Hey everyone! I just wanted to start this build thread, because this week a buddy of mine and I will begin building a competition BBQ pit trailer as our Ag Mechanics project.. Im going to try and keep up with it as we go, and i hope to be uploading pictures every week with updates if I can, as well as pricing! Let me know if yall have any questions! Here is where we've started so far: these are the preliminary designs, and the photos of the trailer we're modeling it after.
Plans are to build basically the same thing, except:
*making pits 2 feet longer
*adding fire wood storage next to fire box
*double axle instead of single
*adding a larger workspace in front of the pits, that will actually be hinged and allowed to swing out from in front of the pits.
Started cutting for the frame today.. Using 4" C Channel. The frame is 14' long, and 66" wide. The plan is that the pits themselves will come out to or just passed the edge of the frame, and then the counters will attach to them, and with the counters being 16" wide on each side, this should bring us to 100-102", just about the maximum width for a trailer..
Notching of the C-channel should begin tomorrow, so I will try to post the first round of pics then..
Thanks!! We hope it will come out as well as we plan for it to, so fortunately we have a lot of time to work on it! Our first show for it (this will be shown at stockshows in the Ag Mech competitions) wont be until this coming december, so hopefully we have enough time to get everything done right the first time!
Hate to be a buzz kill here but you guys should really be wearing gloves and at least sleaves or jackets.
Haha we normally do actually! But with us attempting to get the frame square, and getting everything tacked into place, the jackets and gloves were more of a hinderance than a help, but when we actually weld it all up, and we're doing full on welding rather than just tacking, we'll be fully suited up (or at least I will be!)
I would love to see how the smoke/heat comes out of your firebox and goes into the smoking areas .
Is reverse flow or some kind of baffle system incorperated into your design ?
How are hot spots being prevented ?
Honestly even I'm not really sure yet. I brought this up with our sponsor and he hasn't decided yet, but the way we drew up our plans, I think he wants to just let the smoke rise naturally. As you can see in the plans, the fire box and smoker are on opposite ends of the pit, and since the smoker is offset upwards, it should just rise naturally, while keeping a pretty steady temp.
I know he also wants a removable water/drip pan in the first section of the pit, closest to the fire box, so we may incorporate some sort of reverse flow in which some of the heat/smoke is allowed to continue on into the rest of the pit, while some stays in that section, but since everything is still in the works for that section of the build at the moment, everything could change in a minute..
Finally got to work on the frame of the trailer again today! No new pictures because it was mostly tedious work.. The right hand side of the frame warped inward towards the center over the weekend. Had to expand one of the center braces to keep it from warping inward, so that the width of the frame will remain at 66", and once that was done we re-squared everything.
Going to have my ag teacher double check the work tomorrow during class, and we hope to have at least one side of the frame welded up by tomorrow evening, if not both! Pics will be coming as soon as that is done, and once its welded we can attach the tongue of the trailer. Hope to have it rolling on its own by May 1st!
Frame is officially welded together! Double checked all the measurements when i got to class today, and once everything was good to go, we went ahead and welded everything up! Got half of the welds ground flat today in class, gonna grind the rest off tonight, and get the tongue cut and centered! Hope to have that finished, and flipped so we can start hangin axles by next week!
Looking over the design you're modeling your project after, I'm thinking in the barrels you're going to want to do some sort of reverse flow setup. I think you'll find one side of the barrel will be much hotter than the other. For the box/shelf portion, I think it'll be less imperative being that it's on the opposite side of the trailer from the fire.
Just some thoughts to mull over! It's looking good so far!
