I thought that Aussie BBQ Forum may be interested in a Cabinet smoker im building at the moment.
the END goal is to build them in australia but at the moment im in the prototyping phase where a mate and i are making them as simple to build as possible.
For those interested these smokers are refered to "gravity fed smoker" or "stumps clone"
while i dont like the bbq i have designed being labeled a "stumps clone" i suppose there is no getting away from it.
The design considerations were as follows
- minimal labour (plan on braising the corners after tacking them in place to spee dup production)
- perform perfectly WITH or WITHOUT a draft fan controller
- Can take Lump charcoal as well as Heatbeads
- Revision 2 will have a smoke management lever
- "managable" weight (under 300kg)
- Gastronom standards (2x 1/1 gastronom pans side by side)
- Slam latch for easy opening/closing
- well sealed
- fully insulated
Here are a few of the cad/actual unit shots
Some cutting diagrams we send off to the laser cutters

The first cad output of the smoker (early stages) to show the height

door and some of the walls removed to show internal structure
Those are 1/1 gastronom pans inside so LOTS of room
Each pan holds about a 8kg brisket for an idea

The expanded steel racks are done a little different to your traditional bbq, we are having them made out of 15mm/5mm bent steel instead of box steel to cut down labour

Here you see the handle for moving around, the laser cut holders for the handle that also hold the latch for the slam latch handle.
we were lucky enough to find the cad drawing of the handles so not much work needed to be done there to work out the dimensions

you can see here some more detail of the heat delivery tube coming out of the firebox.
we have not finished the drawing of the fire management plate but hope to complete that soon

yup......my mate decided to sully the pictures. with the door its a PITA to create it out of box steel so instead angle iron is used and the plate steel is welded to the inside, it makes for a much faster manufacturing process as well as a nice flush door as opposed to box steel were the door is set out of the pit.

machining a part on the slam latch because i bought the wrong height latch.....wont need to do this in the second revision

a few pictures of our progress, the pit is built quite fast and easily made square. the front steel is 6mm plate which is used as the main structure as opposed to box for quick assembly

Cover on chimney
Drainage hole and drip tray holder
Latch on firebox door
Prep/paint
She just got home. Im painting her now


Seals, clean, season and burnin left


for those whom werent following my instagram or facebook over the comp this happened
Reason
1. firebox leak was still present and i was unable to snuff the charcoal even after 24 hours
2. trailer at 100km forced air through firebox and re-ignighted embers
3. 50kg of heatbeads in the cooking chamber and 20kg in the chute ignighted
the CFA were fantastic and we understood that despite having 5L of water and 2x fire extinguishers it was not sufficient to put out the fire but only contain it.
Nothing was damaged
