Glue for splice joints

[stringstretcher]

When making and glueing splice joints in laminations like this, what would be the best glue to use to make sure they don't seperate?

Do you have any urac Charles? Is that a test strip for your boo backing? If so, then urac is the way to go.......Art

It will be for hickory, bamboo flooring, and osage.  I have long enough strips of bamboo to make a full length backing, but the hickory I got and cut, bowed so bad, I can not get the width out of the full 72" pieces I need.  But cutting them into 36" pieces, I and cut the bow out and it still leaves me enough for the width.  If that makes any sense.....

I was looking for a glue, that I can splice them, and make them hold through out the urac glue up process.  I know I will have to put a piece over the front of the bow over the splice, as I just found out the hard way, it will not hold....don't ask how I know....lol

Urac is the way to go but I would only use the splice in a non bending handle.

Is there a better splice for a bending handle??? Most all my wood is short, 36"-40".  So I have to find a way to splice them to make full length 72" laminations to glue up.  Any help and suggestions would be greatly appreciated.

As I am not building a bow designed as a bending handle, but rather a 12" long, 1 1/2 wide and 4" thick glued onto the belly of the bow for a handle, maybe a different kind of splice would work better??????????

Can you splice your center lam only and use full length to sandwich? If the lams were thicker you could pin them with chop stix to be sure they dont come apart.

That's my problem Pearl.  I have no wood that is long enough to make full length backing or lams of one piece wood.  I have nothing over 40" long to work with to make my lams, backing, and belly.
That's my problem.

Overlays would do the sandwich job then. Your handle on the back and overlays on the front. URAC done right doesnt let go..........ever.

What length bow do you have in mind Charle? With 36" length materials you can make a 65" bow. Maybe you're approching this the wrong way by using shorter stock.

Try making up two 36" billets and use a regular 4" splice. Study these billets from another thread that I roughed out.

Just add a handle/rise piece to a pre-glued up lam. Once you have the billeted lams together, riser shaped, then add your belly lam.....Art

Thanks Art.  Yeah I have billets drying to make me a couple of self bows with and I will definately do those your way.  The spliceing on the lams is for an all laminated bow.  Hickory backing, and osage and or bamboo flooring core lams and or belly lams.  I want to make at the longest a 66" bow (laminated) using 4 lams of a minimum thickes of 1/8 thick to make it 1/2 inch thick at the fades.  And all of the wood that I have to make these laminations is the pieces that are 40" long, that came from a saw mill. I can not get a self (billet stave) out of this lumber.  So I am looking for my best option spliceing them in the middle of the handle.  Thats the only place I can put the splice.  Hope this makes sense.

I was talking about making your lams/limbs up in billet form Charles. Then add a riser piece (would look similar to my wood billets) to each billet. Belly lam would then run up the riser once the lam billets was glued together. You would still have a laminated bow, but spliced together in the handle. You would need to cover the splice witha nice leather grip or something similar.

You can do a reflex/deflex/straight or whatever you want at splice glue-up. Reflex could be added (if so desired) to the limbs when you glue the backing and other two lams up......Art

I got you.  That just might be my answer.
