I just purchased a new 4-jaw 6" chuck from LMS. My theory is always buy as big as will fit and what you can afford. No problem with LMS, they are great.
When I opened the box I know I had made a mistake. WAY too big for my needs. I probably should have gotten the 4". Most of what I am doing now is small steam engines and the little Unimat 4-jaw I was using just didn't cut it. I will keep the 6" and buy a 4" later. I guess the moral of this purchase is "bigger is not always better"
I have a Maximat V10-P.
Machining the back plate and drilling the holes is another complete story, but it fit and a Starrett Last Word DTI shows less than a needle width TIR.

Re: New 4-jaw...wish I could turn back the clock!!
I bought an 8” 4 jaw for my G 9729 lathe but I think running it all time would be too much weight for the spindle bearings, staying with the 6” max.
