Yep, 80mm80 mm?
I already have a chinese 3 jaw chuck with a 5C collet mount and it is fine.I have 3" (80mm) chucks brand name Harlingen in various jaw configurations. Because of the size they are super useful. I also bought their 5C backplate arbor to mount in my 5C SpinDexer. Or make a plate for various setups. The Harlingen (made in China) is very accurate. Other brands out there have variable quality. The similar looking 3" 3J from Accusize was quite bad, it got returned.
Oh yeah, I want a nice grinding chuck one day but damn things seldom come on the used marketGotcha. You probably know this but grinding chucks offer models that are up the cuteness scale. Typically longer length, slender tipped jaws, smaller minimum closing diameter & usually 6 jaws. The bit of messing around I've done on my TCG I get it now. There are setups where the tool & wheel & fixture holding device want to occupy the same real estate.

Nice chuck.I found this Pratt Burnerd Int 80mm 3 jaw chuck a while ago and finally got around to picking it up the other day.
You know, I have to say it.Nice chuck.
Here's my cute old Burnerd (not Pratt Burnerd, and made in England) chuck, mounted on the dividing head for my Burke #4 milling machine.
Found it at a yard sale in a tiny hamlet north of me and reluctantly forked over two bucks for it.

oh damn, you must have studied russian literature, or english litNo, I don't.
You'd only laugh at me....
What I studied is irrelevant to this forum. What is relevant is that way back then I spent my summers as a machinist's helper in an industrial setting, and learned just enough to be dangerous. That's why I still play with lathes and stuff.oh damn, you must have studied russian literature, or english lit
