I'm cheap. I kept reading about others using this wire rack or this sausage hanger they found on Amazon to hold their pellet tray, but spending that much money on something that simple just didn't sit right, so I headed to Walmart to see what I could find. Here is what I came up with.
The pan with the holes in it I found in the BBQ supply section. It is almost exactly the same size as the 5/8 pellet tray. It cost $2.30
Next to that is a package of three foil mini loaf pans. They were $.88 for the three.
The tube of silicon I already had.
Now it's just a matter of gluing it together. Turn all the pans upside down and put a couple of dabs of silicone on the outer edge of the loaf pan. Line up the outer edges of the tray and the loaf pan and stick together. Repeat for the other side.
Put the tray on the bottom of the smoker with the AMNPS sitting on top. I have found that I get a little more smoke with it up against the heater as the smoke is caught in the heat current and swirls around the smoker better. When it is in the far left position, as shown in this position, more smoke just goes up the back wall and straight out the exhaust. I use both positions depending on the pellets I'm using and how much smoke I want in the chamber. I usually start on the right side and move to the left if I"m getting too much smoke.
I actually made this some time ago, and just procrastinated about posting it. My try has been through LOTS of smokes and still works great.
