3 jaw

I like Shars stuff. This class of chuck will do a lot of work, and Shars' quality specs are better than most China distributors. It would be a good, general-purpose chuck that will be a workhorse in your shop.

That said... If you want to have a tasty-sweet chuck that can have the eccentricity dialed out of it and moves smooth as silk, you can get a Bison, Burnerd, or Buck (good chucks start with the letter B) and never want for another chuck again. You'll need one of these to chase tenths (or even half thous) in your work. They cost a ton, but aren't so bad used. But I warn you, if you go this route, you'll never be able to appreciate, let alone use, a sub-standard chuck ever again.

Still not an easy decision.

Enjoyed this, @pontiac428 ! Chuckled several times (... good chucks start with the letter B) and ... chasing tenths (like a good hobby guy should). Good advice with tongue firmly in cheek!
 
Hee hee - to add further confusion, my Bernerd 6" actually says Pratt-Bernerd on it. If my wife had known what I paid for it, I might be single today. Fortunately, the statute of limitations ran out several decades ago. :cool:

However, I agree in general with the Shars comments given above. I don't think that you will regret buying it.
 
The early ones only said Burnerd on them, before Pratt aquired Burnerd. The PB chucks these days say PBA on them. Not sure if PBA stands for Pratt Burnerd America or Pratt Burnerd Atlas.
 
I'm going to check what's down the basement , but I think a Bison and maybe a Tesa are left . Waiting on later this month to see what's up the other plant . Hopefully the lathes up there have their own chucks with them and I can move the extras .
 
well I pulled the pin its on order. first time ive ever ordered from shars, Ive had stuff in my cart a few times and looked at the shipping and said screw that.... even this item is 20.oo delivery I know its a heavier item but seriously 20 bucks??? I tried adding a few other ounce items on the order and that 20 bucks just jumped up even higher so I deleted them. you would think mailmen were all millionares with what shipping costs these days

$20 shipping for a chuck is not bad at all. Shipping is getting expensive & it will just keep getting expensive. Seems like not that long ago USPS flat rate small box was $4.80. Now it's up to just under $8!

For Shars, check their ebay store to see if the have the item listed. Many times it's cheaper on their ebay store with shipping than on their website, well for small items, I've never ordered anything heavy from them. I never purchase through their website because of their high shipping costs for small items.

I don't know just when Pratt bought Burnerd but mine was bought in late 1981 and says:

Pratt
Burnerd

well its here... now I just gotta clean it up and fit the mounting plate... quite large looking compared to the old 4jaw... remember in the pic the mounting plate isnt on the 3jaw yet and it still dwarfs the 4jaw.. could use some wisdom on what all I have to do to machine it down... looks like I could take a 1/2 " off that snout too as you see in the pic the theres quite a bit of thread not being used.29245620190411_135638.jpg20190411_135626.jpg20190411_135714.jpg
