This machine was purchased by the NY Air Brake company in Watertown, NY in 1954. Its a tool room lathe with a taper attachment and lead screw reverse lever on the apron as opposed to on the headstock with their engine lathe. This is a Model 60 lathe with the gearbox of a model 61 according to Monarch. You can quickly tell this from the round dial on the front. This is a totally enclosed gear box, as opposed to an open gear box on an earlier model 60 or the C series lathes. Many model 60 lathes were made this way. Machine has the original 15hp motor and its a huge 326 frame size. The motor barely fits in the cavity below the headstock. Largest motor I've ever seen on a machine tool. The modern equivalent would be 50hp in the frame size to give you some perspective. I bought this lathe at an Auction in Adams Center, NY, just about 10 minutes from Watertown, NY. It now resides in my shop about an hour from the NY Air Brake where it was purchased. It included a 3 jaw, 4 jaw, Jacobs Flex Collet chuck, Jacobs 14N and 18N drill chucks, a live center, and a face plate. Machine has a D1-6 camlock spindle and a #5 MT in headstock and #4MT in tailstock. These lathes are extremely heavy, by far the heaviest machine I've moved. I used a tow truck to move it and that was the best decision I made in moving it. I rented a toe jack to lift it onto some pipes to get it out from its spot in the previous shop, and that too was a wise move. You cant just use a prybar to lift up 8,000 lbs of machine, its just too heavy. Monarch told me the motor was dual voltage, but the starter was single voltage only. That was true because the coils on the original starter were 480v, although the starter was a size 2 starter, large enough to run the 15hp motor on 240v. I rewired the motor from 480 to 240v, and bought a nearly new size 2 reversing starter with 240v coils from ebay for a couple hundred bucks and the machine came right to life. I was lucky enough to use this lathe for about 8 hrs prior to the auction where I bought it, and its a beautifully running machine, although terribly dirty. I began cleanup in the photos below and will continue as time allows. I also found a nice Aloris CA size tool post for it with 10 different tool post holders at an auction only a few days after I bought the lathe. These lathes are beautifully made and wonderful works of engineering. I'm really looking forward to using this one.
