warm. Do this test at 1000rpm for 15mins, then bump the speed up 1000rpm every 5mins until max speed. If the bearings are shot and it gets hot have fun with that, the teardown and the price of the bearings....
