I just got a cheap drill press from Cummins tool.  I'm sure it is the same thing or very close to the ones sold by Harbor Freight.  The chuck was not installed and I am wondering how to install it.  It looks like it just pounds on, but I don't see how that would keep the chuck from just spinning on the shaft it attaches to.

So, how do I attach it?

Believe it or not, it's mostly a friction fit, assuming it uses a standard Morse taper.  Square the table to the quill with the greatest accuracy you can.  Make sure all the mating surfaces are very clean and dry.  Place the chuck (with jaws retracted) on the table and bring the quill down on it firmly.

Your chuck is now installed.

Ok, that's what I did to install it.  I figured there was a taper, but it just doesn't seem right.  I went to the instructions, but there was absolutely nothing about assembly in it.  I love the instructions made in china.  Thanks Blammo for the reply!

My pleasure!  It should've come with a drift (somewhat triangular slug of metal) that you insert in a slot in the quill and tap with a hammer to knock the chuck out.

I bought one of those cheapy chinese drill presses at a Cummins Tool Sale as well. I thought mine was missing the chuck instructions as well. I just lined it up and with a rubber mallet, gave it a bunch of wacks until it was tight. Its been working just fine, although the chuck will occaisonally have problems. It gets hard to tighten, andit feels like the internal gears are messed up. Its OK now, and Ive used it to remove a bunch of rivets and build a bunch of rifles. Here's a question. Is there a trick in moving the belt that controls the speed of the drill?

ahhh, the drill has a head on it, you can open the Gear box right?  Like opening a coffin door.  

See the two spools?   One of them is spring loaded (I don't remember which) push/slide it toward the other spool and you'll put slack into the belt.  Move the belt.

Sorry if I'm answering the wrong question.   It's pretty simple

Just got a ChiCom drill press, too.

My operator's manual says to tap the chuck in with apiece of wood.

I'm glad to see that I'm not the only one to use the "much sought after" chinese drill press.  I have seen on other posts that people go out and buy a new chuck because the supplied one is terrible.  It looks like they end up spending more on the chuck than the drill cost.

I did not get a drift either.  Hopefully I don't have to take the chuck off.

 That taper is called a "Jacobs taper" and comes in five or six flavors.  You have to assume the chuck fits it.  

 All you need to do is slide the chuck onto it and bump it on tight.  Do not pound on the fingers of the chuck  -- Spin them up inside the chuck body first.  To remove a JT chuck, just pull on it and tap the driveshaft with a brass drift that fits all the way up inside the chuck, against the end of the tapered shaft.

 If you are unsure about the specific tapers involved (My Taiwan press was mislabeled), Just get some crude measurements of the taper and compare them with the JT specs listed in the Machinist's Handbook, or  on the chuck info page of the Victor Machinery Co. website.

If your chuck still continues to come loose, try degreasing the socket and the shaft, apply a drop or two of locktite and reassemble as described previously.
