Newest find. Heavy duty 100, motor dated 4/47. Very dirty, but seems to be in nice shape under all that. Only thing missing is one of the feed handles broke off inside, but should be easy to make a new one. This thing is Stout! Probably going to swap this in for my late model 150.
Anyone have a motor dated earlier than 4/47? I know the 48 catalog was the first produced post-war. Thinking this thing had to be near the start of ramping back up production.
While looking this over, I think this thing has a 70yo rubber V belt still on it! Table is pristine, no holes whatsoever.
Hi Frank,
Thanks for all the great articles. A few months back I found an old Craftsman DP model 103.23640. I flipped the switch, it purred to life and I bought it for $70.
Since then I have used it on several projects, and then one day I screwed up. I was drilling though some 1/2" bar stock, when the tip of the bit caught and held that last fraction of metal and it started to whip the bar stock around. Like a dummy, I grabbed the bar stock with one hand and reached around to switch off the DP with the other. The chuck stopped rotating while I held on with my right hand, but the spindle was still turning.
When I finally got the motor turned off, I removed the bit and offending bar stock. I wanted to make sure nothing bad had happened, so first test was to turn on the motor again to listen, and sure enough that previous beautiful purr was now mixed with a slight thumping sound.
I turned it off, decided to tear it down to look for damage, and that is when I started going to the internet boards for assistance. I found your posts and they will be a great help when I start to tear my baby down for a cleaning and damage inspection.
I have one question: From my previous description of accident and current sound, would you have an idea where I should focus my search for damage?
Thanks much,
NOS
Excellent find, Frank!
A buddy recently got about a 1/2 milk crate of 'rusty taper bits'.
He picked some out and went after them with a wire wheel. Turned out they were nearly new and nearly all were made by Cleveland Forge. He now has nearly every bit on one of those drilling/tapping charts.
So if you have the time and/or patience ...
Frank: Seems like you have a museum of awesome vintage Craftsman equipment
Frank you're a fine craftsman and teacher. You inspired me to pick this up
So, my capacitor is kaput. Hey, it's at least 70yrs old. The capacitor is the sardine can type and doubtful I will find one to fit in the motor base. Question: has anyone installed the oval shape? I want to keep as OEM as possible. Not sure how I should mount a replacement. Also attached some pics of my bases and column. Lots of hand sanding on the column- went with the orbital on the bases- thought you fellas may enjoy that tool
Frank- I haven't popped the motor open yet, it's next on the list. I included a pic of the stand. I had this channel shaped piece of wood that was very convenient to hold a bench model column in place. Pretty pleased with the nevr dull results on the chromed parts. However, the chrome started to lightly flake in some areas so I backed off. Regarding the capacitor- great idea about running thought the oval holes in the motor. Now, anyone have a capacitor recommendation?
Also, I want to point out that I have a 2 young sons. This project is teaching us that items and can be repaired if originally manufactured with quality in mind. It has been a good teaching experience. Not everything needs to be hauled to the curb when it stops working...
After a week of bugging them they finally got back to me. Some kid went to look at it for $100 (they raised the price from $20) and he told them it was junk. They gave it to me Just to get rid of it. I gave them $20 anyway which is what it was originally on CL for. I think a complete teardown, cleaning, and paint is in order and I'm well into that. The trouble is that I've been through this whole forum and the catalogs and I still haven't seen one set up like this. I know it was part of a multi tool setup but on those the stand is much larger and the DP lays down into a cradle. The number on my stand is 103.9770 and the motor is 115.19790 (3/4HP). There is no number on the DP but I'm guessing it's 103.21761? I think I'm going to twist it into a bench model by buying a base and moving the motor up on the head in place of the 90 degree pullys. 96" of twisted belt whipping around in my shed doesn't sound too safe. Sorry for the sideways pictures. Only so much I can do with a phone from work. Any suggestions?
That's a nice find for $20! I can't recall seeing a set-up like it here either. IIRC, I saw the tilting parts on eBay a while back. I believe you're correct on the model number. The motor has a date code of 5/58.
It looks like it had a rough life out in the elements. It can be revived, but will take a lot of work. I do like your idea of converting the DP into a dedicated bench model. What's your location? I have a base and motor mount that will fit.
The 1957 catalog has a similar combination machine. The base is larger, but doesn't look as heavy as yours. http://vintagemachinery.org/pubs/222/4403.pdf#page=11
I'm in California, MD. The unit was in a shed right by the water which probably accounts for the "patina" lol. I have a motor mount stamped 18921-103 with the extra rib on the way from ebay for $17 that should fit. The posts are the correct size and spacing anyway. Id be willing to trade the table for the base you have if you have a need for it or know someone who does.
