The height of trestle for the average man is nearly 2'. The top should be made of 2"x6"x4', the legs of 1 1/8"x5" boards. The bottom of the legs may be tapered 1" narrower than the top. Set the legs in from the end 4". Notch in the side for the leg at an angle so the bottom of the legs will be spread 16" and out in line of the end of the top to brace, endwise. Nail a cross tie on the legs under the top of trestle. Set the trestle on a level floor, and compass and saw the bottom of the legs parallel to the floor. (Fig. 73.)
