    G&G Square Holes

    There are a lot of pegs in the night stands I'm working on. I had to stop and touch up the motise chisel so I took a few shots.

    A couple cones and a diamond plate touch up the chisel in just a few moments:

    Clean out with a 1/4" chisel to about 1/4" deep:

    1/4" dowel goes through the tenon. 5/16" ebony plug goes in the square hole.

    Yeah, works pretty neat, huh?

    I have an old TaiChi 3/8" square chisel that I keep for just that purpose. The drill bit for it broke a long time ago, and just kept the chisel. That way, I don't batter up a 'good' mortising set when setting those square plugs.

    Mortising

    Hey Jim,
    When I make my mortises I take a very sharp knife or chisel and cut around the area where the hole is going to be. I never thought of using a mortising chisel like this. Looks like this method would work better. What do you think? Thanks, Joe

    I've done it 'your way' many times, and it certainly works - it's also most likely the way that G&G did it originally, too.

    The square chisel kinda takes the guesswork out of the process, though. It ensures that the mortise will be square, and not a parallelogram.

    Even after tapping out the form with the square chisel, you still need a 'regular' mortising chisel to finish the job. The square chisel is really just a layout tool.

    Quite correct. It is a cheap-o. A $10 Grizzly if I remember right. I just need all the help I can get . The pegs are still done oversize with a taper so really any irregularites get dealt with through tapping them in. This just helps me keep from having them twist CW or CCW whilst tapping away .

    This is the way I've done it as well - works great!
