Cheap Tubing Notcher for your Lathe

A milling attachment is heavy and cumbersome, and there is always the chance of accidentally dropping it on the ways. I came up with this piece to cut notches in tubing without resorting to a milling attachment.

Chuck up a hex shank hole saw, mount this little attachment, and you are good to go. The longitudinal power feed makes it automatic. It cuts solids like butter as well.

This could also be mounted to a QCTP by bolting or welding a piece of square stock to the back side that matches the QCTP tool holder, 3/8, 1/2, 5/8 etc.
What RPM, feed speed did you use for that size pipe?
 
Don't recall the RPM or feed rate, as this was about 15 years ago. Pretty slow though.
