Also how does the USD hold Temp lets say 225 How many vents do you need? I'm thinking 4 around the btm of the drum. What do you use for a sealant?

Instead of ball valves can you put vent on the btm of the drum?

Do you need to have a gasket around the top?
Here is another UDS thread. First post is a decent tutorial

Don't bother with the hole cutter - the step bit works fine for the 1" hole (harbor freight is your friend for cheep step bits). Don't bother welding it - use conduit nuts, they will thread on the nipples just fine (one on each side will tighten things up nicely). You may not even need them (YMMV), but I did.

If you use dry charcoal - usually you only have the caps removed to light the fire, and work with a fraction of one hole (the one with the valve) to fine tune the fire. If you charcoal is at all damp, you will probably need to remove 1 cap as well.

Generally a full basket of charcoal will give you over 14 hours of burn time - which is enough for pretty much any bbq. I have probably done somewhat longer by cooking multiple meals on the same burn (my record was almost a 24 hr burn - lunch (burgers), dinner (pulled pork and abt's), then an overnight brisket for lunch the next day. My set up is different though in that I am VERY frugal with my charcoal. I have a single centered and baffled intake that is attached to a fan and a digital thermostat. This is my second UDS, the first was fully traditional.
