Stumps Clone Pellet Adapter

Post by pr0wlunwoof » June 8th, 2018, 7:16 am

So. I got bored this week and decided to find a way to build a pellet smoker. My dad has one and my boss got one before I finished my stump clone. I do believe I have a superior machine in every way imaginable, but curiosity doth drive innovation. In my searching I found a post where someone used a stainless steel tube to run charcoal and pellets at the same time, but I would like to run pure pellets. So far this is what I have found:

http://www.allchinas.com/burner/

This design is based off of the gravity feed system of the stumps but with a small cup in the bottom to hold the fired pellets. I was thinking I could make an insert that sits above the grate that would be a funnel with the cup at the bottom to hold the burned pellets.

Interesting. If I understand what you are wanting to do, you want to use the chute as a pellet hopper and burn pellets as a gravity feed. is this correct? :-B

When I made the stainless tube and used it to add pellets to the charcoal in my GF the issue I found is the pellets that are above the pellets being consumed or used as fuel if you will don't stand up to the heat and humidity, they swell up. I'm no pellet grill expert but it's my understanding that most if not all pellet burning grills store the pellets in a hopper and utilize an auger to move them into the burn pot which eliminates the pellets exposure to the by products of combustion.

Yeah. Based on what I have read about some pellet stove and that guys design I think it should work pretty good.

Yeah I read your entire thread. I get that the issue was the swelling of the pellets, but I think you suffered the same issues that the original gravity feeds did which is what I understand as "bridging". By staying with the concave design of the new firebox I should be able to avoid that. At least in theory Image

This stove works off gravity without an auger.Image

I was just thinking about putting a pellet pro hopper coming through the other side and having the pellet pot under the transfer tube. But I’m not sure exactly how the pellet hopper works and if it would get hot enough for the size of the mini GF Cook chamber.

The pellet pro would work. It generates plenty of BTUs and with the mini being insulated you should be able to run it much more efficiently than most pellet grills.

Actually Frank had a small insulated cabinet at a gathering a few years ago with a pellet pooper and he said it is almost too well insulated to keep the pot hot. I would talk to him before buying the unit
