So, I'm looking to buy myself an independant 4-jaw chuck for my little lathe (8" swing), and (as usual) I'm confronted with a huge price range from £60 at the bottom to six times that at the top.
Unlike scroll chucks where you pay extra for precision scrolls and the like, where does the money go in a 4-jaw? The only thing I can think of is the material the chuck body is made from, but surely there must be more to differentiate a bargain basement nameless import on ebay from something by Bison which costs a good chunk of the value of the lathe.
I'm prepared to make a bit of an investment here, as I don't want to be stuck with something that is going to be an irritation or limitation in the future. On the other hand, I'm not keen to pay a 500% premium just because the chuck's been finish ground by naked Balinese maidens but is otherwise identical.
Advice much appreciated!
