I built this 40 cu ft propane kiln using various plans, first from Harry Dedell at Cutter Ceramics, in CT, now long gone, and then adapting Nils Lou’s plans. I rebuilt it twice after first building it in 1975 adding enhancements in every rebuild. At the end it had a culvert chimney with kaowool liners, a car, a separate fiber door on barn door rollers and Advancer shelves.
