Instruction Example 01.3. Nailing of a Tool Kit

In this instruction example, the simple nailing techniques in long wood and nailing with overlong nails are practised.

Material

2 boards
thickness: 14 mm
width: 200 mm
length: 500 mm
2 boards
thickness: 14 mm
width: 200 mm
length: 250 mm
1 bottom board
thickness: 14 mm
width: 278 mm
length: 468 mm
4 laths
thickness: 16 mm
width: 40 mm
length: 210 mm
countersunk-head nails 45 mm long.

The complete wood is planed out, surface-shaped and cut to size.

Tools

hammer, pincers

Measuring and testing means

back square, folding rule, vernier caliper

Auxiliary means

firm, non-springy bench top at working height (joiner's bench), steel bar 20 x 10 mm, 300 mm long, packing blocks of wood 25 mm thick, tacking nails 25 mm long, screw clamp 200 mm

Required previous knowledge

reading of the drawing, measuring and scribing

Sequence of operations	Comments
1. Prepare the workplace, make the working materials available.	Check the completeness of tools an materials!
2. Check the material for accuracy to size and angularity.	All boards must be accurate to dimensions, cut at right angles and even!
3. Tacking of the boards with a length of 250 mm	Place both boards with the right-hand board surface onto the working plane. Put a lath flush onto the cross-cut surfaces and pin! Do not drive in the nails completely!
4. Determine the nailing points and mark them a pencil	Nailing is done in the form of a triangle according to the work drawing!
5. Nailing of lath and board according to points 3. and 4.	Put packing blocks of wood between the board and the supporting surface and drive the nails at the nailing points vertically through the lath and the board until the nail head is flush with the wood surface!
6. Remove the tacking nails
7. Prepare the nails for clinching.	Put the nail head surfaces firmly onto the bench top and fasten them with the screw clamp!
8. Clinch the nails in the direction of the grain of wood	Press the steel bar firmly against the nail shank driven through, then clinch the projecting shank and the nail point at an angle of 90°.
9. Drive the nail ends into the wood	Take the steel bar off and drive the nails back into the wood like staples until they are flush with the wood surface.
10. Mark the nailing points at the boards with the dimensions 200 mm and 500 mm	The nails shall be driven into the narrow surface of the laths and not into the cross-cut wood!
11. Tack the boards of Nos. 5. and 10. so as to produce two nailed comers	The board of operation No. 10. with the cross-cut edge being flush and at right angles is put onto the lath (5.) and tacked.
12. Nail and pull out the tacking nails	Drive in the nails vertically and flush with the surface.
13. Put both nailed corners together, tack and nail them
14. Determine the nailing points at the bottom and mark them with a pencil
15. Lay in the bottom board and nail	Drive in the nails at an angle alternately towards the left-hand and the right-hand side.
16. Final check	Check with your eyes whether: - all nail points stick completely in the wood; - the wood has been nowhere splitted visibly; - no wood fibres have been torn out.
