Hi Steve,

Are you referring to this para?

Quote:It is not possible to insert a tool or tool holder with internal threads into the work spindle first and to screw the tool retaining/forcing screw into the internal thread afterwards! The tool or tool holder must be screwed onto the tool retaining/forcing screw.

If it is, I read it as having to screw the tool retaining/forcing screw into the spindle first and screw in the tool or tool holder with internal threads M10 onto the tool retaining/forcing screw. The tightening is done using the allen wrench and the retaining bolt (referred to as holding pin in the text while the diagram uses the term retaining bolt) to draw in the tool/tool holder.

The Sherline folks have done similar modification to their mills using a thin downed nut to squeeze out the tool holders from the taper. Some use a rod inserted into the spindle bore from above, fastened it to the top of the spindle, and turn to break the taper.

Regards,
Wong
