This example serves to practise boring out of faulty spots in solid wood for subsequent setting of end grain dowels.
Material
Planed boards of deciduous (hard) wood and coniferous (soft) wood for various operations.
The boards may have any dimensions but should have defects like loose knots, black knots, resin galls, etc.
Tools
Bit brace and Forstner auger bits of various diameters
Auxiliary accessories
Work bench or carpenter's bench, adhesive, end grain dowels of various diameters
Necessary previous knowledge
Properties of wood, influence of wood defects on the use-value properties of the finished workpieces

Sequence of operations |
Comments |
|
1. Prepare the working place. |
Check the boring tools. |
|
2. Put the defective board or part on the work bench. |
Surface to be bored must be in horizontal position. |
|
3. Check the right and left sides of the wood for defects. |
Find out the wood defects to be bored out. |
|
4. Chuck the Forstner auger bit with the required diameter into the bit brace. | |
|
5. Bore out the defective spot. |
Hold the boring tools in vertical position and bore out to the necessary depth only (depending on the defects). |
|
6. Glue in the end grain dowel. |
Make sure that the direction of the wood grains is correct. |
|
7. Check the surfaces. | |
