I've picked up a decent Delta table top model drill press for small work , nice condition albeit missing the clock spring ....ugh .

Need to figure out what the age is and any specifics I can get about it . The old girl is nice and tight except quite a lot of runout at the chuck as it's worn . I'd guess it spent it's life doing wood or something all other things considered .

Looks like the clock spring cap diameter would be about 2-1/4" with two 5/16" locking slots . Shaft is 1/2" diameter with a slot for the spring itself .

I've seen a few for sale on the 'net , but no real dimensions and I'm curious if there were any changes made over the years ??

Your 14" DP an early version. Technically, the DP 220 is the head casting number. The switch, motor and mounting bracket are not original. As to whether there were changes in the return spring, those over on the Vintage Machinery site http://www.owwm.org/ are keepers of such minutiae and if you have the serial number, they can give you the production date. Before you join, read their numbered rules. There are many and they are strict in their policing thereof.

FWIW, it appears your DP may have one of the optional spindles; possibly the 1/2"ID for use with mortising chisels. Delta made a half-dozen quickly interchangeable spindles; JT33, MT2, 1/2"ID, threaded, et al. I prefer the JT33 for all-around use, so you might also be on the search for one of those.

I will have to be careful to stay in good stead. I joined to get information for a part I could not find and would need to fabricate. A member was kind enough to measure his from every possible direction to make sure I got it right. They had my owner's manual, as well. They are a great resource.

The 3 main rules they are very strict about are don't ask what something is worth, don't ask about Asian made machines, and don't mention current Ebay or CL ads. Lots of good info there though.

I gave up on that group a long time ago. A small clique of people run it, and if you're not in that crowd, you're nothing.
I asked why something couldn't be done a different way and the reply included "I don't give a rosy red rats *** what you think".

I don't need people like that.

You can still access the machine pictures and information at Old Woodworking Machines.

The following was more than 15000 characters long and the limit here is 10,000, so some had to be cut, but you get the idea.

Old WoodWorking Machines Forum Rules:

Your OWWM Membership:
Your membership here is a privilege and not a right. As a member you agree to abide by all the rules of the OWWM Forums. Your membership can be temporarily suspended or revoked at any time for any reason as determined by the site administrators. Excessive rule breaking or egregious offenses will result in a full banning.

Religion:
Do not post about religion.

Politics:
Do not post about politics.

***:
Do not post about ***.

Divisive Topics:
Do not post topics that push people’s buttons. Remember, not everyone shares your opinions. If in doubt forward your text to a moderator for review.

Respect:
No member will berate, belittle, bad mouth, criticize, decry, depreciate, deride, derogate, denigrate, diminish, discount, discredit, disparage, dispraise, downgrade, downplay, dump on, flame, knock, lower, minimize, pan, poo-poo, poor mouth, put down, rap, rip, roast, run down, scoff at, scorch, scorn, slam, smear, sneer at, take down, tear down, underestimate, underrate, under value or write off any member or their machines.

Online Auction:

Craig’s List & Classified Ads:
Do not post a link to, description of, or allude to any Craig’s List or classified ads. The only exception to this rule is when it is mentioned as the source for a machine you have bought.

Disputes:
Do not air your dirty laundry here.

Cross Posting:
Do not cross post (same topic to multiple forums).

Appraisals:
Do not ask for or give appraisals. Without seeing a machine in person, there are too many unknowns. In addition, prices vary considerably by location, condition, age, ease of pick up or delivery, and so on. Your best option is to search for available sale prices, such as completed sales on eBay (as opposed to listing prices with no bids), listings on our own "Bring Out Your Dead" forum, and other sale sites.

Vulturing:
Do not ask someone to part out a machine.

Chumming:
Do not advertise a sale on any forum other than Bring Out Your Dead.

Rants:
Do not post rants.

Loop Holes:
Do not explore loop holes to get around any rules listed here.

Asian Made Machines:
Asking for information, offering information, advice or the discussion of Asian made machines is not allowed on any forums.

