I came to a conclusion after a couple of smokes on the uds, that the gauge on the outside wall is useless. So, I made a mod to the thermometer.(tossed it out
) Not sure if this was in this thread before, but thought I would share this with you guy's. I took a 5/16 threaded brass rod and drilled a .156 hole through the middle leaving about .002 to .003 clearence ( per side) for the 12 inch thermometer probe($3 at Meijers)to slide in and out as needed.This way I don't need a digital thermometer for the grate, only the meat. And since I haven't made a cart for it yet I added a couple of handles to bring it in and out easier. I made a couple for my buddies and had them pc a copper vien the picture isn't that good I will have to get a better one later. I also did my first butt today on the uds, it's resting right now so no pulled pics yet, but the burnt end was awesome!!
