Years ago, I first saw/played with one of these units a Tom Ferry's shop in WA. At that time, with that machine, you had to remove any rings, and in my case of wearing a fairly large Damascus belt buckle... I had to removed that too.
It appears all the is no longer necessary. I can work with the machine, with my wedding ring on, and the ring never got warm during forging those blades. Likewise no troubles with the belt buckle getting warm. So it appears that over time that issue has been resolved.
Right now I think this Induction forge is going to be just like other tools in the shop.... great for specific types of applications. I purchased a "blade edge coil", and am anxious to try it for differential heat treating. Otherwise its just the sheer convenience of the unit. Plug in the cooler, plug in the induction forge, and you're heating steel instantly. No 30-45 min wait for the propane forge to heat up, and then once the forge is heated up, more time for a workpiece to heat.
