Hmm. I wonder... would standard "flavorizer" bars work just as well?

Those in particular are 21" long.. (and expensive, but they're just the first set I found.) I love the pizza stone idea but I the more I think about it the more I suspect its going to have way too much thermal inertia to work.. (Wif came up with it, she wants a new stone and figures if she lets me burn this one up I'll get her one :-D)

Yes, that's basically it.. but the angle iron is thicker and less expensive because they are not labeled as "flavorizers" :)
 
I experimented with an 18" pizza screen last week which kept edge to center temps reasonably close, while allowing drippings to hit the coals. I like this set up so far.

(I wanted to add a little smoke to the corn before finishing them off on another grill)

Hey Carbon.. try this for corn.. it works great.

Leave the corn IN THE HUSK. Soak the corn in water for a few minutes, making sure to get that corn "hair" all wet. Then place it on a grill but low heat, or in the smoker. It should take 30-45 mins. The corn will come out very moist. Then just husk it right before eating. It also makes the husk stuff very easy to remove.

Or you can put the corn onto a sheet of aluminum foil, to help further the steaming action. Comes out really good.
 
I think I'm going to try the angle iron trick on mine. I lost temp to 150* after I started up mine for the first time last weekend. When I finally got it back to temp of 225* it acted like it wasn't able to climb on up past that. That was even with 2 of the caps off. And it wasn't producing much smoke. I took the Loin Back rib meat off and put it in my oven to finish up in foil until it was done. At the time I shut it down, closing all the vents, it was finally starting to smoke again. The next morning I observed the juices were on the charcoal and might have contributed to the lower temp that occurred. I was trying to think of a way that wouldn't cut the flow of heat and smoke down in an unnatural way. I think the angle iron diffuser idea is a good one and I have an 18" grill from my old Charbroil bullet smoker that will be a good donor source for the grill to place them onto and permanently mount them. It would help burn the juices in a way that wouldn't possibly slow the charoal heat, and still allow for the juices to evaporate into the smoke for flavor enhancement in the cooking meat

In the first photo, you can see the lack of burn and the juices on top of the charcoal, and the second one you can see my coffee can that had the charcoal dumped into it from the chimney starter. It only used about 2" of charcoal by volume in a 5 hour burn. I believe if I could keep the charcoal packed in a pile towards the center, after the coffee can was removed to begin the minion method of burning, it might actually be more effective. On YouTube, I saw a video that just distributed the lit charcoal from their chimney around on top of the charcoal and that was the minion method they used to start the burn. I don't know which is the better method, center out or top down. I also noted that they used lump charcoal to light it off with. maybe that was part of my trouble - mixing the two in the basket. Maybe using lump to start the minion method which burns hotter (or it seems to be hotter) in starting the other Kingsford.

I have tried putting coals in the middle.. I actually made a smaller "fire basket" to put inside my larger one and I'd put the lit coals in it. But what I have found, is that the best way, is simply fill the big firebasket with un-lit coals, and just pour the lit coals on top, and just mix them around, all over the top. This creates a nice even burn without worrying about any of the coffee can stuff or whatever to focus on doing something special in the middle.
 
Worked on the UDS again today. Not too long though, added the nipples into the holes ( I used 3/4" close) added the elbow for my "up pipe" thingy.
Finalized the green paint, pulled tape from the portions that will be painted gold.
Put another coat of paint on the lid.
The intakes went in quite tightly. As a matter of fact, I had to file out the holes a little bit.
Instead of a 7/8" hole saw I'd use 1" if I were to make another UDS. Even though the nipples were tapered, they were a struggle to get in.

Question-

Has anyone tried to use JB Weld to better adhere the intakes on the inside of the drum? I'm going to try it. I don't want the intakes loosening up and paying a welder costs more than an attempt at JB Weld. (package says it'll hold to 700 degrees F)

Overkill in my opinion. I never welded anything on my UDS. The electric conduit nuts worked totally fine. And say after a year or so if they loosen up, just get another one. The nuts that I found were not exactly identical on both sides. One side the "teeth" kind of bent in one direction. So I "aimed" those teeth into the metal from inside the drum and the one on the outside. Then I just tightened really well and it stuck just fine. Most of them actually don't even touch the metal yet because the whole was tight enough.
 
Hankll, if u can find STUBBS briquets try them with no lump. If you want a good hot fire go all lump with no briquets. There should be no reason to mix them. Drippings on the briqs should pose no problem. It sounds like u don't have temp control down yet. All holes except ball valve are for cource temp control and the valve is for fine control. I can dial in what ever temp I want with mine(and no diffuser)200,225,250,275,300,325,350,375,400,ect just like my kitchen oven.:-D

Rondini... what is your exhaust looking like? Do you have a like a chimney pipe? or do you have some holes drilled in the lid? The good temp control depends on the right air flow. My UDS has three 3/4 inlets and I actually used to have 1 ball valve but I replaced that with 3 magnets so I can have all vents open like half way to let coals burn from all sides more. Temp control is good in mine but it depends on how I exhaust. I actually have multiple exhaust methods built into my UDS from the different variations I've put it through.
 
Did my first cook on it (couple of random chicken thighs I found in the freezer) and it worked out ok. (Overcooked a bit, but still food and -beautiful- smoke ring.) No pics yet.

I think I've got some air leaks. I closed it down around 1:45am, and now (11:15) its still at 205/175. (Vent is still open, bottom is all closed.)

I didn't put in 'flavorizer bars' yet, but fyi it looks like the $5 adujstable-length ones will work if you get 2-3 sets. For anyone who hasn't got a good source of angle iron.

