OK guys! ... and Todd J ... I hope you can chime in on this one! I was totally jazzed to receive my Christmas presents of: an AMNPS and an aluminum mailbox!! Wow! So, I assembled all the necessary parts, modified my electric smoker (Todd J says it's similar to an MES analog) ... and set-er up to smoke a venison tenderloin and some ABTs! Well, seems like there are a few tweaks needed to get this working properly. First off, I drilled 3 holes (about 1/2") in the bottom of the smoker near the drip pan (as per Todd J's instructions). Then, I drilled 3 - 3/4" holes in the door of the mailbox and in the back of the MES knock-off. As you can see I connected the mailbox smoke chamber to the MES knock-off with 3" duct. The problem is that the smoke from the AMNPS doesn't draw out of the mailbox and up and into the the smoker. Actually it back-drafts a ton! ... even with the doorof the mailbox open, it doesn't pull the smoke into the smoker. Do I need more heat? (I saw some guys talking about that issue). Do I need more holes (actually I plugged the holes in the bottom of the mailbox 'cause the smoke was pouring out of those also. I'd prefer not to have to hook up a fan or air pump ... in my mind, I'm thinking it should draw fine. Any and all suggestions are welcome! (oh, and the tenderloin turned out great anyway ... as did the ABTs!! I simply put the AMNPS inside the smoker and let-er go!) Thanks! ... The Wisconsin White Rhino!
