So bear with me on this or maybe the I-phone users will point me to an easy way. My new Android also saves pics in HEIC so that windows cant manage them.
It does however put them into google photos so i can download them . I then use an online converter for jpeg, so lets see if it works.

First shows my adaptor for tool block fitted to slide using existing tapped holes, and my initial attempts at a "rear" parting off toolpost .
Second shows improved PO toolpost, with T37 tool block above . I am using a narrow tip tool for the sort of profiling which is generated by Mach Wizards .
Have to say that Mach 3 wizards have some very inefficient routines , but like the old bike , good enough to learn on.
