2 OBJECTIVES 1.) Identify the key terms for the unit. 2.) Identify common hand and power tools used in agricultural mechanics. 3.) Select hand tools needed for a particular job. 4.) Determine the cost of acquiring each tool.

3 TERMS  Blade Balance- a device used to balance a lawn mower blade to prevent excess vibration during operation.  Board Foot- Circular Saw- a motor- driven power hand saw with round blade.  Circular Saw- a motor- driven power hand saw with round blade.  Common Nail- A kind of nail with a flat head that is used in general construction.  Concave Bevel- a bevel, which is hollowed or curved inward.  Convex Bevel- A bevel which is raised or curved outward  Crosscut- to cut across the grain of wood  Crosscut Hand Saw- A saw with small teeth (more teeth per inch) for cutting across the grain of wood.  Dado- A square or rectangular groove in the face of the board

4 TERMS  Double Inclined Plane- A plane made by two bevels creating a point similar to that of an axe  Finishing Nail- A slender nail with a small head used for interior trim work  High Speed Drill- Twist drill made tempered specially to drill holes in steel  Hollow Ground- A single inclined plane which is concave ground  Hone- the process of finely sharpening a cutting edge with a bench stone or hand stone  Kerf- Opening in board made by the cutting of a saw blade; also referred to as saw kerf  Kickback- A safety hazard that results when a saw blade binds in the material being cut resulting in uncontrollable throwing of the material or saw  Rabbet- A cut or groove at the end of a board made to receive another board and form a joint

5 TERMS  Rip- To cut along the grain of wood  Rip Hand Saw- A saw with larger teeth (fewer teeth per inch) for cutting with the grain of wood  Revolutions Per Minute (RPM)- the number of times a rotating shaft or blade turns or rotates in sixty (60) seconds  Single Incline Plane- A type of bevel with one edge; used on wood chisels and plane irons  Twist Drill- Common drill bit used for making round holes in wood and metal

6 Carpenter Hammer  Used to drive or pull nails  Can have either a curved or straight claw HAMMERS ($5-$60)

7 Machinist Hammer  Used to work with metal or around machinery  Distiguished by a variable- shaped peen  Ball peen hammers are made in different weights usually 4,6,8, and 12 ounces and 1, 1 ½, and 2 pounds. HAMMERS
