Vintage Drill Press Identification

[Defender92]

Hey guys. I picked up this drill press on Facebook yesterday for $10. Saved it from the scrap yard. From the best I can tell by google image search it’s a Dunlap or Companion. Can anyone confirm this?

I have a spare motor that I’m going to place on it. 1725 rpm. Any leads on a new quill spring cover? That’s about all that’s keeping me from running it.

Also, does anyone know anything about replacement chucks? As in what type? Is this a weird threaded on type of chuck???

The plan is to get it working well and repainted. And I’m seriously considering adding a third pulley for slow speeds.

Thanks guys!

It looks like a sears roebuck model (http://vintagemachinery.org/photoindex/detail.aspx?id=13113), but that sure looks like a jacobs chuck on there.
It looks like one of the plain bearing models, but it also loks like it has the locking right for a threaded chuck like you woudl have on a jacobs multi-craft chuck.

There should be some numbers on the chuck body:

that might help tell you what it is.

There's probably lots of re-brands of that particular press. Common practice way back when for everything from manufacturers to department stores. Here's a Dunlap ad from the same period:

Looks pretty close to my eye....

Yep, it's a sears model. check here: http://vintagemachinery.org/pubs/269/4728.pdf or http://vintagemachinery.org/pubs/269/1813.pdf and look at the parts list. Same part number on your base casting as in the parts list.

Don't quote me on it, but I think it was made by Atlas for sears (Dunlap).

Nice, you got a $15 drill press for $10

Thank you! Yes I believe you are correct. The BDIA-3 casting mark on the base matches the parts list. I was looking and looking for this document with no luck. Thanks!

Here’s some more photos. It’s a Jacobs Chuck No 33. 5/64-1/2.


I basically just want to remove the chuck and quill. I want to dissemble the whole DP and refinish it for service. Not restore but just get it running good for my shop.

I can’t figure out how to get the chuck off. Here’s a closer photo with some different pieces.

1 some sort of non spinning spacer that’s set screwed
2 freely spinning spacer?
3 a piece that appears to be pinned to the spindle
4 a threaded piece that I can screw up and down between the chuck and #4



I’m not sure which spindle I have on this parts list. It appears 2 different ones were optional. But the chuck is 5/64-1/2.
Any ideas on how to dissemble this??

Right after my last reply I figured out how to remove the quill and spindle. I’m REALLY thinking I have the BDIA-4B spindle. And it appears the chuck is not threaded and the chuck is the female end? I have it soaking in PB Blaster now and I will try to remove the chuck soon.



Does anyone know how to operate the “chuck release collar” 41-17 and “chuck release nut” 60-39 to get this chuck off.

Hopefully this is a more common chuck rather than a threaded chuck I originally thought I had?




The quill has brass sleeves. I’m ok with that. Everything seems very solid and well made. I love these vintage machines

A jocobs 33 should be a jt33 taper mount:

The “rings” look like the locks/retainers you would often see on jacobs multicraft chucks. Someone else will have to chime in on that one as I’ve never dealt with that type of retainer before. I will assume that as long as it is loose and spinning, it shouldn’t prevent the chuck from being removed. But verify that before trying to remove the chuck with wedges or a punch.

That 33 chuck is actually a quality piece. If its in decent shape, I’d run it. Or, if the jaws are worn, you can buy a rebuild kit for it. As long as the body isn’t damaged/worn, a jaw and split nut kit will make it as good as new. Much better than most replacements you can buy today. I’d go so far to say its even better than the modern Jacobs chucks…
