Instruction Example 01.2. Nailing of a Halved Frame Corner Joint

In this instruction example, nailing of a glued frame comer joint with clinched nails is practised.


halved frame comer joint, glued,
thickness of the legs: 26 mm
width of the legs: 50 mm
countersunk-head nails 30 mm long, unhardened



hammer, pincers

Measuring and testing means

back square, folding rule, vernier caliper

Auxiliary means

unhardened steel plate, 200 x 200 mm, 10 mm thick, as base plate; firm, non-springy bench top at working height (joiner's bench); pencil

Required previous knowledge

reading of the drawing, measuring and scribing

Sequence of operations


1. Prepare the workplace, make tools and working materials available.

Check the completeness of tools and materials!

2. Determine the nailing points and mark them with a pencil.

Observe the required distance from the edge, adhere to the nail picture according to the work drawing!

3. Fasten the frame in preparation of nailing

Place the steel plate (base plate) at the endscrew onto the joiner's bench, put on the frame comer and clamp it between the cramp irons, fasten the frame comer with a screw clamp to the bench plate!

4. Drive in the nails at the nailing points

Observe the inclined position of the nails, the nail points must show in the direction of the grain of the lower surface. Drive in the nails with precise blows until the nail heads are flush with the wood surface.

5. Unclamp the frame comer

Loosen the endscrew, undo the screw clamp.

6. Final check

- for proper inclined position of the nails
- whether the wood surface is not deformed by the blows with the hammer
- whether the nail heads are flush with the wood surface
- whether the nail points are properly clinched and entirely driven into the wood
- for splitting of the wood and torn out wood fibres
