Yes he did. some were pretty elaborate, about the size of an upright laboratory model. They were a big flop. Heavier than h*ck and the lids and doors tended to fall off. I don't think they were ever offered for sale to the general public but I could be wrong. I also don't think a complete one survives.De Soto Frank wrote:wjw wrote:Edison should have put a steam engine in those crazy Diamond Disc cabinets he made with portland cement!
