Instruction Example 7.4.: Laying of Parquetry - Technique: nailed on planed boarded floor, belt or ship’s bottom pattern, parquetry-fillets with movable tongues

Practising of parquetry laying according to the above technique.

Material

Parquetry-fillets with tongues, countersunk nails
(2 pieces per fillet)

Figure

Tools

Hand saw, circular saw bench, hammer, nail tongs, plane, tow hook, nail punch, broom

Measuring and testing means

Try square, flat square, folding rule, pencil, water-level, pipe-level

Auxiliary accessories

String, steel bolts, knee pad

Required basic knowledge

Scribing, sawing, laying of building components along the string, jointing

Explanations to the working drawing

1 Skirting board, 2 parquetry, 3 planed deals, 4 timber beam, 5 ceiling structure, 6 string, 7 planed boarding, 8 steel bolt, 9 1st laying direction, 10 2nd laying direction, 11 1st layer of parquetry-fillets, 12 nailing of two sides (1st layer)

Sequence of operations

Comments

1. Testing the wooden subfloor as to strength, moisture and vermin infestation.

The deals must be firmly nailed, must not project or be moist and must be free of vermin.

2. Sweeping the subfloor clean and removing the dust.

3. Fixing the middle row and putting up the string along the middle row stretching it with the help of the steel bolts.

String must be angular and parallel to the wall.

4. Distributing the parquetry-fillets and putting in the tongues on one head end.

Sort out faulty parquetry-fillets when distributing them.

5. Laying the middle row of parquetry-fillets along the string and nailing them on the subfloor on both sides with two nails per fillet, scribing the head-end cut, sawing it and laying it with the help of the tow hook, coating the last three head ends with cold glue before.

The nails are driven obliquely into the rabbet.
The nails are countersunk with the nail punch, so that in the rabbet no nail is in the way when the tongue is put in.

6. Distributing the required parquetry-fillets on the left and right sides of the middle row and putting the tongues in the fillets.

One tongue in one head end and longitudinal side, each.

7. Removing the string from the middle row and continuing to lay parquetry-fillets along the middle row, nailing each external end with 2 nails on the subfloor.

8. Cut final row, if required, longitudinally; therefore scribing, cutting to length and laying with tow hook. Coating the sides of the last row with cold glue before.

Leaving an air gap of 20 mm along the wall.

9. Cleaning the working place.
