This machine is pretty unique and rare, I had to have it. Came out of Boeing/Douglas, I bought it from the guy that got it from auction. It is marked 440v only, but I reconnected it for 220v. It has a high frequency directed drive 4/2.7 hp motor. The frequency converter that came with it puts out 360/240 hz. which gives speeds of 21,000 and 14,000 rpm. It's in real nice shape and everything works with no broken parts. I called ATS the company that supports Onsrud machines and they have never heard of the model. I'm planning on mounting the converter on the wall behind the machine, but it probably weighs 500 lb so I'll have to be careful. thanks for looking.
