The 4 gauges could be overkill however it gives you the cooking temps at the grate level on the hot end and the cool end so you can see how the heat is diffusing. With the multiple moveable plate setup it's easy to redirect some more heat where you need it. And the 16 ga plates are plenty...
Something doesn't sound right here... 1/4" to 1/2" steel? 1/2" would be like armor plating for a tank. Most smokers are somewhere around 10 gauge material. The internal baffles we are talking about, I don't see any reason to use very heavy gauge material. They are simply in place to diffuse...
This post (and question) was quite a while ago, but a good question about "why the variable damper". When I put all this together I thought it was going to be necessary to limit the heat going into the cook chamber so I made this plate on a hinge so that I could control that opening. But...
Sorry for the delay in responding. Hectic holidays. Regarding my baffle and diffuser plates... I'm not positive but I think the main baffle was 12ga, and the baffles were 14ga. I just bought these at Home Depot in the same area with the expanded metal I used to make the fuel storage box. It...
Hey VPB,
Yeah that was a little item I missed in my fan system, blowing the ashes up in the cook chamber. But since then I took a frying splatter screen that fits right in front of the opening and that seems to have solved the ash blowing problem. I still need to damper the fan though. This...
Yeah, here are a couple. I still need to make one more mod on the fan. The side with all the holes is the air inlet side, but it needs a damper to control the air intake. right now it just blows full on. Since I'm not using it with a digitial feedback contoller the volume of the fan isn't so...
The variable damper is just another way of controlling how much heat gets from the firebox into the smoke chamber. There seemed to be a lot of discussion about how much area to block off from the firebox to the cook chamber. There are some websites showing the flow calculations of the opening...
Finally got around to getting some pics posted.
Outside pic with 4 thermos to monitor heat at the grill plate and the top of the chamber, and front to back.
The wire basket bent from a single 24 x 24 sheet, bent corners, no welding...as described in this forum. (Thanks)
