Well , this UDS has been a learning experience for me to say the least. There are a few issues that I will just live with. I didn't double check how level my holes were for the spots that hold the grate..it is a little lopsided but not too much. The 3/4'' pipe is a little slanted for the air intake, but it still sucks air in. The lid doesn't make a complete seal , but I'm planning on trying to find some stove gasket to help it out. Lowes doesn't seem to have it in stock. My next project will be to add beer bottle caps around the barrel with magnets inside of the caps. If i was to go back and change something, it would be the exhaust. Going with magnets around the top is such a pain in the a$$. My lid didn't come with a big hole on the top, but next time I will make one big exhaust. Please excuse the mess on it, I spilled coffee this morning on it, and left some marks from handling it after the pork butt went in.
