I just bought a bench model dp220 and my spindle has the 1/2 - 20 LEFT hand threads and the chuck is missing . Does anyone know where I can get one . I found some but they say right hand thread . I would like to put a 1/2 " chuck on it . I also need the spring return mechanism for the quill return ( spring and housing ) , I found one on ebay for $20 but I'm wondering if that's a good price or not . I kind of think that return isn't a big deal but the chuck is . Thanks.

Sorry, but DP220 is just a tad bit obscure. I don't think anyone here has all model No's memorized for every DP MFG, so the only person likely to recognize the No. is someone that happens to own it?
And for any question of this sort:
And for any question of this sort:
mine is about the same as the one in this thread http://www.garagejournal.com/forum/showthread.php?t=115842 , but I don't know if that's all that important , I'm just trying to find a 1/2" capacity drill chuck that has a 1/2 - 20 left hand threaded hole in the back to screw onto the 1/2 - 20 left hand threads on the end of my spindle .

Any good machine shop supply company can order you one. They are odd and 20 years ago they were $75. It was a Jacobs.
Look one up on the web and hold on to your pocket book.
Jacobs and several German brands are the only ones that are worth buying. Some Japanese ones are very good as well. Your drill press must be form 1935 to about 1960. The old ones had threaded chucks. I always pull the spindle and grind a taper on the end then just pop a spare chuck on. I did not want to spend the money on a new chuck because it always was many times more than I paid for the press.
I have a small machine shop and don't need to send anything out for grinding.
The last drillpress I had that took a special tapered chuck I sold for $100 without the bad chuck. The person was very happy to get the cheap import well used drill press for $100. That was until he found the Chuck and belt were going to cost him another $100. LOL
I got a lift cart with the drill press. It cranks up and cost about $600 new. I wannted the cart. I paid $100 for both and ended up getting the cart free. The press had no run out which supprised me. Who said Tawin makes junk. Not me.

Sounds like someone modified your spindle. OEM on the old Delta 14" drill presses with the DP-220 head casting was a #33 Jacobs taper (33JT), not a threaded spindle.
EDIT:
If your drill press is as old as the one in the link you posted, your spindle may be the original "Delta-Grip" chuck spindle, minus the chuck. Those chucks were integral to the spindle, not simply threaded on, and I'm not certain the spindle was a standard 1/2"-20 LH thread. They weren't meant to be removed from the spindle. In any case, if it is the Delta-Grip spindle, and is still the original length, it will be too long for a replacement chuck to fit well.
Here's a cutaway view of the orginal Delta-Grip chuck used for a few years on early 1930s-vintage Delta drill presses:
We need a photo of your drill press and spindle.
For the quill return spring on the pinion, yes, $20 is a good price assuming the spring is in good shape. Just finding one at any price in that vicinity is good.

I'm new to posting pics on this forum so I will try it . One photo is the drill press and one is a closer view of the threaded spindle , but it is kind of hard to see that it actually is threaded , and the pdf file is the manual for one that is either my model or one like it . I believe the manual and my press are from the '30s . The manual has the prints showing the threaded spindle . I can't get the manual to upload , only the photos I think .

Yes, that's the Delta-Grip chuck spindle, and your drill press is roughly from 1936 or 1937. Somebody removed the Delta-Grip chuck body, probably because it wasn't working. Those chucks had a relatively-soft steel sleeve and were all too easily deformed by the chuck jaws, after which they wouldn't run true anymore.
As a result, they replaced that chuck and spindle style with a standard #33JT nose spindle and a #33JT keyed Jacobs chuck.
Here's what your chuck was originally, on the left, and the Delta #970 replacement spindle with #33JT nose on the right:
As I mentioned in the previous post, the thread on your spindle may not be exactly the same as a 1/2"-20 LH thread, but in any case, it's too long to mount a threaded chuck on it, especially with the extra stub at the end.
Cat. No. 970 Delta spindles with the 33JT nose come up on eBay quite often, usually with a chuck included. That would be your best bet IMO.
You can easily remove your existing spindle. Just lower the quill until you can see the collar at the top of it in the opening in the head casting. Lock the quill. Loosen the set-screw on the collar, and the spindle will slide out of the quill. However, before sliding the spindle out, lift the collar up, and if you see a dimple in the spindle (from the set-screw point), remove the whole quill assembly instead, so you can get to the dimple on the spindle to clean it up with a file before sliding the spindle out. Otherwise, that dimple can make it hard to slide slide the spindle through the bearing bores in the quill.

Thanks . I saw a spindle on ebay but I'm not sure what it was . I think the same spindle fits many different years ???? Is that correct ? Yes I knew from the prints that the end was working with the delta keyless chuck . I don't know how deep a newer chuck is tapped . It did have a nut and a thick washer that were both screwed onto the threads so I just figured the nut was a 1/2 - 20 left hand thread nut ??? I also thought of cutting some of the threads off so the chuk is closer to the quill ? Thanks for the info , I'll look for spindles .
The Cat. No. 970 spindle fits all 14" Delta drill presses made between 1932 and 1953. It also fits the old 11" Homecraft drill presses, Homecraft 11-280 radial drill presses, and the very short-lived Delta 11" drill presses made around 1940-41. It doesn't fit the very old Delta #620 drill presses, nor will spindles from the #620 fit the 14" drill presses (different lengths, respectively).
You may be able to modify the threaded end if it is 1/2"-20 LH so you can screw a threaded chuck onto it. You'd need to check the thread with a thread pitch gage and a micrometer or dial caliper to see exactly what it is. The threaded chucks are sometimes threaded all the way into the chuck body, but not as far as the length of the old Delta-Grip chuck spindles.
