Slowly but surely, I am making progress. Made a bit of a valve control with PVC, still too much air but it was better than before. Unfortunately couldn't find anything like what Jasent had. Any recommendations for lubricating the PVC Valve? I was told to not use oils such as WD-40. Still need to add clay to the fire bowl to make it more rigid. Also need to make a bit more of a cut in the body to get the tuyere deeper. Overall I feel like I am making progress. Thanks for all of your help everyone!
