Tonguing and Grooving: Double Job, One Plane


The Tonguing and Grooving was a common way of joining boards; in fact we can find many tools dedicated to this job. Is the case of this "combination" plane coming from UK.

 It's marked "MOORE LIVERPOOL", Planemaker  working between 1824 and 1870. It has the feature of having two blades, one for the tongue and another for cutting the groove, just turning the plane in the opposite direction. The fence is in the middle of plane body; in this way the cut will be always to the same distance from edge. This plane cuts in the center on 3/4" thick boards, but others were for different thickness. 

The plane needed some care, mainly in the mouth area where I preferred to close a little bit the opening, restoring the correct geometries. Moreover I had to substitute one wedge for which I used a cherry scrap. After the blades have been sharpened, the plane restarted to produce shavings with a good precision, unexpected for a such old tool.

  1. It's wonderful to restore these old wooden planes to work again.

    What wood did you use for the mouth repair - beech?

    An excellent result with the joint!

    1. Hi Rob,
      This plane is at least 150 years old. I used beech for repair it, the same its wood. I think it's a clever design and I cannot understand why it's less common as the wooden tonguing and grooving matched pair planes.
