DP#98, Band Saw
DP#98 is a Craftsman 100, model 103.23130. Because there are machine screws attaching the trim panel to the head casting, this is a 1950 or earlier machine. The date code on the Dunlap 1/3 hp split phase 115.7269 motor, M1 49, supports that.
I got the drill press in a bundle deal with this Craftsman 103.24280 band saw. This motor is also a Dunlap 1/3 hp split phase 115.7269 dated F2 51. Both machines were well cared for for quite a while until they weren't. They both should clean up very nicely though.

The band saw and motor are cleaned up and already have a new home.

Today, I started tearing down and cleaning the '49 drill press motor, model 115.7269. It's very dirty as is typical. These old switches with the bakelite toggle are often bad, as was the switch on the band saw motor. Fortunately, this one still works fine.

After:
I used an old spark plug boot as a cord strain relief.

This morning, I dismantled the head frame from DP#98.
There were a few surprises.
- Both spindle pulley retaining screws were broken. That's not unusual, but the broken end on one is bent over and the screwdriver slot is fubar. I'll need to drill that out.
- The thrust collar nut does not appear to be original. Normally, these are cross-hatched knurls. This one has vertical knurls. That's no big deal, but the internal threads are less than half of the nut. When fully threaded onto the thrust collar, it spins. I initially thought the threads were stripped. I will likely replace this 6A chuck with a 633C chuck with safety collar. We'll see.
- The set screw on the spindle collar was very loose. NBD, but I don’t think I’ve ever seen that before.
- The inner snap ring on the spindle pulley assembly was jammed between the lower bearing and the slot. It was rather difficult to remove. I think the bearing spacer is a tad too long. I've never seen that before, but it's an easy fix.
Overall, everything appears to be in great shape. Runout is ~0.001. The chrome looks very good. The head frame trim is very nice. I believe the original paint will clean up beautifully. This is going to be a very nice machine.

Progress.
New bearings arrived late today, so assembly should speed up.

Today's progress.
The chuck was also dismantled, spent a couple cycles in the sonic cleaner and is now soaking in citric acid.
It cleaned up beautifully and operates as smoothly as new.
