In addition to tightening up the exhaust ducts and adding some height to the external exhaust chimney, I'm going to increase the exhaust port size and possibly play with the riser height....one of the advantages of the removable top. Clearly there are better riser materials and designs for longevity and I hope to incorporate that in a final design. In addition, I'm just going to play temporarily with the idea of adding fire-brick inside the stove to take up some of the CSA and thereby perhaps create a narrow L-shaped burn chamber. [Biggest problem with that idea is that there is no insulation as is usually seen in cross-sectional drawings of the burn tunnel.] Easy enough to do as a test at any rate. I'll try to remember to take photos of a burn-in-action next time to see how things are progressing. Thanks again for great comments!
