Wanted to post a few pics of my UDS. Completed it in April after reading this thread. Now I just have to find the time to use it more and learn to perfect my skills.
For an ash pan I ended up using an outside exhaust fan cover made from aluminum. My brother works for a sheet metal company and got me one for free. Its four inches deep and will hold a A LOT of ash with out clogging the vents. A cheap Wal-Mart kettle lid from a dead BBQ was also used along with the hinges. have almost $100.00 into it so far.
