Those wrenches are cool. I’ve seen them attached to the down tube under the seat. Also MMeyers, the crank nut does have “standard threads not reverse! “

If your nut is on the side opposite the chainring.

Oh goodness you are right about that! I didn’t think about which side. I checked my 1912 because I knew it was only hand tight, and that nut is on the chain ring side. Sorry for the confusion. Thanks Iverider.

After close to 100 years without being touch by a human. This gal was not going to make it easy for me.

A couple of drops of lube oil and patience.
Using an old bike wrench which fitted into the two slots and slight force I managed to
loosen the nut so that I was then able to remove it by hand.

Thanks for that and for the diagram!!!

I used 2Jakes method, before I got the actual tool. I clamped vise grips as close to the nut as possible (on the flat bike wrench tool) to give some extra leverage when needed for removal.

I didn’t used vice-grips...but if you do...
Vice grips on the wrench tool only!
Now you have more leverage.
But apply it in short amounts of pressure.
You don't want to disfigure the slots on the nut.
It may take time...use lube oil.
Eventually it will loosen.
Good Luck

The Vise Grips give you far better grip on the wrench tool to better keep it from deforming the nut.
