Jay Whaley of designed a fabulous small and movable system for small metal castings called a WHIP (ideal for Delft)
You can see a demo of it here Ganoksin - BenchTube - Wire Handled Ingot Pouring- Jewelry Making Videos
It seems to be distributed by Eurotool and I noticed you seem to have his HEETRIX soldering arm & was hoping you might start stocking the WHIPS too
Any likelihood you might be able to get them?
