Blind Peg Marking

I marked the location of the pegs for securing/fitting the slab to the base yesterday. I have not drilled the mortises for the pegs yet. Because drill bits can vary slightly in size I need to test bit to peg to make sure of the fit. That is first thing this AM.

The blind pegging first step is to decide on peg location and drive a nail in far enough to be secure but easy to remove.


Next snip off the nail so it is lower than the slats used to support the slab while positioning but high enough to make a good mark and is also high enough to be easily removed.


Then position the slab. Once satisfied with position carefully remove the support slats and press, use a lumpy or whatever means needed to press the slab down on the cut nails, marking the position of the pegs and mortises.


The mark closest to the front edge of the slab will be drilled to peg size, single arrow. The back mark, with a circle, will be drilled elongated to allow movement of the slab. The marks on the base will be drilled to peg size and will have the pegs glued with around 25mm or so exposed.

An easy but ingenious process.

  1. I had been wondering how you might get the holes accurately lined up. Thanks for that.

    1. Matt,

      It's good to know the post cleared things up.

      I wish I could claim credit but it is a very old way of marking. BTW, I love how simple it is plus it takes away a ton of butt scratching.
