Bearing Holder

Tools and materials required to assemble th e bearing holder
include:

• Drill press
• Drill bits

• File

• Tap
• 1- i / 2 X 3 solid aluminum bar stock

You can buy bearing holders for the linear bearings used in this
project from the manufacturers of the bearings, but 1 decided to
make them. They are much less expensive than th e manufactured
models. I bou ght a length of 3- X I .S-inch alum inum bar stoc k
from the metal supe rmarket. From this stock I cut four pi eces 2
inches long (see Figure 7. I 9).
