the plane set to take a light shaving, proceed to surface the 

 stock, as explained in Sec. 28. The planed surface should be 

 tested with the blade of a try-square or other straight-edge, 

 placed in several positions. When testing, place the blade of 

 the try-square across the surface at different points. The 

 amount of light shown between the board and the try-square 

 blade will indicate the low places in the surface. Continue 

 planing either by taking regular shavings across the board or 

 by planing high places only until the straight-edge test shows 

 approximately the same amount of light for all positions of 

 the try-square. Mark this surface 1. 



30. Joint Edge. Place the board in the vise with one 



edge up. Plane this edge until 

 it tests straight lengthwise by 

 the straight-edge test, and 

 straight and at right angles 

 with the face surface by using 

 the try -square, as shown in 

 Fig. 61. The try-square should 

 be placed on the edge at 

 several points, always having

31. Second Edge. Set the marking gage and gage for 

 width of the board, using the method described in Sec. 13. 



Plane the second edge of the board as you did the joint 

 edge. Test frequently with the try-square, and keep the 

 amount of wood to be planed off the same in thickness the en- 

 tire length of the board. Remember, when the gage line is
