I was given my Smoke N Pit Professional and I went and done the following mods, added to the smoke Stack to make it grill level, added a Baffle between fire box and Smoke chamber, built a new charcoal Tray with sides, put in a new Temp gauge (in original Hole) , I put RTV silicone and rope seal to seal the firebox lid, I still can't regulate the temps, Today I smoked a couple of Fattys' Started with a 3lb coffe can of Hot Coals (BGE) and piled unlit around it, Removed the can, Temps went up to 235-240 with the door damper shut stayed there for a while, Would Cool down until the coal dies down The lid that was nice and tight before I started the fire had a big old gap.. So I weighted it down and sealed it up again, Has anyone welded the lid shut on a SNP ??? I'm about to buy a new unit and have been looking at either a ECB or a Verticle for Around $130 Anyone have any opinions or suggestions??
