Looked into some 1/4" copper rod (you would just have to thread a little bit of one end using a tap & dye set) and its about $18 for each 1/4" x 12". I have lots of holes.
It would be cheaper for me to make a new pot from scratch but I like the idea anyway. I would have to incorporate it into the initial design and use a single 12" rod and cut it into pieces.
EDIT:
Found same 1/4" x 12" rod for
$3.23 DOUBLE EDIT:
Found
Alloy 101(99.99% pure), 1/4"x 36"
$12.72 at my favorite, McMaster
Part # 8965K123
My next order from McMaster will probably include one or 2 of those rods. Excellent idea Mr Beef.
