TB3 for sinew.

[BowEd]

Bob...I know your on the right track.You make excellent bows yourself.Next time at Mo Jam you shoot one of my bows.I'll shoot yours too.I'll even take the chrono with me.Eric  makes excellent bows too.
Brad....your right.It just added physical weight to the bow is all and the bows parameters and profile stayed the same.
Mike....I've had the same experiences hunting with sinewed bows and sinewing 64" bows.Putting horn on the belly of 64" bows too long ago.It just makes them narrower and just as fast and faster than self bows.Arvin showed this.
This is tradecraftsmens' thread here and I see no need to post my accomplishments on it to hijack it.
Like I said earlier on a different thread there's lots of misinterpreted info spread on this forum.There's a tendency on this forum in that just because it takes more work it is'nt worth it.Wrong,wrong,wrong.Not if you know what your doing from trial and error.
Making bows to me is a continual learning process.I don't claim to know it all either.But what I do know I know.The adventure never ends if the desire is there.There are some outstanding bow makers on this forum.Not as many showing as years ago but there's still a few around.

Then their is  the fish bladder glue comparison with hide glue. Which is better, and why do you prefer one over the other?  Fact is TB3 works, fish bladder glue works, and hide glue works. From their it's your choice for what ever reason.

I think you should use egg yoke, have you ever tried to scrub that stuff off a pan?! 

[Parnell]

Wow, this evolved!  Funny, AllynT...that is a curious thought.

Does anyone know of any data driven work showing the result of TB and sinew curing into reflex, respectfully?

Cheers, guys.

TB and sinew take longer to dry than hide glue.   Hide glue and sinew will safely dry in about 10 days.

hide glue definitely cures much slower than TB3

hahaha.. love debating.. I stand firmly by my statement... at least in high humidity where I live.. I can not speak for drier climates... gut

What is your draw length and poundage Bownarra, that has the most to do with arrow speed and getting the most out of a bow.

I draw a paltry 25-26", 25" most of the time. I am sure the sinew enhanced the arrow speed for you, at my draw length, I don't know. I get in the low 160s out of my favorite static recurve at 52#, if I horse it back another inch to 27" and about 56+ pounds so I get 171, with 10gph. I really don't like chronographs, I think we all think to the positive on what a bow is spitting out. I have never shot a bow through one and come out with as high an arrow speed as I though I was getting, always kind of a letdown.

I don't know if it is the static recurve or I have gotten better as bowyer over the years but the my latest bows are better shooters than my former straight limb bows, more stable and forgiving and bit faster at the same poundage.

There was a foul mouth guy running me down on the Facebook stick bow page bragging about getting 195 out of his unbacked osage bows. He had never seen one of my bows or heard of me but immediately launched into a foul mouth tirade about how sorry I was and what a piss poor bow maker I must be all because I had give an honest appraisal of a bow someone had posted for sale that strung had one limb with a 6" brace height and the other with the string almost touching the very straight limb. The tillering job was the worst I have ever seen, the guy had sold similar bows and had this one up for sale for $450, people who didn't know better were going gaga over it.

I thought I was dealing with a 14 year old keyboard warrior because the language, spelling and viciousness of his attack. Then he posted a picture of himself drawing his bow, dang he was a monster of a man, at least 6'4" and a real knuckle dragger. So, he left that part out, anyone who is fortunate to have a very long draw length and the strength to pull a high poundage bow could match his arrow speed.

There were about 4 or 5 other guys that jumped into the fray to run me down as well, honesty really rubs some folk the wrong way. I took it for a day and asked the mods to remove me from their cesspool of a site, it was a breath of fresh air to come back to PA where the guys are civil, most of the time.......

That'll do it, I wonder what his arrows weigh and how long his bows last?

You should challenge them to a shoot off, most people are a lot less civil when they can hide behind their screen.

I forget who it was , but some body did a test with balsa wood. .He got no reflex with TB3, but did get reflex with the hide glue. In conclusion he stated that hide glue was the only way to go with sinew. I have used both. In my opinion hide glue is made for sinew, but I have sinew backed a couple dozen bows with TB3 that I was satisfied with. Ed Scott didn't like" messy hide glue" as he called it. For that reason he used TB 3.

Laubin discussed his take on the attributes of sinew and hide glue. His observation was that the shrinkage, pulled the bow into greater reflex, giving it the boost in performance. Dick Baugh did tests with sinew, comparing hide glue and Elmers for bonding. The results are what I would have expected. Little if any shrinkage with Elmers, and little to no advantage. In contrast, the sinew/hide glue shrank, pulling the bow into greater reflex, adding a boost in performance. I believe it’s your bow, and you can do with it what you wish. Just understand going in, the facts and what your expected outcome is. Having done a few sinew backed bows, I can say that it is a lot of work, at a minimum. I will at some point do another, despite the time involved, but my expectations might differ from yours. Have fun with it either way.

  Thick matrix versus single glueline.   

[Dances with squirrels]

I have one ready and waiting to sinew now. Sinew is shredded and ready. Just need to find the time. Soooo busy. I want to get it done fairly soon though, want to be hunting with it this October.

[Dances with squirrels]

It'll get hide glue for sure.... and the best pair of copperheads I have.

[gutpile]

PatM.. my reference is not to single glue line..in fact I size the bow with hide glue before I soak sinew in hide glue wring out sinew then lay on bow.. usually 2 full courses with a 3rd fill in to smooth out any spots.. to achieve the full benefits of all my labor (just processing the sinew is enough) I am going with the proven method of hide glue and sinew ( peas and carrots)..not some liquid hide glue from a  bottle either.. which if it dries in 10 days why does it continue to pull reflex for over a month into drying.. I also hang a weight from the handle to get even more benefits of my hard labor.I remove the weight after about 3 weeks or so.. and let set another month... not saying the TB won't work .. because it will work.. but you won't get the full affect of the sinew by using it.. you will get a strong back provided you've done the job right.. but you could of got more bang for your buck by slow curing the sinew job with hide glue.. down south especially.. gut

[PatM]

I was saying that Hide glue  matrix dries to a useable degree faster than a TB  one does.  Not saying it doesn't cure and dry more over time but it's still functional in about 10 days with good drying conditions.

 TB is slowed by its relative water resistance.

 My statement in error referred to you mentioning a TB  glued on skin dries quickly.
