I tried a different riser sleeve on a big steel casting and it totally failed
We had a 500 pound gear blank pour in Tacoma last week and I swapped our usual fiber sleeve for a cheaper ceramic one to save about forty bucks. The riser froze up way too fast and we ended up with a massive shrink cavity right in the hub. Has anyone else had this happen with ceramic sleeves on heavier sections?

Man that's a brutal lesson on forty bucks. Seen similar things happen when the insulation just isn't right for the mass.
