Nova 1624 II Lathe Features at a glance
Note: Some options have a stand included! Motor & Specifications vary depending on the Country
Add on Bed System
A lathe that meets your woodturning needs, your workshop space, or your pocket! Each segment is about
20.3" in length. The feature appeals for many different reasons:
As a compact lathe (standard configuration) it is great for small
turning workshop spaces.
As an extended lathe for those wanting to do extra long spindles
(beyond the traditional between centre of most lathes) the Nova
1624/44 delivers big turning capacity. Illustrated left.
As a bowl lathe for those just wanting to turn bowls.
Sophisticated Swivel Head
Swivel head lathes have many advantages:
• Space saving
• Allows the turner (not the machine!) to decide the most comfortable position for your turning (saving
you from backstrain)
• Elimination of lefthand ‘outboard’ turning techniques and no extra outboard chucks and faceplates
are necessary.
There are a number of swivel head lathes available, but the Nova 1624 II has by far the most
sophisticated, accurate and easy to use swivel head on the market.
The Nova 1624 II lathe can be easily and quickly swiveled to any position (360 degrees). It can be
solidly locked in any position plus it has the added security of a detent pin lock at 0, 22.5,45,90 and
315 degrees (for left hand use).
The swivel head turns, locks easily and has a very accurate detent position, to lock the spindle in line
with the tailstock. Then for super accuracy the adjustable tailstock can be finely tuned for pin point
alignment (this is factory set but can be adjusted in the field). This combination of detent pin and
adjustable tailstock delivers superb accuracy and is unique to the Nova 1624 II.
Speed Range
The Nova 1624 II lathe has an eight speed range, one of the very best available. From very low speeds for large and out of balance
work through to very high speeds for small and finishing work. Some markets also have the added advantage of a variable speed
motor option (check with your reseller).
Solid Construction
Well proven design, the Nova 1624 II is made from Cast Iron
components for strength and rigidity. Added features like the heavy
duty twin bearing system, and special webbed bed design makes the
lathe well equipped to take heavy turning stresses. The bed has been
designed with vibration dampening qualities - a solid 1/2" cross rib is
positioned along the bed unit, quickly absorbing any vibration as it
travels down the bed.

ADDITIONAL SAFETY RULES FOR WOODLATHES
!
Warning! Failure to follow these rules may result in serious personal injury.
1. DO NOT MODIFY OR USE LATHE FOR USES
OTHER THAN FOR WHICH IT WAS
DESIGNED.
2. SEEK INSTRUCTION. If you are not thoroughly
familiar with the operation of woodlathes, obtain
advice from your supervisor, instructor, or other
qualified person. Instruction from a qualified
person is strongly recommended.
3. DO NOT OPERATE LATHE until it is completely
assembled and installed.
4. FOLLOW ELECTRICAL CODES. Make sure
wiring codes and recommended electrical
connections are followed and that the machine is
properly grounded.
5. KEEP WORK AREA CLEAN. Do not turn the
lathe On before clearing the lathe of all objects
(tools, scraps of wood, etc.). Keep the nearby
area and floor clear of debris.
6. CHECK SET-UP with power Off. Examine the
set-up carefully and rotate the work piece by
hand to check clearance before turning on
power.
7. DO NOT MAKE ADJUSTMENTS when the lathe
or work piece is turning. Make all adjustments
with power Off.
8. TIGHTEN ALL CLAMP HANDLES on the
headstock, tailstock, and toolrest before
operating lathe.
9. EXAMINE WORK PIECE and glue joints before
turning to make sure it has no defects that would
cause it to break when turning.
10. USE LOWEST SPEED when turning a new or
unbalanced work piece.
11. TURN AT RECOMMENDED SPEED. Always
operate the lathe at the recommended speeds.
Consult this manual for suggested speeds.
12. ADJUST TOOLREST close to the work piece.
Before turning, revolve the stock by hand to
make sure it clears the rest. At intervals, stop
the lathe and readjust the toolrest.
13. KEEP TOOL ON TOOLREST. The lathe tool or
chisel should be on the toolrest before the lathe
is turned On. Tools should remain on the
toolrest whenever the tool is engaged in contact
with the work piece.
14. REMOVE TOOLREST when sanding or
polishing so fingers do not get pinched.
15. USE CORRECT LATHE TOOLS. Do not use
spindle turning chisels for faceplate mounted work,
and vice versa. Spindle turning tools used for
faceplate turning may grab the work piece and pull
the chisel from your control.
16. WHEN ROUGHING STOCK do not jam the lathe tool
or chisel into work piece or take too big a cut.
17. DO NOT POUND WORK PIECE into headstock
drive (spur) center when turning between centers.
Pound the drive center into the work piece with a soft
mallet before installing it between centers in the
lathe.
18. DO NOT USE TAILSTOCK to drive work piece into
the drive (spur) center when turning between
centers. Secure work between centers with light
pressure from the tailstock quill action.
19. FASTEN STOCK SECURELY BETWEEN
CENTERS. Make sure the tailstock is locked before
turning on the power.
20. NEVER LOOSEN TAILSTOCK spindle or tailstock
while work piece is turning.
21. COORECTLY USE FACEPLATE. When faceplate
turning, make sure work piece is securely fastened to
the faceplate and that appropriate size faceplate is
used to support the work piece. Any screw fasteners
must not interfere with the turning tool at the finished
dimension of the work piece. Rough-cut the work
piece as close as possible to finished shape before
installing on faceplate.
22. DO NOT OPERATE LATHE IF DAMAGED OR
FAULTY. If any part of your lathe is missing,
damaged or broken, in any way, or any electrical
component fails, shut off the lathe and disconnect the
lathe from the power supply. Replace missing,
damaged, or failed parts before resuming operation.

