Vintage Windmill and Wind Generator Forum

I looked at the old mainshaft from mine. No hub threads, just the nut threads on the end. The entire length of the shaft (for the hub) is tapered for the hub. And then the key. I would imagine a very tight fit. I would also imagine heating the hub before the big pull. Thanks windy, I've put this ...

Well we will try this weekend with some heat and the puller plate. Hopefully fingers crossed it pops off then the repairs can begin, again.

Thanks Mike ill let you know, I have another plan I thought of just going to take some time to build a custom puller.

Well, things did not go well this week. The key is completely drilled out but the hub will not budge not sure why it's not a press fit but something has gone wrong and we'll the hub flange snapped. I've been here before and it was taken to a machine shop to press the hub off, I just don't know what ...

Well we have taken a few steps back. Putting it together last night noticed another crack had developed right above the keyway in the hub. Not the end of the world but frustrating, went to drill out the new key to remove the hub for welding and the drill bit snapped halfway through. So no we have a ...

I used to do it the old fashioned way, now if I have a digger derrick handy sometimes I hand the tower secured until the concrete dries on the anchors. Now I often hinge them and on some I build a square base to hinge out of oil field pipe, I don't like the looks of a pipe frame on the ground but ...

So we have always done it one way when we raise windmills. We fully assemble them on the ground then lift them set them in the holes and use a plumb bob to make sure they are standing straight and fill the holes with concrete. Its worked fine but were getting to some locations on our ranch we can ...

Been working on getting this thing back together. Hit some snags and it's back apart, but hopefully have some fixes. But when it was together it ran smooth as silk. Its always leaked but I never knew why, axtel used machined surfaces for sealing but over the past 90 years there is a few thousands ...

Thanks for the compliment, epoxy floors hide alot haha November 9th it and 3 others go up.

Thanks windy, it's the same size chain that came on the mill when it was working and length I think the just looks big. I'll have to get the tailspring and tail and get it all set up. That appears to be an awfully large chain. Here's the deal......In between the horizontal pulley and the hook, the ...
