Ah!! The old BS grinder. First saw one of these back in ‘58-’59. Glad to see it’s still around for another generation. Nice project though.

I posted several of these but I think you have a different design yet. Looks like it works smoothly. The animation is cool but WAY beyond my computing skills.

Smoke grinder, is how I heard them called. I like the pop rivet idea~ no screws to come loose.

I hate loose screws. Well, aside from a few old friends.

Good job. These are fun to make and you did a good job.

I made one of these out of left over maple, about 25 years ago, and kept on my desk at work. Every time my engineering manager came to my cubical he would pick it up and play with it!

After a few months he finally asked me what this is, or called, and I told him it was a ”bulls..t grinder”! He never put two and two together and now you know why I made it just for him!

These things never get old!

Made one of these in Jr High shop class over 50 years ago. Teacher called it an air grinder back then. PC was in action there I think. I’ll bet he called it something else to adults.

These are great for the fidgity folks that visit your office. Or, give one to the “Cranks” in your life.

Nicely done!!!
