Delta DP 220 vintage wont lower down

[gumboguy]

Hi Guys:

Thanks for having me in the group.

My dad has an old time Delta DP 220 drill press, probably from the 1940's. Motor works and stuff, but we cant figure out why the drill head wont lower down. Its stuck. Is there some sort of safety lever we cant find? Is there some cotter pin or something that has sheared off inside?

Any help would be greatly appreciated.

Please advise.

Welcome. Some had a quill lock, usually just above the chuck on the left side. Can you post a pic?

This isn't a 220, but it is a version of a Delta. I have an arrow pointing to the quill lock lever that 454 referred to. If that is loose, then try some light taps on the spindle. Use a soft faced hammer or a block of wood so you don't damage anything. If that doesn't work, then try some penetrating oil down the spindle.

Pics Please!

Do you mean you can not lower the quil with the lever to drill a hole.

Or you are trying to lower the head down on the column.

I mean I cannot lower the quill with the lever to drill a hole. thank you.

pictures attached.

The handle seems to be stuck with a tiny bit of play. It feels locked up. Like not just having a big hard drag, but wont turn at all. Is it true I can bang on the handle with a hammer?

Please advise.

 

[gumboguy]

yes, thats very loose.

That lever directly below your switch is the quill lock. See if it is tight, if it is loosen it up and try again.

 

[gumboguy]

pardon me, im a noobie to the machine tool world. What is the spindle? What is the quill for that matter.

please advise.

It's the little handle on the very front left. I locks the spindle from moving up and down by compressing the split in the front of the casing. loosen it up and see if it moves freely. Do Not use force to get the main handle to move, you will break something.

If the spindle lock is loose and the spindle is still not moving, other options could be that the teeth on the gear are buggered or the spindle is fused to the bearings.

Thats the kinda thing I was afraid of. :-(

Pull up and down on the chuck and see if it moves even a little bit. Move the handle back and forth and see if the pinion shaft moves a little. Pinion shaft is the part the handle runs through. Also right below the spindle lock is an adjustment screw. Loosen that a little. That thing looks too nice to be rusted together.

Ok Guys:


Anything that looks like it tightens the body against the quill shaft is plenty loos. I even tried to pry the body open a smidge with a big screwdriver and that didnt help.

When you grab the handle to pull the drill down, it moves down about a 1/16 -1/8" and then binds up.

I guess the gearing in the spindle or handle assembly is "buggered". :-(

if anybody has any other ideas or can affirm the idea that the gears are buggered, id sure like to know.

This machine tool is in excellent condition for its age. Its a damn shame that it doesnt work.

Please advise.

i did find this though:

It's already down a bit. Try gently pushing it up. Put a carriage bolt or something in the chuck and tighten. Then position the table so you can place a 2 x 4 on a block to make a lever. Do this from the back at an angle, it's stronger coming in that way. While pushing the chucl, quill and spindle up with the wood, try to move the hand lever up and down to free the quill.

Don't force anything, Do this gently and work that mother. It will break free eventually unless something is broken inside. In that case, remove the return spring ***'y carefully (don't let it bite you) and withdraw the handle and feed shaft.

Here's a thread about doing this and here's the pic of what to expect:

There's probably gunk-****-poop inside the head gumming up the rack and pinion gear (quill and handle assembly)
It could be sawdust, hardened grease, metal swarf or even mouse's nests.

Pull the pinion rod out and inspect/clean

 

[jakemac]

I'm thinking that the 1/16-1/8 slop in the handle could be loose tolerance in the gears of the rack&pinion. If so, then its the spindle that is seized.

Remove the pulley and dose the bearings with penetrating oil. Then periodically give the spindle a SOFT love tap with a rubber mallet (against a block of wood) on each end. Repeat until it breaks free.

 

[Bobioz1]

Don't pry or beat on anything, just take the pinion out. Then you'll know where the problem is. The return spring is wound tight, you have to hold on to it tightly and walk it back one turn at a time. The pinion should be out in minutes.

 

[CalsXS2]

Silly question. But you don't happen to have the quill stop nuts turned all the way down do you??

In you first pictures they are at the top of the threaded rod.

Where are those nuts. Show us a pic,,,,lol.

 

[CalsXS2]

See the lower small screw. Is it loose, and the lever above it.

It doesn't look like it's in bad condition. I would soak everything that looks like a moving part (except belts and pulleys) in Kroil or PB Blaster for a couple days and then try to move it
