I have a WSM, but wanted a Mini for travel with my RV. After reviewing posts by the Kevinator and others on WSM mods, I modified a SJG, using a Chinese IMUSA 32 qt Tamale Cooker, purchased at Wally World for $20. Total time after gathering the material was about 1.5 hours.The top of the cooker is an exact fit to the SJG lid. I used foil folded around the bottom edge to get a tight seal of the bottom. The Cooker is 13.5" high and I cut the bottom out of the cooker, using a skill saw, being carefull not to cut into the curved edge of the bottom, staying at least 1/2" from the edge. I then attached 4 L shaped aluminum hangers on the inside, 9" from the top. I used a 12" ceramic planter base, foil wrapped, rather than a water pan. Then, I cut the ends out of 3 small evaporated milk cans, using the cans as a spacer, sitting the cans on top of the ceramic base, placing the grill on top of the cans, it is a tight fit. For the charcoal holder, I raised the grate about 1.5 inches, using aluminum crossbars, screwed together in the center, bent on the ends, wiring the grate to the top of the bars. I have found that 1/2 to 2/3rds weber chimney using Kingford, is plenty for a 6 hour cook, at 250 degrees. Temp controll is fairly easy, but the side vents on the SJG are not real tight, so it is difficult to keep at 250 if using more than 1/2 chimney. I used the Minion method, putting down a base of unlit Kingsford, piling 20 lit briquettes on top. It is up and running in less than 15 minutes at 250. It will maintain 250 degrees for hours, with the vents almost closed. Total cost, including the SJG($29.95 delivered from Amazon), glazed planter base($6.95)and aluminum for L hangers, was less than $60. I elected not to paint the tamale cooker center section, it looks "purdy" Carefull with the amount of smoke wood, 1 medium piece is enough with the small area.
