I have already entered the recipe into my account at insight-live.com, assigned it a code number and printed a mix ticket for the total I want. I have a scale that tares to zero after adding each material. The slotted dust hood sucks the dust away as I add each. When I pour the dust into the water in the pail, a lot of dust is generated and this hood is even more important. Normally I used a big enough bag that I can seal the top and shake the mix together before adding it to the water.
