Video on 32mm thread?


 

Don' think that will be cut with a normal threading bit.? ?(Yes, I endured the insufferable youtube ad to see this)? ?8^)

Hi Lone tree. I cut my thread with a normal bit.

The item was an adaptor to join additional? lenses to a Canon G2 digital camera.

It was an internal thread, 40mm dia, 0.75mm pitch, both ends !

Worked fine and completed on an imperial lathe.

You may fine up to 4 TPI [ 6mm]. Most time it is under 8 TPI [3 mm]
