Don't know why I forgot that darn center tap issue. Stuck in a lab all day without windows can play with your mind - :cheers:

I just got done scanning over those pics from the Fitch Williams rotary converter. Is there any other info out on the web that you know of about this that I might go and look at? I poked around for a while and haven't found anything yet. I like the idea of placing the motor on a cart for mobility. I hopefully getting a 7.5hp motor and may give it a try. Although I admit I'm a bit skeptical about having that much motor ready to do a flip from rotational torque. Do you see any problems down the road with that?

I found it Al, it took me a while! Seems like Fitch Williams hasn't posted anything lately on the forums. However I found
someone that saved his work in .pdf format on Practical Machinist. Here's the link:

If anyone would like it email me if the above link fails to load.
