Gravity fed smoker

Post by Matt318 » June 20th, 2018, 2:27 pm

Are there any calculators for gravity fed smokers? I have the main bulk of my design modelled up on the computer and now i am just running through tweaking and adjusting things and i want to ensure the FB, ash box, heat transfer pipe, vents etc are the right size and of course the chute too. Can anyone shove me in the right direction or give me some pointers?

Are you building from the plans (smokerplans.net)? Or are you winging it from pictures etc? I'd say most of the guys on this site have built gravity feed smokers from the plans. And as far as I know there are no calculators for gravity feed smokers... I might be wrong, but I've not found any.

It is all about the charcoal burner (BTU) vs the cubic inches of the CC. Frank might answer your question on a PM. But I personally recommend the plans for this one type of smoker.

I have bought plans but i want to make some modifications. i am converting it all into metric for myself before i start building as inches are confusing for me, most material in uk is sold in metric too so it will just be easier. I am tweaking some aspects of the design to add a few features that i would like and the CC size is going to be slightly different to the plans and i just want to know what calculations to run through to make sure the burner is still the correct size to cope. If its just a case of using the ratio of burn vol to cc vol in the plans i have then i will go by that but i would like one of the pros to confirm for me before i start pouring cash into it.

According to Frank you can make the CC a tad bigger than the plans and it will be OK. The figure 125% springs to mind, but I might be wrong. Check with Frank.
