Might want to leave yourself at least 1/2" with that size of leather. At least the first few times you use it.
However, I was just thinking that you might be able to leave the leather on the table and move the Jerry Stripper instead of the other way around. Never tried that, but it might work for a large enough chunk of skin....
Maybe cut a small piece of wood to mount the stripper on and use as a handle??
Just thinking outloud...
