Spoil Board Material and Precautions (Cont'd.)-
Spoil Board:
The spoil board must cover the complete table and sit on the flats around the table. If the spoil board does not cover all the
vacuum slots, the vacuum will be lost, and your job will not be pulled down onto the spoil board.
Fitting the Foam Rubber Gasket:
It is important that the foam rubber gasket is pressed evenly into the groove in the vacuum table around the zone that you are
constructing. To ensure a good seal, it is strongly recommended that the gasket be turned in at the beginning (as shown). The
gasket has a tendency to stretch while fitting, and over time it may relax and shorten. The extra length of gasket allows you to
reset it and make the seal again. If the initial turn is not put in place, there is no margin for error, and you may have to discard a
complete length just for being one inch short. It is recommended that you initially create 3 zones, each one completely across the
table. You can change the configuration at a later stage.