Electrical Topics:
Discussion of permanently installed building wiring systems is not allowed. This includes service entrance conductors, panel boards, circuit breakers, branch circuits, and any portion of branch circuits leading to and including a receptacle (outlet) or disconnecting means, otherwise known as permanently installed electrical work.

Allowable electrical topics include wiring within an old woodworking machine, including the motor(s) and controls. Discussion of RPC or VFD wiring is allowed, but only insofar as it pertains to the devices themselves, or control of the devices, not the portion dealing with supply wiring, circuit breakers, branch circuits, receptacles, nor any other part normally associated with permanently installed building wiring systems.

Avatars:
Avatars must contain clear and recognizable OWWM content. Animated avatars are not allowed. Avatars found to be offensive or non-compliant will be removed at the sole discretion of the administrator. Do not re-use an avatar after it has been removed. If you find your avatar has been removed and have not been alerted to this by an administrator please contact an administrator (use the PM button below).

Off Topic:
Do not go off topic for the forum you are posting to.

Bad Advice:
In the event that you see dangerous or harmful advice given on these forums it is your responsibility to flag the post (triangular button with the exclamation (!) mark) to make a moderator or administrator aware of the posting. Members who post dangerous or harmful advice will be contacted by an administrator and told to stop. Failure to stop these postings will result in removal as a member. This removal will be without recourse.

Compliance:
In the event that you are unsure of compliance contact a moderator or administrator. The adage, “better to ask forgiveness than permission”, doesn’t apply here.

The Old Woodworking Machine Forums:
What follows are brief descriptions of the Old WoodWorking Machine forums and their purpose. Additional rules that directly apply to these forums are listed with that forums description.

Old Woodworking Machines:
This forum is for the discussion of Old WoodWorking Machines. OWWM is defined as any machine that is twenty years old, or older, or a machine that is no longer manufactured.

Allowed topics include those about machines, machine repair and restoration, machine parts, machine set-up, machine maintenance, paper, machine or company history and memorabilia specifically related to OWWM. Additional allowed topics include discussions of tools or machines used in a specific repair and/or restoration of an OWWM.

Discussions of old woodworking portable power tools are also allowed.

Bring Out Your Dead (BOYD):
The BOYD rules are posted on the BOYD forums.

SWARF Forum:
The SWARF (Stuff Without Arn Related Facts) Forum is for the discussion of anything you want as long as you follow the rules (see all the above).

Behavior:
SWARF is not a wild west show.

Craig’s List Exception:
While it was once OK to discuss certain Craig’s List ads that privilege no longer exists.

OWWM.org Support Forum:
This forum is for members to use when having problems with the discussion forum like logging in, how to navigate the forums, changing their profiles, practicing their hand at posting pictures, etc. Please note that you do not need to be logged in to post to this forum so members can, if they are having problems with logging in, post their problems here. Typically this will result in faster action than e-mailing or PMing a moderator or administrator.

Why We Have The eBay (Online) Auction Rule:
Online auctions create a level playing field where we all have the same advantage. If a member finds an auction they don’t want it exposed to the world. Put another way, would you alert the group to an auction you had an interest in? Think of it like a fisherman giving out maps to his best fishing hole.

The usual reason given for violating or wanting to violate the rule is that the violator/potential violator feels that the item will go for under what an OWWM member would be willing to give or the item will be lost to a non-member. With the former it’s pretty unlikely that another member hasn’t already seen it. With the latter, that’s life and no one has yet decreed that all good deals should go to an OWWM forum member.

Professing a misunderstanding of a rule or a disagreement with a rule will not be tolerated. Remember, thousands of members understand, follow and do not challenge the rules.

