Here are a few pics of the unloading, and a few shots of it in place. I was going to store this out of sight up in one of my storage spaces next door and leave it until next year when the new shop area will be complete, but found room in my existing shop area. Definitely not at the top of my list this year, but going to try and get it cleaned up, possibly painted, and wired up and running in the next month or two. This thing is definitely a beast, the machine weight is 1650kg or for the metrically challenged like me 3630 lbs dry (has three lube reservoirs + large flood coolant system with a BIG pump) and without chuck or tooling. The spindle thru hole is 2.25" and the longitudinal lead screw for the carriage is 1.5 inches in diameter. Swing over the bed is 14", and with the gap section removed is 22", 40" bed length. Motor is 7 hp 3ph with a soft start function which can also be setup for an almost instantaneous stop. The spindle is clutched and is driven by 4 V-blts from the motor, 16 speeds from 14-2500 rpm, metric and inch threading. The chip & coolant pans along with the rear splash guard are still in the truck and also need a good cleaning. Overall it seems to be in very good shape and ran very smoothly when I checked it out. Came with a 3 jaw Poland chuck, qctp, a second D1-6 chuck mount, center and steady rests, a live center, and a Albrecht keyless chuck, and a two axis dro. I think I'm going to really enjoy this machine. Thanks for looking, Mike

Congratulations! Those are great machines! One thing to be careful about is make sure you wire your motor rotation correct. TOS lathes use a gear pump to supply oil to the main spindle bearings. If the motor spins the wrong direction everything else will work fine but you'll starve the spindle of oil. I have an SN40 and wouldn't trade it for anything.

Thanks, I'll be sure to keep that in mind. Do you have a manual for yours? I've checked on line and haven't come up with anything. Thanks, Mike

I got my set of manuals off of eBay. Search "TOS Lathe". The seller MikeKandu usually has some for sale. Be sitting down though, they're pretty pricey.
