So I have a solid fuel forge I put together and I am using a hand crank blower. The problem I seem to be having is when I go to start cranking again after working my piece the moment I start cranking again there's a loud yet minor explosion that comes from down in my turyere. I assume that it has something to do with gasses settling down at the bottom of the turyere and when fresh air is added it ignites? Any advice on how to modify my forge or what to add to avoid this?
