Back over the summer when I was building my fur tumbler many asked me to tell how it works when I get some critters to dry.  It was the best time I ever spent.  It works great.  You can take a coon that looks like a drounded rat and 15-20 minutes later it comes out fluffy and beautiful...fur standing on end!!
The sawdust also adheres to all openings, eye mouth, vent, and any .22 holes.  which makes for a clean job!
Thanks again to those that helped me...mainly you wacky...I still think your really a scientist or something with all the math formulas you know!!
