My current Modified Smoker Combo
Here is how the modifications evolved over the years.
Six year old standard Traeger Lil Tex Pellet Smoker with heat and smoke provided by pellets which is consider by KCBS to be competition legal. Replaced the 3 position control with a digital control, added a second shelf, modified the auger, replace standard auger motor with high speed auger motor and added a chimney.
Added Smoke Daddy and A-Maz-Smokers
Smoke from Smoke Daddy. I have since moved the input below the drip pan.
Designed an Auber PID Control System, based on Billy Merrill concept, and built it using off the shelf products. Added an adjustment for fan airflow and auger speed.
Added Rock's Stoker with wifi setup to provide monitoring of up to four meats and pit temperature. Added an interface between the Auber Controller and the Rock's Stoker which provides me the capability to adjust pit temperature remotely through my home network or the internet. This also provides me the capability to program pit temperature changes based on time or food temperature. This is KCBS legal.
Attached a Master Built Smoke house to increase cooking area from 422 to 1139 square inches and to hang sausages. Heat and smoke travels from the Traeger through the MB and out of the MB upper exit vent. I left the propane installed to provide the additional capability to operate the propane side with or without the Traeger operational.
