24" x 84" Propane tank brain storm with build starting. Pics added

[Rodcrafter]

Just so you know I used the 1/2" on the door so I wouldn't have to put bracing on it. I used it on the bottom so that if it hit the road it wouldn't hurt anything but the road. The bottom of a FB is the coolest part. I used it on the throat side because it also has a damper on it so I can close it off and just use the FB for vertical cooking without having to heat the whole smoker.

I got the firebox all drawn to scale tonight and plate list all written up. Just have to get the tank cut open so I can get the measurements for the circular plate at the firebox end of the cc and the baffle plate dimensions. I'll have my buddy cut it all out on the CNC table.

It is nice to have buddies with cool tools

Got some initial measuring done and marking for the initial cut. Made a little home made tank roller which makes it a ton easier rolling the tank for measuring and cutting. I can't take credit I saw it on YouTube. The steel casters were $5 a piece and just screwed to some garden timbres I had at home.

The picture with the square is just a way to get a square cut on a round end tank without having to try and measure off the irregular weld bead. This maybe common knowledge but I hadn't seen it done this way and the best way I could come up with to do it. Basically you run the square off the end of the bell at its highest point and even the gap at the top of the tank by eye. Put a mark at a measurement. I used 10". Then measure from those points the additional distance you need. In my case this was 20" additional. This will give me a 30" warming chamber and 54" cook chamber.

Not ground breaking I'm sure for most just posting so if this thread comes up in a search it may help someone.

That's a cool idea. What about jigging up something to hold your torch too?

[p3ripperfw]

You could probably make that happen. I don't use a torch as much these days so I'm better with a cutoff wheel.

[Big T]

It's nice to be able to rotate it when you need to. I've thought about throwing one of those together but I like to do things the hard way evidently.

[p3ripperfw]

lol I hear ya bigt. It makes it worth more if it was as difficult as possible

[p3ripperfw]

On the calculators it is showing the half moon to be 13.25". I'm needing 69 sq/in. Has the calculator figured out at a throaty width of 13.25" with a 24" diameter cylinder that 69 sq/in is achieved?

[Pete Mazz]

My calc shows this:

I'm using a square firebox now tho. Is there a function on that one for a square box that would show it like that?

[p3ripperfw]

Never mind Pete I just saw the link to your stuff. I'll give it a shot and see how it looks. Thanks

[Rodcrafter]

Pete has a calculator for just about anything

Got the tank cut today and lived to tell about it. Larger section is the cook chamber smaller is the warming chamber that will sit on top the fire box. 4 1/2" angle grinder with a cut off wheel was super efficient cutting the tank. Only took 2 wheels. I also cut off the feet and other original pieces. I plan on using the feet for door stops.

Off to a great start!

You've got the ball rolling now !

[ajfoxy]

Looking good. Build coming along nicely.

I do like the roller. A bit of jigging and one could have the plasma torch in place and cutting whilst you turned the cylinder.

Nice use of technology.

Thanks guys. One question on the baffle plate. Is it sloping downward toward the baffle gap? As in the firebox end would be slightly higher than the end opposite the firebox? This makes sense to me but want to make sure that is the case so I can measure the baffle plate dimension.

[BitBucket]

I'm far from the level of build experience some of these guys have, but I've always considered the baffle plate as something to be set level with the rest of the CC. I can use a jack screw to raise and lower the end opposite the FB if I want to slow or speed up the movement of the heat/smoke that way without having a baffle plate incline to overcome. Do you NEED that? Probably not, but I like options!

[Rodcrafter]

Yeah what BB said


Making memories!

[p3ripperfw]

Ok sounds good I'll make it level. I think I remember that sloping baffle from an article frank had done years ago.

Awesome work.
