Topic tags/keywords: drill press power tools stuck quill chuck

Ok…. I bought this Craftsman drill press off of crags list a couple of years ago. It works just fine, but it wobbles. I’m going to pick up a dial indicator to measure the wobble, but I know I need to get the chuck and spindle out.

I found the manual on line. The manual says to “Carefully tap chuck with a mallet” and the quill should fall out…. yeah, not happening. That sucker is SEIZED in there. I double checked and I did not see any retaining screws….. I knocked it as hard as I dare. I don’t want to damage it any more than it already is….

Can I get to the quill from the top, through the hole at the top of the pulleys? I’m about to try and find a shop that can do this…. Can you believe I used to be a mechanic? I can’t even do this simple job! ARGH!!!!!!

if the shaft is hollow you may be able to out a long rod down thru and tap the chuck out. It looks like the chuck is on a morse taper it should tap out once you get something solid against it.

I have a craftsman benchtop drill press as well. With mine you can go down through the shaft. I have a brass rod that is about 1/2 dia by 16 inches long. it works nice for this, down from the top, you will be surprised how easily it comes out.

I have the same DP. I also bought it on CL and the spindle was bent.

You have to remove the spring, (be careful), and remove the handle that lowers the spindle. Then the spindle is easily removed. I am happy with the DP now that the spindle is true.

I have the same DP, mine wobbles too. I was not able to remove the chunk following the instructions from the manual.
I do not have a brass rod and cannot afford to buy one. I could use a long dowel or threaded insert I presume.
I do not know why but I do not feel very comfortable to remove the spring from the side.

Tell us how you removed it. Tx

Slowly loosen the nut on the spring’s outer cover. When the tension on the nut is loosened the spring will unwind, (while still under the metal cover). Once the tension of the spring is released you can remove the spring cover completely. Then you will be able to remove the 3 prong handle from the other side. It’s been a while since I did it but I think the spindle will then drop straight down.

Caution: the spring is a coil spring and if you just pull off the cover it could unwind rapidly and cut your hand.

BJOday,

Did you buy a new spindle?

I tore it apart and cleaned all the mating surfaces. It’s better, but not right. I still need to get a dial indicator…..

Get yourself a cheap dril press drift. They work great simply an angled wedge of metal with a slot sometimes you use two opposed to each other but most times one is enough.If it is a morse taper which it almost certainly will be it should come out with a little light persuasion.definitely not a great deal of whacking it which will cause definite damage.Look up drill drift on google.Alistair

I purchased a new spindle from Sears. It cost about $50. It was delivered quickly and fit perfectly. No more wobble.

I did break the on/off switch when installing, (My own fault). They had that in stock too.

Your chuck is almost certainly pressed onto a Jacobs taper, one of the best ways to get it off is to chuck up a router bit and try using the DP as an over arm router. I’ve fixed five that had the chuck come off while trying this. The spindle is one piece that fits into the quill. If you can drop the quill out by just removing the spring, you can then press the spindle from the quill, flip it and press the spindle from the chuck with a drift or something thin enough to fit through the hole in the bottom of the chuck.

OK…. I thought I would share how this thing got blown apart and put back together…..

First, using my $5 Harbor Freight Deadblow, whack the Chuck to remove it!

Then, Loosen the retaining nuts on the crank shaft return spring

Nuts Removed

Here is the return spring, cover and backing plate

The assembly containing the hollow crank and the spindle will fall out once you remove the actual crank arm (Forgot to get a pic of this…... OOOPS)

Remove the C-Clip ring from the spindle shaft so you can remove it from the hollow crank…. try not to break it like I did

As you can see, this is NOT a morse taper! The spindle rides in two sealed bearings which in turn ride inside the hollow crank body.

I’m going to splurge and spend $30 on a dial indicator at HarborFreight. Evidently they are decent enough quality. I should be able to measure the runout on the spindle shaft itself. I don’t have a “calibrated rod” to put into the chuck, but This should tell me if the shaft itself is bent and how bad.

I ended up putting everything back together after cleaning it really well with WD-40. Its much smoother and the wobble is no where near as noticeable. But its not perfect and that will drive me bonkers.
