I have the LMS OXA QCTP on my Sherline lathe. Other than being a hair large for that lathe I have no complaints. OXA should be just right on a 7x14 lathe.
Aaron, can you clarify what you mean by "a hair large"? I need to buy a QCTP for a new Sherline I am refurbishing for a friend and the tool posts I used to buy are no longer available. Not sure if the OXA is the best choice.
