Drill press problem

[turbo6justin]

Picture should explain it pretty well, my question is is it the chuck falling off the arbor or the arbor falling out of the quill? And what the heck do I do about it?

Happened while drilling a 7/8 hole with a freshly sharpened (not by me) bit but something was definitly not ground right as it was vibrating like crazy and making little itty bitty chips/slivers. I only had to do 2 holes and got through it but now what did I break.

Missing or loose shaft collar on the spindle shaft.
It is a round collar with a set screw.

Pull the quill out and take a look.

Alright that sounds easy but I am lost. I can get the piece (spindle) that is hanging down back up into position if I spend a little time getting it to line up with whatever is in there as I push it up. It will go up till it just pokes through the spindle side pulley which is where it used to rest.

I cannot get it to come out any further than it is in that picture though. I probably won't work on it more till tomorrow but where about would a shaft collar be in there? (Yes I know what that should look like) It is an old cast body so access is a little difficult.

I have the same drill press.
I don't have a good picture of what i am talking about.

What you need to do is lock the quill in the up position with the lever on the left side as you face the press (Looking at it in your picture).
Release the spring pressure for the quill return on the left side by loosening the bolt under the spring knob while holding the spring knob. Slowly let the spring pressure off.

Loosen the bolt on the right side of the housing that holds the pinion. This is connected to your handle assembly that lowers the quill. Carefully pull the entire handle assembly and pinion out of the housing.

Now you will be able to remove the quill. Hold the quill with your right hand while you loosen the quill lock you tightened in my first step. Now the quill will pull out of the bottom of the housing.


The first thing to go down the spindle shaft is the shaft collar. The set screw will go into a hole in the spindle shaft.

Edit: you will also need to remove those 2 jam nuts on the depth stop. These nuts are what stops the quill at a certain depth in your work. I see them on the right side of your picture and they are currently about 3/4" apart.

good luck.

I just stole this picture from another thread.

The shaft collar is on the left side of the spindle/quill assembly. The set screw is visible.

Believe it or not that made perfect sense. I am sure the second I touch it everything will go blank in my mind and it will not come apart that easy but it all makes sense. The picture is great.

I have taken damn near everything else I can think of apart but a dril press is not one of them.

Thanks again.

Just to wrap this up a little, it is all back together and it's working fine. The above advice was very helpfull if anyone else finds this in the future. I was able to get it back together without taking the whole spindle off. I took the tension off the spindle return spring and removed the spindle lock. Then reaching in from the top and bottom was able to get everything back where it was suppose to be. My collar was intact and just spit the set screw. Unbelieveably I found mine but in my case it was 5/16 with a pointed end (not flat) if you need a new set screw.

Pretty straightforward, many thanks to Alan!
