    What glue are you using to laminate your hardwoods together?

    Hi we use both Gorrilla Glue and a glue that is made here in my home town of Sheffield UK goes by the trade name of jurasic glue.

    In order of bond strength - Good> Stronger> Insanely strong.<br><br>Wood to Wood ... <br><br><strong>Titebond 3</strong> (only if used properly...no gap filling properties...careful clamp pressure to avoid starving the glue joint)<br><strong><br>Gorilla</strong> (only if used properly...some gap filling properties...careful clamp pressure to avoid starving the glue joint)<br><br><strong>Urac 185</strong> (urea formaldahyde glue...short shelf life, needs to be mixed, dry times differ with temperature, very VERY strong glue). <a href="http://www.3riversarchery.com/Bow+Building+Glue+%26+Adhesives++Urac+185_c49_s199_p0_i4430_product.html" class="postlink" target="_blank" rel="nofollow">link</a><br><hr>
    <br><br>In order of bond strength - Strong> Insanely strong when fully cured.<br><br>Wood to Wood, Wood to Fiberglass/Carbon ... these need to be cured (polymerized) in a hot box(aka "glue oven") for a specific amount of time at a specific temperature...but the bond is insane.

    By "starving the glue joint' do you mean if it's too tight there's not enough glue left in the joint to bond? I just so happen to have some gorilla glue. <br>

    Yep, it's like taking two pieces of glass and putting a few drops of water in between. Then place this sandwich on the table and press on it...you will see water squeeze out, once you let go - air will get sucked in....this inner tension is also present with glues only they cure and no air gets sucked in, but the stress remains locked into the joint which weakens it.<br><br><font color="blue"><strong>Ivo</strong></font>

    I use "UHU sofortfest", as it hardens in two minutes and I am an impatient guy.<br><br>Holds real well, and it nicely fills gaps, especially when mixed with sawdust.<br><br>It is a two component epoxy glue, of course.<br><br><a href="http://www.amazon.de/UHU-Zweikomponentenkleber-Plus-sofortfest-35g/dp/B000KJO9FS/ref=sr_1_4?ie=UTF8&qid=1317965577&sr=8-4" class="postlink" target="_blank" rel="nofollow">Here it is on Amazon Germany</a>

    Yellow <img src="http://illiweb.com/fa/i/smiles/icon_smile.gif" alt="Smile" longdesc="2"><br><br>If you want to go cheap (where is a lot of gluing) but decent I suggest to try two compound<br>polyester resin like those used in car shops for patching the cracked bumpers<br>with fiberglass. I have made wood and different fabric laminates with it and it<br>holds real good. It feels gaps really well and polishes better than epoxy.<br>Cheers<br>Rafal

    I also like Gorilla glue. There is also a quick set Epoxy with the twisted plastic tube that mixes itself on the way to the project( love that feature!). It's made by either Titebond or Locktite-excellent stuff. The Gorilla glue has some voids when she's all dry-kind of like a sponge. I fill the bigger voids with wood putty,sand and seal and no one is the wiser- except of course some very intelligent wood workers like yourselves who would know!

    I concur, I like Titebond, Gorilla, urea formaldehyde (Resorcinol) and 2-part epoxy. <br><br>I have found that for side grain joints (parallel grain) the Titebond is stronger than the Gorilla but on an end grain joint (end grain to end grain) the Gorilla is way stronger. I'm sure that is the type of joint they use in their advertisement.<br>I think that the end grain joint soaks up and starves the Titebond but the Gorillas expanding action fills the end grains. <br><br>I haven't had to use any glue on a slingshot frame yet but I've used them all on various knife handles, bow staves, gun stocks, guitar bodys, drum bodys, furniture and cabinets. If I'm gonna glue up something that I think is really critical I'll mock up several experimental joints and glue'em up with different glues and give them the test to destructive failure. Who doesn't like destruction? Really dense woods are the trickiest . I think some woods, like ebony, rose or bubinga, have lots of fat/oils in them. Sometimes it can help if you degrease the surface of fatty woods with a strong solvent. Resircinol UF seems to absorb the fat/oil with no problem. Good luck.

    i always have used yellow wood glue or regular carpenters glue. I never knew that so many people used gorilla glue for wood working, i have lots of it and iv never used it for bonding wood, i dont like it too much because it foams up allot.

    I use carpernters woodglue too. if it is used in the right way you get absolute solid adhesion. expensive super glues are not required when you glue wood on wood. <br>I bought some woodglue some weeks ago and i got a 10kg bucket high quality stuff with hardener for about 50 &euro;! <br><br>For wood on metal i take epoxy glue. the same as jörg posted... <br><br>
