Speaking of beaver,which are likely the thickest pelts,at low humidity and cool temps (50f) I leave 5 to 7 days before taking off the board.When cased pelts dish out like that when hanging it is likely from taking them off the board a bit too soon.This can also happen if dry pelts are subjected to changing humidity.

Tony,its OK to fire up the wood stove in your fur shed when you are working in there.Just keep drying pelts far away from the stove so they don't get hot.I have dried lots of pelts in the bush at trapping camp,hung in the far corner away from the stove,with the wood stove going at night.After they are dry though I store them in fur bags in the woodshed.
If you scrape your fur clean(grease free) a lot of the drying issues will go away.

I try to get them pretty clean. I keep fans blowing directly on the fur when the stove is burning to insure they don't get cooked. my sheds only 12 x18 so the option of staying far away is out. But I try to keep the heat towards the floor. I have a squirrel cage fan over the stove pointing towards the floors as the heat rises it pushs it back down.

I have a rack on wheels that I can place my beaver boards on. Then I have a large fan directed at the hides. I also turn the boards every day so one day the noses are up and the next day the noses are down. The nice thing about the wheeled rack Is I can push It out of the way when I'm putting up fur Then put It back Into position for drying when I'm done for the night. This would be a must for small shed operations.

BEAV CAN YOU POST A PIC OF THAT?

I'm so computer challenged that I have no Idea On where to even start.

The cart Is 6' long and 2' wide. Both ends have 5' standards. The bottom has a section of OSB for a floor. I then nail 1x2s with about 1" between them. That's where the 1/2" or 3/4" boards slid In. I like to have about 6" between these 1 x2s. That will give me room between the hides for good air circulation. And I like to place a hide on each side of the boards.

Do the same thing on top but here you only have to use a single 2x4 with the same slot configuration. This Is all you need to keep the boards In place.

You can build this out of anything. Take a 6' section of plywood and screw 4 castors to It Not beaver castors LOl. Then I would screw some stiffeners On the bottom side to keep It from bending In the middle. I made mine out of angle iron and square tubing.

ok I got a good visual from your description. I want to do something similar but im running out of floor space!lol and head space isn't much better! ive out grown my tiny shed.

Nice thing about the cart Is you can shove It outside while your working then move It back In when your done.

That's a good idea Beav.
