Erez,

how did your snuffer work when you tested it? Did you weight it? What grit did you fair and sand it down to? Does it work equally well from both sides?
Lots of questions, but I find it interesting..


A note of warning. I noticed you used your shopvac to pull vacuum when bagging it. It is very probable that the motors uses the airflow for cooling, so when pulling a vacuum your motors run without cooling. They may burn and seize, or start a fire that way. A compressor from a discarded fridge or a air-conditioner would be much better (but take care if you fiddle with the wiring yourself, so you dont put current on the housing of the compressor).
