List of tools:

• 1.125-inch-diameter hole saw

• Hacksaw
• Screwdriver
• Wrench
• Hand drill with No. 8 clearance drill, and No. 8 tap drill bits

Assembly:

• Side and elevation drawings of the trailer and assembled tool holder are shown in Drawing A.
• Start by fabricating the tool holder plates (Drawing B and Drawing C). The widths may vary from trailer to trailer, so all parts should be fitted before the final assembly.
• 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 .125- 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.
