1. a metal box with a drip tray.....a shelf for one of those Tea Tree Lights...[40 diameter aluminium dish x 15 high with a candle wick]
2. a wire rack above the tea tree light to support an unwound [50 diameter] stainless steel scourer pad
3. a 40 diameter computer 12 volt pillow fan mounted in a tube pointing the air onto the scourer
4. a small low pressure 12 volt
peristaltic pump ..... do not be tempted to use a 12 volt
windscreen washer pump]
5. a reservoir of sump oil [diesel engine oil is preferable]
6. a metal chimney from the smoke generator to the vessels exhausts
The build of the smoker body itself is not complicated ....brass sheet sides/tops & plates M2 screwed together with 10x10 brass angle iron corners ....
The use of 20 diameter copper bends/unions & tube aids the simplicity of manufacture of the unit....40 to 20 concentric reduce is also handy for the fan tubing
The sizing for the body is say 50 to 70 mm cubic...then with the fan tube bolted & entering on a side & the exhaust exiting from the top etc
Light the tea tree light, with your R/C gear pulse the peristaltic pump until a few spurts of sump oil smoulder on the S/S scourer
It would also be advantageous to use R/C & speed reducer to control the voltage/speed to the fan
Quite a bit of trial & error in the commissioning & setup, however the above does work, each tea tree light is about
10 cents and will last for approx. 15 minutes.......diesel sump oil is inexpensive
Ideally, you would need use two [2] functions on your R/C Tx....one variable & one a pulse only
Make the smoke generator totally modular...you will need to lift it out of the vessel before storage/display in your home as the smoke generator will stink
