Vintage Drill press

[Macaroni Kid]

Hey fellas, new guy here, names Mike.
Picked up a couple vintage Sears Craftsman utools, a grinder and a drill press. The grinder works fine I'm guessing from the late 60s to 70s era?. The drill press worked when I look at it, then I put the belt on and it wouldn't spin,then turned it on without the belt and apply light pressure to the pulley and the motor stopped? Apparently it will not work under a load. Now does nothing. Everything spins freely, reset button popped and will not reset?
Brought it into a local electric repair guy and he says it needs bearings (I don't think so)to start with which are $80 a pop? Then more to get it running. I plan on just starting with basics, power cord, switch etc. Looking forward to getting them operational and cleaning them up. Not looking to restore them, I like original paint but in excellent working condition is how I work my hobbies.
Thanks for the admission to the group, I like this forum as it uses the same server as my Truck forum does, hey I'm human and don't like change, a simple kinda man! Cheers

Grinder has the heavy duty base, kinda rare. Kinda.

Not sure when they switched to the flat tops...?

Nice haul. That 3/4 hp block will serve you well.

Looking through images and info on the grinder and can not find any other images with the "Sears best" insignia, was hoping to date this beast?, Would the serial number give this info?

EDIT:
I believe the 3/4 hp, square-top, split phase grinders first appeared in the 1976-77 catalog. and were referred to as "Sears Best".

The 1 hp in the 1977-78 catalog is referred to as "Sears Best".

You might conclude that yours is a 1977 model. Also check for a date stamp on the bottom plate.

Cool, good info Frank. Thanks
I will definitely be going through your Drill press thread for sure.

I would carefully check the wires in the motor for rot/cracking if it's been sitting a long time and uses a centrifugal switch, the switch could just be stuck from old dust and grease and ****.

Drill presses don't usually load the motors enough to burn them out. Before disassembling it, blow out thoroughly with an air gun, check the plug and wiring.

For the motor:
1. Measure the ohms of both the start and run windings
2. Is there any lateral play in the bearings even though it spins fine
3. Test the start capacitor
4. Remove the end cap and inspect all wiring, inspect and test the centrifical switch.
5. Is the rotor centered in the stator
6. Is the motor wired for the correct voltage

That base doesn't look right but I could be wrong. Has it been previously repaired or modified.

Looks like a couple of nice finds! I assume the gold paint is original? I have a couple of old machines that need to be cleaned up and repainted, so I'm looking for suitably vintage colors.

Remove the grinder from the base and flip it over. The date might be on the bottom.

Base appears to be correct and original. Paint is same OE paint as upper press, and I purchased from original owners daughter.

Also if anyone has an extra handle...

On the DP motor it could be a bad capacitor or it could be mis-wired for 220 on a 120 plug.
Those are two common things with older tools.
I don't believe bearings should be $80 each. They should be a pretty standard size and more likely closer to $8.00 each.
Take a look over at OWWM.org and vintagemachinery.org. You'll find a lot of info there as well.

 

[Macaroni Kid]

Thanks Rodney. Yeah, I could tell the guy was being lazy and didn't want to work on the motor, hence the $80 bearing price. LOL
I'll check out the other sites you suggested
Thanks, Mike

I think i do.

Ok great, let me know

Hey fellas, sorry for the lack of updates, multiple family illnesses have struck my family starting with multiple ambulance/hospital visits for my elderly mother and two others also hit with cancer,
2019 not going so well.
I finally got around to playing with the drill motor. After some disassemble, inspecting, then reassembling and getting nothing, I decided to step back until recently. I plugged it in and did nothing as expected, through total frustration I rapidly pressed the reset button and it whirled to life!. Grabbed my air gun and blew out the years of dust. Mounted it back to the unit, put on belt, but had to help it rotate the assembly so a quick careful pull on the belt aided it along. I excitedly grabbed some penetrating oil to help loosen up years of old hardened grease. Very happy to have this unit operating. Still working on some bugs, like shaft pully riding up with upward movement, have to look into some of the online exploded views here.
Just want to say thank you to all the help given by this great forum, looking forward to contributing back and visiting more
Mike
