Hello ,I just finished my uds This is the first one i have build. Im in the seasoning stage. .i am having temperature control problems.I have a standard open top drum with a Weber lid .It fits well.I installed three 3/4 intakes ,two with caps the other with a ball valve with 30 " extension.All have been RTV high temp sealed around the outside.My coal basket is 15" across by 12 inchs deep.with 3" feet. made of mesh. I started using the minion method with 10 coals.with about 10 pounds of unlit.I'm using Kingsford Oringinal .I started the 10 coals in a chimney , let ash over.Then i dumped them in the center. I put on the lid ,All temps was taken with the lid thermo,until i get my other one in. I capped the first valve at 190. then the second at 210. and closed the ball valve to half.The temp keep climbing. After about 30 minutes the temp settled at 260. So i closed the ball valve a little, Waited 30 minutes. The temp never moved . So i closed some move , Waited checked again , went down a little. repeated to try and get the temp down to 225 . with everything closed the temps riding at 250 steady for 2 hours.The thermometer are calibrated with boiling water. I need to get the temps down , i don't know what else to do . I post pictures in a few.Any suggestions . Thanks Sam
