A2-6 Direct mount help

[Chris_Metalworks]

Hi to all,

I am a new member and I have a very simple question. I have an old Takisawa TC-20 Lathe with a 16C collet chuck, which is missing the closer. I am trying to find out what the thread size is on the spindle so I can machine a thread to make a closer.
Any help would be great.

Chris
