Hit a few local mold making shops if you have any in your area.
I bought a few things couple years ago from a mold shop closing up.
Inquired about the pile of scrap metal and was told it was headed for
the dump if I didn't want it. Drove away with several hundred pounds of
S7, H13, and others, including about 10lbs of graphite. This was a small
shop, larger shops will likely generate decent amounts of scrap
graphite. Find a friendly owner, and you could end up well supplied by
hobby standards.
