Old Black & Decker bench grinder

[imc188222]

Hello everyone. I've been a lurker on here for some time, never really posted though. There is so much good info on here I can usually find what I need. After considerable searching I have come up dry this time. In addition to hopefully getting my questions answered, I will use this as a project thread.

This old Black & Decker bench grinder is my current project. I bought it at a yard sale some years ago and since then it has sat, waiting for me to get around to it. I just love the way this grinder looks.

I want to narrow down, as much as I can, when this grinder was made. I'm sure someone out there must have an old catalog with this in it.

Does anyone happen to have the correct bearing numbers for this grinder in their notes? I tore it down today and I'm not convinced that it has the correct bearings in it. It has oil cups but the bearings are sealed. The bearings that were in it are 'Nice 1622DC'.
Thanks for your help.

If they are ball bearings, it would be fairly easy to measure their dimensions. If they are millimeter dimensions, they will be easy to source new bearings

Going by the logo, it is sometime between 1926 and 1960. Google Black and Decker logo.

As much as I admire those old tools, I would be concerned about the insulation on the windings and interconnects. Unlike modern high-temp insulations, those old coatings and rubber-based insulations break down over time and temperature cycles. I think it's great to find an old machine like that, but wouldn't consider it as a primary tool that I relied upon.

For example, I had a 50's Craftsman rotary tool (like a Dremel) that I used for many years. One day it just went up in smoke. I opened it up and the old windings were literally crumbling into dust. No fixing that, just tossed it. It was well made and looked sleek, but they don't last forever...

I have one very much like that as well. Picked it up last year and now have it shelved for a while so I can restore it. I did not look to deeply, but I did find an ad after a google search from I think 1926 that looks to be correct. They were quite expensive new.
Very cool unit.
