What is the mailbox mod?

Found some pics of my mailbox mod to my MES40. Same can be done with the MES40.

Aluminum box and tubing.

MB, earning it's keep, smoking fish

Since the OP has a tube, here's a pic that I've done with a couple of my tubes so I could use it in the mailbox. Made this steel rod tube holder that raises the tube up off the floor of the mailbox and prevents it from rolling around.

Also note that for such applications, I would not fill the tube full. Too much smoke. Instead, fill the tube half way, turn it horizontally and shake it left to right vigorously keep one of your hands covering the tube's main opening. Perfecto!!

Oops, just realized the OP has a square tube. No concerns about it rolling around but would still be nice to make a support stand that will raise it off the floor of the mailbox for air circulation. I would also hold from filling it up as I mentioned above.


Now, here's a link to a recent thread I did attaching a small mailbox to a MES30. I use a tray in this small mailbox. Don't know if a square tube would fit, especially if you add a support stand.

Cmayna, i like the idea of a stand for the tube. Ive wondered if I could fill it half way and not jam pack it full. I will do that for sure. I was tempted to leave the door cracked it put out so much smoke! I wanted Smokey cheese but gosh it was really smokey!
