Freak front thread spec?
 
I have searched high and low for this and I'm hoping someone in MCB can answer my question ...

Does anyone know the thread specs for a freak front??? - I would like to make my own front (out of another barrel)

Thanks in advance for any help.

If you have Autodesk Inventor you could use the specs from zdspb

not sure on major or minor dia. but the thread is a 16tpi dual lead. i just measure a freak back over the threads and turn to that, then thread till the back fits.
