Hi all, new member here, I have received an old drill press that used to belong to my great uncle who passed in the 70's. It's missing some things and I was wondering where is the best place to get info and or parts to refurbish this thing. Thanks for any info!
Rockwell DP 220 Drill Press info

- Start date
I'd suggest checking out the Vintage Machinery site: http://vintagemachinery.org/mfgIndex/detail.aspx?id=1141&tab=3
BTW, I believe "DP220" is a part or casting number, not the model no. for that press.

Every part you will ever need will be on Ebay.

Look under the table and report what is the date cast-into the bottom of it.
You're missing the belt guard which makes it look like the mother alien in the movie, Alien.
If you search on here you will find lots of posts and threads about this particular drill. There is even one where multiple drills are ganged-together to drill holes on a production line simultaneously. Pics included, it was found at a surplus auction.
You will also discover how-to slow it down for drilling steel.

Looks pretty complete to me! You might want the 3 spoke wheel for it. They aren't too pricey and add a lot of functionality to the press. Also maybe look at some pics for ideas on the switch rod and mount. The biggest thing will be the bearings so hopefully they are good enough to repack.

Looks like the switch is on the side of the motor, connected to that push pull rod.
tinkered around with it a little bit today and discovered that the actual switch that the pull rod attaches to is bad. Are there any makers of this replacement part that anyone knows of? Searched endlessly for electric motor pull rod switches...etc and every combo relatively close but can't find anything. Switch has a short...wiggle it a bit and it will start the motor. Motor seems to run great!

My DP220 had a date cast-into, not stamped, in the underside of the table. It was dated during the WW II Battle of the Bulge, late 1944.

This site listed serial numbers and description for Delta saws...wondering if the same dates would apply for the Drill press? IF so, mine indicates a 1951 model...
Any plate with a Milwaukee address indicates a machine made prior to, and including, 1952. Any machine wearing a plate with a Pittsburgh address indicates a machine built after 1953.

My Delta wood lathe has the same type of switch on the motor, I would guess they used it on several other types of their machines as well. I think that the switch itself is probably about the same as a regular old household light switch, you could maybe get one of those and drill a hole in the toggle to accept the push-pull rod.
Or, just take the original switch apart - typically what happens is the contacts get dirty so they don't make a good electrical connection, rubbing them clean with a pencil eraser works well.

I've been searching...and it looks like you may be right. I have found a couple of toggle switches with a flat post that could be drilled through. I will go out and try cleaning the contacts and see if that works first. Thanks!
No. Switches that control motors are not the same as light switches.
To switch a motor you need to ensure the switch has a HP rating. Motors typically have an inrush of current when starting. The switch has to have contacts that can handle this large surge of current.
