coldplate thickness

[g.l.amour]

how does the coldplate thickness relate to a large or small core (lets say P4 or Tbred)

i have some copper bars lying around that are 10mm thick, that is prolly way too much. the idea is to use in the end a tbred B. that prolly requires a fatter coldplate (to distribute the small heatsource over the much larger pelt surface).

anybody have a build drawing of how to attach the coldplate to a standard WB?

aaight, back to google

thx
