I've done a number of fox and over the years have experienced on some of my early jobs hair slippage on ears and legs that has been discussed pretty extensively in the archives. I've learned a lot from the archives but just encountered a problem with a grey fox I've just completed that was unexpected. I've begun to apply stop rot to the ears and legs while I'm thawing the fox when it's frozen whole, and then skinning as soon as it is thawed enough to work on. I've tried to minimize my working time while fleshing, and double salted the skin until dry, then pickled (1 ph), washed the skin in Dawn, and then use McKenzie tan. I had no signs of slippage throughout pickling, washing and applying the tanning cream, but had to freeze the skin until I could finish it. So I took the frozen, rolled-up skin out of the freezer, let it thaw, and then began to mount it. As I was working the skin over the form, I was horrified to get some hair slippage around the shoulder. The ears and legs were tight. I managed to get it all put together with minimal handling and the hair is long enough to cover the few bare spots that occurred. But I'm trying to figure out where I went wrong. I do have a problem getting all of the thin layer of fat off of a thin skin like a fox (I'm going to start using my wire wheel bird degreaser, based on what I've read in the archives). I'm thinking I may have left a thin fat layer on the area of slippage. But if that's the case, I would have expected to see the slippage when handling the skin for pickling and washing. Is my sequence of washing to degrease after pickling wrong and could that have contributed? I know the pickle bath was between 1 and 2 ph the entire time, so would think any bacteria were killed at that point. Any thoughts and ideas would be appreciated; I'm getting kind of paranoid about fox!