Setting Up Your Workshop
Workshop Requirements
Consideration
Recommendation
Lathe
Location
Locate the Nova 1624 II close to a power source in an area with
good lighting. Leave clearance to all sides of the lathe; allow for
motor clearance when the headstock is swiveled. Other machines
in your shop should not interfere with the operation of the lathe.
Lighting
Your shop should have adequate lighting. The work area of the
lathe should be well lit; there should not be shadows cast on your
work. If possible, locate near a window. A movable spotlight may
be helpful.
Electrical
The Nova 1624 II requires the appropriate outlet nearby to power
the motor. Wiring and outlets should adhere to local electrical
codes. If in doubt, seek advice from an electrician. Minimize use of
extension cords.
Ventilation
Your shop should be adequately ventilated. The degree of
ventilation will vary based on the size of the shop and the amount of
work done. The use of dust collectors and filters will minimize risks
to your health.
Lathe Stand Recommendations
A sturdy and rigid stand is required so that the Nova 1624 II Woodlathe can deliver optimum performance.
A common flaw with many woodlathe installations is an inadequate stand for the lathe. The larger the size
of your turnings, the greater the importance of the lathe stand design.
Consideration
Recommendation
Lathe Height
from floor
The height of the stand should locate the centerline of the lathe
spindle at the elbow height of the turner.
Stand Top
The stand top should be flat so the lathe does not twist when it
is bolted down. Check for any gaps between lathe feet and
stand top before bolting down. Shim and prepare stand as
necessary.
Stand Weight
The stand should have enough weight and mass so it doesn't
move when turning large work pieces, and so that the stand can
absorb vibrations. A lathe stand's stability can be improved by
weighing it down with sand bags on a lower shelf.
Stand Legs
The stand should sit level on the floor and not rock.

3. Screw the Headstock Lockpin into the
threaded hole at the bottom of the
headstock. Insert the operating bar into
the hole in the Lockpin and firmly
tighten the Lockpin to lock the
headstock in position; then remove the
operating bar. NOTE: When the pin is
fully engaged the groove machined
into the pin furthest from the thread
should line up with the edge of the hole
in the casting. By doing this the pin will
be engaged in the hole of the swivel
pin.
4. Loosen the Lockpin 1 – 2 turns. Push
the Headstock Release Handle down
and rotate the Headstock so the
spindle points to the tailstock and lines
up parallel to the lathe bed. Tighten
lock pin again.
Note: Do not use excessive force when
tightening the Lockpin.

5. Remove the headstock guard from the lathe.
6. Place the motor mount plate with
attached motor over both the
Headstock studs
Tip: To ease holding the motor while fastening the guard hole (Motor cam end).
You may engage the belt at 570 rpm. By engaging the belt at 570 rpm the weight
of the motor is supported by the headstock pulley.
7. Place the headstock guard on the
headstock; part of it slips between the
motor mount plate and the motor
pulley. Attach the guard to the
headstock with six M4x10 screws.
Tighten the screws after the guard
has been correctly positioned.
8. Install a M12 washer and M12 Nyloc nut on the lower (pivoting) headstock stud. Tighten the nut until the
motor mount plate is secure, but movable.
9. Place the motor mount cam over the upper (cam) headstock stud. Install a M12 washer and M12 Nyloc
nut. Tighten the nut until smooth sliding action is achieved. Screw the Teebar into the cam.

