The base layer is bolted directly to the table supports using 3/8 x1 1/2” carriage bolts (included in the
hardware kit). Position plywood on table frame to locate mounting holes, according to the table draw-
ing. It is imperative that the table drawing is followed on this step.
Clamp the sheet down to keep it from moving, then use an 1/8” drill bit to drill pilot holes through the
cross-support holes up through the plywood. It is not necessary to drill out each hole. It is recom-
mended to use every other one, creating a “checkerboard” pattern across the table.
Note: If installing a vacuum table, refer to vacuum table instructions.
Use a 1” Forstner or spade bit to drill a counter bore
deep enough for the head of the carriage bolt to sit
below the surface of the plywood.
Drill pilot holes with a 3/8” bit and press the car-
riage bolts into the clearance holes and through the
cross-supports. Use a mallet to tap bolts through if
necessary.
Measure the spacing and location of the sheet one last
time to make sure that it is positioned according to the
table drawing.
Use the included 3/8” flat washer and hex nuts to secure bolts to bed.
Spoilboard
The spoilboard is a sacrificial layer of 3/4” Medi-
um-Density Fiberboard (MDF). As it gets damaged
over time, it can be re-surfaced to a perfectly flat work
surface until the entire board has been used up, and
then simply replace it with a new sheet.
Spread a thin, even coat of glue across the entire sur-
face of the base layer. A cheap paint roller works great.
Have someone help set the MDF sheet(s) onto the
base. Place the spoil board on top of baseboard with
1/4” of overlap on all sides.
Place clamps and heavy objects onto spil board to help glue
cure.
