      Excellent manual.  Much of it was over my head but the part about the bottle riser makes a lot of sense i am going to try it to solve a shrinkage problem i am having. 

      Thanks for sharing!

      I find this PDF manual a pretty good read:


      It applies to iron casting but I assume its generally applicable to
      aluminium too.

      One point they make is that runners should be straight, not curved.
