DIY Measuring Tools: Pencils and Rulers

image via Wikipedia

Carpenters use different types of pencils: hard lead, common lead,and the regular carpenter pencil. The most widely used type is the flat, hard lead pencil -- 8 inches long.  Utilised in rough work, the pencil should be trimmed so that only 1/4 to 3/8 inch of lead protrudes from the wood sheath. In finished work, the pencil must be trimmed so that 3/8 to 1/2 inch of lead is exposed and the lead tapered to a long, flat point. During marking, the pencil should be angled away from the guide so that the lead would mark near the edge of the guide. If the pencil gets wet, the glue that holds it together may fail and render the pencil useless.>>> READ MORE
