Delco bench grinder

[DDOPWD23]

Here we have a 1967 Delco 1/3 HP bench grinder. I know it looks like a Craftsman “tombstone” grinder. Of course Sunlight or Packard Electrical made the 50s era grinders and then it went to Delco Electric to make Craftsman bench grinders for Sears. I got this for free because it wasn’t working and I tried my hardest to get this thing to work since I never saw one before with a Delco data plate. Has anyone else seen or owned one of these?

Nice paint job. I've never seen a Delco badged grinder of that era.
Did you get it working?

I think there was a picture of one floating around years ago. Definitely never seen one in person.

Yes and no. I tried the PO burnt up the starting windings on the stator. I found a half dozen broken wires and solder them and them put all new insulation varnish on it but there must have been more broken wires in the stator. I could get it to start up and spin but it would get really hot and start to smoke. The bearings that were on it were shot so naturally that was the first thing I replaced.

I bought a 1967 craftsman grinder that was being sold for parts so I just intended to replace the stator but I was surprised they used different parts on the inside. The Delco is a 1966. I know in 1964 Delco switched from cast iron to cast aluminum. I know this one was cast iron but they had too many differences. So I tired finding a 61-63 grinder but wasn’t going to pay over $150 just for parts. I wound up finding a 1955 craftsman and just changed the stator band. Which is why you see a whole in the back of the band. That’s were the power cord comes out on a Delco. A Sunlight/Packard it comes out the side. When I come across a 61-63 I will make it a 100% Delco parts. I will also have Matt Blast make me a new data plate as well. You can see the slight offset of the rotors. The craftsman stator sits closer to one side not in the middle.

Yes when I was trying to get some information on this grinder I came across that post and that’s pretty much all I found. My question is what store would have sold this. Was it in a Sears store for you to get since it was practically the same thing as a Craftsman?

A little late to the party here but I have a grinder very similar to this that came as part of a Belsaw model 1055 saw blade sharpener: http://vintagemachinery.org/pubs/detail.aspx?id=20462

The grinder on mine looks almost the same as yours for the center section and tag, but doesn't have the wheel guards or grinding rests since Belsaw equipped it with other attachments. My tag lists part number C-2373, Ser. E-64, Frame 48, 3.5 A (but same 1/3 HP and RPM).

Thought I'd share this in case it helps anyone find parts or discover where they were sold.

I see an overheated start winding. It has shorted turns and will smoke up because it is effectively a transformers shorted secondary winding.

Seeing it is the last 2 coils added to the stator I would have removed it and reassembled the motor and test run it after giving it a hand spin start.

If no smoke then the run winding would prove to be sound.

Then the challenge is to make two new start coils or find a rewind shop to do so.

It could be that simple but you have learned a lot along the way.

YMMV

New to tool restoration and have one these I got from my grandpa. It works flawlessly and isn’t in bad shape but could use fresh paint. I’m curious what paint you used, I want to be as close to original red as I can.

Welcome to the group, it’s addictive so be careful. I used rustoleum regal red and flat aluminum from VHT. I then just put on satin clear to knock down the gloss from the red.

I picked up this Delco at least 10 years ago, no back story that I can recall. It's dated Aug 29, 1966, and runs silky smooth.

That’s the same one as mine! I didn’t think there were any others out there. And that is the same year as mine 1966.
