Ah...I remember it well, the utter confusion, the headaches, frustration, Chocolate.

Math is not my strong suit. I *think* this would work, but wish someone with experience could confirm it. I do not trust myself!

Mine either but it really is made simple if you have a Barley Box style system. Then you just have to measure the opening. Viola! Your done. 125 CFM per sq. foot of opening.

Mine is 2'X4' 2 x 4 = 8

Eight square foot opening. 8 X 125 = 1000 CFM needed for my work bench area.

As for hood size, I was figuring whatever that standard range hood thingy is would suffice. I read online that that is usually either 30" or 36".

That would be 7.5 square feet of opening.

7.5 x 125= 937.5 I think. That is the minimum CFM you would need



Please do let me know if I am totally out to lunch, it is entirely possible!)

You are fine just going through the lampwork growing pains. We have all been there.

Hope this helps.
