the top so that the
1/4” x 2” carriage
bolts don’t interfere
with your stock. I
have found that
. 28” deep works
well for these.
The T-tracks are
secured to the table
with 19 #6-32 x
washers, and hex
nuts as shown in
Figure 4. Most T-track does not
mounting holes, so
you must drill and
countersink them yourself. Simply clamp the T-track to your
table and mark the holes with a marker.
On the bottom of the table, the T-track mounting holes
will need to be countersunk and the screws cut so that they
don’t interfere with the Y carriage.
To install the T-track, place them in the slots and insert
screws into the holes. Secure with a lock washer and nut.
You will have to use a rotary tool to cut the ends of the
screws flush with the bottom of the table (Figure 5). The
drawing files for both the plain and slotted table will be
made available on my website listed later in this article.
As an option, you can forgo the metal T-tracks and use
a router to mill some T-slots into the table directly.
Attach the Table
Start by moving the Y carriage forward as shown in
Figure 6. This will make inserting the carriage bolts a little
easier. Line the 12 holes in the table with the holes on the
Y carriage and then insert 12 1/4” x 2” carriage bolts into
each of the holes as in Figure 7.
Turn off the power to the controller and remove the
motor connectors. Carefully tip the machine on its side and
add a 1/4” washer, lock washer, and hex nut to each of the
bolts; see Figure 8. Tighten the nuts. Place the machine
upright, reattach the motor connectors, and power up the
controller. Move the table all the way to the back of the
machine and then back to the front to make sure the table
doesn’t contact the sides of the machine.
