    I am thinking of doing CC door hinges something like this

    I will have to tweak these a little before I'm done but you get the idea. Just something I wipped up. And I wasn't planning on using the long bar either, it's the only thing I had laying around. Didn't want to cut it

    Not completely sold on them yet though. What do you think?

    Got to working on the FB some the past couple days. I tacked some 1" nails to the outside of the inside layer to hold my insulation in place. I wish I could remember which thread I read that in to give them credit and say thank you. Worked great!

    Don't know if you can see but I tacked those on at an angle so I could "hook" it on on end and wrap all the way around to hook the other end. A word of caution this stuff is itchy and irritating to the eyes. Eye protection recommended!

    Now it was on to my outer sheathing. Seeing that it's 1/4" I left everything short by 1/8" on all edges for welding. This way I'll fill it with weld and grind a nice radius on it without worrying about grinding off all the weld

    All the square ones went on easy. Even the back with the radius of the tank on it. Just drew it on and cut off with the plasma.

    The top of the FB was a little trickier with the multiple radius. Not too bad, just made a cardboard template. Transferred it over and cut it out. Tweaked it with grinder. Worked pretty good

    Starting to come along now. Can't wait to get it done!

    Looks good......

    FWIW, to eliminate itch from fiberglass and other stuff....   rub exposed parts with cornstarch...

    Thanks Dave. I'll remember that. Regular fiberglass insulation never bothered me before. But this stuff a different story. My eyes itched

    I don't know which way to go on my smokestack. I was hoping to get an opinion or two. I just got done reading a bunch of old ones but didn't really answer my question.

    I have some 304ss tubing 6-3/8" ID. One advantage=it's free. According to the calculator I need 609.84 cu in. This is how it would work out
    6-3/8" = 19"H
    5" = 31"H
    4" = 48"H

    I've set it up there and aesthetically it looks good but mechanically is it too big? I think 19" would be too short. Can I use this 6-3/8" dia but leave it longer maybe 30ish?

    Now this is what Ribwizzard likes-
    This works out to be a 6" dia x 27" long (pretty close to what I'm thinking)

    Another possible idea is to use 5" inside of the 6-3/8" stainless one and leave an air gap (I really want to use the ss one and polish it up)

    One more thing I really couldn't find a definitive answer on. Is there any benefit to using a plenum over not? I have domed ends and it seems to me I could use that space just as well. Sorry about the quick sketch

    I hope you can see what I'm thinking on the sketch

    Lastly - sorry to rehash an old discussion but everyone seems to make some great and valid points. I'm not sure which way to go

    Thank you

    The plenum is primarily to allow for more room inside the CC.....  if needed....   like food racks or something ....

    That's what I was thinking Dave. With the domed ends I think I'll be ok without the plenum. It's unused space there really. Or do people typically put a small rack there? I wasn't planning on it

    How about that smokestack? If it is too big dia how would that effect it? I understand if it's too small but too big (within reason)? Would it cool too much before exiting affecting draft?

    Thanks Dave

    If your smoker is air tight, as it should / must be, an oversized exhaust stack is no problem....  If need be, a choke plate can be installed on top of the exhaust stack...

    What size pipe and length did you use for stack also what thickness

    I haven't done anything with it yet but I think I'm going to go with the 6-3/8" ID about 30ish" high. Gonna start there anyways

    Wow this job thing is getting in the way of my fun! Been swamped there lately but was able to work on the smoker a couple hrs anyways. Decided I wanted to finish my door completely and cross it off my list. I milled some notches in some 1/2 x 1/2 for the rails for the air intakes

    They did bow a little (kinda figured they would) when I milled that out and instead of trying to straighten I just clamped them straight and tacked in place.

    1st rail-

    Space it out with something laying around the right size and clamp. Tack it on

    2nd rail-

    And the finished (almost) product-

    I think I'm going to drill and tap some holes in the one end piece to make it removable. Probably won't ever need it but I'll be kicking myself if I ever need to take it out and I welded it in solid!

    Well off to the lower vent now!

    Keep up the quality work.  When done you'll have something worth handing down to your grandkids.

    Thanks tjmitche. I've got a 10 yr old son and the best part really is having him out there helping. I let him tack some stuff together. He's got a welding helmet also. He'll sit there next to me and watch. Hopefully I can pass something along so he'll be able to do something like this on his own someday if he chooses

  17. . Just seen your build, looks great. Just finished mine today! Surprisingly similar to yours. I worked on mine off and on for a year.

    Great looking smoker michigander2! Just wondering, how is it to move around? I was going to originally make mine a patio model like yours but it just keeps getting heavier and heavier! Debating whether to make it into a small trailer model so I can move it around with a 4-wheeler?
  19. I bought some heavy duty 8" solid wheels, two of them will swivel. I know I can push it outside and back in, but not sure about getting it onto trailer with ramp. I too thought about putting it on small Harbor Freight size trailer. I would guess mine weighs 500, yours heavier! Will watch your progress. Looks good!

    Thanks for the info. With that 1/2" FB mine will be closer to 1000 lbs! 99% of the time it will never leave the concrete just going inside the shed when done to keep it out of the weather. But there's always that 1 time...
