Need Help Drill Press Part Needed 1951 Sears 103.23141 15”

[[email protected]]

Hi

I have a 1951 Sears 103.23141 15” Drill Press. It suffered some damage and I bent the Spindle Assembly (part number 27130) marked 28 on the drawing.

I am looking for ideas on how to fix this problem. I think somebody may have a piece that would fit. It is a King Seeley make and maybe all the 15” drills made by this company are the same??? Or maybe somebody knows of a moder spline shaft that fits??

I have been thinking about straightening this shaft, but it is a bad bend. It may not be possible. Also, I don’t know what this drill press is worth, but I need a shaft that makes some economic sense.

What cha think??

I'd put it back together and try straightening it. What have you got to lose? I've straightened a number of drill press spindles. Get a piece of steel, as large as the chuck will hold, probably 1/2", and hit it with a hammer to straighten it. Best is to have a dial indicator to check your progress, though you can probably get pretty close without one.

I'd try to straighten it holding it in a vise (with soft jaws). Pull it back in line with a pipe over the end. If the chuck is held on by a taper, it probably will not stay on with side blows.

Done a bunch, never had a chuck come off.

I'd watch ebay myself. From the looks of where it's bent, I wouldn't even attempt to straighten it, what with it so close to the bearing.

Why, what does he have to lose? Worst case, he still needs a spindle.

I have nothing to lose by trying to straighten it. It is just the bend is so bad, I think it is seriously weakened. I also thought about cutting it off and welding a larger diameter there, then using a lathe to trim it down to the correct diameter and true it up (A lot of work). I thought that a machine shop might be more able. I also thought this part may be generic enough to be found in some other application (it is a rod with a spline). But the easiest way would really be to get a replacement part. Somebody have a parts machine or a replacement part?? Where is the old drill press junk yard? Or am I the guy running the junk yard with every part except the spline?

Frank,

Sorry for your problem. I received your pm, but thought I'd answer here.

I have four bent spindles at the moment in various degrees. I tried straightening one, but gave up because I just don't believe I have the proper equipment to do so. I've heard of straightening spindles with a large press, but never tried that. I could send one or two of the lesser bent spindles for shipping cost.

I think ebay is the drill press junk yard you're seeking.

You may need to think outside the box for a fix. I once used a spindle from this smaller Duro drill press into a Craftsman dp. So other brands may work just fine.

Another option is to use a quill/spindle assembly from the next gen Emerson/Craftsman dp like below. It's longer but will work with a minor modification to the feed stop bracket. The quill would extend about an inch below the head frame.

Nah, not seriously weakened, the spindles are actually pretty soft, as steel goes. It actually takes very little to bend one, which is why it doesn't take a whole lot to straighten one. I suspect a lot get bent when drilling in an unclamped work piece, the bit grabs, the part "helicopters", and being out of balance bends the spindle. That's my theory anyway.

Have straightened them on a lathe.

Works well!

Thanks, It makes sense that the next generation would fit.
