Preparing horse sinew for drying

[jameswoodmot]

Thought I’d put this one here as it might get more views

After my recent foray into sinewing I realised I want more sinew, but am not a hunter and do t know any.

But I am a farrier, so I phoned the knacker man (what animal euthanasia man is called in England) and asked for some legs. We used to get them from him for dissections as apprentices and for competition practice.

I’ve seen reference to horse sinew being used but can’t find anything online.

They’ve got a lot of membrane attached, I’ve “fleshed” as much as I can but the damn things are slippery as hell and the membrane is patchy and won’t come off in a nice sheet. How much of this needs to come off before drying and will be be a problem either for storage or for later processing?

Anyone dealt with horse tendons before or used them on bows?

I’ll put pics in comments below

Longest are 16” or so

You can see how much membrane is on them. Maybe I’m better off freezing them then drying as I need them?

Ya my moose tendons looked similar.  I would not go crazy cause you will just pound them anyway when dry.  The casing will come off fine.  Mine were not bad with the moose leg tendon.  Get as much off as you can and then dry them.  You will pound them them wash and degrease them anyway.   Get as much of the fat off now as you can.   Good score.

If you can get it from your man, the most prized sinew was the paddywhack tendon - the neck/spine tendon

Yep, just let them dry then pound them, comb them, all the crap will come off. Never used horse, don't see why that wouldn't be good. I think Chinese bowyers used horse, so it should be good.

I used cow leg tendons before but found that they were fatty and needed to be washed and de-greased.

I also harvested the neck tendon from cows and found they were not usable, they are a different type of tendon and don't have any fibers.

Yeah I’ve heard about beef sinew being oily. I tried some I bought as dog chews but they were rancid, apparently the dogs prefer them that way!

I got these legs under the guise of using them for dissections, which in fairness I did do, but I don’t know the guy well enough to want to explain what I want them for. I definitely don’t know him well enough to ask if I can basically butcher someone’s dead pet to get to the back strap or neck sinew!

Interesting what you say there Mark. Looking online the paddywack is a ligament, not tendon, which might explain the difference. In horses they have what’s called the suspension ligament, which is a long tendon like ligament that allows the horse to stand without muscular effort (so they can sleep standing up). In some foals there are muscle fibre present in it, it seems to be a muscle that has disappeared and been replaced by just collagen fibres but it’s not got the same structure as either tendon or ligament. I’ve saved them and will see what they’re like.

In the photo from left to right are the two flexor tendons (back of leg) the two extensions tendons that are fused (front of leg) and the suspensory ligament on the right.

There is also another long ligament which i saved from one leg that is a bone to bone ligament and still nearly the size of a roe deer tendon

Thanks for the help guys, got them in the kiln drying at 30c at the moment. Looking forward to pounding one up!
