Fired up the forge last night

I tried heat treating the ulu blade I made last night and broke it. I made a ulu blade tonight but don't like it. I tried to do a hammered texture on it.

I did forge my garden knife concept tonight. I am quite pleased with how It turned out! I spent some time with it on the grinder and got it close to done.

Savonious VAWT windmill aquarium pump prototype

I made a Vertical Axis Wind Turbine today. It was supposed to pump air, but never quite got that far.

The idea came about from a discussion on a website I am on about aquaponics.

Yes, I made an indoor windmill. Stop laughing. Please. No, really, stop laughing!

I am using the air coming out of a heat vent to test the concept as it’s a bit cold outside.

The air pump isn’t getting enough power to actually work, but it does prove that the concept should be able to be made. I blame the flimsy soda bottle. I had a hard time to get the curved bits to flare evenly. I used a lighter to heat the plastic a bit while I had positioned it where I wanted it. One half would work, the other doesn’t. Weirdness. I also used a bit of excess cat5 wire to hold the thing together. Not quite baling wire, but the tech-age equivalent.

The pictures are kinda hard to see what’s going on. so I made a video too.
