I applied the sinew to this yew heartwood "bow" a week ago. I got that done and started working on another bow and looked up at my shop ceiling and thought, "Wow! what a great place to stash that sinewed bow." No doggy damage and outta my sight so I don't get after it too soon. The bonus is the heat run blowing directly over it. The humidity is 23-25% in my shop and will be for a few months yet. That will cure out sinew fast as anything.

Chris did you heat in the reflex or is it from reverse bracing?
-
Looks like serious reflex. Your shop must be taller than mine, I would be banging my head off that.
-
Awesome. Have fun getting that tillered! ;D
-
Yes Sir,
I'll be watching...

Is all that tension really on that arrow shaft, balanced on that bow?

Jon half is heated in and half is induced. It has about 6-7".

I have 9' ceilings Bob, I love that part about my shop.

It is Steve-O. I checked it last night and most of the string tension is gone already.

I kept her "straight" limbed for that reason TMK!

Very nice, PD. Good idea.

Coming along nicely, Pearlie. Great idea putting her up out of sight while the sinew/hide glue cures. I use the top on our hot water in the utility room for the same thing. I'm curious to see how much of the reflex remains after she's shot in.

Pat those are the billets hippy gave me last year at pappys. Not sure if you remember me showing you? Very, very old billets with micro rings and it appears the sapwood was "chainsawed" off, not by hippy of course.
-
I do remember them. The old yew heartwood should really shine with the sinew backing.
how long is the bow?
-
Chris,
Cool idea with the tillering boot and arrow for reverse...Will definitely cure better up there...

63" now, about 1 3/8-1/2 wide. Never measured it.
-
Just make sure you don't trigger that "set bow" and shoot yourself in the head. ;)
-
Not much tension left PatM! If I let it go the tips might settle 1-2" max.
-
Great idea. :)
-
Yep, some low humidity and air-flow is the way to go. That is going to be a sweet bow. Looking forward to it.

Well, I guess it might've had a chance at being something good, IF it had been crafted from a peice of Osage instead of that silly pink stuff. ;) :P >:D

you are in a hurry?
sorry, but not convinced that speed drying is the best method. Perhaps you should turn around the bow 180° from time to time.
But, ...
... the bow looks good!!! Good Luck!

Simon Im not speed drying the sinew. I just know its going to dry very fast due to very low humidity in my shop, 23-25% is bone dry. It will still sit idle for 2 months and Ill tiller it out then. I reach up and spin the bow every day so its getting equal air flow.
-
I don't have any heat in the garage, but when my wife parks the car nightly. it creates big time heat. I have 2 cieling hooks near the front of the car. I have pieces of what have you like choke cherry, and ocean spray on those hooks. It drys in half the time
-
My sinew backed osage bow has set in less than 20% humidity for three weeks with some air flow around it. I tillered her out and have shot her 100 times, lost maybe 1" of reflex.
It seamed very dry. did I not let it cure long enough??? Can I expect issues with tiller due to drying sinew? I have never seen in my research a good answer to this question.

I can only give my theory Bassmaster Bill. Take from it what you wish. I hear the word "cure" a lot regarding sinew. This sinew was 2 years old and stored open air. Isnt it already cured? Im thinking dry glue is more important. If you weigh it after 2-3 weeks and again every day for a week after that and its doesn't move. Id say its as good as it going to get. Ive never had a tiller change on any sinewed bow Ive done. Ive never had the hide glue crack and make any noises, Ive never had it separate and Ive never gained or lost any very noticeable weight. Maybe Im lucky, or maybe my sinew was "cured" just right. Lord knows.
-
Well I understand everything your saying Pearl, but the only thing you have said that is definite is weighing the bow. and as you said if the sinew is dry and cured when you start, then it just the glue moisture that needs to be removed. This is some good food for thought, but I think my bow was dry and ready to work. I will keep an eye on it and report any issue/changes that come up. With this being my first sinewed bow I'm really taking notes.
Good post, Thanks to everyone for posting info it's really interesting.
