irnworker433 · Post by **irnworker433** » September 12th, 2016, 4:44 pm

So here is my 1st attempt to build a smoker... far from perfect, but I think this dawg'll hunt.

Luckily for me we have a really nice overhead crane

and some great drawings compliments of yous guys. A plasma cutter, and half a braincell left. Ive yet to cut the doors on the boxes, handles, shelves, stack etc etc etc

Still need to do a lot, one day at a time...More pics to follow.

Peace

That is one big cooker you are building there.

Nice build so far. And it must be really nice having all that space around when building... I am envious of the space and equipment...

That's one huge door no doubt you need a crane. Looks like you're on the right track. Keep up the good work

Ok, so we had a lil change of plans today. Fabbed up the CC rack assemblies. Went smooth, made sure the racks were as square as possible. Golly gee is that expanded stuff razor sharp. Seems awful dangerous if your not careful. Be leaving DNA quick like. Anyhow, Just need to weld out the rack uprights and the inside of the cook chamber is DONE. Adding gasket mtl on cc door also manana. Progress!

Peace

So I have a question. As per drawings I have my exhaust stack cut flush to top of CC. Someone suggested to have it midish way down the chamber to retain heat and smoke.....Whats the professional concensus?

Post by **Pete Mazz** » September 16th, 2016, 4:46 am

I don't think there is one. Most have been built flush but there is a growing group of builders that extend them down. You can always experiment with adding a piece to the inside of the stack and take temp readings before and after.

I would say if you do some testing with it maybe use a rolled up piece of thin sheet metal in the sack so you can adjust it by sliding it up and down. But to me the most important part of the test is how does it effect the smoke content in the meat. So using the biscuit test you may be able to see the difference on the biscuits when done at the different levels. I personally would say this is more important than just the even temps.

Oh and can you show us the build of your racks? I'm thinking racks that long must need 4 square tube rails long wise to keep from bending under the weight. What did you do?

irnworker433 · Post by **irnworker433** » September 16th, 2016, 7:47 am

Rodcrafter, good point. Those are some lengthy racks. Ill add additional tubes lengthwise to help hold the load. It did flex a lil more than I liked. Maybe even crown the middle ones slightly upward.
I /we have a whole bunch of things to learn about operating this thing.. Or else its going to end up a 4000 lb counterweight for one of our ski lifts.
I am thinking her name will be Betsy...Shes a really nice gal who can cook like a mofo...But shes a HEAVY smoker...

Peace

Ill look into the biscuit test for sure.. Thanks for the tip.

I was thinking, I know this could be a mistake.... lol
I think a good alternative for the additional tubes would be use 2 on the front and back side with a bunch of 2 inch vertical pieces separating them to create a bridge. This would serve as a handle and be stronger than tubes laying flat.

Do you get what I'm saying?

It would be great to use as handles for lift whole hogs too.

Kinda like lil trusses spanning the bottom of racks?

Post by **Rodcrafter** » September 17th, 2016, 9:58 am

Yes, but I'd put the flush with the bottom and just add it to front and back so it would look like a lawn trailer sorta.

Howdy guys...Made some progress the last couple days.. Stiffened up racks w 1" squaretube, I can stand on them now... I'm 245lbs.... Sealed CC Did a smoke test with the machine we have...No leakey......Made counterweight assy n welded out. Prolly has 125 lbs of scrap in it....Stays open, and moves effortlessly. Stole some hood latches from an old Army truck we have out in the weeds on the CC door (shhhh don't tell my boss

) It will never go fast enuf to lift the hood again anyways......Works good keeps it nice and snug....NOW we can move on the the boxes...I think...

Peace

Great build....looks like your meat order will need to be placed soon.

Just a note on the larches. First, I never thought of using them but great idea. Second, if anyone is interested, they are readily available from any off road/jeep parts store/mail order. Ask for hood catches for a 55-95 cy/yj jeep. Black will run you about $25 and stainless is available in stainless as well.