FITTING PROCEDURES:
1. Ensure that the bed pieces are flat and the two faces of the bed (which are to be mated) are clean,
free of any burrs and dents.
Note:>>> The end of the extension bed with no feet should be mated to the lathes end face.
>>> Also, wipe off any yellow rust protective, dirt etc (if applicable).
2. Place the add on bed extension close to the lathes end
face, align the holes and screw on the four M12 cap
screws (with one spring washer each)
into the four tapped
holes with the help of the 10mm Allen key
provided.
Do NOT fully tighten the cap screws at this
stage, but tighten enough so that the add on
bed extension is secured to the end of the
lathe.

111-0516-008 15
3. Move the tailstock over the two joining extension beds (tailstock approximately covering equal length
on either extension). Lock the tailstock firmly over the joining faces.
4. Now, use the 10mm Allen key to fully tighten all four cap screws. The torque required is approximately
30 N-m (22 lb-ft).
5. Check that the tailstock runs smoothly over the mating joint, and also over the full length of the
extension. Although all components manufactured by Teknatool International are made to closest
possible tolerances, it is possible for a difference of approximately 0.1mm to put the bed 'out of true'.
The tailstock can bind in any given area in two possible ways:
A) Jamming between slides (inside the wall of the bed)
Using a smooth flat file, run over the area a few times until
the tailstock frees itself. To maintain central running of the
tailstock,
both sides must be filed evenly.
B) The Tailstock clips or appears to jump over the join
The machined flat surfaces may not be quite flush. Use a flat file
and run over the join until the 'railroad clacking' sound disappears.
Some Notes on the Bench Top:
Make sure that the bench top where you place your lathe to bolt down is flat, and is not warped or buckled.
The bed bolt points need to have flush contact with the bench.

Bolt tightening sequence
!
1. Place the lathe on the stand top. Locate the front and left corner of the lathe approximately 25 mm (1
in.) from the corner edge of the stand top. This provides a comfortable reach when turning and allows
the optional outrigger unit to be easily installed.
2. If necessary, mark the six hole locations on the top and drill M12 (1/2-inch) holes.
3. Place a spirit level along the top of the lathe bed. Any movement of the bubble as the lathe is
secured, indicates a twist on the bed. For the lathe to operate correctly the bed must not twist; if
necessary, use shims between the bed and stand top.
4. Use bolts of suitable length (not included) to secure the lathe. Tighten the two headstock bolts first,
then the two tailstock bolts, and finally tighten the two middle bolts.
5. The two 12mm threaded holes underneath the outrigger end of headstock can be optionally used
(making a total of 8 bolt positions) ensure that the bolt is a metric M12 x 1.75 mm pitch and that the
length is correct to ensure that the bolt doesn't bottom in the threaded hole and potentially damage
casting.
Connecting to Power
Follow any instructions that came with the electric motor and switch. The motor should be wired so it
rotates in a counter-clockwise direction (when facing the output shaft of the motor). A properly rated on/off
switch should be used. DC motor electronic controls may require adjustment for correct operation.
The power cord should be 3-wire, having a grounding conductor and a grounding plug. The plug must be
plugged into a matching outlet that is properly installed and grounded in accordance with local electrical
codes.
!
Warning!
Improper connection of the motor can result in a risk of electrical shock.
If it is necessary to use an extension cord, the cord should be grounded. Use the proper wire size for the
extension cord, for a given cord length, to avoid power loss and over-heating.

Note: Turning Speeds and DC Motors
Use the electronic variable speed control in combination with the step pulley. Variable speed DC motors
may have poor torque (power) at low speeds. Use the lower speed pulley steps for better torque. The
available speeds will be from zero up to the maximum speed of the pulley step.
In general, select a belt setting in the lower 4 steps to provide good torque when turning. Use the upper
steps only when higher speed spindle turning is required.

Changing Speeds
Change speeds by moving the belt position on the two 8-step pulleys. The speeds vary due to the rpm's of
the motor. Speed position can be checked by viewing the belt through the window at the front of the
headstock. Lathe Speed Selection

2. Loosen the screw knob and open
the headstock guard.
3. Loosen the Teebar and pull the
lever toward the front of the lathe
to loosen the belt. Tighten the
teebar to hold the motor while the
belt position is changed.
4. Position the belt on the selected
set of pulleys.
5. Push the Teebar away from the
lathe to tension the belt and
tighten the teebar.
6. Close the headstock guard and
tighten the screw knob.
IMPORTANT PLEASE NOTE:
Your new NOVA 1624 Woodlathe now
comes with additional safety
feature, and is fitted with an
emergency stop button on the
motor.
This button is for "Emergencies" only.
The machine will coast to a stop if
this button is pushed in.
Important: Once this Emergency
stop button is pushed, you must
release into the "OUT" position
before you can use the lathe
again. You must twist to release it
into the OUT position before you
can turn on the lathe.
• Use the regular STOP button if
you want the lathe to come to a
stop.
• To turn the machine on and off,
use the on/off switch on the
motor.
