Just a few pics, if anybody was interested. I've not been completely happy with the time it took to get the lump up to temperature. I seen something like this in the internet and thought I'd try it. I put a 5 inch vent pipe on a 6 to 5 inch reducer. I cut it off at 23 inches. I bent the sharp edge at the top over like you would see on a rolled over rim on a paper coffee cup, using a few rocks in place of anvil and hammer so there are no cut hands. In theory there should be an increase in draw, etc.
