For satisfactory fuselage checking and truing let us say in the field shop, a certain minimum equipment of tools is necessary. This equipment is:
At least two sawhorses about 3 to 4 ft. high for mounting the fuselage in flying position.
Several wooden wedges (show taper) for easy adjustment of fuselage for cross and lengthwise level.
About 25 yd. of strong linen line for checking center lines.
2 carpenter levels about 2 to 3 ft. long.
4 perfectly formed steel cubes about 1¼ to 1½ in. in size.
1 plumb bob.
1 small screw jack.
1 pair of wood clamps.
1 straight edge about 12 ft. long.
