The issue of the turbines ingesting the powder has been discussed, slept on, thought about...even drank a few beers trying to resolve the question. The protective screens on the Wren motors won't protect from the finer ground (ie: flour)...but I thought maybe a rough ground pepper may be heavy enough to fall below the engine level...with the hopper full of flour...the stuff REALLY comes out!! Any constructive ideas are welcome...as I would love to offer this idea to all the Hog owners.

I even thought about putting a smoke bomb in the hopper????

Only time and trial will tell!!
