just joined this site a couple days now. I'm a casual smoker living in hawaii but would like to get into it more. I am currently using a brinkman standup smoker which I put over a gas burner. I use a small cast iron frying pan to put my wood chips in. I'm also building a little bigger smoker out of a metal locker like the ones in gym class. I'm also planning to use a gas burner for my smoking in this one. When smoking my meat I usually have to add wood chips every 20-30 mins. over the course of 4 hours. Any suggestions on how to do this without having to check every half hour or so (longer smoke times between chip replenishing?)
