For those of you who don't know us or haven't seen our cooking set up at a competition, we are an all WSM team. With the exception of our first event at Lake Pleasant in 2006 where we used a Weber Kettle and a Bar-B-Chef offset, all of our cooks have been done using 4 WSMs. We used the same 4 cookers for the 2007 and 2008 seasons and the wear and tear of all the travel, loading, unloading and being jostled about in transit finally caught up with them and the most polite way of putting it is that they're not what they were when they came out of their boxes two years ago.
That being the case and knowing that Weber had redesigned the 18.5" WSM as they rolled out their new 22.5" WSM, we decided that we should invest in a new set of cookers for the 2009 season. We decided to go with the 18.5" model instead of the 22.5" model mostly because of space concerns needed for transit. There were a few other considerations but space was the primary concern.

Last week I was browsing at Amazon and saw that they had dropped the price on the new 18.5" WSMs down to $259 each with free shipping from their normal price of $299 each with free shipping. That was all we needed so we "pulled the trigger" and ordered four, three of which arrived yesterday. Now that you have the backstory, on to the review...

Parts & Assembly
If you've ever purchased anything from Weber, you know that their products are extremely well packaged for shipping and this item is no exception: Lots of bubble wrap and cardboard bracing inside to protect the contents. The parts are well packaged and easily identified. All the nuts, bolts and washers are in a single package, the legs and grill brackets are in a box and most of the remaining items, including the door, are wrapped in either plastic, paper or bubble wrap. Assembly instructions are simple and the cooker will take less than an hour to put together with only a screwdriver and a wrench needed to do the job.

Initial Comments Upon Completion of Assembly
The first and, in my opinion, best improvement over the old version are the legs. The new legs are almost twice as wide as the old legs and they flare out slightly, maybe 1.5"-2", giving the cooker a much more stable platform. They still attach to the charcoal bowl the same way but the new version also includes a "heat shield" which rides between the three legs and about 2" below the bottom of the charcoal bowl. The heat shield is really nothing more than an ash catcher tray from a 18.5" Weber One Touch Silver grill and it attaches to , well, more like "rests" on, the legs via three notches. It will easily pop out and doesn't provide any added stability to the platform. I've left it on for now but I can't see it lasting there for very long. (Meaning the first time it pops out of the notches is when it comes off for good!) The rest of the bowl portion of the cooker, including charcoal grate, charcoal chamber and lower vents, are all identical to the older model WSM.

There are two significant changes to the middle section of the cooker, those being the door and the water pan. The new door has an oblong handle instead of a knob which makes it much easier to see the correct position for both open and closed positions and there are a series of tabs in the bottom of the door which helps to keep the door from falling out of the cooker when opened. In fact, it hangs in at about a 45° angle which is great for peeking in or when needing to add a chunk of wood to the fire. The water pan is shaped like a smaller version of the charcoal bowl meaning that it is much deeper than the old style pan which is much more shallow. The pan will hold a lot more water but will also ride much lower/closer to the fire. I've always recommended wrapping the outside/bottom of the water pan in a layer of aluminum foil to protect the finish and to make clean up easier and the new bowl shape will make that job a bit tougher as a single sheet of wide foil will not cover it completely. This is a minor thing but one worth noting as the water pan is often the most soiled portion of the cooker after use.

The only change in the dome lid of the new 18.5" WSM is the addition of a temperature gauge directly opposite the vent. It's mounted into the lid through a pre-drilled hole and fastened down with a wing nut making it easy to remove and to keep clean. The bad news is that it does not appear to be very accurate. I haven't removed it and tested it in an ice bath or boiling water yet but I did insert the probe from my Thermapen into the vent opening, positioning it at the same depth as the stem of the lid thermometer and the reading was off by over 40°F, meaning the lid thermometer was over 40°F lower than the reading on the Thermapen. I plan to test the lid thermometer on the next cooker I assemble to see how it fares in the aforementioned ice bath and boiling water. I also want to see if they can be calibrated. If they can't, they're pretty much useless.

First Cook - 1/2 Chicken
What good is having a new cooker if you don't use it right away? We needed to do a practice run on IBCA 1/2 Chicken for the upcoming competition in Tempe and this seemed like a good initial test. I had already installed the extras I needed to attach my Stoker to the WSM so all that need to happen was to fire that sucker up! I don't plan on going into any details of the actual chicken preparation but rather intend to focus on the performance of the cooker.

The first thing I noticed was how tightly the cooker fit together at the intersection of the charcoal bowl and the center section. There were no gaps and I saw almost no smoke escaping around the seam during the cook, even with a 10cfm fan blowing air into the system. There was also little or no air leaking from the closed vents in the charcoal bowl.

The door fit pretty well on this cooker in the "handle at the top" position with only a small amount of smoke leaking out when the Stoker fan was on. There was no smoke leaking out when the fan was off. I always ran my old WSMs with the knob at the bottom as there always seemed to be less air loss that way. That doesn't seem necessary anymore. Also, the new oblong handle is a great improvement over the know and the clasp on the inside is also of better design and larger than the old style. The only thing I might do is add a layer of high temperature gasket material around the inside of the door just to make that seal as tight as possible. It isn't a necessity but will certainly help make the cooker as air tight as possible.

