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.


I see what you mean, your 5 spoke hube w/single holes vs my 6 spokes hub w/2 holes to attachment. Mine has to ...

backside of the hub and lined brake shoes. It's a Timken bearing model.

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

My job keeps getting in the way of my hobbies... I'll get some pictures up later this evening.
