I finally got a riser to work right for thin castings after 20 years of fighting it
For years I wasted time with giant risers on small ductile iron parts at the shop near Pittsburgh. Last month I tried a 3/4" insulating sleeve on a 2" tall casting and it fed perfectly without the extra cleanup. The old timers always said you need mass but this little trick saved me about 15 minutes per mold. Anybody else find a small change that cut their scrap rate way down?

A buddy of mine over in Ohio tried swapping out his standard sand mix for a finer mesh on some thin wall stuff. Cut his scrap on those little valve parts by almost half, just from that one change. Said it felt like cheating after all those years of heavy risers.

Ohio guy gets to feel like a genius for one measly sand swap, big deal.

Small changes like that are everywhere once you start looking. My buddy redid the gutters on his house with a steeper angle and stopped having to clean leaves out every month. It's funny how one tiny tweak can fix something you just accepted as broken.
