Read all the test, my question is : hole size? most bit sets start off with the smallest 1/16 size. How big is this compared to the .o45 I never was good at math :(
Found a conversion chart, looks like 3/64

I have found that the best size hole is about as big as a push pin.

Check this chart (http://www.rfcafe.com/references/general/drill-sizes-numbered.htm)to find the approximate size numbered drill. You won't find them at your local Walmart. ;)
#68=.031 , #61=.039 , #56=.0465 , #52=.0635
Woodenarrows did a nice little YouTube video comparing two sideburner stoves and the relation of jet placement. Watch it here. (http://www.youtube.com/watch?v=iznwkGdlwnI)
Probably won't withstand the rigors of peer review by some on WB but still it's a nice little burn test with great commentary.
Happy stove building!

Actually, you probably can. You can buy this set (http://www.amazon.com/Dremel-628D-7-Piece-Drill-Bit/dp/B0000302Z3) there. The smallest bit it contains is 1/32.

lustreking-"Actually, you probably can. You can buy this set there. The smallest bit it contains is 1/32."Close, but by using the Dremel small drills you link to, you will be missing .039" which falls between 1/32 (.03125) and 3/64" (.0468). The only way to get all the sizes mentioned in the reference is to use the numbered drill sizes I mentioned. I'm still pretty sure that you won't find them at Walmart.
Those of you that have read the information gathered by Daren, what are your conclusions about hole size and placement?
12 holes seems to be the ticket and the .046 looks good to me, but what do i know...lol

Pass the information off to a new stove maker:)