When Can an Online Auction Be Discussed:
When an online auction is completed/finished it can be discussed. Keep in mind that pictures from the auction will more than likely become dead after a given time and if you insist on discussing the item you really should take the time to repost the pictures to a site like Photo Bucket or Image Shack where they can live on with the post. If your inquiry is of a historical nature and should be archived please post it to the Old Woodworking Machines forum. Please note that most online auctions sites have changed the way old (completed) auctions are displayed and that current auctions are displayed along side the finished auctions. Links with these current auctions displayed will be removed.

In the event that you find yourself needing information prior to bidding on an online auction it is up to you to devise a way of asking your questions without exposing the online auction.

And when all else fails, send a Private Message (PM) to a moderator or administrator. You might be surprised what the outcome will be when you ask first.

What Happens When the Rules Are Violated?;
A violation of any of the rules will cause the forum administrators and moderators to believe that you’ve not read the rules (not an excuse), don’t feel the rules apply to you (you aren’t that special to anyone but your mother or your dog) or are making a blatant attempt to challenge the rule(s) and/or the forum moderators and administrators (not a good idea). The moderators and administrators of the forum reserve the right to deactivate your membership on the spot without warning or recourse. This dismissal may be temporary or permanent.

While no one is expected to agree with all the rules laid out above, all are expected to follow them. If you have a question about a rule or would like a clarification please feel free to contact an administrator. If, for any, reason you feel that you cannot follow the rules as outlined above please contact an administrator and ask to be removed as a member of the OWWM forums.

By your staying here after the published date of these rules it is understood by the administrators that you have agreed to abide by these rules.

Yeah - I've seen that board and looked at some of their pics for a short time and have heard how they treat their members . I don't usually ask simple questions anywhere as I know better and understand if you don't at least do the basic research leg work you don't belong . Newbie stuff only goes so far and some places it's not tolerated at all . Dictator-run sites are off my list of places to visit , they can keep to themselves .

@454ragtop - if you have a clock spring/cover I'd be interested - let me know or I can send a pm . I'm usually pretty good at finding parts and doing research but this thing has very little details out there .

That chuck adapter is a problem and doesn't appear to fit tightly - need to get time and investigate it further . If it's a straight shank type I'll swap it out for a taper style in JT33 or something .

I see no hints of a serial number anywhere on this machine , unless there was a stamped tag on it at one time - nothing now and no other numbers except the cast model numbers . I suspected it was an early version and glad to confirm that . I assume probably 1940's..?

BTW - I don't visit here often but appreciate the info and have found a lot of good tech writeups and photos with details about tearing machines down and doing repairs - not many places to get that info anymore . Also , the threads generated about what equipment is worth buying are also great and the opinions here are very honest and non-biased - that is rare these days with so much being driven by sponsored advertising .
Nice to have a basic forum to discuss all things that can mangle your fingers , lol ...

I also gave up on OWWM. The guy who runs it is a nut job and has other nut jobs as moderators.

My experiences over there have been the exact opposite.

Members there have given me some excellent help on my DP-600 project including some excellent spindle disassembly images and dimensions on foot pedal linkage that I had to fabricate.

One member even sold me a super scarce cast foot feed pedal at a nominal cost. That's something that could have taken many years to find.

I think the key to a good experience at that site is to do your homework first (ie search), then ask specific questions and include images. A picture is worth 1000 words. I don't see why a moderator would hassle you if you follow the rules. They're kind of a tight knit community but there's a lot of expertise and they seem eager to help.

My experiences were the same as Roberts210. I know a little about old machinery, and try to post useful things - not stupid stuff. I let the first run in with the mod pass figuring he was just having a bad day. When it happened again, I left.

Yes, the ordinary members there are very good people. I was also helped by a member there, and given a piece for my arbor press. The members there are great--the bully who runs it... not so great.

I have a circa 1952 I think Delta DP220. It works fine but now it's an extra in my inventory. The clockspring is a bit sluggish but got better when I cleaned things up. Some people here have added a 3rd middle pulley to lower the rpm.

Mine has the full cowl belt cover. It looks like Mother Predator from the movie series.

A guy on Popular Mechanics turned his into a milling machine not long ago. I think he did a CNC conversion.

