Good day to you all. I just joined the group after getting a bug for hand tools. I just purchased an old Stanley 03-043 Push drill. Turns out it arrived in almost pristine shape. The sliding metal shaft had absolutely no scratches marks or rusting—that is until I had unscrewed and lowered the bit storage handle. Immediately a single vertical scratch appeared where the bit storage handle slides down over the main shaft. I thought it was possibly my imagination, having missed seeing an existing scratch. But the next time I opened the handle, it produced yet another vertical scratch.

I could either stop crying and expect that since I will be using the drill, there will be scratches etc. on it. But if possible, I’d like to take it apart and try and remove any burrs that might be on the mating surface. I did find one description online on how to disassemble a Yankee push drill (at http://trestore.wkfinetools.com/boringTools/ypDrill-thompson/ypDrill-1.asp), and I have removed the top pin in order to take the shaft out of the drill. But I’m stumped on the description on how to separate the bit compartment/handle so that I can get to the inner surface and polish off any burrs. Any helpful pointers here would be greatly appreciated. And I am attaching some photos of the drill to aid in this discussion. You can actually see two scratches in the second photo.

Thanks and advance for any pointers here.

I can’t get your link to work, but I found this one: http://contrib1.wkfinetools.com/jThompson/ypDrill/ypDrill-1.asp
Doesn’t seem to mention anything about how to separate the bit compartment/handle, can you copy paste that short bit? I have several of these, and if I get a chance I’ll try to see if I can get one apart. Not really my strong suit, but I have one in bad enough shape I’m not really worried about damaging it trying.

Also, once you get the burr off, you shouldn’t have much trouble polishing those scratches out if you wanted to.

Hi Tim, you did run across the same writeup I had found. I’ll grab my drill tomorrow and try again. Looking at the third picture, there is a threaded ring on the opposite end from the handle, at the end of the shaft that the handle rides along. Perhaps that can be removed to allow the drill bit housing to slide all the way down and off?

Tim,

I should have mentioned that the first part of knocking out the pin in the top part of the handle went exactly as described in the description we found. And with the handle pin knocked out, this allows the bottom portion of the drill to be removed. I didn’t even consider removing the remaining threaded ring off of the drill shaft and sliding the bit handle down off the bottom end. Thanks in advance if you end up solving this before I do.

Some of mine are the older models that are put together differently, but I found one that has that pin. I didn’t get to try pounding the pin out, but it does look like if you knock it out and unscrew that ring, the handle part will slide off. I’ll try today if you don’t get it.

Oh and welcome to Lumberjocks.

So yes that worked. With the pin out part of the shaft slides out then that knurled ring at the end away from the handle unscrews and then the handle comes off. The other end where the pin goes through I assume is a press fit, but maybe it’s threaded too. I didn’t try too hard to remove it either way.

This shows after the chuck part of the shaft is removed. That little knurled ring is what unscrews.

Tim, thanks for the help here. I followed your instructions and removed the ring and handle. This allowed me to get my finger in the end and feel the sharp burr inside; it was a sharp edge on an inner ring. Stanley (the company) labels these two items as a “magazine nut” and a “magazine nut ring”—referring to the bit-housing handle as a “magazine” I assume. The ring serves to hold the magazine from sliding down when the nut is screwed into place.

So the magazine nut ring had sharp edges on the end, which I filed a bit smoother with a small file. I am including some photos that show the magazine nut ring inside the magazine nut, another photo with the ring removed, and a third photo that shows the parts in relation to a groove about mid-way down the cylinder unit, which the nut ring compresses into when you thread the nut up to lock the magazine (handle) in the up position. I hope that it is smooth enough now to prevent any further scratching, however if it still gives me problems i’ll do some more filing on the nut ring ends. Nice to expect my (almost) pristine Push Drill to remain in such good condition now!

Thanks again, Tim!

Glad you got it fixed up. You’ll find a lot of tool nuts here.

Have your say...
