I have been looking for one of these for quite a while. I finally got my hands on one this very morning! It's a machinists vice. One with an X-Y translation stage as an integral part of the vice. Basically, it can turn my drill-press into a limited capacity milling machine! Sort of a mini Bridgeport!
I actually saw this vice last week at the little flea down the hill from Wal*Mart in Lunenburg. Unfortunately I didn't have the cash on me at the time to buy it. I would have right then and there if I had. Mum and I made a special trip out there again today in hopes that the vice would still be available. As I said last week to the guy selling it "If it's meant to be it will still be here. If not, well, ..." such is life. (or some such. I don't remember my exact words.) Anywho, it was still there today so I snapped it up.
It seems to be in pretty good shape. I have no idea how old it may be or how much use it may have had over it's life so far. I also haven't found any builder's plate or other identification as to who made it. It does need a good cleaning, lubrication and adjustment. That is to be expected with this type of machine tool. I will also have to replace both cranks.
Even after it's all cleaned up I don't expect to be doing any real precision machining. I'm not sure mild steel is really a possibility using this with my drill-press. Aluminum and other soft metals, plastics and maybe some wood should be workable using this rig.
First I need to clean it up and get it ready for action. Then I need to dream up some things to make with it.
This is going to be fun!
