I made this UDS out of 20" Caseing. I cut the caseing down to 3 feet, but it was 4 feet long and weighed 230pds.
I think its around 200pds now.
I am going to burn off all the protective covering.
I used 3/4" threads and brass ball valves for the airflow on two sides, then just one open 3/4" thread on the back.
I have two racks and a 12" tall charcoal basket. I think I'm goin to have to make it a little smaller.
My carrying handles crack me up, maybe a little over kill.....on everything!!
