Hi to all Have abandoned idea of using a busted w/machine as a smoker as i just picked up a near pristine 55 gal. drum for 20 bucks ( no lid). I am looking for input/ideas on the build. Being a retired engineer ( sorry about that) I like to write down a " design requirements spec." before starting design. Here is my first draft. Please bear in mind that I live in the tropics. Primary heat source: electric element w. contol Back up heat source: charcoal/propane( will probably put drum on 6 inch legs so I can slide another heat source under the drum.) Smoke Daddy Kahuna for smoke Water pan to stabize temps. Drip feed/drain iced water supply to water pan for cold smoking. One piece 3 grid rack unit raised and lowered to/from drum with light block and tackle. Hinged lid cos I am old. Easily cleaned by filling with soapy water and draing.( after element removal) ??????? Any input would be appreciated. Thanks.
