One more.

This is the comp/wood or plastic wood ganny base with the hole cut for the bearing.



This is the hole cutting tool.

This is the bearing being inserted into the hole.

Here is a complete tape drive wid generater. Its been flying for a while. Its a littel rusty but still yaws just fine.

On some I just cut a square of sheet aluminumto keep the bearing in place. On this one I use some laminations from an old ac motor. It was the right size to hold aganst the retainer ring on the bearing.

This yaw bearing is great for tape drive, tred mill and up to 1.5 hp motor conversions.

The bearing has a 1.75" bore. The EMT electrical conduit I use as mast is 1/16" less.

So the fit works quite well for this aplication. Been fly 20 units for sevear years no problem.

This is the bearing that you get at Lowes?

On some I just cut a square of sheet aluminum to keep the bearing in place.

I'd be inclined to use a piece of galvanized sheet iron.  A steel/steel junction has less tendency to galvanic corrosion than a steel/aluminum junction, and galvanization exists explicitly to coat the metal with a sacrificial anode to preserve it for years in wet environments.

One of my sites is near the ocean, where corrosion problems are greatly exagerated by the salt in the air.  (And I grew up in a state where they salt the roads.)  So this might not be as much of an issue where you are as where I am and/or have been.  Nevertheless, if you have any mositure at all, even dew, you'll reduce your corrosion by picking the metals appropriately.

Hi Dr D.

No this bearing comes from Applied Industral Technologies. Used to be Bearings Inc.

Its chineez. Around 20 bux. The bearing has a 1.75" bore wich fits the EMT I use for mast. The EMT measures about a 1/16" less OD. Other bearing suppliers should have the same thing?

The bearing from Lowes has a 5/8" bore. Its for motor shaft use.

These pics are really helpful, but I've run into a snag. I'm in south eastern Ontario and I tried looking every where for these bearing. The biggest I found was 5/8. This is too small for me. I need 1 1/2. If anybody has any ideas where else I might get one of these or a different set up all together. Another problem is that when I'm looking and people ask what I'm using it for and I say a wind tubine. They usually look at me like I'm some kind of freak. ( I am a little but they don't know that)
