Hi, have drawn a smoker in sketchup and want help checking that everything looks ok.

Will start building shortly, gladly accepting tips.

Welcome aboard! Your numbers look fine and the overall drawing does as well. I would recommend building a basket in the fire box to keep the coals all piled together.

Ok, thanks for the welcome and the complement about cad skills :-bd
Do you think the plate under the bp is a good idea?
It’s 1/3 of the length of the cooker and is supposed to take away the worst heat on the bp.

For info the fb is suppose to be insulated with 2 inches.
Should I insulate any more part of the cooker to get a good fuel economy?

Best regards and thanks for the help/Peter

Yes the extra plate is a great addition, we call it a shadow plate and it helps avoid a hot spot on that end of the BP. An insulated FB really helps with efficiency, most guys don't insulate the CC but it can be done. I'm not sure what the climate is like in your area so it's hard to say if it's worth the extra work and cost. I live in lower Alabama so we don't have a need for an insulated offset seeing as it only gets cold a few times each year.

I like the shadow plate. I didn’t put one in mine when I built it and had to go back and put one in. 1/3 might be a bit long tho.

No need to insulate the cook chamber...overkill. Insulating the firebox decreases fuel consumption, allows more stable heating and makes the outside of the firebox safer by keeping it cooler. Your choice in insulation depends on what outcome you want.

I also see you designed a grease trough on the baffle plate. Its really not needed. A perfectly flat baffle plate works best in my opinion.

I'd be tempted to put that chimney in the top, but those guys that commented above me know better than I do. Either way will work. I'd put a drain in the baffle just so you have it if you want it. Most guys just scrape the sludge I think. 2" seems adequate

Thanks for all you’re help, will be posting more pictures as I get going.

Is it a stupid if I go with a flat bp to cut the bp in several pices and have them lose? And put a drain in the bottom of the cc four washing out.The day I would want a offset I could just put a chimney on the other end and use the bp as tuningplayts? Or am I complicating things?

It’s best if you weld in the baffle plate. You really don’t want air/heat to leak up and definately don’t want grease to drip down. I ditched my traditional offset the day if I finished my reverse flow. I can honestly say I see no reason to ever use an offset ever again. People use tuning plates to make their offsets run more like RF—-why would you want to go the other way?

A 2inch drain is fine. I put one in but never use it as it’s easier to just scrape the crud with a wide putty knife. I won’t put one in my next build and it will save me $100 in the process as a 2 inch brass ball valve is expensive.

Just measured it, my shadowplate is 7.75 inches long on a 48 inch cook chamber. I’ve re-worked it several times and like it as is.
