When the wood is reduced to a level surface, mark the surface 

 so produced, and plane one edge to an exact right angle with 

 this surface. These are the standard "face and edge" from 

 which all others are " squared " and marked. 



Plane to thickness by scribing a mark round the whole piece 

 with the marking gauge, set to the minimum thickness of the 

 wood the planed surface pressing against the stock of the gauge. 

 Remove surplus wood indicated in this manner, and plane smooth 

 with finely set smoothing plane. 



By means of a trysquare squared to true "edge," mark the 

 two ends of the wood at right angles to the true edge, and saw 



along these with the tenon saw. 

 (Note. A bench hook (Fig. 7) is a 

 great convenience here.) The saw 

 should not be put on the line, but 

 outside it, and the line should be 

 drawn by a chisel, not a pencil ; 

 the cut will then present a clean 

 edge instead of being frayed by the 

 action of the saw.

The wood may now be marked out, in the shape shown in 

 Fig. 8, leaving a tongue 4" wide in the middle. The corners are
