Went all in on the mailbox mod.

Decided I wanted to try some cold smoking and ran across the mailbox mod post from 2007 or so. I had the Great Outdoors Smoky Mountain smoker setting on a piece of waferboard on top of a couple cinder blocks which all set on a Harbor Freight furniture mover with wheels. I took the furniture mover apart keeping the wheels and board the wheels attached to then started to build from there. Top deck where the smoker will set is 16" off the ground so I don't have to bend over so far to reach the bottom of the smoker and I can see down the racks without bending over as much. Still need to cut holes in the smoker and mailbox as well as mount the mailbox to its shelf. I added the lower shelf so I have a place to put my racks when I'm not using them.


I'll post up a completed pic in the next couple days.

Looking forward to seeing the final setup!

Looks great so far!

It should be ok, but I would want to run a hunk of thin aluminum the wood and where the mailbox sits.  Just a little bit more "thermal protection."  

Be sure to seal that wood before outdoor use.

I was thinking about adding a little aluminum flashing to the wood for grease protection more than anything, I still have to block the mailbox up off the deck so the door will open right which should give me a couple inches of air space under the box.

I'm sure its going out under the car port just like it is considering the last piece of wafer board I used to set the smoker on was still good to go after 10 plus years. I'm not one to have the patience to wait for paint to dry, it might get painted or sealed in the spring when the weather is conducive to doing it out side but right now its 20 degrees and snowing.

Great job on the MM, you will love the way it works.


You might need to drill an air hole or 2 in the box door, if your AMAZN goes out that might be the problem.

Have fun!

Looks great. Are those elbows galvanized?

Ya most likely. If I ever get the smoker hot enough to matter I will worry about it then.
Yeah, for cold smoking it won't be a problem. I have the identical smoker, converted to NG. I have a mailbox mod now with the mailbox attached directly to the smoker but want to add some ducting to let the smoke cool before entering the box. I'm only using it for cold smoking at the moment, but may want to hot smoke in it again some day, so trying to find something that isn't galvanized.

I have a smokey mountain smoker as well. I do not have a bottom vent anywhere and I think this is why I do not get a lot of smoke. I even have the A-maze tube. So I'm thinking about adding a vent to allow air flow and connect the mailbox when needed. Did you have to cut the hole yourself? Also, when the mailbox is not connect what do you cover the hole on the smoker with?

 Thank you

I have the same smoker as well. What did you do to convert it to NG? I would like to do that myself as well a make one of these mailbox cold smokers.
Cheers

This is the pipe I purchased, looks to be aluminum. 

https://www.lowes.com/pd/Lambro-3-in-x-96-in-Aluminum-Semi-Rigid-Flexible-Duct/3240915

Near as I can tell these are the elbows I got and they appear to be galvanized steel.

Might have to go to Home Depot and check these elbows out as they say there aluminum.

Thanks MD, I already have the flex hose. The elbows at HD look promising, thanks for the link

Dee, it's been several years and I didn't document it very well. I know I used this hose : amazon" style="max-width:120px">
I don't recall if I had to use any pipe adapters - I seem to recall needing one. I'll check the unit when I get home later. I did have to drill out the orfice. I did use the existing gas flow valve.

My local 2 Home Depot stores don't carry the aluminum elbows so I ended up ordering them off Amazon to replace the galvanized one just because.

I ended up cutting a 1/2 inch wide horizontal slot where the address goes on the front of the mail box for air vents. 2 Harbor freight rectangular magnets cover the slot to control airflow. I also taped up the holes in the bottom of the mail box with aluminum tape so I can control the airflow better and maybe keep my pellets from flaming up.

Found some galvanized sheet metal in my pile of stuff that I used to cover the deck and sides of my smoker stand, ran out so the front of the stand is still wood but I have a little thermal protection on the wood. I'll have to get some new pics in the daylight.

Is it important to get all aluminum components including an aluminum mailbox?

Somewhere North of 400 degrees galvanized metal starts to give off toxic fumes, even though we don't smoke let alone cold smoke at that temp its probably best just to stay away from galvanized piping. I sometimes run my smoker up over 400 if I haven't used it in a while to burn out the spider webs and what not so I figured I should at least have the elbow coming into the smoker not be galvanized. Steal sheet metal would work fine once the protective oils are burned off but unprotected steel is going to rust.

My mailbox is a painted steel https://www.lowes.com/pd/PostMaster-7-in-x-9-in-Metal-Gray-Post-Mount-Mailbox/3033317, I didn't find any old style aluminum mailboxes. At the temps the pellets burn at there doesn't seem to be a problem with the paint on this mail box. Twice my pellets started to flame and while I now have brown spots from the heat on my mail box the paint is still intact.

Good looking MB on your GOSM. I use the tube smokers in my GOSM. Both directly in the pit and in the mailbox. The tubes will work in the pit as long as the pit temp is below 285°f. Above that the pellets will ignite and burn instead of smoldering. This time of year I can put the tube right in the pit for cold smoking as it only raises the ambient temp 10°f-15°f in the pit. Which I actually need because its been in anywhere from -8°f to 30°f here. Without the heat I'd be smoking in a freezer! During the summer months I use the mailbox for cold smoking.
