Vintage Windmill and Wind Generator Forum

Dan Benjamin and I had talked, and txted pictures of gears and suck back and forth. He doesn't have the parts I need.

Much like this mill's shaft the day I got it, I'm kinda stuck...

Meanwhile I've made progress on my Ural motorcycle and 4x4 7.3 Diesel campervan, so there's that

Perfect, thank you

I was basing the size comparison (8.5’ v 10.5’) on the hub sizes and bolt holes on the hubs as your hub has more bolt holes to affix to the spokes. Yours is indicative of a larger mill.

more pics so you all can see what I'm working with, and for ID purposes

Yes, that looks like the drive cover and shaft I'm working with.
