« Part 4: Eureka, Grr and Okay Part 5 of Building a Cranky Crane series Part 6: Ready for Assembly »

I need to go out for a small part, but as I set my safety gear on the table I noticed the nice hodge-podge of parts from this project. The only camera I had at the moment is my phone, so apologies for the picture quality.

Yesterday I found exactly what I needed for the hollow, rotating shaft which will turn Cranky’s head. I was thinking I needed a plastic tube of 1/2 inch diameter. The plumbing department didn’t have it. Even the metal tubes they sell to hook up faucets were all slightly bent.

The garden center didn’t have it. I thought maybe something associated with automatic sprinklers might work, but I couldn’t even find that section. They did have bamboo, but it was not straight and nowhere near as regular as the length I already own which is too big.

The electrical department didn’t have it. Every thing was too big.

I found what I needed in the lighting section. There before my eyes I saw the perfect thing! It was rigid, it wasn’t too big in diameter, and it was the right length and right price. It’s a threaded, 6 inch by 1/2 inch electrical lamp part. The package calls it a rod, but to me rods are solid, not hollow. Ah well, it will work. I can thread nuts onto it to hold the gear secure, it will pass below the gear and allow the lifting string to pass through. Things are coming together.