A recent estate sale landed this 150 with vari-slow and a Dayton 1/2hp with forward and reverse switch. Paid 150.
Frank, thanks for the thread and all of your information. Looking forward to replacing the belts and cleaning this up.
Yes, that is the correct mount.
Do you have two tables? You'll still need a table with the base. How tall is the column? The diameter should be 2-1/4".
Did you test the motor yet?

Frank,
The column is 2' 11 3/4" with a diameter of 2.23" on both ends.
Typical columns for Craftsman 80 bench models are ~28-1/2"... at least that's what my spare 80 column is. Craftsman 100 bench columns are ~33". So, your ~36" column is a real bonus!
The motor runs fine but is full of sawdust and makes some strange ticking noise when rotating by hand. It sounds like a peeled paper edge rubbing the armature.
That ticking noise could be a dirty bearing, the centrifugal switch collar or other debris inside.
On a side note, I'm an *** and dropped one of the bearing cover screws inside and can't find it. I assume it's stuck to something magnetic but it needs to come out of course.
Been there, done that. I dropped one in when I was almost done reassembling and had to dismantle again and find it. Since then, I've accumulated a variety of screw starters and always use them on the bearing covers. The long screw starters work very nicely when reaching through the stator to remove screws on the inside of the terminal end cover.
Also, positioning the motor on it's base with the shaft horizontal minimizes the chances or a screw falling inside.
I don't think there are any magnets inside these motors. It's probably just stuck between the stator and cap or band.
I can't get the fan side endcap off so I'm going in with an endoscope tomorrow.
The fan side is the easier to remove. You may need a chisel or similar to remove. There are several motor rebuild threads on GJ. Here's one of mine that may help.
I assumed turning it into a bench DP with a base negated the table. I don't really have floor space for it in my 10 x 16 shed. I assumed it would take the space where my old benchtop DP is. Please elaborate on how the table would interface with the base.
This was my assumption of what your conversion would look like. Without a table, drill bit height adjustment will be more difficult moving the head frame up and down.
Please note that I have that rod on the table that the motor slides L&R on to power different attachments.
That rod and that motor mount would no longer be needed on a bench model drill press.
I'm also currently struggling with getting the bearings out of the quill. I'll be seeking more advice at work tomorrow afternoon. All I have left to do is to R&R the bearings on the quill and pulley, paint, and reassemble. Thanks in advance for all your help.
Sometimes there are burrs, dirt, dried grease or other obstacles on the spindle that make removing the bearings more difficult. I use a small file or sharpening stone to remove burrs from the spindle. Some type of bearing puller is often required. This post may help.
New to the forum so wanted to say hello. Received a drill press from my father-in-law that has is in great condition but has a few issues that I wanted to ask about to help me get parts for it and get it back in service.
1. From FrankLee's amazing spotter's guide I think I have a 1952 or 1953 Craftsman & Dunlap 12-1/4” model 80 (see attached pic). data plate says 103.23100, straight handle with no knobs, oval badge with no trim. Is this correct?
2. The spindle pulley has been taken out and has no bearings or spacers on it. It does have the washer and c-clip, as well as a brass spacer. (see pic#2) Does the brass spacer belong there? I don't see what its function is, nor do I see it on the parts list.
3. From what I can see the splined sleeve threads onto the spindle until the c-clip rests on top of the bronze bearing pressed into the head. That cant be right is it?
From what you can see how is this incorrect and what parts do I need to fix it? where is the best source for those parts I need?
Happy to join the forum and look forward to your responses.
Glenn
I see what the problem is. the shaft was assembled upside down. it should be c-clipped BELOW the brass bushing with the upper end protruding out the top for the pulley to be set screwed to.
You are a genus. I stared at this for hours before I got your note and it made perfect sense. Now I just have to disassemble it and put it together right. oh well, I wanted an excuse to take it apart to clean and paint it!!
First, thanks Frank for all the help.
It appears that the noise maker was the belt. After extracting a broken adjustment screw and replacing it, I was able to install the new belt. After fiddling with pulley height a bit, I turned on the motor and the sound was back to normal.
The previous thumping must have been a worn spot, as you mentioned. I still plan to tear down and clean at my earliest opportunity.
Thanks again for the help!
Me. Frank lee, first wanted to say that I have enjoyed this whole thread. Thanks for sharing all your work with the world. Next, I have two Craftsman DP that I will restore thanks to your thread. I am having a ball!!
First post for me good sir!!
Appreciate you ��

So I am correct that this is a model 80 12-1/4" right?
