The oil I got out of the frozen oil sacs is cream colored, I almost got a headache looking for hair! Gonna grind the empty sacs and see if I can find some hair?! I thought I knew something about beaver and smells?

I have found a good amount of hair in the oil sacs I have cleaned. So much so I keep a pair of tweezers handy to pick them out of the drained oil as best I can. The hairs pull out easily, not seeming to be attached within the oil sac. I will look better the next batch of sacs that I drain.

I've also not seen any attached.

I like to put a layer of salt in a glass bowl. Layer of whole sacs then a layer of salt. Keep going till the bowl is full. After awhile everything is stable. The salt takes on some of the oil. Is both an attractant and preservative. The sacs get dried and hard. Run them through my grinder and add to bait. When rain is being a royal pain fresh glands squeezed out in a flat set wont wash off. Not a great lure for predators but it keeps working. Predators like to have a sniff or two. Catch's beaver pretty good. I just make a slick spot on the bank. Put oil in the slick spot and and peel a few willow sticks and toss them on the bank.

Mine either, I can no longer skin beaver on the kitchen table or dry furs in the living room since I got married. Funny thing though, when she wanted to tan some weasels for a project she was doing, it was okay to do everything but the skinning in the house. For the first quite a few years that I lived here, before I had a good shop, I had hook in the ceiling of the mud room to hang a gambrel on and did most of my skinning there, and beavers were done on the kitchen table.

She will wash empty lure bottles in the kitchen sink for me, but I have my own food processor and grinder, I'm not allowed to use hers.

No one will ever agree to marry me so it's not a problem.

mixed oil from males and females separates into three layers (the jar on the left is 2 years old). Female oil seems to have some polymerized/oxidized stuff in it that acts like oxidized cooking oil, i.e. it's thick and sticky and becomes difficult to completely wash off even with soap. It could be a good thing for some applications like when you need a waterproof base.
Male oil is more fluid or a bit grainy at room temperature, like when you cook bacon in some vegetable oil and when it cools down, it goes partially solid. It becomes uniformly runny at body temperature.
The North American beaver can have similar differences, but less pronounced.

Tatiana what do you use the sac oil for?

just the usual. Catch more beaver.

Used some in combination with bto as the base for marten lure, worked fine.

I'm not really the right person to ask, I have no idea what I'm doing, I just play with stuff.

Tati, that's probably most of us on here. Just playin' with stuff.

For me it's just experimenting on a very small level.

My concoctions will all be 16 ounces or less. Most will be 4 or 8 ounce mixtures for my own use.

We can all buy what works, but it's interesting to make our own and have it work on the target critter.
