Question about Delta 15 - 126 Drill Presses

1 Answer

Chuck and shaft (spindle?) it was attached to fell off.

I have a 1/3 HP Drill Press Model #99-110. I was drilling into some wood and it fell out of the part it slips into. It appears to be a friction fit. Can it be pressed back into place or is there more to it? I use it for home projects and it only has about 10 hours of use over an eight year period.

    ue to the Holidays, I haven't had a chance to try it yet. The shaft that the chuck sits on is a tapered one and your suggestion that it is a friction fit and can be pressed back on would make sense although I am surprised that there is not "mechanically" secured. I'll let you know as soon as I try it. Thanks and Happy New Year!

It sounds like it is a Morse Taper. If so what you need to do is clean bith the internal and external parts with something like brake clean to remove any oil or dirt. Then wipe both with a clean paper towel. Put a block of wood on the table or if you have enough room move the table out of the way. What you want to do is seat the spindle parts and you can either tap on the chuck (make sure threads are all the way retracted) or usse the feed handle to push and put pressure to lock parts together. If you have any more questions let me know.

    Just another thought and clarification, when I typed threads I meant the chuck jaws have to be retracted and on the end of the taper shaft there is usually a flat tang. This is actually what drives the chuck and you have to align the tang with the internal socket so it will seat fully. Just push it into spindle and turn it and you will feel it lock into the socket.

How do I make the spindle chuck stay in the quill of my model FDM 16 SPC drill press? I have forced it down on a block of wood. It will stay for a while that fall out.

16 speed should have a Morse taper
for the std drill chuck

to fit a different chuck the morse taper needs to be emery sanded
and the replacement chuck should stick
after using the wood block pressure press method

if not you need a new morse taper for that spindle chuck

i had my drill accuracy and off center spin tolerance down to one thou

with stretched old belts I got more speeds than 16
for special jobs
my 16 speed used a morse taper two for the drill chuck

this picture says its a spindle chuck

Drill will not rotate

Did you have to set the chuck into the spindle, or when you got the press, was the chuck already attached to the spindle? With the drill press I got (different brand), I had to set the chuck in the spindle and I put pressure on the chuck to set it in by placing a bit in the chuck and drilling in a piece of wood, which placed pressure on the chuck. If that's not the issue, check to see that the pulleys are turning ( flip the top open). Also check the tension of the pulleys (machine OFF) If there is nothing apparent or obviuosly not working, and if the press is new, yes, I would return it.

Drill press chuck fix

The chuck on almost all drill presses is held on by friction only by use of the tapered fit you mention. Make sure both the spildle tip and the chuck hole surfaces are completely clean and dry. Set your table so when you move the spindle down it will contact the table. With the drill OFF, put the chuck on the spindle and press it down on with the table as hard as you can without bending any handles or gears. This should be sufficient to hold it in place.

Fleetwood 50 drill press chuck connects to the spindle how?

The chuck on 99% of the drill presses is just a press fit. The end of the spindle where the chuck goes on is slightly tapered to hold it on. Make sure the end of the spindle and inside surface of the chuck are very clean. With the motor off, raise the table high enough so you can still get the chuck on the spindle then turn the handle to lower the chuck against the table and press it firmly against the table to wedge the spindle in the chuck. There shouldn't be any need for anything more than this.

I have a Guardina Power 5 speed heavy duty drill press, model number DP-MINI 1/2 inch chuck. The chuck will not stay on the spindle. There doesn't seem to be any set screw, threads or any type of method...

The chuck is held in by the tapered shaft and friction. Make sure the tapered shaft on the chuck is clean with no burrs. Do the same for the socket side in the spindle. Swing the table out of the way and set a wood block under the chuck. Bring the spindle/chuck down into the block quite firmly which should lock the two tapered parts together. Hope this helps as it worked on my drill press!

Drill press

No there isnt. the chuck has a taper fit and needs to be cleaned and installed correctly. Use something like a brake clean or carb cleaner and spray the shaft and the internal socket of the chuck, wipe both clean with a paper towel and then move the table out of the way and with the chuck jaws fully retracted use a piece of wood and "seat the chuck" I usually strike the wood a couple of times. this should work as long as the tapers are not that worn.

The spindle with the chuck attached keeps falling out of my drill press. I can push the spindle (arbor shaft) up into the machine, but it later falls down. How do I fix this?

get something like brake clean and spray both parts the shaft and internal socket and then wipe with a paper towel. Next put the shaft into the socket and "tap" into place with a block of wood on the drill chuck with the jaws retracted. You might have to "tap" a little hard if you know what I mean but this will seat the tapers and you should not have a problem for a while.

Chuck & shaft fell out of spindle drive

is the shaft a taper, if so clean it with brake clean or equivelant and wipe dry with a paper towel and use a block of wood with the chuck jaws retracted to tap the spindle back into the drive. It should lock back in place, it is just a taper socket fit.

Help with drillpress?

Yes the tapered shaft holds the chuck on. Assuming that there isn't a hole for a set screw you would 1. open the jaws of the chuck all the way, making sure they are completely recessed 2. seat the chuck on the drill press spindle/shaft as far as it will go 3. place a piece of wood (2x4) against the chuck 4. carefully drive the chuck onto the spindle by tapping the block of wood with a hammer until it is fully seated. Don't tap the chuck with a steel hammer directly, use a block of wood. Hope this helps you. Good luck

The chuck has come off my delta desktop drill press. nothing i can do will get it to stay on.

clean the spindle and the inside of the chuck with easy off oven cleaner. get it all very clean and then be sure to remove all of the debris. pound the chuck onto the spindle with either a rubber mallet or put a block of wood under the chuck and use a regular hammer. DO NOT hit the chuck directly with a steel hammer.