On to the dome lid. If you've used a Weber Kettle or WSM brand new out of the box before you know that the porcelain coating on all the parts makes for a pretty slippery seal. The dome lid and the center section of the cooker never seal up very well until there is a good layer of barbeque gunk (sorry for the highly technical terminology) on them. There was a lot of smoke leaking out of this seam even though the lid and the body matched up well. I know from experience that this will become less of a problem after a couple of cooks.

Although this was only a short cook, the smoker came up to temperature very quickly, (the Stoker helps a lot with that), and, more importantly, held temperature with very little attention from me. Overall, the performance was excellent.

Second Cook - Pork Butt
We needed to cook up some pork for a few people and so this morning I clean out the smoker from last night's cook and re-fired it. We seasoned up four pork butts, each weighing in at about 7 lbs., and I put them into the cooker with two on the bottom grate and two on the top grate. I've done this before with the old cookers and they always had a hard time coming up to temperature and then holding temperature with that much meat in them. Not so today. I attribute that more to this cooker being new and all the seals being pretty tight while the old cookers had become pretty leaky. They've been running for a number of hours now and again the temperature is rock steady.

I'm liking the new cooker.
 
Nice write up, but where are the pics of your setup?

I missed you guys at the Jack, (except when you got the call) but was cooking with Smokin' Ty who also is an all WSM competitor and he has road cases he built for his bullets that are awesome, and uses a 5x8 enclosed trailer locally, just the few comps I cooked with my bullets I've got tweaked legs and bent waterpan clips-so I know what you mean about the beating they take, I now have 3 Rubbermade cans with handles so they fit nice and stable.

Couple questions for you VQ- You mentioned the larger waterpans on the new WSM, since you are using the Stoker, do you use water-or just foil the pan?

I didn't really pay too much attention to the 18.5" WSM on display at my local dealer and focused on the 22" WSM instead-the thing about the new thermometer and bezel, its the same as the ones on the newer Genesis and Summit gas grills-they look nice, but not worth the cost IMO. I ordered a couple for my coffee roaster and they are the same and not calibrateable, but I'm sure Tel-True will have a replacement soon enough if not already.

Can you share some pics of your 4 bullet Stoker setup?
 
Brian, this is a picture of how we typically set up our cookers for a competition.

The tables in the middle are two Lifetime personal tables that are adjustable in height. The Stoker is at the back/middle of one table and all the probe and fan wires run to it and out from under foot. I position the blowers on the cookers toward the back (opposite the doors in the picture above) so that I can easily see them and also to keep them from being kicked when people walk around them.

Regarding the water pan, I've used everything from water to sand to clay pot and combinations there of. Personally, I like the shallow water pan from the old style cookers which I can easily line with a single sheet of foil. I don't find that any particular material in the pan has a direct impact on the temperature control while using my Stoker. Based on the conversations I've had with people, I think what you use in the pan comes down to personal preference. Some folks swear that water makes a difference and others are just as adamant about using nothing more than an empty, foil lined pan. Whatever makes you happy is what works best!

We really do need to come up with a way of better protecting our cookers while in transit and I've kicked around a couple of ideas. One idea that I feel inclined to try out is to make a jig out of plywood that the four cookers will set down into. I think that I can cut a few rectangular holes in the plywood with a jig saw that will correspond to the shape of the bottom of the legs. That would lock the legs into place and I can then install D-rings on either of each cooker and then use a ratchet strap to anchor down the rest of the assembled cooker by running the strap through the handle on the lid. The I could use hinges to attach another sheet of plywood to the floor jig and then use some bracket hardware to keep the second sheet of plywood perpendicular to the first and protect the cookers from being banged into. This whole thing would have the cookers four in a row along one side of the trailer. I'm planning to invite Wile E. Coyote over to help me build it and then see if we can see it to the ACME company!
 
We did a run of what we call "production" spare ribs yesterday meaning that they get trimmed down to a St. Louis cut, smoked along with the trimmings, quick chilled and then vacuum sealed and frozen. We'll sometimes pull out a rack or two and reheat them for a quick dinner. Nothing fancy here which is why we call them our "production" ribs.

Anyway, I still have nothing but praise for the new WSM. Now that it has a few layers of barbeque gunk on the seams the only time I see smoke escaping from anywhere other than the top vent is when the Stoker has the fan engaged.

I mentioned it before but I need to reiterate how much more stable the cooker is with newly designed legs. The wider legs and small outward flare really make a difference, especially when the cooker is loaded down with meat, like the second cook I did with two 7 lb. pork butts on each cooking grate.

Has anyone else purchased one of the new 18.5" WSMs or has everyone gone for the 22.5" model? I think having one of the big units at home will be great but we're going to love having these four new small units out on the road this year.
 
I'm on the fence right now between a 22.5 and an 18.5 for home use. How many more people can I feed for the extra $100? I really need to make decision soon. I'm starving!

I have two 18" WSM's on the deck, one in the trailer and another still in the box. I'll mod them and all, but just never have gotten really attached to them, I'd drag them along with a couple drums to comps and use them it it struck my fancy, thats why I've been cooking on them alot lately using the Guru and trying higher temp cooks without it. They are great little cookers and the more I get closer to them, (and I never thought I'd say it) but I wish I had a 22" WSM! Only for the grate space.
 
Vince, Thanks for posting. Since we've gotten rid of the spicewine, we have decided to probably go the WSM route. I was going to ask you a few questions, but you adressed many here already. I decided to go with a 22 as the anchor of the pits, since space is not really a concern for us.

Maiden cook was yesterday (No pics, "too much beer mod".), and i have a lot of learning to do - I may still shoot you an email.
