Figure

Tools, measuring and testing means

Bit brace, auger bits of various diameter, marking gauge, folding rule or measuring tape, try square, awl

Auxiliary accessories

Carpenter's bench, scriber or pencil

Necessary previous knowledge

Measuring and scribing, units of measurement, properties of wood

Explanations to the working drawing

Front view and top view of the workpiece, scale 1 : 2.5

Sequence of operations	Comments
1. Prepare the working place.	Check the boring tools.
2. Clamp the workpiece.	Make sure that it is in horizontal position.
3. Scribe the centre line by means of the marking gauge.
4. Determine and scribe the hole distances and hole diameters.	Hole diameter to be specified by the instructor or bit shank/square tang to be measured at the real bit.
5. Select the bit and chuck it in the bit brace.	Use auger bits, if possible.
6. Mount the hole depth setter.	Hole depth depends on the bit to be stored.
7. Bore holes of equal diameters.	Vertical hole axis is important!
8. Replace the bit.	Smaller holes are to be bored for bits of smaller diameter.
9. Mount the hole depth setter.
10. Bore the holes.	Repeat replacement of bits and boring until all holes are produced.
11. Check the results.
