1. Hi Paul …very interesting thank you

    My question is glue you used, it looks like resin W, a water soluble glue.

    I guess you are using oak? I have learned water on oak can turn parts of the grain black?

    I recently picked up a superb plank of 20mm mature oak 15″X 72″ from a skip (yes I did ask the owner). I made this into a shelf but needed the front edge to be 40 mm….so I cut and glued a 11/2″ strip to one side. My problem is:- a DARK GREY LINE when planned…….I prepared both mating faces and used about 10 clamps??………am I asking too much….please help

    Thank you John 2V

    1. Well, tannic acid (occurring naturally on oak and many woods) reacts with some glues but not usually PVA which is the glue I commonly use. Some glues like animal hide glue can be less refined and retain darkness in the glue line but again I rarely use animal hide glues these days except for instrument making in bowed instruments. PVA does not show a glue line but if steel screws are near to the surface or you use steel clamps they will turn the surrounding area in contact with both glue, steel and wood black or dark brown.

      1. Thank you Paul…to clarify I use evo-stick resin W it says it is suitable for the oak I have used……quite possibly its when I wipe with a damp rag causes the black to wavy grain of oak NOT smooth part of grain. I use clamps like yours NEVER metal clamps without a protective face.
        I made some little boxes with resin W and wiped off with damp rag…result black stain………I showed this to you Paul at the book signing.

        In the future I shall be extremely careful to avoid “squeeze out” of excess glue.

        Thank you for taking the time in your busy work load….just watched the chat answers….really enjoyed……..thank you John

  2. Cornflowers, not sure about which glue you used. In my experience, moist contact with ferrous metals reacts with the tannins in oak to cause a very dark stain. If you apply a coat of lye to oak, you can get a nice brown (fumed oak- this was an old technique to use lye fumes to pigment).
    Maybe a chemist can add more info here about your glue?

    1. Often our willingness to engage in answers can lead us into uncharted waters. Chemicals like lye and ammonia, though commonplace as household cleaners, are mostly sold in supermarkets in diluted household form. In most cases they can be only a fraction of a more pure and undiluted form so that they may well be safer, but they are still dangerous and harmful chemicals so in the wrong combination with other substances and materials they can create conditions we don’t want. Pure lye on wood containing tannic acid creates a reaction resulting in eruptions of white or coloured powder and this must usually be neutralised to make the surface accept a finish again otherwise it not take a finish and can and will cause the finish you apply to peel away. I say this because chemicals must be handled cautiously.

    1. I enjoy learning from all, and what Mr. Engel taught me best, is how to bend wood. Heat, not water, not steam, but HEAT gives us the ability to bend wood into the shape we need. And spare pieces–because some bends fail. Cheers.

  3. DANG, I’m still not “up” on the exact method to be used on this table to join the top to the frame.

    Of course I see the mortises, but didn’t catch any discussion of how they are to be employed. And I cannot find any one anywhere using Paul’s technique-short of going to an antiques store and trying to “get lucky” finding a similar piece.

    I get all the other aspects, learned all of them making my Bench and watching Paul’s other videos and being a “member” for some time here. Oh well, I’ll wait until the release #8. Paul works REALLY FAST in 1.5x!

    1. There are other video’s of Paul using this technique. Either on this site, or on youtube. But after the mortises are cut, you make a small “button” out of wood. It ends up being roughly in the shape of a letter “z”. You screw the button on the the table top, and the other end of the “Z” slides in to the mortise. It locks the top on, while allowing the top to move with seasons.

    1. Appears to be of a Stanley No. 80 variety – although unclear specifically but Paul has created videos on this type and its sister type the Stanley No.81 at different times – available on YouTube as well as here probably.

  4. Hello,
    I’ve made 2 tables and both of them, before adding the clamp where square. I manage to destroy both of them, after I use clamps, Any tips how to tackle the pressure, or how to arrange them so I dont have an out of square table?

    1. Hi Claudiu,

      Paul says:
      It’s very difficult to explain and would take several paragraphs but basically you apply the clamp pressure by having the clamps out of parallel to the frame so that the pressure pushes the long point to a shorter point. That is the internal corner where the distance is longer, your clamps will need adjusting. It sounds complicated but just experimenting you can see which way out of square it is and make the adjustment accordingly.

      Kind Regards,
