Does anyone know the maximum inside jaw capacities of both(the 3-jaw and 4-jaw) Harbor Freight 4" self-centering chucks?

The information that HF provided listed the 4" 4-jaw self-centering chuck as having a maximum inside jaw capacity of approx. 1.3" but that sounded too small to me. Is that correct?

Also, any information on the 4" 3-jaw chuck from HF would be appreciated.

Basically, I'm looking for a self-centering chuck to fit the asian(Seig) 7x12 mini-lathe with an inside jaw capacity of at least 1.5". Thanks for any information you can provide!

I will check mine tomarrow and let you know. Check out this site
http://www.littlemachineshop.com/products/product_view.php?ProductID=1588 littlemachineshop sells and has great info on all mini lathes and milling machines.

mini-lathe.com has the capacities charted here:

Chagrin,
That's where I got my information from on the capacities and the reason that I thought the 1.3" from HF sounded low. :confused:

CNCadmin,
NICE forums! :D
Been there(LMS) as well...:) And yes, LMS provided plenty of info on their 4" chucks. Prices were a little higher on the 4" 3-jaw than HF's and I was really interested in the self-centering 4" 4-jaw that HF has. I was wanting to make sure either of these chucks from HF would meet my requirements before I purchased one and hoped that someone who already had one could check. Thanks for any information that you or anyone else can provide on their actual capacity.

cncadmin,
Have you had a chance to check the capacity on your 4" chuck yet? Is it a 3-jaw or 4-jaw? Thanks!

I sorry, i'll do it today, I have 4 jaw and a 3 jaw.

Here is a pic-

Thanks cnc!
I was really interested though in the capacity with the jaws reversed? As long as either the 4" 4-jaw or 3-jaw will hold 1.5" dia. stock with the jaws reversed, that's all I was looking for. Is your 4-jaw self-centering or independent? Thanks again,

Rob

It's independent, the 3 jaw will hold 1.5 with the jaws reversed.