I have a floor model that is about the same age as driftpin (IIRC, mine is '51, last year the tag read Delta Milwaukee). Same full belt cover, which are apparently pretty rare. There has been one floating around on e-prey for about $200, no bites, but nothing for the 3-4 months before that.

My unit has an aftermarket switch mostly over the red label on the head, so I cannot see exactly what it says. I might get interested enough in it to remove the switch and take a couple of pics, and file them for future reference.

It does have a Westinghouse motor which can be run CW or CCW which is I believe a function of a split-phase motor. It can also be wired to run 110/220 volts, 1725 RPM, 1/3 HP. The motor mount plate looks to be original to the machine, and it appears that just by substituting a taller 2-3/4" head and table shaft, you could make it floor-standing, though the base may be a bit small, and would probably benefit from either being bolted to the floor, or having a plate offering a larger footprint attached to the stock base.

I've seen some pretty wild conversions done on some of these old vintage machines - amazing what some folks can come up with . Never a CNC DP-220, though..lol .

I may just make a new spring and cover - the machine is only for light work and I'm hunting a heavy 20" or so unit to replace the current 17" POS Craftsman that I have . More runout than a Model T on that thing and I'm not replacing the wobbling spindle again . Light jam on one tapered bit in it and it's done...way too lightly built and no decent tolerances .

I need a mill , really - just don't have the room if you look at the pics of the shop I'm stuck with right now .

Appreciate all the feedback , wish the dumb serial plate was still on it but it really doesn't matter when it was made - it's good and tight yet and totally repairable and will suit what I wanted it for nicely .

Bad idea to try to use one of those for milling. The spindle is not designed for side loads like a real milling machine. Usually what happens is the chuck wiggles loose and falls off.

Absolutely a bad idea to put a milling cutter in a drill press Jacobs chuck or #2MT chuck, then put a steel workpiece in a Chicom X/Y table and try milling. Very dangerous things will happen.

I looked at OWWM.net, info there says my DP220 is a 1944 model. It says it's from the Milwaukee-Crescent timeframe, the narrow riveted-on red background "Ser No" plate says, 30-9XXX.

The front pulley is about the same dia as the rear, both are v-belt, 4 channels, and a nominal 5-1/8" in dia. The front pulley size leads me to believe this is the 'slow-speed' pulley.

The machine has a stamped-steel handy-box bolted to the right side (as you face the worktable) containing a new modern switch. I hope this info may help someone.

I have stored the article on the work this guy did to his DP220 to make it into something it apparently was never intended to be. I'll locate it and post the location of the article, or perhaps see if I can upload it.

Pretty sure that is the high speed pulley, think the low speed is 7"+ in dia. I'll check when I go out to my shop.

It may be, I was poking around here & on the OWWM, 'lurking,' (not a member) and saw the spindle high speed pulley was quite a bit smaller in dia, if I read the post correctly.

All this talk, I went out & flappered my work platform, no many-divot 'arc of shame,' but it does have some blemishes. I did re-insert the depth indicator correctly, and wire-wheeled the chuck to see it's a jacobs 6A.

I have a 'sister' Delta piece, an 8" iron/steel cabinet table saw, guessing it's from the 1950's, the table & wings are cast iron, "made in Milwaukee" but I haven't researched the serial # to see when it was made. It's a cute piece, I had made some thick-wall rip fence mounting tubes for it years-ago, but I've misplaced the mounting pins and the spacers, I should post a 'wants' ad for that. I've had it in storage for years. I bought it probably 35 years ago, when a local water bottling plant was bought-out by Pepsico ("Syfo" in Miami FL, the brand is still used) and I went to the shop closing. It was the only piece of equipment I could afford.

Pretty sure that is the high speed pulley, think the low speed is 7"+ in dia. I'll check when I go out to my shop.

I read the long version of the rules, that someone posted. Nothing struck me as unreasonable. Some other sites could benefit; especially the parts about insulting people and staying on topic or enless discussions about whether something on CL is worth the price. I confess to being guilty of those on occassion.

