Wobbling bit in DP

[PostalBob]

OK Been putting this off for some time so decided have no choice well I do but get better result on here vs talking to Delta Have new 16 inch Drill Press, from the very beginging it has never really drilled straight, did the entire trouble shoot thing A to Z. Cleaned the qill did it all, and still when I insert a drill bit i still get a wobble end drill, not serious but enought to make me wonder what is wrong?
Took it apart per instruction and tried to find some fault, did not.
When I put it back still seems wobbly, Point to make if I hold onto the drill bit at the end I still get some movement, minor but still feel some movement left and right, also if I hold onto the bit I can push it up and into the quill and feel some sort of movement on the drill bit.
Dont want to go down that road with Delta, before I am really sure what I thik is wrong? Only been doing this great hobby for a little over a year and I like to think I have learned a lot, from fellow club memebers and reading all that is available here on line.

Any quick thoughts on this or do I really need to go to Delta and start my begging for help.
Reason I say this, was. Last drill I had major problems and they ran me all over the country side trying to get it fixed, end result was great manager at Lowes saw my problem and took it back even after 90 days.
Decided to buy a bigger one right there on the spot.

OK if you will, like to hear some suggestion on just what you think might be a problem? Or can it be corrected or returned?
Thanks
Just wated to say in the year that I have been turning I cant say enought about this great site, I try to resd and watch as much information that is on here and have learned a great deal in that period. Thanks to all

Most likely your chuck is not well seated, a speck will affect it...

Remove chuck and very lightly, (same pressure you would use on your finger nails)with a piece of 400 grit Carborundum Paper, (Black, Wet/Dry) clean off spindle taper. Then wrap paper around dowel and lightly clean inside chuck taper.

The chuck is a friction fit, now move dp table, hold chuck in place and with a solid swing with a rubber mallet, seat the chuck.

Sometimes it takes a couple blows to get it seated properly...

If you believe you have eliminated all external problems, the drill press may be defective. Sometimes (also applies to lathes) when the Morse taper hole is drilled and reamed it is off slightly from perfect center. Any wobble is unacceptable. Do contact Delta and go through the hoops to get replacement if you determine it is a product defect. Good luck.

Thanks for your input, Will give it a try and also have contacted Delta and awaiting for a reply, was hopping that i did have to go throught this but i think I will be returning it, Talked to Mgs at Lowes he said should be no problem,?? Will see. Again thanks for your input.
Will keep you advised.
Thanks

John,
I have tried several times to figure out how to get my Delta drill press chuck off with no luck.
How does the chuck come off?

 

[jwoodwright]

Ron, this is a S.W.A.G. as I don't know what Delta you have...

There are two methods, 1st has a drift key. This fits in a slot in the quill and forces the chuck out. It's a piece of flat stock, 3/8" thick; tapers from 1/4" to 1"...

2nd is the 3 hand method, hold a piece of 3/4" X 1' Oak, using hammer of your choice, strike top of chuck, catch chuck with 3rd hand...

Box of sawdust on the dp table can be used in place of 3rd hand...

Bob, my first suspicion would be the drill chuck. Chuck up a (metal) dowel pin or something similar and check the runout with an indicator. Remove the chuck and and indicate the quill bore for runout. That should show you where the problem is. DUH, my bad...if you have an indicator you already done that!

Without an indicator, position a stationary object next to the pin, and rotate the quill. Runout will be easy to see. If the pin runs out it could be the chuck or the drill press quill itself (unlikely though). If the pin runs true, your drill is bad. To further check the drill chuck, remove it from the drill press and put it in your lathe, again closely eye the dowel pin. Real good drill chucks can be found reasonably on ebay. I like the "Jacobs Ball Bearing Super Chuck". Due to clearance needed for quill travel, a drill press spindle will have a slight amount of "play". Should only be a couple thousandths at the top of the chuck...further away from from the drill press head the "play" will be exaggerated.

I did what Jeff is suggesting with my 30 year old Black and Decker DP. It turned out to be no more than 00.5 (a half a thou.) off at the base of the chuck. I was very pleased with this result. A friend gave me another old DP and it turned out to be less than a thou off as well.
My point being, don't accept any less from a "new" DP. Especially a Delta when they are supposed to be one of the better tools on the market.
I wouldn't accept any more than a thou at the chuck, if that.
Just my 2 cents.

P.S. these are both bench top models, I would expect better from a stand up.
