I know there is alot of diff of opinions out there. I want facts... What do tanneries do different than in house tanners? I turn, flesh, Salt, rehydrate w/ salt, kemal-4, & Skin Prep NBU, then Pickle, shave, pickle. Then nutralize. Then Lutan-F, rinse, liqua-tan, sweat overnight, rinse and freeze till ready to mount. I feel by doing them here I can have a faster turn around, can get the hides thinner, and have less chance for damage in the tumbler. There are some that think my hides will fall apart or have bugs in a few years....Am i missing something?
