I am very interested in getting into LN2 and/or Dice, and i happen to have the tools necessary to put CPU pots together, using either steel or copper.
I was wondering, would it be a good idea to make an LN2 or Dice pot out of steel? Or is it much preferable to make it out of copper- i know copper has better heat transfer capabilities, but it is also a LOT harder to efficiently solder together copper than it is to weld steel metal together. (for me at least, other people may find it easy to solder but I find that i am much better at welding, for whatever reason)
So basically, is steel an acceptable materiel for a CPU pot?
Also, does anyone have recommendations for how large to make the amount of metal between the CPU and the LN2/DIce? I.E. how much metal would make the pot be a fast pot, vs a slow pot.
I was thinking about taking some steel pipe, good 1.5" ID and ..25" thick pipe, and welding a hunk of steel to the bottom, being around 1" to 4" (depends on what kind of thermal properties steel has) and then i have a pot. May find a larger pipe, or something but that is the basic idea.
Could maybe do a square design, if I can't find any pipes with large enough inner diameters. 1.5" is semi-ok, but 2.5" - 4" would be preferable.
May just do it in copper though, with a similar design but soldering rather than welding.
Thanks for any input!
(and heres what kind of pipe i was thinking of using, not exactly what i want but is fairly close: http://www.homedepot.com/p/Unbranded-1-1-2-in-x-10-ft-Black-Steel-Sch-40-Pipe-GS11-210BTBE/202310232
