Designing my first smoker and I have a few questions

Postby Aaronp0412 » Mon Nov 20, 2017 10:40 pm

I recently came across some pipe for pretty cheap. My cook chamber is going to be 5’9” and the fb will be 2’. They are both 3/8 thick and 2’ in diameter.

On the opening between the cc and the fb it’s at 11.72in for the height and 20.62in in width. That’s including a 1.5in grease darn. Should the tuning plates be right above the top of that opening in the cc. Also at what height would the cooking grate be above that.

Forgive me if I’m leaving out anything. This is definitely going to be a learning process for me.

Thanks for your help. I’m sure I’ll have a few more questions along the way.

I set my tuning plates 4.5" to 6" below my top grate I prefer 6' if I can get it. To do this often times I use a 6" wide deflector plate angled down at the firebox opening. I do not like the deflector to angle more than 25°if I can help it.

Thanks for the help. I hadn’t decided if I was going to do the top grate or not yet. Do you ever feel like it’s to crowded with the two grates?

In a 24' chamber top grates get in the way if you're cooking large cuts as there just is not an easy option for spacing. When I cook full turkeys I pull my top grates out or just stack them on the lowers. I do not regret having them but rarely use them at competitions.

Thanks. I think I may just go with a one level for the cook chamber. What do you think about adding a vertical smoke chamber. It would be the same diameter 24”. My cousin has one on his smoker, he seems to like it. I’m just not sure how to calculate that with the Feldon calculator.

While I do not care for them a lot of folks do like them. As for calculating it if you are placing it on the end opposite the firebox no further calculations are needed as the warmer will be acting as your exhaust so all you need is to add a 6" exhaust about 12" tall to the upright.

How many inches above the tuning plate is your bottom grate?

Is there any reason not to use a 6 inch pipe for the exhaust? I just like the way a 6 inch pipe looks. The calculator calls for it to be 19.21 inches for a 6 inch diameter.

I think my exhaust hole cut out is going to leave about half of the 6 inch exhaust below the grate level. Is this going to be a problem? I meant to have it right above the grate, but I guess I messed up some how. Any advice would be appreciated

I’m also not sure if the firebox to cook chamber opening is the wrong size. I had went off of the planetcalc for some reason and it seems wrong to me know. Not sure how I got that before.

If KAM see's this he will respond and help you out. He is the resident expert pit builder. Although he has not been on much lately. If you look up the feldons calculator on here, I think there is an email address on it that possibly goes to KAM.

I didn’t have any luck finding a email. Hopefully he will pop
In soon. Thanks
