Assembly:
- Side and elevation drawings of the trailer and assembles tool holder are shown in Drawing A.
- Start by fabricating the tool holder plates ( Drawing
B & Drawing C ). The widths may vary
from trailer to trailer, so all parts should be fitted before final assembly. (Note:
Drawings B & C are large and take a while to load).
- Cut the aluminum C-channel into the specified lengths.
- Attach the C-channel to the plates using the self-tapping screws.
- Drill the clearance holes for the screws going into the C-channel that will hold the
angle brackets to the tool plates. Use the No. 8 tap drill and drill only 1/8 to ¼ inch
deep.
- Attach the angle brackets to the C-channel using the No. 8 bolts and lock nuts.
- Once the tool holders are assembled, fit them onto the trailer. Place a Mcleod in the
holders to adjust the front holder so that the Mcleod tines straddle the trailer frame.
(The rear holder sits all the way to the back of the trailer.)
- Now mark the C-channel for the location of the cable clamps.
- Attach the clamps around the trailer frame and screw them into the tool holder.
- Attach the angle brackets to the trailer, inserting the No. 8 bolts through the brackets
and the mesh bottom of the trailer. Use the large diameter washers with lock nuts.
- Now the tools can be placed in their slots and secured with the 4- point bungee supplied
with the trailer.

has a lot of good trail work info. It's the place to go if you're into this stuff.
We have not built this ourselves yet so we can't give it our "Seal of
Reproval" yet. If you build it, let us know how it came out.
Update:
You can purchase a rack similar to this made by B.O.B from your LBS.. |
