    Default Red Gum Table slab

    Hi Folks
    I am working on a VERY old Red Gum table slab and need some help. The table is about 5" thick and has a very large expansion crack in its centre. This crack goes right through to the other side.
    I have inlet bow tie wedges both sides as a decorative feature and I assume because of the slabs age and its extreme dryness that it is not ever likely to open up any more but some friends have told me because it is
    likely to be a food table that it may be best to fill in the crack. Now the problem - because of the size of the crack and past experience with casting resin I was contemplating filling the crack first with a putty or bog or the like
    and leaving it down from the top so that I can pour in the resin. Will this work? and has anyone any experience with this that can give me some advise.

    Depending on where the crack is in the table, perhaps consider a totally different timber as a feature perhaps?

    I'd be inclined to use casting resin, but only pour in a limited depth - say 25mm - at a time. First, clean it out thoroughly with acetone and a toothbrush. Build a dam of hot melt glue around it at the top so you can over-fill it and plane down. Underneath, close it off completely with some scrap ply or similar, also stuck to the board with hot-melt.

    I have filled cracks before and used epoxy. i haven't had much success with casting resin as I don't seem to get the rations quite right.

    I agree with what Alex has mention in the previous post and don't underestimate sealing the other side. The last thing you want is to be cleaning the floor.

    Put a few layers of masking tape on the back to contain the drips. Mix dried used coffee grounds with epoxy, it looks just like a gum pocket.

    To get the ratios correct for casting resin, get a graduated eyedropper and a large hypodermic (you don't need a needle). Then you can measure both resin & catalyst accurately.

    I have found that resin will usually find a way through tape when used underneath, what I have done is place plenty of tape underneath and then carefully pour melted wax in the gap avoiding the walls of the gap, this usually fills all the gaps, then pour in the resin.

    I use a piece of ice cream container taped tothe underside to stop the resin from running out. When measuring out resin Iuse digital scales to make it easier to work out how much catalyst that isneeded. Cheers WC
