Any one have or use one

never heard of that.

Do you mean a fleshing machine , used to thin hides and capes as in taxidermy?

Your talking about a round knife.

John Epler had one similar to this:

Furbuyer in Wes tpoint Iowa had one. His wife ran it sometimes but set idle most times as slung coon grease all over.

Thats a Mills Fleshing machine made by Lester Mills's company in Minn or Wisconsin. Fleshes with a hi speed hard rubber impeller. Pipe sticking out the left side is for a suction unit to pull fat into a barrel. Older models used a vibrating metal blade to flesh.

I used a vibrating knife model on coon and it did a good job, but was very slow. I used it a couple days while working for Pacific Hide and Fur in Gt Falls MT. I decided it was too slow and moved it out of the skinning room.

Also called a fleshing machine.

Yes a fleshing machine.
One is a table model the other is hand operated.
Uses a round spinning sharp blade.
the table model is $1+++. the hand job is $3++.
I've known about the table model but not the hand operated one.
Saw it on utube.
You can use them for fleshing and hide thinning.

Looks like if you could come up with a traffic cone looking thing and get it chucked up in a lathe you'd have one.

Google "The fleshall mini flesher"
Don't remember the site but I watched a video on utube.

I think those are more for shaving leather then fleshing green fur. I have seen them run and don't think that a person could keep up with someone with a good two hand fleshing knife. If you are wanting something for working rehydrated hides to tan, they are the way to go. That is what they are made for.
