Mount the table surface (for non-vacuum tables)
Please note:
If you are installing a vacuum hold-down system on your machine, please refer to the specific
installation guide for vacuum tables. The following instructions will not be correct for your setup.
If your table size is greater than 96x48”, you will need to tile multiple sheets to cover the full working area.
Refer to the table drawing at the back of this guide for specs and measurements specific to your machine.
Base layer
The base layer of your table should be a sheet of
3/4” cabinet-grade plywood.
When choosing plywood, keep in
mind that a higher number of plys typically creates a more stable board that is less likely to warp (in other words,
don’t use cheap 5-ply utility sheathing!)
This layer will be bolted directly to the cross-supports using
3/8 x1 1/2” carriage bolts
(included in your hardware
kit). To locate the mounting holes:
Position the plywood on your table frame according to the table drawing.
It is imperative that you follow
the table drawing on this step.
Clamp the sheet down to keep it from moving, then use a 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… we recommend
using every other one, creating a “checkerboard” pattern across the table.
Moving back to the top side, use a 1” Forstner or Spade bit to drill a counterbore deep enough for the
head of the carriage bolt to sit below the surface of the plywood.
Drill out the pilot holes with a 3/8” bit.
Press the carriage bolts into the clearance holes and through the cross-supports, using a mallet to tap
them 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 the bolts
For illustration purposes only. Hole size/spacing is not to scale.
