Hi Charlie!
First off, let me be clear that this is not my work, but the work of a very talented man, Robert Fumanarek (sp?) (). John and Robert go back a ways, from what I gather...two gifted and creative people!
With that disclaimer out of the way, yes, the existing screws are removed when mounting the plate and (possibly) replaced by socket head cap screws that are 5mm longer. The motor is also rotated and shifted rearward via a motor adapter to retain the? Sieg OEM motor mounting method. As I understand it, the engineering goal was to minimize alterations to the mini lathe...an easier (if less elegant) GR implementation, to my way of thinking, is Ralph Patterson's jackshaft design ()...but I agree, a GR is very nearly a must-have on these small lathes.
