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).
