I'm really wanting to get something set up so I can use my AMNPS with the UDS all the time. I have a large rural mailbox at my disposal but to me that seems to be way to large and funny looking. I don't really have the ability to make anything from scratch so I'm searching for ideas. So far I have come up with a couple that I wanted to get some opinions on. My first thought was an old metal lunch box. Seems like it would be the perfect size but I can't seem to figure out how to get around the lid being on top. Wouldn't the "exhaust" or the smoke pipe need to come out the top for the best flow or could it vent out the back? Option 2 is a vertical mailbox such as this.. This I would lay on it back and vent the smoke out the top with an elbo into the UDS. Of course if anyone else has any other clever Ideas I'm all ears. I have a 40lb bag of pellets I'm itching to use so I am wanting to get this done as soon as I can. Thanks!