UDS%202_480.jpg

No idea why it woke back up this morning, maybe it was just napping.. (Since its hard to read, the time markers are 9:30, 12:48, 4:00, 7:12, 10:24. Looks like it woke up at 4am and again at 9..)
 
I'm undecided today between caulking up the intakes (to kill off the airflow problems) or ignoring that and getting the stoker bolted in. I closed off all the intakes at 1:45am and it was still running 175F at 2pm today. (I dumped the remaining fuel into the fire pit and it lit back up. So maybe I'll have a campfire tonight :rolleyes:)

I originally put in 1" nipples, but they were way too big - control was either valve wide open and not quite enough, or valve closed/one nipple open and it was too much.. I put 3/4 reducers on them but I think its leaking air. The problem is, I can't imagine where - the nipples are all tightly threaded into the holes and the electricians nuts (inside & outside) are super tight all around.

I'm thinking that I'll do the baffles/flavorizors and the stoker, see if the airflow problem goes away. Got ribs to cook tonight and caulking seems like it'll take half of forever. (Got 400 degree kitchen/bath/plumbing silicone - if its kitchen-safe, it should be food-safe in the unlikely event it comes in contact with food. I hope. And the 4" nipples should keep the temp below 400 - they seem to get warm but not excessively hot.)
 
What valve is this? Did you make it or what?

Inquiring minds want to know...LOL

yes that is made from a bunch of loose hardware - 2 of which are just fender washer and EMT set-screw connector.
 
i close everything when shutting down

I had a thermometer wingnutted into the vent - its out now, it wasn't telling me much that I didn't already know. So when I shut it down tonight I'll close the vent also and see what happens.
 
Hey guess what, I have finished the ENTIRE THREAD From Post 1 to this post!!!

SO, how do I start a UDS? Just kidding.

There are so many options of builds and so many of you have built some nice smokers. I'll be starting on mine soon. THe only thing that is for sure, I have yet to make up my mind. Thanks to everybody who has posted here with an idea or solution. This place is the best.

After 5 days of reading this thread. I really farking hate it!!!! LOL
 
Paint

I got a question for those of you who have painted your barrels. Mine is in really goog shape with nice paint, gonna do a small burn this weekend as the only thing inside my barrel is the rust proof coating and its already starting to rust so will like I said a small burn. Can I just sand rough up the original paint then use a primer and a high heat paint or will the original with sanding peel.
 
I have tried putting coals in the middle.. I actually made a smaller "fire basket" to put inside my larger one and I'd put the lit coals in it. But what I have found, is that the best way, is simply fill the big firebasket with un-lit coals, and just pour the lit coals on top, and just mix them around, all over the top. This creates a nice even burn without worrying about any of the coffee can stuff or whatever to focus on doing something special in the middle.


Ok, good to know.....I will try the top down minion method and forget the coffee can in the middle to start a minion from the center out. I kinda think it will stay lit better, going top down.

This was my first time to try this with my smoker and my smoker wasn't done. I still want to add the ball valve on a stand pipe at least half way up the side of the barrel. So temp control is an issue for me simply from a experience level.

I'll check around for the Stubbs, I don't recall seeing it in any stores I frequent. I'll do a search and see if I can see if any stores might be listed as carrying it in my area.

Unless existing paint is high temp paint, even a small burn will scorch/peel it in at least some places. You just as well count on removing it all and then repaint according to the high temps mfg directions. The kind I used recommended against using any primer.
 
Seach
Rondini, Could you elaborate on your Temp control for each temperature listed. Like when do you close which valve and how much openings you have? Thanks in advance.


Seachaser
I open everything at start up. I use sheet magnets and 1 ball valve. I have 2 short stem thermometers just below my 2 upper grates. Depending on the temp I want, about 15 min after start up I start closing the magnet holes to get to and hold the temp I want. When I'm close to the temp I adjust the ball valve. This hole process takes roughly 30 min. After each adjustment I wait 5 min. REMEMBER, it's easier to raise the temp than it is to lower it. My thermometers are app. 50* cooler than center of my grills. If you haven't gotten yourself a note book yet I recommend you do and use it to track what u do on each cook. Every UDS is a little different on how it cooks. It took me awile to get a feel for how closing up 1 hole affected the temp, how 2 holes closed did it.
I hope this helps, if you want to pm me feel free.:idea:

I just use the large Bung hole that was in the lid when I got it.
I have a pc sheet metal with a bolt, nuts and a spring, for closing off the chimney when I shut down after the cook.
I have smoked at 200* all the way up to 450* using just 1/2 of the diameter of my basket app. 1/2 full. I add app. 1/2 chimney to that half when I smoke. In my UDS having only 1 hole open still gives me an even burn. Also, I dump my lit coals on top of the old dead coals and have no problem getting my temps or with the taste. I don't have any other exhaust method. I did set up my UDS to smoke and grill. I don't remember when I set the basket up that way, and I've added no other coals than what is in my chimney starter.:idea:
I hope this helps. pm me if u feel a need.
 
Another option is royal oak - most walmarts have it, and it seems popular with the competitors out here. I grabbed a bag for the seasoning burn and it worked really nicely - more even sizes than most bags of cowboy and it burned forever.

I've used Stubbs but all I remember about it was that it seemed expensive. (Although now that I look online.. pound for pound, its cheaper than RO by just a bit.)

On a side note, anyone use a rocks stoker on a UDS? Seems like it overshoots really badly whenever it runs the fan. I had it set to 230 (green dots) and it'd come on around 210 but by the time it cut off the UDS peaked around 280. Thats .. thats just not good.
