I saw them on Alibaba i think he buys a lot of PE gear overseas and marks them up but i don’t know.Anyhow contacted a couple of metal shops in regards to making the circle device to Tungsten but no luck no one wants to touch it for some reason.
You’re exactly right about MOS, he generates his income with affiliate marketing.
As for finding a machine shop that will take on prototype projects….
Most shops are production oriented. They don’t want to mess around with onesie - twosie projects. The vast majority here in the Seattle area won’t even talk to you because all they do is aerospace work. Most shop rates start at $150 - $250 per hour depending on the equipment they intend to use to manufacture with.
I’d suggest you find a small one man. Someone who’s a sole proprietor.
Tungsten is difficult to machine. It’s very hard and can chew up tooling very fast.
