I had always wanted to build one of these since reading the thread created by UnaBiker. Below is a link to a short video of the machine in action. Seemed to eliminate about 95 percent of the the dross from my freshly cut plasma parts in about 1 hour. For media I just used some lava rock and gravel I had around the house. My question is if all I want to do is remove the dross what type media would be best? I was going to try stainless screws for media next thinking I could run it dry. Next I will spring for some cermic media and add fluid recirculation.
Thanks for any advice
