D4666 Heavy-Duty Mobile Base
Making a Base Plate
If the footprint of the machine is too small for the mobile
base or the machine doors or fixtures do not clear the
side rails, you can mount it to a base plate, as shown in
Figure 23.
A good quality base plate can increase the standard foot-
print of machines, such as drill presses, to make them
more stable. The base plate must be at least 1
1
⁄2" thick
and made of plywood (do not use OSB, MDF, or particle
board) to hold the weight of the machine.
Needed Materials for Base Plate Qty
• Plywood
3
⁄4" x base width x base length ..............2
• Wood Glue ...................................... As Needed
• Wood Screws #6 x 1
1
⁄4" ................................. 24
• Mounting Hardware .................................Varies
To make and use the base plate, do these steps:
1. Glue the two pieces of plywood together, and align
edges and corners so the two boards make one thick
piece.
2. Use wood screws to fasten boards together from both
sides.
Note: Allow 24 hours for the glue to dry before plac-
ing your machine on the base.
3. Refer to Assembly on Page 3 for assembly instructions.
4. Place plywood base plate on assembled mobile base.
5. Drill holes through base plate and bracket plates at
each corner of mobile base.
6. Secure base plate to the mobile base with hex bolts,
hex nuts, flat washers and lock washers, as shown in
Figure 22.
Note: Use 2"–2
1
⁄4" long hex bolts.
7. Place your machine on base plate, and position
machine close to front or center of mobile base, so
mobile base will not be a tripping hazard.
8. Mount machine to base plate with lag bolts and flat
washers (see Figure 23); or drill holes through base
plate and secure machine with through bolts, flat
washers, and hex nuts.
