I saw a random you tube videos of these and may try to make one out of some scrap I have.
My question is on the best layout as far as the length of each arm.
Should A (the chimney) be longest? Is longer better?
Should B (the feed tube) be shorter than A but longer than C?
Does the length of C even matter?
Also would it work to make this type of set up to help feed air to a larger campfire on top? I will try to find a picture of what I am thinking of on this.
