Grimes Electric Oar

[Matthew Pieklik]

I’m Not one for electric outboards but I couldn’t pass on this one. I believe it is a 1932 Grimes Electric Oar Made in Syracuse , NY.          621 Erie  Blvd East. My home town, so I had to have it. From what I can see, It looks like it has forward and reverse and 2 speeds. The motor must weight  about 40 pounds. The motor has 6 terminals. 5 and 6 are for the armature. 1 and 2  are for a electro magnet and 3 and 4 are another coil.   When hooked up to 6 volts, armature and coil 1 and 2, it goes fast.  When 6 volts is connected to 1 and 4 with a jumper between 2 and 3 it runs slow.  Pretty cool with all the knife switches and cloth wire. Anyhow , My question : On the armature shaft is a brass connection/coupler that was secured with 2 set screws. They are out. I can spin the brass coupling on the shaft  about 180 degrees but cant get it off. I can probably spin it more , it’s tight but don’t want to push it.Any suggestions how to get it off?

Fantastic artifact you dug up. It looks like it was
made in Frankenstein’s laboratory!

Prepare to be boarded!

That’s an amazing piece!I think rather than spin that piece off I’d be inclined to pull it straight off using a small gear puller.

The shaft is probably galled up or has ridges where the set screws bit into the motor shaft. if you can’t access those spots and deburr them with a file, then the best approach would be the puller as Stanley suggested. it would do the least amount of damage to the ID of the  hub. Spinning it to work it off might actually remove material from the ID of the hub and make it sloppy when reinstalled. Hope this helps, that’s a really nice piece of history you’ve got there.

He's livin' in his own private Idaho..... I hope to go out quietly in my sleep, like my grand-dad did..... and not screaming, like the passengers in his car...
