Common Mounting Practices
There is no best way to mount the target system because every facility is unique. The key points to remember are:
- The mounting points must be sufficiently unmovable to withstand the constant tension of the drive line.
- Because the drive line is standard para-cord, it will stretch and sag a little in the center of span. This is normal and will not be a problem, provided that the endpoints are sufficiently high so that the target does not hit the ground when at mid-span. This is more of a problem when using the system for firearms training because target frames weigh more than a cutting flag. For firearms training, it is recommended that the corner and end pulley sets be mounted seven feet above the ground. Four feet is generally a good height for cow horse training and competitions.
Typically, control unit mounting points can be successfully created by mounting ¼ inch eye-bolts to posts or existing fencing. The control unit should be mounted at a level that will allow the user to have easy access to the controls and display panel. The eye-bolts must be placed 8 inches apart.
In this illustration, two eye bolts are shown welded to a metal post. Other examples might include screwing eye-bolts with wood screw threads into a wooden post. For horse training purposes, the target typically runs between two existing arena fences. This can be accomplished by mounting the eye bolts directly to the fence or to a sturdy board and attaching the board to a pipe rail fence with bolts or u-bolts.The control unit can then be attached by sliding the top mounting tab over the top eye-bolt and the bottom mounting tab under the bottom eye-bolt and inserting the included mounting pin.
The control unit should be mounted so that the drive line is in alignment with the pulley as shown in the following illustration. The drive line angle can be changed by changing the length of one or both of the eye-bolts.
Pulley units are typically mounted to the corner or end posts in a similar fashion.
A corner pulley is only required when you are building a three point mounting system. In this illustration, two eye-bolts are shown welded to a metal post. The eye-bolts are placed two inches apart and must be positioned so that the eye-bolt is line of sight to the control unit and line of sight to the end pulley. If the target is to be used for firearms training, the pulleys should be six to seven feet above the ground.
An end pulley is required for all configurations. This is created in like manner to the corner pulley except only one pulley is required. Height requirements are also the same as the corner pulley assembly.
Pulley assemblies are attached to the eye-bolt with a provided s-hook.
Mounting the Drive Line in the Control Unit Pulley
In-order to have enough friction on the drive pulley to avoid drive line slippage, the drive line must be placed in the pulley once. Then, a second full wrap must be made, resulting in the drive line making 1.5 wraps around the pulley.
Three Point Target Mounting This mounting method is appropriate for firearms training when the target will move between a corner and end posts which will be mounted in front of the firing line while safely maintaining the control unit on a third post behind the firing line as illustrated above.
Two Point Target Mounting This mounting method is appropriate for non-firearms training when the target will move between the control unit and an end post. The setup is the same, with the addition of a small steel ring which will keep the front and back drive lines held together as the target approaches the control unit, thus keeping the drive line from jumping off of the pulley.
