I was planning to put together a manifold for the 70qt Coleman Xtreme I got from Walmart ($38) last week. I stopped by Lowes to scope out some parts and what I planned will not fit. So I am back to the drawing board. Here is what I had setup:
(Edit: the above diagram looks a lot prettier in the edit window then it does on a read. So just imagine that the vertical lines "|" connect the C's and T's)
The vertical pieces were really just enough copper to connect the corners to the T's
This measured in at 10 15/16 inches (the cooler is ~10 1/2). I was thinking I can probably shave enough off the T's to make it work out, but I'm not sure.
Palmer's book says to have space on the outside of the corners (X on the inside, 1 half X on each outside corner (so 2 inches between the corner and the first T then the outside of the manifold to the wall "needs" to have 1 inch). I'm assuming (since I was too lazy to completely read the book) that this is for uniformity in flow.
I also seen this design
for the Coleman 70 (on another board).
There was another pic that I found (I can't remember where, I'll edit if I find it) that had the manifold squeezed to the sides (maxed in size to help keep it in the cooler I guess?).
Any suggestions? Thanks.
