I caught some beaver earlier this season, got them skinned, and froze the carcasses. I brought one in to taint, hanging it in the garage, bagged. I noticed the blood was dripping to the bottom of the bag, so I caught it in a bottle. I had some glycerin I added, but it was not enough to keep it from freezing. I can go buy more, but am thinking I'd like the final product to be a bit thinner so I can apply it through a squeeze bottle.
I've done some reading, but am wondering what you might use to keep a lure from freezing, and in this case, make it a bit thinner. Things that have been mentioned on numerous trapping sites: propylene glycol (not ethylene/automotive), 100 proof vodka, everclear, and mineral oil. I think that pretty much anything I add is going to have some smell. The blood itself is pretty powerful after being in a bag hanging w/ the beaver for a week. By the way, the alcohol products were mentioned as helping to stabilize the lure and keep it fro molding. Any truth to that?
I've also got some other lure that has been "baking" for over a year. I'm ok w/ making that into a paste with glycerin. At one point, without any additives, it acted more like sherbet when cold, but I'd like it to be able to spread and stick better.
I did find some pints of glycerin in FAI, but so far no gallons. At almost $10/pint that is about $80/gallon. Way too much for my blood, especially when on line gallons list for about $24. Anybody in FAI have any squirreled away for a rainy day?
Yes, castors and oil glands have been removed for other uses.
