I recently inherited a Cameron Micro Drill Press Model 164. It has an Albrecht 0-1/8" Keyless chuck and it works great but I'd like to be able to use a little larger bits so I think I need a Jacobs 0-5/32" key type chuck or maybe and Albrecht 0-1/8" Keyless.

Does anyone know if the shaft chuck taper is JO or a J1 or have any idea where to get the chuck I need?

Thanks.
