MossCreekMonster, I have tumbler.
I took heating element outa clothes dryer. When you have back off dryer, duct tape holes in drum. Also duct tape over lint catcher.
<span style="text-decoration: underline">I use course, corn cob grit</span>. (Fine grit or saw dust gets into everything, cracks and such). I recommend the course grit.
It's learn as-you-go process on drum'n fur. How much grit? How many hides at a time? How long should I let 'em in? When do I replace dirty grit? After a few hides, you will get a feel for how long and how many. I use a shop vac to remove dirty grit.
I drum Coon (after flesh'n, skin side out) for a few minutes, this really takes off excess grease.
At times, I drum Fox and Coyote (after flesh'n, fur side out) to clean up blood or mud. I also add a dryer sheet or two on fur side out fur.
Having a tumbler, gives me another tool to care for fur.
Trapperrick I have thatthere NAFA dvd. Great info for sure.
I don't feel I over tumble my fur. I don't want them bone dry or damage the fur. Easy does it when tumble'n.
Slightly drummed Coon..
