Saw recent build by rabbithutch http://www.smokingmeatforums.com/t/121337/heres-my-mini-wsm-build-longish-with-qview  and thought I just had to do one of these.  Read hours and hours of posts and different ways to build this thing. Finally settled on this plan.

Searched my area for the Imusa or Vasconia tamale steamer, no luck. So from what I have read the Vasconia is consistantly a better fit so since I had to order I went with it. 38 bucks from Amazon, free shipping though.

Like rabbithutch I wanted more options on grate position. I wanted a deeper grate for things like beer can chicken but did not see a need for the one at steamer height. So I settled on the diffuser height no higher than the ridge for the steamer insert, bottom rack at the insert ridge. On the Vasconia the ridge sits 9 1/2 " down from the rim. 4" down for the first rack then split the difference for the middle (2 3/4"). So my first rack is at 4" down, second at 6 3/4" down and the third at the steamer rack ridge 9 1/2" down.

So here we go.

Cut the bottom out of the pot.

Most of these builds I have run across use 1/4" bolts, seams like overkill to me. Went with stainless steel 10-24 x 3/8 machine screws with lock washer, flat washer and acorn nut, fit perfect, looks good. Just a note, I have run across a lot of threads with guys trying to do this build on the cheap, if so forget the ss acorn nuts they are proud of those, over a buck apiece!

Mask her up and paint

While paint was drying:

bent and drilled lower vent flange for cariage bolt handle.

Did upper vent too. Will pretty them up later. found some knobs that looked good at ACE but over 3 bucks apiece, ouch! I'll come up with something.

Found a SS pet food bowl at one of the local farm and ranch supply stores for $2.99. Fits perfect for an ash diffuser, sold. Drilled 8 each 1/2" holes around the base. Interestingly, when I did the math on area, the 8 1/2" holes have about .2 sq in less area than the 4 3/4" holes in the damper. But I figure the damper is going to be pinched most of the time anyway so it should not be an issue.

Since I will be using mostly briquets, from what I have read I thought a basket is in order.

With the Vasconia pot, a weber 18 " charcoal grill is just a tad too big to go around the ridge for the steamer insert, unless you use a little force, it will pop right through. Weber P/N 7440. foiled up saucer and we are there.

Mounted this way I was only able to get about 3 1/4" height on my charcoal basket. Some guys in threads are talking about 4" high baskets when the diffuser is at the steamer insert height. Will see if this impacts cook time much.

Minnion method, loaded basket, took out six briquets and got them lit, couple chunks cherry wood.

Getting dark.

So far looks good, temps leveled out, holding good, ambient temp about 90 deg.

I think I'm gonna like this.

Update: about 3 hours into this thing and the the temps are holding real consistant. Don't have to mess with it at all. half a rib cook, lookin good.
 
WOW!!!!!!!! Looks great !! Like you can't find the pot around here. I need to get off my butt and order one on line.
Will copy this post to my "evernotes" file. That way I can use it for when I start building mine
 
Wow, this thing is impressive.

11 1/2 hours later:

Really haven't touched the damper the whole time, holds temp really well.

I originally wanted this as a portable smoker for camping but it looks like this will be real handy for small everyday smokes also.
 
IronHorse07, Howdy;

Several questions (my brain processes better watching than trying to assimulate from reading and viewing pix), so I ask questions hopeing that I can make

some kind of relevelant guesses...

1.) How much of a lip did you leave on the pot's bottom ?

2.) How tall is the ash/air inlet bowel ?

3.) What size expanded metal did you use ?

4.) Did ya just 'shove' the diffuser grate into the bottom, ... that what your sayin' ...?

5.) Have you tried any lump in there since you first fired it up ?

6.) If you have, which do you think works better ?

Thanks for taking the time to answer. I do like what ya did with the place...

1.) How much of a lip did you leave on the pot's bottom ?

I cut out a 12" diameter circle which left about a 1 1/4" lip. However, I used a 12" terra cotta saucer and with the grate sitting on the lip and the diameter of the saucer there was not enough area around the diffuser when the smoker was loaded. The thing would come up to temp just fine but when you loaded in a thermal mass the temp would not come  up above 160 or so in the smoke chamber no matter how hot you got the bottom. I have extra cooking grates so the simple short term fix was to lay a grate on the lip and put the diffuser on that grate, worked like a champ. My schedule has been too hectic to do much lately, but the long term fix is to either cut more of the lip off or us a 10" diameter saucer.

2.) How tall is the ash/air inlet bowel ?

The bowl I found is a small SS pet food bowl, it is just short of the charcoal grate. The store I found it at also sells the Smokey Joe so tried it out there, fit good.

3.) What size expanded metal did you use ?

1/2"

4.) Did ya just 'shove' the diffuser grate into the bottom, ... that what your sayin' ...?

Yup, on the Vasconia pot the Weber 7440 grate is about 1/8" or so smaller than the diameter at the lip, with the grate you will get a little flex in the rim if you go parrellel to the grid wires, you get some flex if you push in the center of the grate, some flex in the pot itself, popped right in.

5.) Have you tried any lump in there since you first fired it up ?

No, I have not. So many sells lately on Kingsford I got a bunch of it around.

6.) If you have, which do you think works better ?

Thanks for taking the time to answer. I do like what ya did with the place...

Great job on the mini-WSM, Ironhorse!
I guess I missed this when it was first posted. You did a much better job on yours than I did.
When you said that you held temp for 11.5 hours, was that on the one load of briquettes? What did you use?
Thanks, yes it went for that long on the first time with it, however that was on an empty smoker and since then I have learned there is a difference, how much? I have not had the time to play around and find out yet.
 
Update: Took the time to fix the heat issue when the smoker was loaded. When I actually measured things up I was in error in my previous answer, I had only cut out a10" diameter hole in the bottom of the pot. The flat on the bottom of the 12" terra cotta saucer is 10 1/2" dia. So cut out the hole to 11" dia., took about 10 minutes. Haven't tried it out yet but if it is not enough I'll cut out another 1/4" all the way around. Also added a couple of therms.
