Glueing Stabil-Kore.

[Buemaker]

How do you treat Stabil-Kore before glueing it in a bow limb?
I had a set of limbs with this and for a couple of reasons I did not trust them. Could be I was too cautious, but I plyed the lams apart and stripped them apart.It would most likely have been okay, but I thought the SK did not stick to the wood lams as good as it should.
Before glueing I degreased the SK with acetone and sanded it and made sure all dust was gone.

I just used a Hard brush and glued it in the stack next to the belly glass, Awesome stuff.

Clean it with acetone. being its woven give it plenty of time to dry. Also because its woven dont spare the glue. I butter mine and let it set if it looks like it soaked in I put more glue on it.

Lightly sand wipe with acetone.  I put it as close to thg he belly as I can.  Not sure if that makes a difference or not.  No problems with it at all.

I clean with acetone and butter it up heavily and lay it up.

clean with acetone and glue.. Never have an issue.

You would be surprised how easy it is to peal a bow apart!

The peel apart part is scary. The first time I had one I am thinking WTH.
Anyhow the reason I said dont spare the glue is I put it under clear trying to get a cool look. and there was a few tiny spots that needed more glue. Being most put it under veneer or core you would not notice. BTW it wasnt that cool lookiing

Just used some for the first time. It really soaks up the glue well. Turns a nice dark color so you can visually see where you got it on. A quick wipe with denatured alcohol is what I did. It felt like it had a good rough texture so I didnt sand.

Has anyone tried two layers of the stuff, say in a skinny recurve limb?  I could actually see putting a layer under each veneer to stiffen things up.

Curious about this topic. What’s the reasoning behind putting it closer to the belly glass ?

[jess stuart]

I think someone once told me closer to belly was better.  I guess kind of like putting the thicker glass on the belly when using two different thicknesses.  I have put stabilcore mid stack and couldn't see any real difference.

Stic, might have been the dreaded acetone gas!! 

[Crooked Stic]

Naw let it dry plenty long to get all the acetone out 

[BigJim]

It should work better the closer you put it toward the back. Thickness advantages on the belly are due to increased compression strength, not torsional. The stabilcore is basically only there for torsional strength. It may have some advantages close to the belly.

Imagine taking the hook of a curve in your hand and twisting it around it's center.. when the stabilcore is near the back, it will resist the twist the most. Inwards near the center of the stack, it will be rolling around it's axis. Now, it shouldn't be completely neutral in any position, but more likely that you won't reap the most benefit away from the back.

Food for thought for sure.

I agree with Jim, I have done it both ways and in my bows I get better results closer to the back I can get.
I’ve done 2 identical layups with one on the belly and one on the back. The one with it on the back had noticeably more torsional stability.

Are you putting it up next to the glass on the back? I only have 2 lams in my recurves and was planning on putting it in the middle of the two.

With colored glass you can go right next to the glass, with clear glass and veneers you go under the veneer.
