Instruction Example 01.1. Nailing of a Lath Grid

In this instruction example, nailing in long wood is practised.

Material

7 laths
thickness: 25 mm
width: 40 mm
length: 600 mm
2 crosspieces
thickness: 45 mm
width: 50 mm
length: 400 mm

Medium-firm wood

Countersunk-head nails 60 mm long


Figure

Tools:

hammer, nail punch, pincers

Measuring and testing means:

back square, folding rule, vernier caliper

Auxiliary means:

spacing strip 20 mm thick, 20 mm wide, 600 mm long; firm, non-springy bench top at working height; pencil

Required previous knowledge

reading of drawings, measuring and scribing

Sequence of operations

Comments

1. Prepare the workplace, make the working materials available

Check the completeness of tools and materials!

2. Mark the outer edges of the cross members on the working plane

Putch both crosspieces at a distance of 500 mm (inside) in parallel to each other on the working plane and mark the outer edges on the working plane with a pencil.

3. Put the laths together, determine the nailing points and mark them with a pencil

When fixing the nailing points, observe the required distances from the edge so as to avoid splitting of the wood!

4. Nail the rear lath

Put the rear lath flush onto the crosspieces. First, drive in one nail on each side, check the angularity, if necessary, correct it, then drive in the second nail on each side. Prior to this, the nails ate to be upset!

5. Pin the front lath

Put the front lath flush on the cross members and pin it. Do not drive in the nails completely!

6. Nailing of all the other laths

Put the spacing strip against the rear lath, put the next lath flush onto the crosspieces and nail. Proceed in the same way with all the other laths.

7. Nailing of the front lath

Draw out the tack nails at the front lath, place the lath so that it is flush, upset the nails and nail!

8. Driving in of the nail heads

Drive in the nail heads means by of a hammer and a nail punch. It is sunk abt. 3 mm deep.

9. Final check

Visual check: check angularity, check whether the distances between the laths are all the same! The laths and crosspieces must not be splitted visibly, the nails must completely stick in the wood!
