Hi, I,m new here but I,ve been really impressed by the Visco machines your building. I did notice though that a few of you were having problems with the powder feed funnels clogging and were going to put vibrating units on them to help. I think a better, simpler solution might be to use the same as the commercial machines and feed 2 additional strings into the top die through the powder funnel. This should prevent bridging of the powder.
