I got a fox in that was road kill and the inner ear slipped completly and the black tips slipped on the backside as well. I would normally repair the skin prior to mounting but didn't have time because the whole thing was slipping and it's been my experience that when this happens you want to get it on a form and don't touch it untill it dries so that is what I did. I purchased a fox face off e-bay that was dry tanned and went to work on the repair. I cut the ears off the replacement skin and peeled the skin off the back of the cartilage and then carefully removed the inner skin. I layed the inner skin on the inside of the ear and will blend the seam in the inner ear canal when it dries. Since I have never repaired a fox ear this way and was basically winging it as I went at this point it looked like it was going to work well and I though Oh crap this would make a good tutorial so I grabbed my cell and started snapping photos for the repair on the back side of the ear as I went. So here we go.
On the back side I carefully removed the slipped skin off of the bondo ear. ( remember George always said bondo isn't an adheasive) and where the good skin was I carefully lifted it off the edge so I could tuck the repair that will be shown later.
next I trimmed the repair skin slightly larger longer than the repair because I didn't want to tuck too much and create a bulge just wanted enough extra to hide the seam
Next step was to use good hide paste in this case roman 555 don't worry about getting on the edge of the hair as you can wipe it off with a damp rag after placed and anything left will pick out.
this is wear I tucked the edge.
and here is the final repair
Here is the over view of the entire mount, for what the customer brought me and expected me to work miricals on, I will take it and I hope he will to.
It literally took me longer to upload these pics and write this out than it did for this repair on both ears. I hope this may help someone because I had a few sleepless nights trying to work out in my head how I was going to do this.
