paul just a few days ago someone was showing ahopper full of logs : You responded th Crispins comments about a tapered hopper for presimably feeding chips into the stove. Is it so hard to conceive of a tall vertical feed tube with a slow bend into the combustion chamber, sealing the open end to prevent air feed as well-- to prevent turn, back burn up that tube .
