Lachmiller single stage 12ga press

[STP22]

Had one of these single stage presses come to me at work and after a bit of research, have yet to determine how to remove the sizing die from the press. I want to do what I typically do with an item this age...strip, clean, lube, then reassemble it prior to moving it along to someone that can use it. What is the procedure to remove the sizer die from the press?

Regards,

Scott

There is a set screw on the right side of the press.
