Not done it….. shame you have had bad experiences with the sc. 4 jaw. Mine is brilliant, but non round stock? Bdms is quite round I have experienced no problems.. often people are expecting micron precision for the price of a bacon butty .
I can take a piece of work out, put it back ( which I avoid at all costs) and it’s within 1 thou without any special precautions , I like bacon but my chuck is a basic level TOS chuck and I stand by the accuracy statement
If you use extra pieces to bulk out to a square shape for the 4 jaw s.c chuck, double sided tape is a great aid to hold it all together while setting up. Still think the faceplate is best though
Edit, …blasted autotype with technical terms on the pad!
