Hello all!
The things I intend to fabricate are audio microphones accessories. (I am a sound engineer)
This pose a few problems.... I own a Precision Matthews PM1127 lathe. This is a nice machine and I am happy with it, but the most standard thread size for mounting microphone bracket is 5/8"-27tpi On the charts given on the machine, there is no gear combination to cut this thread!
Also, I build my own microphones and I would like to learn how to cut fine threads like the ones used in photography lenses and filters.
This way I can use some nice capsules I have (Schoeps, AKG etc) to preamps and contraptions of my design or design accessories circuits like pads and low-frequancy roll-offs...
For those who don't understand this giberish,,, it all boils down to be able to thread fine threads on thin tubular brass or aluminium tube.
Right now I have no specifications to give, it is more the technique of holding the parts in a chuck, what geometry the cutting tool should have, how to avoid distortion in the finished parts...
Sincerely, Luc
