■ Note You might also consider buying a 3' length of threaded rod and cutting two 13” lengths instead. This will

give you a longer bit of rod sticking out from each side of the machine but you can later use this extra length to
secure the machine to a plywood base, for example, where you can mount the power supply (see Chapter 18) and
make the machine more stable.

Insert a single threaded rod, as shown in Figure 13-19. Note that each rod will have two nuts
between the Lower Structural Sides as well as one on the outside of each Lower Structural Side.

Figure 13-19. Add two threaded rods to control the tension on the Table.

Do not tighten the inner nuts yet; you'll perform this step once the Table has been added. Add the
second threaded rod to the rear of the machine (see Figure 13-19) and secure it with nuts. Figure 13-20
shows the two tension rods added and secured with nuts.
