Vintage Windmill and Wind Generator Forum

In looking close, it is not symmetrical and it is two piece so that it can be bolted on anywhere. A snub block for a rope is not far fetched. If there is no evidence of a pull out (brake) handle having been in the tower anywhere else, that is a possibility too. Lastly, could be a directional arrow t...

My welder has a small lathe and he turned them. I just copied the idea from Dakota. There is some benefit to going up there in the friggin coldest time of the year!

I hope I didnt malign hinging too badly. It certainly can be done but if something fails it is not forgiving. Pump hoists are the nicest for down the well work. Cranes are nicest for stabbing heads on towers. A pump hoist boom does not rotate so they only way to go sideways is to lean the rig. The o...

Michael, I tell my help that I will say one thing wrong each day and it is your job to figure out what it is. If you build up enough tail pin holes, you can buy on ebay 5# Ni99 for around $75, makes them $1/rod. We use Ni99 on tail pin holes as it machines easier with a die grinder burr. Where you c...

Welcome, Jerry The groove mimics the style of case casting on the left. Once the dam around the oil collector fills, oil would have a natural tendency to flow toward the snout ring. If you dont build up the snout ring on this style of case casting, they will leak the worst as you have a down sloping...

In 20 years, I have used all methods from gin to hinge to loader tractor stinger to pump truck to crane. My preference is pump truck or crane. Hinging has limitations. I bought a D602 on a 40' trussed tripod tower last week that a guy tried to hinge down and dropped. There is a lot of pressure when ...

You still have a visible lip in the inside of the hub so it is likely OK. The inside of the hub wears evenly because the hub turns. The snout bearing wears on the lower side so the snout ring on the case wears only on the top. Wear on the snout ring is normally where you have to build up. The collar...

The new forum has the same glitch as the old one. I was doing a reply when Smax posted and it bumped my post. I hadn't exited so 2 hits on the back button and I could then post what I had typed without losing it.

Smax specifically asked on sail blade design which would be hard to determine individually. Many factors go in to a windmill's total efficiency. For example, the Dempster 15 blade 12A produced equal amounts of water as the 18 blade Aermotor. This study was done by a university but cant remember whic...

Ivan reported that during WWII it was hard to get metal for windmills so if the got material and built the mill they painted them yellow

Wrong color, it was orange. About like Allis Chalmer orange. Have seen a couple
