Assembly
Stand
Assemble the stand according to the figure.(Fig. 3). Take
care that screws are not tightened at the same time. Thus it
is easier to position mounting holes and fix the screws. (See
the following schematic drawing)
Introduction
On principle short-fibred harder wood stored in a dry place
is more suitable than long-fibred soft fresh wood.
Wood from fruit and leafy trees and walnut trees are very
suitable.Prepare the wood preferably by saw cutting for the
thickness later required (possibly also by splitting). It
should be stored without sun radiation in a dry and
properly ventilated room.
Approximate rule for wood drying: for the thickness of 1
cm = 1 year.
Thus one can avoid wood cracking by far.
PREPARATION
Unmachined pieces or wood to be turned must be balance
centred between carrying side (machine side) and the side
of collateral run (tailstock) to avoid accidents as a result of
possible tearing the workpiece off during machining! Pay
attention using roundwood or timber coming in parallel
direction if possible.
Determine the centre of your unmachined piece by drawing
whilst determining the centre using a pin or marking awl and
using the ruler or centring angle (available as optional
accessory). (Fig.. 4)

Basic terms
Roughing: Thick and strong removal of workpiece material
to form a rough contour (revolutions 800-1500 rev/min.).
Smoothing: Tiny, fine chip removal to produce fine contours
(revolutions 1500-2000 rev /min.).
Grinding: Final working up the workpiece using abrasive
rope or paper (revolutions 0-2000 ot./min.).
Polishing: working up the workpiece using a cloth or fleece
with allowance of polishing agents – pastes, oils, agents for
wood treatment or greases (available as optional accessory.
Attention!
Pay more attention to machining of a workpiece with
grinding and polishing agents due to adhesive forces
generated on instruments!
E.g.: Risk of accident resulting from captured and torn
off cloth, fleece etc.
Assembled lathe with stand (Fig. 1).
Finally assembled lathe with clamped copying template (Fig.
5).
COPYING ARM INSTALLATION
Insert the copying arm between both holding butt straps
located at the slideand shift the joint pin (item 73) to the
bearing opening. Tighten nuts at both sides (Fig. 6)
ATTENTION: Do not tighten too firmly, the arm should stay
movable.
SLIDING WHEEL INSTALLATION
Shiftthe sliding wheel to the sled axis.
Securing is done using the Allen screw at the circumference
of the sliding wheel (Fig. 7)
TOOL SUPPORT INSTALLATION
Mount the supporting tool holder and base plate to the
machine bed and tighten. (Fig. 8) Then the tool support is
fixed by clamping bolt in the supporting carrier of the tool
(Fig. 9). Place the tool support as close to
the workpiece as possible.
Attention!
The workpiece must not be in contact with the tool support
during turning. Turn the workpiece by hand before you
start the work to ensure it runs freely.
Turning
REVOLUTION ADJUSTMENT
Thanks to the special gearbox with variable belt pulleys the
machine revolution can be adjusted continuously allowing
exact analogue adjustment of revolutions being indicated in
digital form at the gearbox. (Fig. 10)
Revolution adjustment must be performed on running
machine to avoid the damage of the belt gearbox.
Roughing:
800-1500 U/min.
Smoothing:
1500-2200 U/min.
Attention!
Always lower the machine revolutions to the minimum value
before its stopping; its starting again will be made much
easier thus.
Roughing and smoothing: lay the turning chisel – see the
figure – down on the tool support holding it with both hands
firmly and safely and take care that chip removal takes place
at the central axis height and sufficient stressing angle is
available (see schematic drawing). Use only exactly
sharpened and sharp turning tools. (Fig. 11).
CARRYING POINT REMOVAL
To remove the carrying point direct the ejecting broach from
the left side of the machine through spindle hole (Fig. 12)
and strike the carrying point strongly from the cone (this also
holds for all clampable tools with conical grip MK2)
TURNING WITH FACE PLATE
To turn plates or bowls remove the carrying point (Fig. 12)
and turn the face plate to the spindle thread.
ATTENTION: Secure well using both bifurcated wrenches
that make part of the delivery!
TIP: Unmachined piece should be cut longer than necessary
and fixed to the face plate with screws. (Fix it in the centre
to avoid improper balancing!)
Copying turning
For copying the copying arm must be installed between
tailstock and carrying point. To place the copying device
between tailstock and carrying point or face plate the
gripping screws on the tailstock must be dismounted
(Fig. 14) and the tailstock must be removed.
Now the gripping plate should be split by loosening both
screws (Fig. 15) Having this done the plates are to be
removed (Fig. 16), again replaced behind the copying arm
and tailstock reinstalled.
Copied original will be clamped between centring points of
copying grips. Now moving in (holding-down pressure of the
copying arm) can be adjusted using stressing screw (Fig.
17)
Copying tool should be set to the largest diameter.
The workpiece is then moved along the whole length of the
copying pattern uniformly until any chip removal occurs.
Copying tools are adjusted by turning the hand wheel and
secured by clamping screw until required contour or
required diameter is attained (Fig. 18).
