Not sure Cat what you mean but "tube skinned" but if you mean cased, and like a muskrat, that's different.

We hooped them and slit them from blowhole to nose and rolled them as we skinned in what would look like a Christmas Manger contraption.

Easy? April Fools! I've rough skinned them kneeling in snow banks in MT many years ago when young, and would dull 2 good skinning knives on a beaver!!

AS for the rest of your questions on skulls...there is/was a recent thread on 'tried a few skulls" or something like that where the chap outlined a method he used and others chimed in.  Check your search function and see if you can locate it.

I have teeth that easily slid out when the skull dried... dang...they go forever up in their head!

Tube/case yes that is what I meant and did. I have skinned them before as you mentioned but that is a lot easier when you have a full slit up them! Yeah I have a couple of skulls also .... Those teeth are amazing!! I will look to find that post! Thank you and thanks to all for their nice posts! Had to take a nap today! Hunting with Mr. Chuck will wear you out!  

Congrats. Looked like a fun evening.  

Congratulations! You had a very good March.I think you and your Tornado are doing fine. By the way everyone,she had me build her Tornado to match her Camero.    

Congratulations    

 Yes I did! You did a fine job and they both make me do the happy dance!

Looks and sounds like you had and are having a great time with your Tornado!
