Hi all, Hope you engineering experts can help with this one. I have a Supernova Standard Z chuck which if fitted with a insert that takes it down to fit a 3/4 x 16 tpi drive.

I have removed the insert but the thread is too big to fit the drive on my Record Maxi 1 which is 1 1/4 x 8 tpi.

There is a part listed on Record Webb site but this is for the Supernova 2 chuck and although the internal thread will definitely fit my maxi lathe I do not know if the external thread will fit into the Supernova standard Z.

Hope this males sense ?

Cheers

Vic
