Setting Up Your Grinder XL Unit
Firstly, make sure your Grinder XL Unit is working safely before you commence. It is very important to get a ‘Hollow Grind’ in your Comb and Cutter. In order to do this you must finish off grinding in the correct position.
Here is how…….
Comb Grinding (Sharpening)
Hang your pendulum with your comb on it from the grinding hook.
With a comb on your pendulum and the grinder switched off, extend your pendulum to the middle of the disk and let it hang.
The comb should be an equal distance between the outside and inside of the disk. Adjust your grinding hook to achieve this.
The comb should be 1cm away from the disk when left hanging.
Make sure the heel of the comb touches the disk before the tips of the comb do. Take the comb off.
Draw a line from the middle of the shaft to the end f the disk using a pencil.
Hang your pendulum and adjust up or down until the comb pins of the pendulum are equal to the line on the disk.
Then move the disk so that the line is parallel to the ground.
Always make sure on your pendulum that your comb pins are in the ‘up’ position.
You will now achieve a hollow grind on your comb.
Cutter Grinding (Sharpening)
Hang your pendulum with the cutter on from the grinding hook.
With the grinder switched off, extend your pendulum so that the cutter is in the middle of the disk. The cutter should be an equal distance between the outside and inside of the disk.
The cutter should just be touching the disk slightly with the heel of the cutter touching first, when left hanging.
Take the cutter off.
Draw a line across your disk and repeat the remainder of the set up used above for the comb.
Always make sure on your pendulum that your cutter pins are in the ‘down’ position.
You will now achieve a Hollow Grind in your cutters.
You need enough steel off your combs and cutters (blades) so there is a new shiny sharp surface.
Start close to the centre and swipe your cutter 2 or 3 times across the grinding disk from left to right and back again. You need to finish the grind in the centre of the disk with sparks coming off all teeth.
Start close to the centre and swipe your comb 4 or 5 times across the grinding disk from left to right and back again. You need to finish the grind in the centre of the disc with sparks coming off all teeth.
When checking your combs and cutters to make sure there are no dull spots tilt your blades into the light. If there are any dull spots on your comb and cutter, it means they are not sharp enough. If you do see a dull spot, then simply regrind until that dull spot disappears.
You will then have a perfectly matched sharp comb and cutter combination, ready to go.
Some handy tips about grinding are:
Keep children well away from the Grinder XL Unit.
Use only 40 combs per 1 grinding coarse emery paper before changing the paper.
You should always start each new shearing season with a new emery paper.
Use only 80 cutters per 1 grinding fine emery paper before changing the paper.
Always use the appropriate safety equipment to grind with. Ensure you have goggles or safety glasses on before you start grinding.
Always wash your combs and cutters thoroughly before grinding.
Normal dish washing liquid with warm water to cut through the lanolin from the wool should be used to get your blades really clean.
Never drop your grinding pendulum.
Oil all stored combs and cutters after grinding to help prevent rusting of your blades.
