I used to do taxidermy and I have a tumbler with a 55 gallon barrel on it that I used to put hides in to fluff them up. I was thinking of making it into a chicken plucker, but not sure what the average speed is for it to work right. My tumbler turns pretty slow. I'm guessing maybe 30 to 50 rpm. On the other hand, I wonder if slower isn't better because it won't beat the birds up as bad. Any information you can give me on this would be greatly appreciated. I gave about $500.00 for that piece of equipment, and I sure hate to see it just sitting around if I can use it.
