7. General description of the product
7.1. Description of the use
The machine is primarily used to knead or condition polymer clay. The material is inserted between the rollers and extruded/compressed by turning the crank. When the material has passed through the mechanism, it can be folded in half and inserted again between the rollers. This procedure is repeated until the material is sufficiently conditioned and supple.
Once the material is conditioned, you can alter its thickness by adjusting the offset between the rollers.
Mixing polymer clay of different colors (‘blending technique’) represents another use of the device.
7.2. Technical description
This polymer clay machine consists of the actual mechanism, leg and a base plate and has three gears with teeth placed at a constant distance from the centre. The gears are fixed to the device’s frame. The drive gear meshes with a pinion (a small gear) providing a gear ratio of 2:1, thereby reducing the force needed. The mechanism is also equipped with an Oldham coupling which is located between the drive gear and the sliding roller shaft. This coupling allows a smooth adjustment of the offset between the rollers. With this system, the offset, or opening, between the rollers can be varied from 0 and 18 mm.
The rollers have two U-shaped cleaner/scraper blades at the bottom attached to the frame with two bolts. This ensures easy operation and cleaning (loosen the two bolts and remove the cleaner/scraper blade for cleaning).
The device is designed for manual operation using a crank which is attached to the rollers with a 2:1 speed reducer. This makes it easy to knead solid and thick blocks of polymer clay. Optionally, the machine can be fitted with a hexagonal shaft adapter to which a cordless drill can be connected via a speed reducer (see the relevant chapter for guidelines for using the device with a connected cordless drill).
The machine can be secured to a table with a carpenter clamp or any C-clamp, which is not included. The machine is equipped with magnets and sheet metal rest pads. The rest pads can be placed freely and stuck to the table (observing the prescribed pitch) using double-sided tape (supplied together with the rest pads). This system (magnet + sheet metal rest pads) makes for a very simple way of securing the machine on a table. To disengage the machine from the table, just push it lightly away from you or move the magnets together away from the rest pads to break the magnetic grip holding the machine firmly on the rest pads. Further rest pads can be stuck at various locations to create an ergonomic arrangement on your work table that reflects your needs (spare rest pads may be purchased).
A – linear setup
B – rollers
C – lifetime bearing solution
D – crank handle (gear solution 1:2)
E – extension for cordless (accu) drill / handle
F – Oldham clutch
G – magnets (4 pcs)
H – metal magnets pads (4 pcs)
X, Y – supporting screws
8. Assembly and disassembly of the device/mechanism
8.1 Mounting the legs
Please watch Unboxing and Assembly Video (click to jump up to the video section on this page).
Loosen the screws holding the blades and remove protective foam/paper located between the rollers.
Screw in hexagonal bolts (Squirrel 20 only) and then attach the leg using 8 bolts.
Place the mechanism with the leg onto the base plate and secure it with 4 bolts.
8.2 Attaching the adhesive rest pads on the work table
Attach the sheet metal magnetic pads with self-stick tape to the table. Alternatively, you can secure the rest pads to the table with small screws (the tabletop will be irreversibly damaged, so this is done at your own responsibility). It is important that you observe the offset between the rest pads. You can decorate the rest pads your own sticker which matches the color of the table. The base of the machine contains 4 special strong magnets allowing the device to be snapped onto the rest pads just installed on the table.
8.3. Installation of the cleaner blades
Attach both blades to the rollers. Secure both blades with the bolts by screwing them into the designated holes. The bolts must be properly tightened to ensure sufficient contact between the blade and the roller for optimal cleaning effect.
8.4. Installation of the crank
Your device may be powered manually by you through the use of a crank. First, screw two M8 nuts onto the pivot arm of the drive, and then screw on the crank. Tighten the nut closest to the crank using the key tool that is provided in your kit. Next, tighten the nut closest to the device. Tighten it so it is secure against the first nut. This procedure ensures that the crank will not loosen and fall off during operation.
8.5. Installation of the hexagonal shaft adapter
In the case that you want to use a cordless power drill instead of the manual crank to drive your device, you will install a hexagonal shaft adapter instead of the crank. If the crank is installed, remove it before proceeding.
Screw two M8 nuts onto the pivot arm of the drive, and then screw on the hexagonal shaft adapter after them. Tighten the nut closest to the hexagonal shaft adapter with the key tool in your kit. Ensure that it is firmly against the hexagonal shaft adapter. Tighten the second nut so it is secure against the first. This procedure ensures that the hexagonal shaft adapter will not loosen and fall off during the operation.
Stick the laminated ruler on the sliding cover of the sliding roller. The edge of the top cover shows the size of the gap (see the fig. below – showing 3 mm / 1/8‘‘ gap). Watch video.
8.7. Mounting and dismounting the machine’s covers
The upper cover includes two stoppers. Glue these two parts into their position to prevent the clay from entering into the mechanism.
The covers protect the machine from dust and ensure your safety and comfort. We recommend that you do not remove the covers, and contact the service department if any repairs are needed.
Decorate your LC Machine
Stick this stencil to the linear setup wheel using double-sided tape. Or use it to make your own design from polymer clay. The online tutorial is here.

