as my pics show i did some mods to my snp, to try and control my temp to a more steady reading and also to use less charcoal i did find a "grate" at HomeDepot for the fire box i wanted some thing with smaller holes to keep the coal up longer and too burn more of it before it dropped to the bottom. i did have to cut some of the ends to make it fit but it works great . Next i used the "plate" method in the bottom of the smoker and the deflector to "push" the heat down and across to maintain heat from one side to the other. I did use a lot thicker metal at 3/8 of an inch , it did take longer to heat up but once it got there i had no problem keeping hot and close to the 210 to240 i like to smoke at. i would like to thank everyones input about the mods to the snp and i learned a lot !!!!! i have pics to show !!! thanks too all, especially Rivet !!!!!
