Hey UDS users.... After procrastinating on getting my UDS build started, waiting for the 'perfect time and design', I am done and ready to just make it. I've had the barrel, used for HFCS, sitting around for over a year now and need has driven me to start it, use it and make mods over time. This is totally against my personality as I like to get it all done and 'finished' before I use it. Ok...all that said.... I have a good idea on getting it usable for a good smoke, but I am curious about a few things... I have noticed on all of the builds I've looked at, the bolts used for the racks are 3" long or longer. Is there a reason for this? 1-1/2" will work easily enough with the 22" weber rack I'm gonna use. If I go ahead and put in a second lower rack, how far down from the first rack should I put it? Most of the charcoal baskets I've seen are 12" cubes or round with the same capacity. If the longest smoke would be a brisket or turkey that would need a max of about 15 hrs is this too big or should I not mess with that tried and true design? Thanks for any help or other tips you mat can give.
