Please note that I used #8 washers for the 4 mm
machine screws. This is only because they are cheaper than
their 4 mm counterparts.
The first step is to install the shaft supports as shown in
Figure 2. The supports are held in place with two #6-32 x
1-1/2” machine screws. The mounting holes in the front
and rear braces are all oversized at . 26” in order to give the
#6 machine screws some latitude for adjustments.
The screws are secured (Figure 3) with a 3/16”
washer, #6 washer, #6 lock washer, and finally a #6-32 hex
nut. At this point, the nuts should only be finger tight. The
shaft supports should look like the ones shown in Figure 4.
Next, the shafts are inserted through the rear brace
and shaft supports, then two 8 mm trucks are added as
shown in Figure 5. The shafts are pushed through to the
opposite side and secured with the set screws on the shaft
supports as shown in Figure 6.
