It all came together today. Now for the bad news. I need to make new spokes.

I mentioned early on that the threads on the spokes were #14-20 instead of the 1/4-20 that I had intended. As I was doing the final tightening of the wheel, one of the spokes wouldn't tighten and slipped instead. The proverbial "stripped thread" but the threads are intact.

So what is the difference between #14-20 and 1/4-20? About .008", which is about 25% of the thread depth.

New spokes have been made.

Spokes consist of 1/4" HR threaded both ends, a nut and a sleeve. Nut and sleeve are silver soldered on one end.

Test spoke on the left, setting up the remaining spokes for soldering.

Complete.

Stood the windmill up this morning. Cranked easier than I thought it would.

The first casualty happened while it was still on the ground. I was adjusting the furling arm at the base and my BIL was holding the tail. Pulling on the lever with the tail held stationary meant that the motor had to lift and the rods were not strong enough and buckled. After mulling it over a bit, decided to lift it anyways and do the repairs later. After it was stood up, the bent links were removed, straightened and reinstalled. With the tower standing up, it takes almost no effort to furl the sail.

Bent rods.

Getting ready to lift.

Shot of the boat winch.

Halfway there.

Standing tall.

I'm going to let it stand at the machine shop for the next week or so before dismantling and moving it to my house.

In a hundred years or so there will be a lot of head scratching going on trying to figure out if Aermotor actually made a prototype 1/2 size windmill .
Really nice work .
Thank you for sharing .

Still working on little parts.

Stop for the furl lever in the upright position.

Hinge for the furl lever.

Stop for the furl lever in the closed position.

Small parts for the sucker rod swivel. The rod of choice is 3/8" HR. I can build an adapter when I get the rest of the pump.

Need some help here. I searched the For Sale section for "complete pump", the search came back with "Ignored pump (too common) showing results for "complete"."

So I am almost ready to dismantle my windmill at the machine shop and bring it home. I am going to use a 55 gal. drum and some kind of fountain and recirculate the water. The hole in the ground for the drum still needs to be dug and I need to find a "complete pump" to set down in the "well". I have not had any luck with my rancher friend.

What is the correct term for searching for reciprocating pumps and parts that were so common years ago? All I get with Google are submersible type pumps, etc. Any links would be greatly welcomed.
