8.0 Preparations for machining
In preparation for all processes, examine the workpiece carefully for faults that may affect the
machining process, particularly foreign bodies such as nails, staples etc.. There are many
different kinds of timber, with many different working characteristics. A skilful wood machinist
must consider the grain direction, the shape of the timber, whether it is bowed or twisted, and
the positions of defects such as knots, wavy edges etc. He should also consider any other
peculiar characteristics of the material, such as salicaceous or calceous deposits, which could
cause severe blunting and chipping of the cutters. If a number of abrasive pieces are to be
planed, use the ends of the cutter rather than the middle if possible.
8.1 Pilot Checks
Details on the correct setting of the guards, fence etc., together with the use of the necessary
safety devices, are detailed in the following sections of this manual. Prior to operation however
the following checks should be carried out (after having first isolated the machine):
1.
The blades are not cracked or distorted;
2.
The cutterblock guards are secure;
3.
The timber is free of grit, nails or other foreign bodies; and
4.
The tables are free of spanners, rules etc., and that all tools are returned to their rightful
place.
