Peerless Jewelers Lathe ,drill chuck

[roberthorneman]

I have a Peerless 8Mm jewelers lathe. I would like to add a three jaw chuck. Are there chucks with arbors available to fit the drawbar?
Also what is the metric thread size of the 8Mm collets ,M7 -0.75 or 8Mm- 1.25 or something else?

Hi Roberthornman,
I held back posting a reply hoping someone might know the metric equivalent. I do know that the inch size is .275-40 tpi.
Also would think that you could find a used 3 jaw chuck on ebay using this sized WW collet. My 8mm 3 jaws have both WW collets and Moseley long conoidal collets so I know they were available at one time.

Sorry couldn't help more Robert,
Bob
