I also use this technique. None of the local stores
here including HD had 12" non-ferrous blades, so I got
one from McMasterCarr. The "metal cutting" blades
that were available in local stores were for ferrous
metals only. We have a band saw where I work. The
blade tends to wander around especially on a large
piece like 4 inch diameter, it is very slooow.
My 12 inch miter saw works better and costs much less
than a band saw. When you order the blade, also get
a stick of cutting wax for the blade.
