Hey guys

So I've been on a hunt for a 250 gallon propane tank here in Cali and I finally got one. My question is about the fire box. I really don't want to screw it up with the size or the opening between the cook chamber and fire box. I know some people cut out the bell and put a 1/4 plate for fill. Is that a better portion vs not cutting it. I just recently built my first RF offset and it was horrorendous, mim constantly fighting temps and keep it running evenly but I see what the problem was and quite frankly it's really not worth the time or effort to fix hence the upgrade.

I'd like to go with the more traditional route vs rf this time around I feel it will make my life a little easier. Any insight or help would be much appreciated

Thanks in advance

If you want a warmer on top your firebox then removing the dome is a plus. If you are just building a regular offset with tuning plates or just open then leaving the dome allows you to connect without taking off the dome.
I took the dome off my Hybrid for adding a warmer I like it that way. Here is a link to the build without all the posts.

Thanks KAM!!! Couple of questions for you, how high is the cooking grate from the opening of the cook chamber, also how many tuning plates did you need for your pit? If I left the bell on but made and ext on the opposite side for the exhaust how would I compensate for that extra volume? Also do you suggest an adequate fire box size, thinking about going square. Sorry for the barrage of questions just want to make sure I build it good this time around

The top of the grate is 5.5" from the opening. I have 8 plates when running reverse flow and use 7 while just tuning plates.

If you are just talking about a plenum for the exhaust to rest on just use the regular numbers do not compensate.

Also do you suggest an adequate fire box size, thinking about going square.
I like slightly over sized and will go as large as 25% but no larger it just depends on the build I am working on.

You are very welcome. I am glad to help. Very Happy

Thanks again!! So i ran my calculations on feldons calc, but the major obstacle I ran into with my RF was the hole between firebox and cook chamber.

My problem was how to make is wide and tall enough to get the square inches.

My calc show 20.68in but not sure what that means lol forgive me. But is that suppose to be 20" height?

heres the link to the cal

That is 20.68" wide. x 10" 3/8" tall. I would go 23" wide x 11.5" tall and have a 1.5" grease bridge.

Last one i promise lol, for your baffle plates are each the same size in width? and what about the gap between each of them are they are all evenly spaced? Im worried about not getting enough smoke to the meat if the gaps (if any) would obstruct it. Thanks again KAM!!

They are all the same width 7" I believe. The gaps vary on my cooker. Starting at the firebox it is like the first plate closed to the deflector then 3/8" 3/8" 1" 1.5" 1.5"1.5". You will get plenty of smoke dont worry. Wink
