2. Terms • Tools-any instrument used in doing work • Hand tool- any tool operated by hand to do work • Power tool- operated by some source of power other than human power

3. Advantages of Using Hand Tools • Effective & efficient • Use hand tools when electrical or engine power is not available • Used for small jobs, where large machines can’t function

4. Selecting Hand Tools • Select quality tools • Brand names=better quality tools • Using wrong tool can be dangerous, can damage the tool, and result in inferior work

5. Layout Tools • Tool used to measure or mark wood, metal, and other materials.

6. Tape Measurer • Come in lengths ranging from 6 foot to 30 foot, a width of ½ to 1 inch, • Can lock open, and use a spring to retract the tape with the push of a button.

7. Combination Square • Determining 45 and 90 degree angles

8. Framing Square • Squaring cut corners and laying out stairs and rafters

9. Try Square • 90 degree squaring

10. Framing Square • Squaring cut corners and laying out stairs and rafters

11. Level • Leveling and plumbing

12. Other Measuring Layout Tools • Electronic Tape Measure • Divider- • Marking Gauge • Chalk Line

13. Once materials are measured and marked, they need to be cut, shaped, and bored as needed to prepare for assembling

14. Saws • Classified by use and teeth per inch. • An 8-point saw would have 8 teeth per inch. • Handsaws include the: • Crosscut, rip, compass or keyhole, coping and backsaw.

15. Coping Saw • Cutting curves and irregular cuts in thin materials

16. Hack Saw • Used for sawing metal

17. Shaping Tools • Includes planes, wood chisel, and rasps.

18. Plane • Tool used to smooth surfaces and change the size or shape of wood materials. • Planes include: • Jack Plane • Smoothing Plane • Block Plane

19. Jack Plane • Usually 14 inches long • Used for smoothing long surfaces by shaving with the grain of the wood

20. Smoothing Plane • Usually 8 inches long, • Used with the grain and to finish smoothing

21. Block Plane • Usually 6 to 6½ inches long • Used for smoothing the ends of boards by cutting across the grain. • To avoid splitting corners, clamp a piece of wood on both edges of the board or plane from the edge toward the center.

22. Wood Chisel • Wedge-shaped cutting tool used to cut notches and shaving off excess wood • Come in a variety of widths and are generally hit with a wooden mallet.

23. Wood Chisel • Keep the chisel sharp for safe and effective use. • To mark a slot turn the bevel of the chisel inward and up to cut shallow, and down to cut deep.

24. Wood Rasp • Also known as a wood file • Used for smoothing rough work and for removing small amounts of wood on curved and irregular-shaped objects.

25. Wood Rasp • Be sure the rasp has a handle. • Apply pressure on the forward stroke. • Clean the rasp with a wire brush or file card.

26. Boring Tools Includes the • hand drill • push drill • brace and bit

27. Hand Drill • Device with gears that drive its bit much faster than the handle turns • It is used for small holes when it is not convenient to use an electric drill

28. Brace • Device for holding and turning an auger bit

29. Auger Bit • Square tang to fit into the brace. • The cutting end has a feed screw, cutting lips, and cutting spurs

30. Auger Bit • Drill until the feed screw begins to come through the wood, then back out the bit, and turn the wood over to finish the hole from the other side • Prevents the wood from splintering out

31. Holding or Gripping Tools • Help complete the job quicker, easier, and safer • Clamps and vises • Used to hold or grip wood or metal while being cut, shaped, bored, and fastened • Pliers, wrenches, and screwdrivers • Used at times for holding, gripping, or turning.

32. C-Clamps • Clamping two or more pieces of metal together • Named after It’s C Shape

33. Bar Clamps • Adjustable clamp that can range from a few inches to six feet

34. Hand Screw Clamp • Clamping wood together • Can span up to 10 inches • Requires two hands for tightening
