New to this forum and just finished making Paul's Ostrom's design for the UDS. Pretty simple but I do have a couple of questions in regard to the build. The only thing that was deviated from the plan was mine has 2" feet instead of 1" on the ash pan which puts the lip of the ash pan @ 2 1/2" above the intakes which were drilled per specs @ 2" on center. My first question is will there be sufficient air flow with the intakes below the ash pan? Even with the original design of 1" legs on ash pan the intakes are about 1" below the lip of the ash pan. Am I looking at the engineering of this wrong. It just seems that the intakes should be more at the level of the actual fire basket and not under the ash pan.
My second question relates to the first one in that because I have 2" feet it leaves only 22 1/2" between the bottom of the fire basket and the cooking surface of grill instead of the desired 24". I lost the 1/2" somewhere else within the basket. If it is a major deal, I can always cut the feet down to 1" and get 23 1/2" between surfaces.
I'm looking to do a test burn tomorrow so input is greatly appreciated.
