Post subject:  CA for laminating bindings
I am laying up amazon rosewood bindings with .030 maple and was thinking ca might be a better choice to avoid heat delamination during bending and was wondering if anyone uses ca for this purpose???? :?: :?: :?:

I have used CA to laminate binding and purfling on several occasions and the subsequent bends went just fine. No delams yet.

Maybe you guys have better CA...

I do a lot of bending around Venetian cutaways and CA won't hold doing that and is a pain to re-glue. I use LMII white, which mostly holds and if it lets go a spring clamp immediately applied will stick it back down. CA won't allow that. If you stick on multi-lam purfling, it is often the glue in the purfling that will give out before the purf-to-binding joint.

Nothing wrong with it as long as it's working for you. Another option to consider that I like, and a lot of the big manufacturers use, is titebond melamine glue. It dries clear and colorless, plus it is plasticized to within an inch of its life making it extremely pliable. As a result the binding will have much more "give" to it in the first place and will require less work to bend. It's a really nice tool to have in your arsenal of adhesives. While I don't doubt the job can be accomplished with CA, but it's definitely uglier to work with and much more expensive than PVA. Out of curiosity, how are those of you who use CA going about the lamination process? Are you feeding it through a pinch roller as you go?

what temperature does ca start debonding??????

The nice thing about CA is that you can get your pieces all lined up and clamped and the wick the CA in at your leisure using a micro pipette. At least that's how I've done it.

Does the titebond melamine withstand heat pretty well?

Where do you get titebond melamine?

just pulled the bindings off of the bender , pretty tight venetian bend , no problems... bliss

No, the heat resistance for melamine glue is actually quite low but since there's not much mass in the bindings it will cool down rapidly and return to full strength in the process. I haven't seen much data on the exact melting point of CA, aside from the fact that it forms chains of acrylic. With that being said it's likely a few hundred degrees F. My bigger concern stems from the fact that CAs are intrinsically brittle, will soak into every available pore, and result in an end product that will require much more effort to bend than it likely needs to be.

It's a specialty product, so Woodcraft/Rockler probably both carry it.
