There’s a guy on youtube- clickspring, who made a replica of it, and used a lot of homemade tools that could have been available in ancient Greece. I don’t think he strived for 100% accuracy, but it definitely seemed like he put some thought into how such a device could have been built in the ancient world.

I’m certainly no archeologist, engineer, watchmaker, etc. but it left me feeling pretty convinced that such a device could be made to work with tools and techniques available at the time.

I think he had it spread out over about 12 main videos probably about 15 minutes each, give or take, so it’s a bit of a time commitment to go through them all, but I found it pretty interesting.