Somebody has a video addressing those problems on an HF dp conversion. They replaced the bearings with ones designed to take a side load and found a way to keep the chuck on with some parts replacement and some machining. A lot of us could use something like this for occassional milling. I know there are still issues with rigidity and vertical adjustment but at least the chuck won't fly off.

I have no experience with this drill press but is normal to only have a single step motor pulley? If you change speeds isn't the belt at a terrible angle to the pulleys? Am I seeing this wrong?

My spindle and motor pulleys are both 4 steps.

I found something interesting today while moving the DP & it was a foundry date cast-into the work platform bottom. Now I know the OWWM website data for date of manufacture is accurate going by the serial #. I found that my table and I assume the entire unit was made in 1944 during the Battle of the Bulge because it reads, "11-8-44" which is pretty cool. While we were half a year from V-E Day, Delta built this as a tool to probably take its place somewhere in America building tools of war. :rocker::bowdown::rocketwho

5-1/8" is the high speed pulley, low speed measures about 7-3/8" at the widest point.

Great research. With almost everything devoted to the war effort it probably did it's part. I had that feeling when I went to an air show at Republic airport on Long Island, N Y. and saw a P47 Thunderbolt. That plane was most probably produced where the factory had been, next to the field and flew from that field for the first time.
5-1/8" is the high speed pulley, low speed measures about 7-3/8" at the widest point.

You're still going to need an intermediate pulley setup to get the speed down slow enough for most metal drilling.

Can you do that with the pole where it is? Do you have to go to the top of the pole to have an intermediate pulley?

The head should be raised to the top of the column.

This is an old Delta drill press (my Dad bought it new in 1938) but the intermediate pulley set-up...







...should be the same I would think. I hope that helps.

The OWWM.org rules ARE somewhat constricting. Obviously none of us like being told what to do (or how to do it). I have found that I can abide by their rules if I keep in mind that the people who frequent there are really great people, and their knowledge about these old machines is incredible. This is a superb resource for those of us who want to restore old machines but don't have the experience to "just do it". I have restored several machines and I owe 99% of my success to the guys (& gals) at OWWM. They make it worth tolerating the rules.

Oh, and here is my DP 220, awaiting restoration...

Your handle is the same style my 1944 model has. If you have spare belt covers, there are people on here who are looking for parts, as one has contacted me. Looks like the head spindle cover is differently-colored from one pic to the next (grey vs. green) which is what I saw.

BB767 -
Those photos are exactly what I have in mind to make an idler setup - shouldn't too tough to make a clamp/mount to fit the top of the column post , an idler bearing/pulley mounted to that and away we go...if it can swing to snug both belts , even better.

I just sold my Delta DP220 yesterday and am trying to interest him in my Delta 1950's vintage cabinet saw.

Before I gave it to him, I had to easy-out one of the belt tensioning screws whose head snapped-off last time I tensioned the blade after making a belt speed adjustment. For safety, I replaced both screws while I was at it.

I have been looking further into the return springs and knob parts...

It seems that almost all the older models there is no difference as long as the spring cover is the same diameter - is that correct ??

I found a nice spring/cover - turns out the pinion shaft had been cut off and shortened ....probably a broken spring and someone mangled the end of it where the locking nuts sit . So...waiting on another pinion shaft now...grr.

Still working on the Clausing as well , not sure which one will win the race but one has to get in service like last week....

Pinion shaft installed as well as spring , waiting on some 7/16" hardened drill rod to make the handle . Got everything lubed up adjusted , nice and tight with no slop or drag . Gotta love old equipment .

Not impressed with the 1/2" straight shaft chuck mount - this one is either bent slightly or just wasn't made very well at the chuck section . Need to research into what spindle shafts were available for this model ...

Anyone have an idea of a submodel number that would fit this machine ? Seems there are several part numbers for bench type DP220's....
