[TCML] primary material? (interview)

[bartb]

Hi Nicholas,

Yes, all metals are up in price everywhere. It makes choices more 
difficult. Copper is up about 50 cents/lb as well as aluminum. The 
difference is $4/lb with copper versus say $1.50/lb with aluminum (just 
looking at scrap rates). Anyway, you could build the primary with 
aluminum tubing. It's sold in the hardware stores also and is certainly 
an alternative.

Take care,
Bart
