Kevin,

At the link shown earlier there is this info: " 
Drawings for making the chassis parts are here:

For heat sink material, a heat sink with a base 
thickness of .300 or better should be used. The 
size of the one I used was 8" long x 5.375" wide."

Not my cup of tea; not into 2 m from my location 
(was 20 years ago, and broke my pick due to poor 
location).

73, Phil W7OX
