So I got the fire basket in the mail yesterday and my first impression is it is a lot smaller than I thought. I plan to do some ribs on Sunday but I did have some time to play with it a bit. First thing I did was remove the ash sweeper which wasnt hard at all, just wiggled the handle loose and it all came apart. The base of the fire basket is not big enough to cover all three air inlets so I used aluminum tape to seal up two of them and placed the fire basket over the third hole.



Next I made a really crude valve out of tin foil(imagine a T-ball stand), here is the valve shut:



Here is the valve open:



Here is the fire basket installed with the top grill on:



Ill report back after Sunday with my thoughts on the wGrill as well.

So I used the fire basket and the wGrill yesterday and here are my thoughts.

1. The base diameter on the fire basket should be increased to cover all three air inlets.

2. You should probably use a grill for the bottom piece instead of a solid metal sheet with holes drilled in it, the holes got clogged very easily.

3. You should put some kind of heat proof handle on it so its easy to pick up and adjust or clean when its still hot.

So here is how the cook went. I started the day by filling up the charcoal basket and using the blow torch to get 5-6 piece of charcoal lit. The temp got to 200F with the valve in the open position and it just stalled there for the first two hours, I attribute this to the ashes clogging the air holes in the basket. By the third hour the temp had dropped to 180F and I decided to go in and have a look. I removed the meat grill and lifted the lid on the fire basket, sure enough all holes were clogged with ashes. I went and got some oven mitts and picked up the fire basket and poured the contents into my charcoal chimney. The fire basket was extremely hot and the oven mitts only helped a little, having a heat proof handle on the basket would have been great here. Once the basket was emptied and the clogs cleared I put it back over the air inlet, poured back the already lit charcoal I had in my chimney and then placed fresh charcoal over the top to fill it up, replaced the meat grill and closed the lid. I also removed the tin foil valve at this point as it was blocking too much and not allowing air to flow in. With one air inlet completely open the kettle hovered around 250F naturally, I continued the cook for another 3 hours and the ribs were done. The fire basket was much more efficient when the lit coals are on the bottom of the basket instead of the top of it. The tiny holes might have been ok had I used my Dog controller since it would 'force' air through, the only issue I see with this is that hot drippings would go down into the fan since the air inlet is also acts as a drainage point. At this point the fire basket I would say has potential but will need a few revisions before I could recommend it as a solid product.

The wGrill I had issues with, I could not connect to it with an iPhone, Samsung Galaxy S4 or my Acer laptop. I could see wGrill from my laptop but every time i tried to connect it said failed to connect, I made sure to check off "display characters" to ensure I was using the right password= 1234567890123. I could not see the wGrill from the two smartphones that I had available to me during my cook, it simply would not show up even when I refresh the search. Also the inlet for input 1 broke off and fell inside of the unit, I was only able to use input 2 because of this. I used the unit manually by checking the display every half hour.

1.Indeed I made 2 sizes, you got the smaller one. But I am not sure the bigger one is good or not. I need an exact size of basket

2.This is the very first trial. I drill small holes on botton in purpose. You can drill the holes bigger, say 10 mm to 15 mm.

3. Power Draft will work good with basket. To prevent hot ash falling to fan, you can use my fan+corrugated pipe system

4.I may need to add a handle on basket.

5.wGrill can talk directly to a smart phone, or a computer. I have tested a few pieces myself.
There may be bug on Adhoc or Infra. which must be solved in next version

Ill make you a drawing with measurements for an improved design for the basket when I get some time to put some effort into it. I will try enlarging the holes myself to improve air flow as well. I think once you work out all the little issues this fire basket will be a really good product.

After reading the trial, IMO I would put the "V" in the bottom of the firebox where the vent flanges are. If you want to sell to most Weber users, they will not want to disassemble anything to use it. I am not sure how your wGrill attaches to the firebox, but I think making this easy to install will be one of the biggest selling points.

I expressed concerns about the resistance to taking the blades out to Wang earlier in the thread, I think the final version will find some way for it to work with the blades in.

The wGrill has nothing to do with the fire basket, Wang just happened to send both things to me at the same time which is why I lumped them together.

Thanks all.
V cut buttom will work, but will increase manufacturing cost.
I am thinking to make full Kettle with my basket and power draft.
It will be a big project because that most people do not trust my design.
Indeed my UDS or PBC design with ash box and fire basket works great.
I am using it a couple of times for my self.
But none shows interest in my UDS or fire basket.
UDS is so popular, I guess that most do not think there is any free room to play with.
My big puzzle must be name of "made in China"

If you are able to work the kinks out I think you may be onto something.. I know a few that would be interested in turning a kettle into a smoker with the ability to utilize the entire 22" grate.

Just give me the size of diameter and height of firebox.
I will use grate on bottom than drill holes.
I am sure you can easily upgrade a kettle.

So I had some time today and got the measurements for you. I used a piece of cardboard to make a template then measured it:



So this is my design:

Its basically the same design except larger to cover all the inlets and also three triangle shape cutouts so the basket will "ride" the three blades, this will allow the blades to act a valve. I suggest using a grill instead of a sheet for the bottom but if you must use a sheet then use large holes. For the lid, I have decided I want to use a inexpensive clay saucer that will just sit on top of the basket.

Normal view without clay saucer lid:

I was thinking the top should probably be inverted so theres more airflow:

Indeed I was thinking water pan. But worrying that it will collect grease and may be cause grease fire

Maybe ill put the clay saucer on upside down so it doesnt collect any drippings that can cause a grease fire. I figure this will also bring down cost since a lid would not be necessary from your end, purchasing one locally would be more cost effective and they are readily available.
