Delta dp220 drill press help

I have one that seems to have a bent shaft. I'm trying to locate one with not much luck but did see one on eBay. My question is mine appears to have a thread shaft wear the chuck goes on and the one I found does not. Can there be 2 versions of the same item number? Any idea of other places that may have what I need? Thanks

Can you post a picture? I don't think DP290 is a model, but more so a part number.

When you say "shaft" are you talking about the spindle? How bad is it bent? I think what you have is a DP220, which is a 14" machine. They made a few different spindle options for it.

I'll have to get pics tomorrow but it has dp290 stamped in casing under Delta which is why I assumed it but you may be right. Yes I'm talking about the spindle it's enough wobble that you can drill and an accurate size whole. When I googled it the same pics came up under dp290 as what I have also.

IIRC, the "DP290" is the casting number for the motor mount plate on a standard 14" Delta DP.

And yes, there were at least six different spindles for the 14" Delta., including JT33, #2MT, 1/2" straight, threaded.

Before you give up on that original spindle, you may be able to straighten it on the bench. Place a hardwood piece at each end and rotate the shaft to find the high spot. Another hardwood piece and a hammer at that point, if you work carefully, can put it straight again. Roll it on a flat table when it looks good. Have used that method many times and you'd be surprised how close you can get it.


............what do you have to loose? Of course there are more precise methods but they cost more too. Probably more than a used one....if you can find one.

I had to straighten mine when I rebuilt my C150. Here's a guide I found - http://www.rvplane.com/pdf/drill_press_tune-up.pdf

I found it more effective to hold a 1ft chunk of 2x4 against the rod chucked into the DP and hit it with a big hammer rather than hit the rod directly. My initial run-out was about a 10th of an inch, I got it down to about 5 thousandths

I used a 1/2" grade 8 bolt for the rod. Don't even try without a dial indicator... HF has a kit with a dial indicator and and adjustable arm for about $30.

How do i tell which I have?

Yea I already started working on that part but I'd like to see if I can find another as well as a few odds and ends.

X2 on straightening it before disassembly/replacement, do it all the time.

Well I worked on it for about 2 hrs and have very little change in it if at all. I can tell its in the threads though from when I remove the chuck you can just watch it wobble while its being threaded on. Ill see what the machine shop says about fixing it or if the even can.

If it were mine, I'd consider just buying another spindle. They're out there - sometimes cheap, sometimes not. I've bought a whole drill press for what some of the eBay/OWWM sellers were asking for a spindle.

For a typical home shop DP, a spindle with a Jacobs Taper #33 is probably the most common and useful. Try to find one with a good chuck and key already on it.

I've checked by part number for one with no luck. How else can I search for one to make it easier or to expand my search?

 

[188slo50]

It's dropped off at machine shop but they weren't to sure if they could fix it. Any ideas of we're else I can find a shaft at?

Have you signed up over at Old Woodworking Machines?

Someone there will definitely have a spindle. All it takes is money.

Yea I signed up a few days ago just waiting for approval for forum membership.

Well I heard back from the machine shop and apparently it's not bent when delta made it they the cut the threads correctly on the shaft. The threads are cut offset causing the wobble. Looks like either I find me another or spend $150 to have it redone.

 

[zkling]

I will ask again, can you post a picture of it on here?

 

[jakemac]

Is it too late for warranty replacement ?

 

[188slo50]

Of the shaft or press? It's tore all apart and in pieces at the moment.
