Well I was out on the road traveling and am a little behind in getting this post up.
So here it is. Like Dave’s post earlier for a sheet metal cone, here is a straight tube that can be used for a holding tank or a pressure vessel. It will alow you to unfold it and get an accurate burn pattern. We can use a simple sketch and some construction geometry to create it.
Check out this video of how it works.
