Craftsman Bench Grinder Age?

[bstoehr52]

Hi everyone! Pardon me if my post doesn't fit here as it is my first post on this forum.

I acquired an old Craftsman bench grinder recently and was looking to see if someone can help me determine the manufacture date?

Model: 410.19660
Design: A561X2000
3/4 HP

Can't seem to find any information online!

Thank you for any insight!!

The true manufacturer should be listed at the top of that page.

ALSO... does anyone know how to get the inner flanges off so that I can take off the gyards surrounding the wheel-wells? They seem like they are stuck on.

Do they turn on the shaft at all?

They do not :/

They do not :/

Ok... I've had success doing this on zamac cast flanges

• Install two nuts on the right arbor shaft and tighten them against each other (jam nuts).
• Heat the left flange with a heat gun. Apply a penetrant to the flange/arbor.
• Use a wrench on one of the right nuts, hold the left flange and twist against each other. It should begin to turn. Eventually it should turn rather easily with the heat and penetrant, but still may be stuck on the arbor.
• Using extreme caution, grasp the left flange, turn on the motor and gently pull the left flange. It may spin out of your grasp a few times. The heat generated by the arbor spinning in the flange should allow you to pull it off.
• Repeat for the right side.

Do you know of any other method that doesn't require heat? Are they meant to be disassembled or am I destroying them by removing them?

I don't have any experience with that particular model, but I've been able to remove flanges from every grinder I've had.

Are your flanges zamac or steel? Try a magnet.

More pictures may help.

To bstoeher52: The grinder you are talking about was made by Baldor Electric Co. from 1966 to 1968. In '68 Delco (which is the manufacture for Sears) came out with a 3/4 H.P. motor for there 8" grinders. the first 3 numbers in the model number are 397.

Delco with a a subsidy of G.M (General Motors Corp) and made electric motors and electrical products for 1939? all the way till 1984. GM wanted to get out of the electrical "business" and focus on Delco being a major electronics division for G.M.

What also interesting is that Sears didn't sell a lot of 8" grinders at all. There most popular sizes were the 6 and 7" size (1/3 H.P and 1/2 H.P.) models. As for the mfg date on you grinder there should be a serial number for it and the first number is the year of mfg and the next 3 number are the day of that year it was made. If you need parts for your grinder contact Baldor. Take Care.

Wow, you don't see many of those around. The flanges have to come off to get inside, so yes they are removable.

Also! Your grinder was made in January of 1967 by Baldor Electric Co. B-6701 the 4 is a Plant number and was made in Ft. Smith Arkansas. Also! As I said in my previous post Sears did NOT sell too many of them. They sold the 6" and 7" models as there most popular ones.
