copperjoe,

I prefer Lenox Diemaster II blades and use the 10/14 Vari-Tooth in 1/4" for probably 90% of my work on the vertical saw. For what you're doing with stacked thin sheet, I can' toffer a good recommendation - every time I've tried that with soft non-ferrous metals, I've serious problems with swarf from the upper sheets galling the succeeding sheets and gumming up the cut. This has resulted in a very poor edge profile that required excessive finishing, so I have opted instead to have such things cut with either a waterjet or special laser. Copper is nasty stuff to cut, at times.

I'll be very interested to hear how you make out with this project. Hopefully I can learn a new trick or two from you.
