Panhandler, Did you make the hopper extension or have it made? Could you post pictures? Thanks.
I made one myself in the shop at work (on my own time, of course
). I welded a heavy gauge sheet metal box (I work in a galvanizing and aluminizing plant) the same size as the top of existing hopper. I then welded in a flange inside the box to match the top of the existing hopper and the same for the top. Then gave it two coats of black stove paint. I used high temp orange RTV between the original stove hopper and extension and sheet metal screwed the flanges together. On the outside of this joint I used black RTV for looks. Then used some "donated" gasket material to the top flange fixed with RTV and installed the original hopper lid.
I understand Mr Holton's concerns. I have worked with NG, hydrogen, etc for years. Our furnace at work has a hydrogen atmosphere. A guy on iburnpellets forums had a local welding shop make his. I felt that I needed the hopper extension because I sometimes work long hours and now both my sons are away at college. It sucks to come home to a cold house, and it's worse to come home and hear the furnace running.
