Cows Horns

There is a process referred to as sweating them off. Do a search and get some ideas on how that's accomplished. It might work for this situation.
Not sure if this link will work, but you can do an advanced search for sweat.

Absolutely use the Advanced Search on here on how to do that. There is even a post on here where someone had a Watusi I believe that they used ratchet straps to get them off. Don't remember who but search for Watusi horn removal or something similar and you should find it.

 

They are a pain because of how big they are - my pot will fit a Buffalo skull but only about half way down a watusi horn - I still boil the horn and get it hott and hope the heat goes all the way down it….. then tie the skull
To something that doesn’t move and then a couple half hitches around horn and i come-a-long them off very carefully……

watusi are the thinnest brittlest horns I’ve ever done ….. it amazing how thin they actually are compared to how big they are ……

once you do get them off the end will warp and turn up really bad when drying - I put a whip cream or sour cream container in the end of them ( or what ever size best fits ) with a big hose clamp around them and snug them down to keep there shape -while drying …. works good for me …. Good luck !
