My partner is a professor of ancient philosophy. We were trying to think of a joint project combining his work in Philosophy and my Glowforge. We came up with #gnomelithic.
He is translating thoughts of Ancient Greek philosophers, and I am engraving them onto rocks and leaving the engraved rocks out for folks to find when we go out for walks.
Thanks @cmreeder for the settings (Settings for Gravel )! I ended up using 300 speed and 100 power for engravings. Quality depends on composition, flatness, and color of each rock. Rocks are found in my yard.
I like these a lot. I bought a bag of river rocks at the dollar store a few months ago and have been meaning to engrave them. Guess I need to decide what I want to say!
You can buy bags of them from any of the crafts stores (Hobby Lobby, Michaels, etc). Grab 'em and engrave whatever - even just a “Hi there” will put a smile on someone’s face when they find it amongst regular stones.
I gathered about 10 lbs of nice flat river rocks while I was dirt-biking, and stuffed them into my camelbak. They were bouncing and slamming into my back the whole ride home. I figured it would be worth it.
They don’t engrave well; barely even take a mark at all.
