So bowEd how do you keep the fat out of the hide? What we did was first skin it (it was fresh road kill)
Then it was put in a the freezer for a few months until we could get to it, then we cut the fat off not fleshing and membraneing with a fleshing knife just cutting meat and fat off with a sharp knife so we don’t damage the fur with the fleshing knife, then we salted it and tried to dry it to flint dry but it never really dried, tried to membrane it but it was really greasy…
You said you fleshed it.Not really so.By only cutting the flesh and fat off with a knife it was'nt properly fleshed and you left a lot of fat film on it yet.I've never had them loose hair from fleshing on a beam with a fleshing knife from a fresh hide or a frozen fresh hide.
If that happens your road kill hide had been setting along the road too long.
It can take an amount of practice to learn how to flesh properly on a beam.
