I recently purchased a 16.5" jet drill press. I got to the end of the assembly and I noticed that the arbor would not go down fully into the chuck. Upon putting the arbor and chuck into the spindle, I turned it on and had a large wobble in the chuck. The bearing seems fine, but as I look into the open end of the chuck, I can see that the arbor hasn't reached the mating surface that it should meet. I took the machine back, got another and had the same problem. Any suggestions?

Drill press issue
Is the chuck keyed? The flats on the top of the chuck should line up with the slot in the arbor.

Do the chuck and the arbor have the same taper? Chucks are nearly always Jacobs taper as is one end of the arbor. The long end of the arbor is usually Morse taper.Is the arbor taper and the quill taper the same? does the tang on the arbor fit in the slot in the quill? If yes to these, are there any burrs on either the chuck or arbor? Is there any cosmoline or other corrosion preventative on either one? If yes, remove and polish. Must be clean. If no, clean anyway. then, put the arbor in the quill and check runout. By snugging up the quill bore some runout can be removed but do not squeeze quill. IIt should still move freely. If still out, remove, turn 180dg and reinstall. Check runout again. If still out, thats not unusual for Jet. At this point, go to your local machinist supply and buy an arbor and chuck of good quality and have them mount it.
If the runout is acceptable, freeze the arbor overnight in the deepfreeze. Heat the chuck to 300 dg in the oven. Have the dogs in the chuck turned down flush or less. Have a brass hammer and a piece of 2x4 handy. slip the arbor into the chuck and give the tang end of the arbor a couple taps with the chuck set firmly on the board. If the tapers are true, this will seat it squarely. You have only a couple seconds to do this.
Good Luck. Personally, I'll never own another Jet tool
Is this the right "Jet" tools that we're talking about?
They are available in Canada through USI / AGI distributors.
(USI = "Uni-Select" ... Auto Parts Plus, Bumper-To-Bumper)
(AGI = "Acklands/Grainger)
Made off-shore ... China, I think.
They also have a "cheaper" line ... "ITC Tools"

It was a "tongue in cheek" kind of comment, lot's of sarcasm intended, Chinese made.

I appreciate the advice, but I shouldn't have to go through this kind of hastle for a new machine. So Jet's=no good huh? What kind of presses are recommended?

After I sold my Wilton (recommend but to big for me to move), I bought a Craftsman commercial. Not perfect, but does what I want it to. :)

I have that same Drill Press-I did have a problem seating it initially, but it finally did pull into place (it is a tight, tapered fit)-

Jet is a pretty good piece of equipment. It will give you a lot of years of use. As far as seating the chuck, I really can't help you too much without seeing what type of arbor it is. From what ZI am reading though the problem is the arbor into the drill chuck and not the arbor into the quill of the press. Measure the depth of the hole in the chuck and see if the arbor is not bottoming out in the chuck before it fully seats. You may have to gring the end off of the arbor a little to let it seat further down in.

I have a 10 year old Jet JPD 17MF. It worked great right out of the box. I change chucks and arbors for other things like a tapping head or larger chuck when needed, without any problems.
IMO there is a problem with the arbor to quill fit. As stated there may be a burr keeping the parts from mating properly.

Ok I got a new chuck and arbor shipped to me by Jet and I still have a wobble in the chuck. Problem must be in the machine. I drove a 2 hr round trip to the closest Menards with a press, and it happened to be a floor model. I asked to have them turn it on so I can see it run. What happened...The DAMN thing was wobbling. not as bad, but still a wobble. Jet said they would put a model together at their headquarters and ship me a working one. By the way, anyone like Grizzly's machines?

I have and older Jet drill press only 4 speeds. I picked it up at the Pomona swat meet in Calif for $40. It was missing the pinion rack and hand crank. I called Jet and told them what I had ...they didn't believe me when I described it! *G* ...That is was only a 4 speed machine. But after running down a local historian, they coughed up some suggests and got the parts ordered, they worked fine ...nice to be able to drill a straight hole once again ...definitely better then hand held drill!!! It would be nice to have more selection of speeds, and a bigger table. But for right now it fills the bill fine!
