Bob, I don't think it would have been 5/8. The hole in the pump rod is 5/8. The square part of the rod is only 7/8. After looking at and trying a 7/8 pin , it might not be too big. I'm going to guess that it's no smaller than 3/4. Is there a small brass insert inside the hole where the Babbitt goes ...

Thanks Bob! The 7/8 seems big but I will have another look. Won't leave much room for Babbitt around it.
One other question. Did the pump rod guide have Babbitt in it?

It's an 8 foot mill. I wondered if the pin on the pump rod was riveted over. Will look at your site. I was thinking they might be something like 3/4 diameter.

Anyone have the dimensions of the pins that go into the pump rod and crank plate on the direct stroke steel star? I know the one for the crank plate is a bolt with left hand threads. The pin that goes in the pump rod looks to have a step down in it. Need to make both these parts to finish this mill ...

Sorry to hear this. Prayers for Ken and the family.

Pretty neat find. It's a Savonius rotor.

Very cool machines! I know where a Jake is. Not sure of the model/size. The guy has the control panel for it too.

Great old pumps!

The Amish that are about an hour south of me still use windmills as well as pneumatic pumps.

Love the picture.
