As far as forming expanded metal I used a slightly lighter gauge 3/4" metal compared to the heavier ones typically used as grates. I took a gamble when I ordered my 48 x 48 sheet (because it was cheap) from Amazon as they did not specify them by numerical gauge.
It turned out to be just the right gauge for baskets. I wouldn't use them for cooking grates though...
My fire basket ALWAYS has charcoal in it. It's a big one, but whenever I start a new cook, if needed, I'll just top it off. If not, let it ride.
The beauty of the UDS is the efficiency. When you pull the meat off, just close down all the air vents and it will choke the fire out. Then next time, just relight. IMO, there's just no reason to try and add just the right amount of fuel. Burn it for as little or as long as you want and "turn it off" until next time.
I won't be reusing leftover charcoal but I also don't think I'll really need the smaller basket.
I wish I had thought that part out a little more ahead of time now because I could have used the leftover 3x4 sheet of expanded metal to make two expanded metal grill grates for the drum. I was just thinking about expanded metal grates the other night and wondering if it would be a good idea or not.
Depending on the gauge of the metal it should work. However, I would be careful if it is thin and wants to sag.
I would use at least a 1/4" nuts and bolts with fender washers. After all secured I would cut the excess length of the bolt with a grinder.What size nuts/bolts/washers should I get for fastening together the ends of the 3/4" 9 gage expanded metal? Half inch?
Good going!
Didn't want to use the ash pan I see.
Looks very good.
from JMS: 4. Measure and mark all holes for air intakes, mountings for the internal grates, pit thermometer, and internal meat probes.
Is it just me? I'm going to do my UDS sometime when I get yard work done. At the rate I'm going, that'll be the year 2032.
Why do there need to be holes for the internal meat probes? Cant they just slide under the lid?
Due to potential liability issues most of these local officials are going to be pretty vague about these things and stop short of telling you to go ahead with the burn.
That's my take.
