I've seen Grant Sarver's youtube videos, and especially the ones where he uses the Induction Forge. That Unit is Chinese made, and it seems to work very nicely!
If you look further, You might find similar demo videos by Mr. Mark Aspery, too.
I have tried unsuccessfully , to inquire as to who might sell this machine, (Centaur Forge?,.... etc.?) No one seems interested, or bold enough to respond, or reply! What might be the problem?..... Surely, SOMEONE must sell this unit here in the USA!!!!!....
The one USA company that I've found that does sell this, is one based in New Jersey, called "Across International", an Industrial machine import company (?).
If ANYONE Knows of a Blacksmith, or Blacksmithing Supply Company that would like to sell some of these types of machines, then, PLEASE post/say something, as I'm NOT the only one out here that would LOVE to own one of these machines, or something that is tailor-made for us Blacksmiths/Metalsmiths/Bladesmiths!....
