What is the best way to remove a mink from stretcher when i forgot to use a bellyboard? I tried placing them in the frezer for a couple of hours. did not work.

tap the nose of the stretcher on the floor with a sharp rap. this will usually break it loose. always use a belly board. hope this helps.

if what fossil said dont help if you have a freezer you use for fur stick them in the freezer for a few hours then take them out and try to take off the stretcher then and tap on the nose also...

If the above doesn't work wet down paper towels wrap mink with the towels leave set over night, insert belly board, dry again.
It works I know this from experience, been there done that!!

put the whole thing in the freezer for a day.

I have split boards for mink in 2 different sizes .No problem comming off those boards .

put the bottom of the board in a vise, put on leather gloves or mittens to help your grip and pull on the pelt.

take a winkler tail zipper and start at base of belly and rip it hard as rou can in a straight fashion, this will create a cut where the bellyboard should have been. When you take your fur to the buyer you will see a signifigant price decrease due to docking. This will teach ya to not get in a big hurry on something you spent so much time catching.

LOL

the towel trick works.... it also works on cats that have waited to long to be flipped.
