Well I have been reading a lot of the how to tan and tanning posts and gave it another try. I had previously tanned a few beaver using the orange bottle solution and the conclusion I came to was-
1) Don't try beaver first if you have never tanned a hide before
2) Don't overlook or underdo the thinning of the hide (especially on beaver)
This time I used Trubond 1000B and am quite pleased with the results. I also started with some easier hides (tame rabbit and wild mink).
All were tanned with Trubond 1000B except the mink on the far right. The female mink was done with the orange bottle tanning solution and turned out just as soft as the others though the leather seemed slightly off colored.
The rabbit leather was a brilliant white color and was nice and buttery. I did learn that I did to be gentle when working with rabbits. They are not as tough as beaver. The mink were nice and soft. I am not sure what caused the one mink hide to be slightly yellow (tanned with Trubond). Maybe some residual fat yellowed it. I had stretched and dried them last November and just tanned them.
Had a problem with the mink hair coming through the leather side. Any ideas why? Did not happen with the female tanned with the orange bottle tan.
