So I have a need to turn some 7" diameter 8620 in my PM-1030V. Obviously this is significantly too large for the supplied 3 and 4 jaw chucks.
The workpiece is just a small sliver, 5/8"-3/4" thick. I'm pretty sure the lathe will be just fine but I need to hold the part and face off the ends so I need full access to both sides. I don't care about turning the outside diameter, it should be fine as-is.
I was thinking of using the factory-supplied faceplate and drilling/tapping 4 holes in the stock and bolting it to the faceplate, then reversing it so I can face off the other side. Advisable? How do you center the piece on the faceplate though, just lots of trial-and-error? Does it even matter that much if I'm only facing off the ends?
Alternatively, I was thinking a 6" 4jaw might be able to grab it on the outside diameter with outside jaws. But I don't see any way of getting a 6" chuck on this machine, has anyone done it and would it be worthwhile for this endeavor? I'm assuming trying to use outside jaws on a 5" chuck for 7" material would be...ill-advised? Maybe, maybe not?
Any other options that I'm not thinking of?
TIA!
