Spoil Board Preparation
When you purchase your MDF spoil board it should be no thinner than 3/4 inch. Contrary to
what you might think, the thicker the MDF the better the suction that is created. However, it is
not recommended that your spoil board is thicker than 1 inch.
The MDF that you purchase will not be flat and the machine will be cutting to accuracy in the
order of a few thousandths of an inch so you will have to machine the spoil board flat. After your
spoil board has been skimmed many times and is ½ inch thick
discard it and start a new spoil board. The spoil board edges
are very porous and must be sealed. We recommend that a
hard candle wax is used as it contains no water. Never use a
water based product to seal the edges of the board as this
will make the board grow and it will be unsuitable as a
spoil board
Note:
Some glues contain water and can affect the
edges of the spoil board.
Note:
Do not confuse flatness with bow. If the board is bowed the vacuum may not pull the
board down and you will lose vacuum. Never use a bowed board as a spoil board.
1.
Cut your spoil board to the size of the bed of the machine.
2.
Place on the vacuum table. Prior to placing the spoil board onto the vacuum
table, ensure that the table is perfectly clean, free from sawdust and dirt. If there
is sawdust etc. on the table, it will change the height of the spoil board and it will
not be flat. It is strongly recommended that you do not wipe or brush the table clean, but
use a hand held blower. Do not use a vacuum cleaner as it may suck the foam seal
out of the grove and damage it.
Note: It takes at least 2 people to load a spoil board. You must never put the
edge of the board on the vacuum table and push it across. This will snag on the
foam rubber gasket and rip it with the result that you will loose the vacuum seal
and have to replace the seal.
Only lift the board into place and lower it onto the vacuum table in the correct
position.
3.
Turn on the Vacuum.
4.
Fly cut the total surface of the spoil board.
Note: Only remove the minimum to achieve a flat surface over the complete
surface. You will have to skim the surface several times during the life of the spoil
board to clean it up and you should get into the habit of only skimming the
minimum off the surface.
5.
Once one face is flat, remove the vacuum, turn the spoil board over and repeat
the process for the other
