Peter:
It's been a long time since I fit one to my 14x33 lathe. That required no machining to the lathe itself. My lathe has a large T slot on the cross slide to mount the tool holder. To mount the QCTP I only needed to machine the plate, which came with the QCTP, down to fit the T slot in the lathe. It wasn't a big job, especially with a mill available.
Send pictures when it's on.
Thanks.
Hugh