12. Operation and functional description
12.1. Kneading polymer clay
Insert the polymer clay into the opening between the rollers and turn the crank to compress it. Once the slice has passed through the mechanism, fold it in half and insert it again between the rollers. This procedure is repeated until the material is sufficiently conditioned and supple.
Once the material has been conditioned, you can change its thickness by adjusting the offset between the rollers.
Mixing polymer clay of different colors (‘blending technique’) represents another use of the device.
12.2. Adjusting the offset between the rollers
The offset can be adjusted in the range of 0 to 18 mm. Before changing the offset between the rollers, make sure that the support bolts are loose (in case you want to increase the offset). If the knob will not turn when increasing the offset, you need to loosen the support bolts or you have already reached the maximum offset.
NEVER APPLY FORCE WHEN TURNING THE KNOB AND THE SUPPORT BOLTS.
Applying excessive force may strip the screw. LC Tools is not liable for the damage.
The offset itself is adjusted using the knob on the machine. By turning it counter clockwise, you increase the offset. When you turn it clockwise, the offset between the rollers is decreased. If the rollers reach an extreme position, do not try to continue turning the knob by force as this might block the sliding mechanism.
12.3. Locking the roller motion
If you want a polymer clay slice with a specific thickness, lock the rollers in the desired position using the support bolts. Tighten the screws gently until they are secure against the opposite sliding roller frame. This sets the clearances for precise operation of the rollers with the specified offset.
We recommend that you use the support bolts at all times in order to extend the life of the sliding mechanism.
12.4. Attaching the device to the table
There are several options for securing your LC Machine to your work surface. Use the one that is best for you.
1. Use a carpenter clamp or any C-clamp to secure your device. Clamps are not included. Try not to damage your work surface; LC Tools is not responsible for damage to the table.
2. Use the sheet metal rest pads, which can be easily stuck to the table, and the magnets which are part of the machine’s base. By placing the magnets on the sheet metal rest pads, the machine is secured by magnetic force. To release the machine, push or pull the machine lightly from or towards you to disengage the magnets. The magnets will move away from the rest pads and the magnetic grip will be broken.
Lifting the machine from the rest pads may be somewhat difficult due to the weight of the machine. Take care to avoid injury or strain to your back muscles.
You can remove the metal sheet rest pads by tearing them off from the tabletop. Carefully remove any remaining adhesive from the tabletop using toluene (or another adhesive solvent) – keep in mind that toluene is a dangerous substance!
3.Using the sheet metal rest pads as in option 2, bolt the rest pads to the table. This may damage the table top. LC Tools is not liable for this.
12.5. Prior to the start of work, check that:
• The machine is correctly placed/secured on the magnetic rest pads or clamped securely
• The crank and the reverse-thread nut are properly fastened, secure and tight
• Clean the scraper blades and make sure that they are fastened
• Set an appropriate offset between the rollers
12.6. Adjusting the opening between the rollers
Turning the adjustment knob causes the roller to move in a linear motion, increasing or decreasing the offset between the two rollers. Lock the roller in the desired position with the support bolts.
12.7. Direction of the crank’s rotation
Insert a polymer clay block between the rollers and turn the crank forward to extrude the material through the mechanism.
12.8. Securing and releasing the device
If you need to put the device away or move it elsewhere, tear it off lightly/flip it away from the magnetic rest pads (on mounting the rest pads see chapters 8.2. and 12.4.) and then simply re-attach it. If it is clamped, release the clamps.
12.9. Tightening the cleaner blades
To achieve the best results, make sure that the bolts holding the blades are properly tightened.
12.10. Using a cordless drill as a motor
Unscrew the crank and attach the hexagonal cordless drill adapter in its place and secure it with a reverse-thread nut, as described in sections 8.5. and 10. We recommend that you place a Cardan joint between the hexagonal shaft adapter and the drill chuck to eliminate axial misalignment. Cardan joints can be purchased at a hardware store.
Use one hand to control the drill. A maximum speed of 280-350 rpm is needed when using the LC Machine.
13. Service and maintenance
13.1. Regular maintenance after each use of the machine
When you finish work, clean the mechanism with a dry cloth or brush. Do not clean the mechanism with sharp objects (knife, scraper, screwdriver, etc.) and do not wash it with water. Do not use solvents, alcohol-based cleaning products or other aggressive chemical cleaning products, as these may permanently damage plastic parts.
13.2. Cleaning the rollers
To clean the rollers, remove the cleaner blades, turn the adjustment knob to increase the offset between the rollers and clean the rollers from the bottom with a wet cloth. Wipe the surface of the rollers with a dry tissue/cloth. This can be done when the device is upside down.
13.3. Cleaning the cleaner blades
During use, clean the cleaner blades on the rollers from time to time and whenever needed. Unscrew the 2 bolts to release the blade, take it out and clean it again with a wet cloth and then wipe it dry. Then screw the blade back on. Repeat this procedure for the second blade as well.
13.4. Cleaning the surface of the machine
During use, polymer clay may get stuck to the surface of the machine. You should remove this material to prevent build-up and smearing other items. Remove the material carefully to avoid scratching the surface.
LC Tools products are made from high-quality materials which are subject to continuous quality control. They come with a 2-year warranty (a 1-year warranty for cleaner blades). The warranty does not cover damages caused by improper handling and manipulation which is inconsistent with the instructions specified in the product manual.
