Fellas,
I've gotten my hands on one of the Albrecht keyless chucks. An expensive bugger that I laid out $100 for and that was on eBay, fer cryin' out loud! (It was pristine, I didn't want a worn out POS)
I'm not sure this chuck is worth it. Not that it's bad or seems poorly made, mind you, I just have a hard time imagining that it grips tight enough. I've spun a few drill bits already and am thinking of retiring it and going with a keyed model.
I'm looking for an all-round high quality chuck with good grip to use on a Bridgeport.
How 'bout them thar Jacobs Super Chucks? I'm familiar with 'em, but don't know if there are issues pertaining to the different sizes to think about. I'm leaning towards a 16N, which goes from 1/8" - 5/8". This ain't a small chuck, but not as big (and heavy) as the 18N, and nowhere near as big as that giant honker, the 20N.
Silver and Deming shanks are turned to 1/2", right? Soooo, the 16N would accept any normal drill or reamer up to 5/8" and all the drills in a S&D set. I can't see normally chucking up anything much larger than this. I've got a 3MT tailstock on the lathe and a 3MT toolholder for the mill, so if I ever need big, long drills I'll go with taper shanks. And I've got TG-100 collets for chucking endmills, so what I need from the milling machine chuck is to grip average size straight shank drills and reamers.
Anybody follow my reasoning h'yer? I guess what I'm trying to do is figure out a balancing point between sturdiness and weight. You could chuck up an 20N all the time and have it covered all the way up to 1". But that is a lot of weight to be swinging around out at the spindle end, I don't see this being good for the spindle bearings, etc. Seems to me maybe the 16N is a good choice. But how about the 18N? Is this maybe a better one, not being too heavy, but stouter yet?
I'm leaning toward getting the 16N for everyday work, and snagging a 20N eventually off eBay for the odd time or two when I'll need something really big. Seem like a good plan?
