WOODTURNING OPERATIONS cont’d

INDEXING:

There are 36 equally spaced holes in the spindle

pulley, see Fig.26. The index pin will locate into one

of these holes and will stop the spindle from turning

whilst you mark the workpiece. For example, to

locate the position of six spokes in a wheel pull the

index pin outward and turn it so that the small cross

pin locates in the slot. This will allow the index pin to

engage in one of the holes in the pulley and will

prevent the spindle from turning. Adjust the tool rest

so it is approximately at the centre line and make a

mark. Now pull out the index pin and slowly rotate

the workpiece until the pin locates into the next hole

in the pulley. Do this six times and put a second mark

on the workpiece. See Figs.27. and 28. The two

marks will be spaced 60º apart. Continue this

operation until six spokes are marked at 60º apart.

Spindle turning can be divided in the same way.

WARNING: THE INDEXING PIN MUST BE

DISENGAGED FOR ALL OTHER OPERATIONS.

OUTBOARD TURNING:

This technique would be used when the workpiece is

too large to mount conventionally. It is the same as

standard face plate turning except that because of

the size of the workpiece the turning speed should

be kept to a minimum. If you intend outboard turning

you must build a stand similar to the one shown in

Fig.29. This stand will be used as a tool rest, ensure

that when the chisel is resting on the top of the stand

it lines up with the centre line of the workpiece. DO

NOT PUSH THIS SUPPORT WHEN TURNING. DO NOT

MOUNT A WORKPIECE SO LARGE THAT THE

MOTOR STRAINS TO TURN.

When experimenting with the technique use

softwood, use heavier hardwood when you are more

confident.

The outboard turning spindle is covered by the red

plastic cover located on the pulley cover assembly.

The thread size on the spindle is

⁄4″ - 16 left hand

thread. (See optional accessories, page 41, for left

hand threaded face plates and other accessories).
