Intended Use Of The Lathe And Basic Woodturning Instructions - Record Power DML320-EP Original Instruction Manual

12. Intended Use of the Lathe
and Basic Woodturning Instructions
Intended Use of the Lathe
This lathe is designed for turning wood between centres or on the
headstock (using appropriate accessories), for sanding and applying finishes
to wood. It is not to be used for any other purpose. Doing so will invalidate
the warranty and may cause serious harm to the user.
Health and Safety
Please read the health and safety instructions contained in this manual
and the specific health and safety instructions relating to woodturning.
In addition, it is recommended to ensure your work area is adequately
equipped with dust extraction and air filtration equipment.
i
Respiratory equipment should also be used to greatly reduce lung exposure
to harmful fine dust. Always establish the properties of the timber being
turned and take extra care when working with harmful and
carcinogenic materials.
Eye protection must always be worn. Due to the nature of woodturning,
shavings, dust and splinters can be thrown at fast speeds, making adequate
eye protection essential.

Mounting Timber to a Faceplate or Chuck
Before mounting the workpiece to a faceplate or chuck, it is advisable to
shape the timber into as cylindrical a profile as possible, see Fig 12.1.
Turning unbalanced timber increases lathe vibration, the risk of it being
thrown from the lathe, increased risk of chisel dig in and makes correct
positioning of the tool rest difficult due to variable distances.
Mounting Timber Between Centres
When turning between centres, it is essential to correctly and securely
mount the timber so as to reduce the risk of it being thrown from the lathe.
It is also essential to mount the timber as centrally as possible. This will
reduce the amount of roughing out needed and also maximise the possible
diameter of the final piece.
1. Using a square or rectangular profile blank, draw two lines, one from
each opposing diagonal corner to the other, at each end of the blank. The
point where the lines intersect indicates the centre of the blank. See Fig
12.2. If using irregular shaped timber, a centre finder is an invaluable tool.
2. Take the four prong centre supplied with the lathe and place its point
directly on to the centre point of one end of the blank. Using a soft mallet
(of either plastic, rubber or wood) tap the four prong centre with reasonable
force until it bites into the timber. See Fig 12.3.
3. Carefully place the four prong centre into the headstock spindle of the
lathe, Fig 12.4, and ensure that it is correctly seated in the spindle by
tapping it firmly into place with a mallet.
4. Slide the tailstock up the bed until the tailstock centre is almost touching
the other end of the blank. Lock the tailstock in position and use the hand
wheel to extend the tailstock centre until it grips the blank firmly at the
centre point. See Fig 12.5. Then use the tailstock locking handle the secure
the position. The blank is now successfully mounted and ready to be turned.
