Hi Dave....Euro ??
Anyaway....its the powder in the bottom of the tub I do not trust.
I looked at making a system for this technique, however I gave up due to the heath protection problems, primarly due to that powder resadue as well as not being able to establish a standard" as the alloy varies between sets ? so I dropped the idea. (due to legal reason I will not name the maker of the tracks I tested)
It is sheering valve that is not yet connected to the shivering tap so hence it deflated
