I finished up my first couple UDS builds this week. One for my dad for Christmas and one for myself. I added an AMNPS Ammo box mod to mine, which I'm still fine tuning. I need to work on my pellet lighting skills and probably add more airflow to keep it lit. Both have: 3 - 3/4 inch nipples/caps 1 - 3/4 ball valve Adjustable racks Once I figure the AMNPS out and we get some temps above freezing, I hope to smoke some cheese. Tomorrow will be Ribs. It sure will be nice to get through a cook without using 20+ lbs of charcoal. My OK Joes gets thirsty for fuel. Seasoning my dads: My build: Lit AMNPS Adjustable rack, pardon the oil that pooled during seasoning. Now for my BBQ Guru question. I have a DigiQ II set up with 25 CFM fan, will I be able to use that on the UDS, or will the 25cfm fan be to much even if I closed off the inlet some?
