Little gear drive Swedish milling machine I'm using. It's really just a mill drill actually, but it does ok. need to fix the quill spring, she'll just drop without the clamp tight. I wish this was an R-8 collet, it's an old style Morse though. 220 volt. On it's second owner, I'm not sure how old it is, but I think 1960's sometime. Retired Boeing engineer used it on his hobbies. I'm trying to find out more about him, long since passed away. It's been in Bill's garage for 20 years. I'm slowly cleaning it up while he's not looking. It has dozens of oil pots and grease zerks on it, and adjustable ways. It's got some play in the head bearings, to be sure. I haven't yet swept in the head and put the indicators on it to see what shape it's really in.
