I Couldn't weld before building this, some might say I still can't.

To move forward with my design I want to clarify what Towtruck has said above to be sure I understand.

Because of the design limitation I have, the best I can get my throat size is only 95% of what the calculator says. If I make my BG larger will that help compensate for the smaller throat? Maybe also a larger chimney, 8" instead of 6" with a damper for control?

What if I oversize the FB slightly and air intakes? Will that help with heat and airflow?
If your hole out of the fire box is 95% I would make the gap under the bypass plate 100%. The restriction of air through that 95% opening won't be noticed as bad as long as the air has the right size to continue on in. Bigger air intakes are good but making the fire box too much bigger should not be needed. The damper on the stack should take care of any issues with the exhaust. Most pits are designed to run with the stack wide open and the temps controlled at the fire box.....but that is not a firm rule. I have ran mine and others do too with the stack damper helping control temps.

The gap at the end of the BP doesn't need to be larger than the throat. It can be up to 25% smaller than the throat but never larger. The BP gap has a few functions, 1) it allows the heat to build up under the BP which gives you the radiant heat. 2) it controls the velocity of the air flow across the cooking grates. As towtruck said above I would build everything the size that the calculator recommends and the throat would be the only thing that's not properly sized and I too don't believe that you'll notice a 5% difference.

OK guys. Thanks for all the input. I will get starting finalizing my design and maybe post it before I start building.

Another question:

Because my CC and WC will be built with thinner gauge steel instead of 1/4", would it be a good idea for me to insulate both the CC and WC as well as the FB?

Well... You guys convinced me to go for it. I saw a sale at one of the regular suppliers I go to and bought a small Miller Mig 130 and all the stuff to get started. So I guess my first welding project will be to build my FB and all the racks.

Any tips on how to get started? Any good videos out there to help learn to weld?

Congratulations on the new machine. I guarantee you will soon wonder how you got along without it.

Play with some scrap material first....but have fun!

If it's tourist season, how come I can't shoot 'em?
