    Default What glue is this guy using ?

    In this video

    https://youtu.be/cisxRjsm0Kc

    At about the 11 mins 15 seconds mark, the cabinetmaker uses a glue that I don’t recognise.

    He appears to be using it to glue timber drawer fronts to timber drawer carcasses.

    He puts it on in a squiggly pattern - and it looks like yellow pva. The quantity appears a bit light for pva but not much. He doesn’t appear to spread it out. Then he puts a drop of clear liquid every few inches - which I guess is hardener.

    Then he assembles the items and appears to get an immediate bond.

    So what is it ? Is it some sort of magical mix of pva and cyanicrylate, relying on the ca for the immediate bond but the pva for long term hold perhaps? Or is it a woodworking cyanacrylate with lots of filler ?

    Anyone know

    Cheers

    The PVA is Titebond original. You can see the top of the bottle at the top of the screen (bottle is upside down). The clear would just be CA for the instant bond.

    It's a common technique, the yellow glue is PVA and the clear is cyanoacrylate which grabs in seconds and acts as a clamp to hold the pieces together while the PVA dries.

    What they said.

    I've used it in model making for laying hull planking that has to follow compound curves but never thought to use it on something quite that large. I would suggest the CA is of the slow setting type often used by penmakers because the cellulose in timber kicks off the curing process of normal CA alarmingly quickly.

    One thing the cabinet maker doesn't need to worry about though is having somewhere to hold the timbers while the CA grabs; I found that holding 1/4" wide walnut strips hard up against a ships framing by finger pressure alone often then required a scalpel afterwards to remove said finger from model!
    Nothing succeeds like a budgie without a beak.

    Ok, thanks.

    I had heard of people using both CA and PVA (etc) simultaneously, but I thought an attempt would be made to keep them separate spatially. In this case he appears to deliberately put the CA where the largest blobs of PVA are occurring. Is it normal to allow the pva and the ca to mix together ?

    Doesn’t mixing weaken the bond of one or other glue?

    The CA glue is usually triggered by moisture in the air or in the wood, so mixing it with PVA results in a much faster bond.
