Lathe Parting Tool Spring Type Tool Holder For QCTP

Nice work JR
This certainly reduces the tendency for the tool to dig in and grab any backlash in feed screws.
Have you thought about achieving the same result with a rear tool post, both approaches will allow the tool to move away from the work under cutting forces. I use tipped inserts in my parting tool and have parted of 3 inch blanks with auto feed on occasions in my SB, it has plain bearings and is one of the few times I think it may help with less vibration.
Thanks for posting.
