    I started work on my smoker.  Mostly prep work and cutting; in this case, prep work includes "getting 4300 lb of steel off the trailer."  (Not all of it will be used for this smoker; I'm figuring roughly 1500 lb when I'm done.)

    First step: get steel.  3/8" plate:


    Lots of 3/8" plate:



    Note the top plate--it's 8' wide, wide enough that I found I'd need to cut it down before I could move it off of the trailer.  So cut I did...briefly:


    Hrm.  Why did my cut suddenly go to crap, and where'd all that soot come from?  Oh, that's why:


    Guess I'll make a quick unscheduled trip up to


    Back to work.  I took about 3' off of that panel:


    Still, they're awfully big and heavy.  Fortunately, I have a solution:


    That's about half-a-ton of plate right there.  First time I've really used the bucket hooks; I'm glad my welds held.


    As seen from the driver's seat.  Right now, I'm bulletproof on the south side.


    Ahh, all unloaded.  Time for a


    More next week when I start on the firebox; I need to get about 25' of 1" square tubing to frame out my firebox, as detailed at http://www.smokingmeatforums.com/t/126978/firebox-design-review-and-critique.

    Nice choice in Beer.   Tried the "summer shandy"?
     
  4. Look's like you got yourself a project.

    Keep the picture coming.

    I'll be off work in another month and I'll be ready to start my project.

    How are things progressing?

    Stalled.  I started working on the firebox frame, but finals are coming up soon, and I also have a paper to finish.

    Hey OkieDave,

    Hope finals went well. I knew you said you were about to start back up on this thing and was going to see if you had? Subscribed and ready to watch. I have just started on mine as you already know but I have had some slow days with that tornado that came through and hit our neighbors to the north.

    I got sidetracked by life, and haven't done anything more.  I was just about to start back up this week, but the weather kept me from it; the past couple days have been nice, but I've been helping with the cleanup following the tornado.

    Bad, bad stuff up there.  I watched it go by from two miles away.

    I did finally finish my welding table, so I won't have to lay on the concrete to work.  That alone will be a big improvement, and I'll be able to move inside and go to gas (GMAW/MIG) welding instead of flux-core, so I won't burn through the tubing walls like I was with FC.

    There's nothing like a little public shame to get things moving again. When last we left, I had built one side of the firebox frame. I was using .035 flux core wire, and blowing holes in the square tubing I was using for the frame; I just couldn't turn it down low enough.  I had also been working on the ground, which was decidedly suboptimal.  I (finally!) finished my welding table this afternoon, so I took a stab at the firebox frame again.  The square on the right is the old one; the one on the left is today's work:


    Let's have a closer look at those welds, shall we?



    In comparison:



    Yes, I know; calling the FCAW welds bird-poop is an insult to birds everywhere.  I'm pretty happy with the gas-shielded welds, though.

    Now, the downside: the gas-shielded frame is about half-an-inch out of flat across its 20" run.  I tried to support the low corners and step on the high corners, but even with my not-insubstantial weight, it didn't budge (a nicer way of looking at that is that even with my fat self stomping the daylights out of it, my welds held just fine!).  I haven't decided what I'm going to do about it.  When I tie the two squares together (building a cube), I may just tack it up as close as I can, then use a BFH and some heavy clamps to forcibly tie the high corners to the remaining frame, weld it in place, and call it good.

    Thoughts?
     
  12. Yep, I cheated on mine and welded the pieces of tubing to the plate and then each side together, including the tubing.  My plate was squarer than I could ever get tubing to stick to being square.  Clamps and welds.

    Back in action!

    When last we left, I had managed to tack up a couple of squares to be used as the firebox frame.  Since then, I've accomplished this:


    It's been a long five years, but I finally escaped from law school.  The bar exam is over, so last night, I went out and did a little metalworking.  First up: cutting end plates for the cook chamber:


    Second: burn out the pipe segment (55" x 24" x 3/8") I'm going to use for the cook chamber.  It looks to be a section of gas pipe, given that it's coated in that horrible green epoxy.  No matter; fire cures everything!



    You can see the epoxy paint begin to pull and distort in the heat.  Next, it starts to smoke:


    ...then suddenly catches fire, falling off in big flaming sheets:


    More pictures this evening, when the light is better.

    Well...almost.  I graduated, but I missed the bar by four points (260 scaled score, with 264 being passing).  I'll be savoring that experience again come February.

    <sigh>

    I appreciate the thought, though.

    Post-Christmas update:

    Following a successful burnout, I finally found a set of hinges I like for the CC door at Northern Tool, and got them ordered:


    Next, I marked off the cut line for the top of the CC door (just the top cut; I'll cut the other three after the hinges are welded on).  A spirit level and soapstone gave me a nice line:


    A couple of hours with a grinder and a 1mm cutoff wheel (okay, five 1mm cutoff wheels), and we have a reasonably clean, straight cut:



    No pictures, because it didn't go well, but I also tried drilling holes in the hinges so that I could plug-weld them.  I'm going to have to pierce them with the cutting torch instead.  More on that later, after the new wheels for the cart come in.  There was an...incident...with a compressor and a cheap Chicom tire.

    Was that gas pipe 3/8 wall. And you said it burn off pretty easy. Light sanding and good enough to paint?
