Ok. Thanks. My buddy ran the calculator on his computer yesterday and I will post the results when I get them just to double check them before we cut out for the firebox.
We are going to try and drop off the tank this week to get it sandblasted. We also cut the 3 upper door drafts. We are going to use the screw down type like you see on older wood stoves.
You should contact Gary and ask him.... It looks like the firebox vent opening are incorrect to me, but I don't know what goal he had in mind....
It appears the upper and lower inlets are reversed.... the lower should be the larger number and the upper, the smaller number... the upper air inlets bleed small amounts of air into the CC for temp control and moving heat from the FB to the CC.....
Total sq. in. opening, for the FB should be around 30 sq. in. I suggest ~20-30% upper air inlet and ~80% lower air inlets... I'm not sure what "high" and "low" designate....
Below is my calculator/tutorial... it is a "manual', crunch your numbers... I know it is correct...
Thank you locovet for being understanding. I corrected that issue an will work to get it finished. I wanted to make an easy to use RF calculator for anyone wanting to build a smoker. I want to make it the best it can be. Members reading this are welcome to give me input. It is in an excel format and I realize not everyone can open it up. Maybe I can fix that as well.
I'll be looking forward to watching your build as it progresses.
Not a problem gary. We are going to keep the top vents like Dave said but probably only end up using the middle one. We still haven't cut the bottom drafts yet so we are ok there. Thanks for looking and checking over.
Gary, at least you could go up and help him correct the openings. After all it's not that far from East Texas to Oregon. Since everybody is reading this, let me thank you for all the help you have given me. It's hard getting started on the right track with a new forum and it's folks like you, with all of your experience who make it enjoyable. Joe
