Instruction Example 2.4.: Grating

For producing ledges for a grating, milling of broad and narrow faces on the smooth and thicknessing miller is to be practises.


4 x sawn timer



1000 mm


80 mm

2 x sawn timber



450 mm


60 mm


25 mm



Smooth miller, thicknessing miller

Measuring and testing means

Solid steel squares, folding rule, vernier caliper


Feeding device

Necessary previous knowledge

Reading of drawings, measuring and testing “Manual Woodworking Techniques - Planing the Broad and Narrow Faces by Hand”.

Sequence of operations


1. Place material at disposal, set working width and depth of cut on the smooth miller.

Check the safety devices.

2. Switch on the machine, mill a broad and a narrow surface.

Take notice of surface roughness when guiding the workpiece. When milling the short ledge, make use of the feeding device.

3. Check the milled surfaces.

Check flatness of the broad face and angularity of the narrow face.

4. Set the thicknessing miller to the required size.

Take into account maximum chip removal.

5. Switch on the machine and mill the ledges to the required thickness and width.

Do not put in workpieces of quite different thickness side by side.

6. Control dimensional accuracy.

Dimensional inspection with folding rule or vernier caliper.

7. Completion:
Saw the ledge to the given length. Smooth off comers with abrasive paper. Join the ledges by bolted or nail connection.
