BSP Tread on Myford 254

[ray jones 1Participant @rayjones1]

Hi

I need to cut 3/8 BSP external thread on a project.

I need 19 TPI.

Using my imperial Myford 254 my only basic options are

18 TPI or 20 TPI

Any suggestions how to achieve 19 TPI please .

many thanks

Hello Ray,

​Use a 38 T wheel in the chain to get a multiple you can work with.
