Paul McC Posted June 6, 2022 Share Posted June 6, 2022 Hi there, I new to the hobby and just made myself a coffee can style mini forge to do some heat treating with. However, when I lit it to see how it would go, I was confronted with a rather obnoxious fog horn like humming. I have attached a video (if it loads properly) that shows the forge and the sound. The video muffles it a bit, but it is a rather intense noise. Could someone please help me to figure out what I have done wrong. The forge is a closed back type, I wondered if that might be the cause but I have seen a few videos online that were closed backed and seemed to work fine. And I didn't want to cut a hole in it if I didn't have to. I wasn't sure if it would be more effective this way or not. Whether or not it is relevant, I made it with a mix of vermiculite, perlite, sand and cement. 2/2/2/1 ratio. With the option of coating it with a layer of refractory cement if I need to. It is 12inch long 8 inch wide with a internal hole of 10 inch by 3.5 inch. And its run with a basic map/propane canister burner. I would appreciate any advice anyone could give me to address the issue I am having, Thank you. 20220606_192153.mp4 Link to comment Share on other sites More sharing options...
