    63.3 Gallon RF, nearly complete

    TAllow me to start off by reminding you that I don't often do things the easy way. I wanted to have a rain cap on the top of the chimney and couldn't think of a simple valve I could fabricate that would remain inside the exhaust stack. So I made the exhaust cap on the inside of the cook chamber...

    63.3 Gallon RF, nearly complete

    Before getting to this step, I had spent most of my time trying to figure out if I was going to go the easy route and weld in a single piece of plate for the reverse flow baffle, or if I was going to make mine funnel towards a drain. Of course, I never like to do things the simple way, so I...

    63.3 Gallon RF, nearly complete

    I have previously mentioned that I saw there was an issue with the distance of the bottom of the CC door to the top of the firebox. This image shows that there was nearly 7" in between the top of the firebox to the bottom of the door. I decided to take the flanges off the side of the door and...

    63.3 Gallon RF, nearly complete

    Yes, Ray! The grate is removable. I had tried to figure out how and where to put the drawer for placement. I kept getting stuck on the design of it. I can only mount a drawer in the back of the FB, opposite the door. (Dimensional constraints overlapping the door and outer edges). I also couldn't...

    63.3 Gallon RF, nearly complete

    I then decided to weld the FB to the CC. In hindsight, I'm probably doing things a little backwards. At this point in the build, I was probably two months in and wanted to see some light at the end of the tunnel. So I focused on joining the FB and the CC. It's steps like this that took a lot of...

    63.3 Gallon RF, nearly complete

    Hopefully you guys appreciate the detail in trying to provide. I don't have a good camera and didn't do a video blog of the process. If I'm missing something or you have a question, feel free to ask! Similarly with the CC hinges, the firebox hinges were templated on bristol board and...

    63.3 Gallon RF, nearly complete

    By the way, I'll post as often as I can, but there's about 100 pictures and almost a year's worth of work. So it'll take a little while to upload it all. The upper compressor mounting bracket and the legs were left on so I could trace out the dimensions of the door and square it up to the...

    63.3 Gallon RF, nearly complete

    Thanks! And as promised; here is the beginning of the transformation. As I said, I took about 9"of the body of the tank to bring my volume down. I eventually did this with oxy-acetylene torches with plenty of practise on scrap pieces to twice slag build-up on the cut. It want perfectly square...

    63.3 Gallon RF, nearly complete

    I'm back again. My last post here was on September 19 of last year and I was getting some technical input from you guys on my build. It has been nearly a year, but it's now about 90% done, the rest of which is purely cosmetic. My project started life as an 80 gallon vertical air tank and was...

    Proofing ESV Calculations for the 63.3 Gallon Tank.

    Thanks Dave! 4" would look more proportionate too. I can do that. Is 36" above the CC an ideal length or optimum flow? If the pipe were shortened by 6" or even 12" would it reduce the ability for an adequate draw?

    Proofing ESV Calculations for the 63.3 Gallon Tank.

    Hey everyone, Much has changed since I last posted. I've been busy working away on the smoker, using your tips, calculations and ideas. I'm getting closer towards the end now. Just last weekend I installed the reverse flow baffle plate with a sloped drain away from the F.B. So far, this is...

    Firebox Questions

    Ok. This is what I originally kept getting in my calculations. It looks a little odd with the top of the FB and baffle mounted about 6" below my cooking rack. Thanks for the clarification, Dave!

    Firebox Questions

    They are about 6.5" from the center of the weld to the outermost part of the cap. Thats what you were asking for, right? Also, the center cylinder section is 23.5".

    Firebox Questions

    So I was about to order my firebox materials today and figured I'd check the fitment of my materials. I was originally going to go with a 18.54" wide, but this meant there would be a gap of about 6 3/4" from the bottom of the door to the top of the RF baffle. Design-wise, that didn't sit well...

    63.3 Gallon Tank Calculations

    I was thinking of the door facing the same direction as the door of the CC. I planned to put the intake vents beneath my fuel rack and cross-flow vents directly across from FB to CC opening. Both on the same side, and from what I've read thus far, in-line with the flow of air. This may be a...

    63.3 Gallon Tank Calculations

    So I started with an 80 gallon air tank, but the original length of 45.5" was a little too long. I cut a section out and re welded the cap back on to reduce the length down to 36". This gives it an original displacement of 18480cid and 80 gallons, reduced to 14622cid and 63.3 gallons. 1) Using...

    Those pictures are good. With the description, I can picture how it's supposed to work. I like the removable ash catcher design too.

    Thanks for the input! I'm a ways away from starting my FB, but I can work on the design and dimensions in the meantime using your input.

    Firebox Questions

    I'm beginning the planning for my build. I plan to use an 80 gallon air tank for the CC. I was just wondering if I could get some ideas for the firebox. I read through the calculator that daveomak posted. Because my build will be an RF style, I was using the calculations he provided. I have...
