new smoker build question

Postby cparker2277 » January 12th, 2018, 3:04 pm

Hey guys, I'm having a traditional offset with tuning plates built by a friend and have a couple questions. My CC is 53 inches long(24" pipe) and the firebox is 20.5x20.5x20.5. My question is on the opening between the two. On the calculator it shows a half moon at 64 square inches. Half moon I'm assuming is a true half moon and wouldn't follow the curve of the CC pipe. My question is if I follow the curve of the CC pipe it will not be a half moon, it would be wider and shorter which to me would distribute heat a little more even. Is there any reason not to do it this way???

Keep to the square inches. Shape is not as critical. Mine is a trapazoid so have fun.

Welcome aboard!! :yth: as long as you keep the opening as high as possible on the fire box so it doesn't trap heat in the FB. If you look at the top of the main page you'll see the smoker builder calculators, Pete has designed a throat calculator that will give you the dimensions that you're wanting.

Thanks for the info guys . I will stick with half moon and keep it at the top of firebox . Do I need to leave a lip between CC and FB to keep grease out of FB?

Yes you'll need to leave a lip. I use a 2'' grease dam on my RF.

My reverse flow has a 1 inch dam but I agree with big-t to go with closer to 2 inch on a traditional offset. Nothing worse than a grease fire.

Okay guys thanks for the info, I will add a grease dam. It's going on the porch of my new food trailer so I can't afford to have a big grease fire. I'm guessing I put a drain in it to empty every so often? Or do i just scrape or towel it up?? Also does firebox size need to be as close to possible to correct by the calc or should I go a little bigger? I read somewhere 110% is what most people do. On my offset now its closer to 130% and I have to run a really hot fire to keep it running clean.

You could add a drain so if you needed to drain it during a big cook but I usually just scrape it out every now and then. The max on the FB is 115% so 110% will be fine.

Ditto on the drain. I have one but end up using a 6 inch scraper and a towel. The drain is overrated....
