My projects name is the pen shaker.I made it for a 7th grade project. I got an a++ on it. It is the first project I had ever made. I used a old bearing from a lawn mower pulley and cut the wood gear from 3/8 plywood using the frill press and band saw. I have made more projects and I will be posting them on her.

OK I give up…...what does it do? Since its called “pen shaker” I’d say its some kind of duplication writing thing-a-ma-gig? OR could it be something that shakes up a pen to get the ink flowing when it stops writing? Could it be a whirl-e-gig?

Nice work… keep the projects coming…

Yeah, me too. What does it do? It has a nice gear wheel, and a propeller fly wheel. It has a bearing. So, is it a whirligjig, a noise rattler, or a weed-wacker? Doesn’t matter… looks like you had fun and enjoyed making it.

well done.

My guess: it appears there is a pen inserted in the crook of the tall S-shaped piece at the right of the first pic. Turning the crank spins the “S” and centripetal force pushes the pen’s ink toward the nib. Clever idea!

It’s somewhat Rube-Goldberg-esque in that it’s a complex, awkward contraption intended for a simple task. As an engineer, I wholeheartedly approve!

Here is another “pen shaker.”

Sure beats shaking a pen by hand. I mean, my arm is already tired out from all the shaking it took to get my pen to write this one sentence!

I expect a lot more projects in the future, so get to work!

You hit it on the nose… you put two dry pens into the S piece and then crank it. Then the centripetal force makes the ink flow down the shaft and makes the pen work again. I was really surprised that it actually worked and my teacher was very impressed when I was able to answer the questions that the class had. Thanks for all the comments!

I need a keyboard shaker. My computer screen is running low on ink.

By the way…my favorite wood projects are the ‘gadgets’...the ones that do something. Nice job!

Young Blood – great to see up and coming Lumberjocks. Your project and grade for it should have made you AND your parents very proud, Well Done!

Working gears don’t have to have a purpose – it’s cool just to watch the mesh and rotate. I look forward to seeing future projects.
