So I currently have 2 3 jaw chucks, a 12" that requires an engine hoist to install, and a 8 inch that has a couple of broken teeth in the tightening mechanism. I typically use the smaller one, but it has quite a bit of runout as well. I also find myself switching between the 4 jaw, collet chuck, and smaller 3 jaw pretty often. I see that Abom79 has a 6 jaw that he says is better concentricity wise than a 3 jaw, so I figured I'd give it a shot!
I found a cheap backplate for my lathe that has been left unused for a while (L1 backplates are worth their weight in gold it seems!), and bought this: https://www.ebay.com/itm/6-jaw-chuc...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649
My 4 jaw is the same brand and seems reasonably good, and I plan on surface grinding the face if it seems too far out. Despite being the cheapest one on ebay, the seller seems to have shipped via UPS quite quickly (despite a month long expected delivery date, I should be getting it in roughly a week overall, this Thursday). I'm cautiously optimistic that this 6 jaw will be good enough to just use on the lathe!
