Awl--
Got off the phone with Hadco, the big-dick alum supplier in these parts, and surprisingly, a lot of stuff is about $2.50 a pound, not that much higher than a year ago. wow... It's just a matter of time tho....
OTOH, ahm fixin to buy a 5/16 radius concave cutter from a 2006 MSDS catalog, $49 (Meda import), but, uh-oh, NOW it's $96!!!! goodgawd....
Apropos of JRW's excellent posts/logic, man, for one'sies/two'sies, this is a real kick in the ass, yo.
And, it's just going to get worse. Which I will explain in some detail in the upcoming New PV Economics.
Maybe this is now a Starbuck's Concave Cutter....
