looking for lathe chuck.......

[brian923]

now, i am not a machinist so,,, i don't know all the machinist lingo, or the correct terms, but i am looking for a part for my father-in-laws lathe. here goes.....

he referred to this type of chuck as a "3 jaw buck chuck"
i guess the name of the first manufacture named it the "buck chuck"

it is a 3-jaw chuck that can be adjusted after its tightened. it adjust the centering alignment after its tightened. his machine is older and is a threaded spindle type.

i am wanting to know if there is anyone out there that has one and wants to sell it, or where i can find one. thanks allot gentlemen, Brian

It's commonly referred to as a set true or adjust true. Several manufactures make them and places like MSC sells them. Buck is a brand name and is a fair chuck, Bison is another one.
