Thank you for your time drawing the skiz, realy apreciate it!
One thing is certain. I will cut out the whole trunk bottom out. Well, not the whole actual bottom, just the muffer part. I hoped to get by by only cuting a hole in it, like seen in the video, but it aint gonna work.
Ok. Now, l feel more building/designing freedom.
Now, for the question mark on the skizz. How manny tubes? Any ideas? My math says 10 feet of 2" pipe is same surface area as the hopper mantle. Thats about wk 9 pipes. Enough?
Haha, correction to you too JO! Hot air exit to the bottom. Otherwise heating the trunk
A nother note. Will the whole thing work with cooling pipes on only ~ a third of the hopper? I mean the internal heat circulation…
