One of the problems with power carving is the dust that is created. Some woods have very toxic dust that can cause breathing problems as well as allergic reactions, for some individuals. I am happy to say that I have solved that problem. First you find a beach in Florida with a beautiful beach house.
All beach houses have porches on all levels that face the water. In my case it's the Gulf. At some point in the day there will be a strong wind blowing. When this happens, you place yourself on the porch with the rotary tool and your wood. Position yourself so that when you power carve, the dust created will blow away from you (and others too). The only problem I have to overcome is the motivation to sit and carve several hundred animals..
