SIdea - Cable Tower for a Rail Launcher:
A cable tower is a tower made out of pipes that hold the cabling for the igniters. The advantage is that the cabling can be near the motor, hopefully protected, and have a strong secure method of attaching the wires.
Some improvements that I am
considering:
Add a round metal shield over the end piece to further protect the
wires.
Switch to a stranded extension cable for cabling that exits
the conduit and is connected to the control box.
Metal conduit piping.
Bottom piece was
cut at an angle to make it easier to push into the ground.
Overall view of piping. This would be mounted upright next to the rail
launcher.
Feeding cable through piping.
Finished feeding cable through piping.
Close up.
Added some insulation around hole for cable.
Added an electrical plug. This was hard to do for
solid wire. It might be better to switch to a standard extension cable.
Igniters wires are wired to this part by wrapping
the wires around the solid copper wires and then use wire nuts.
Metal tape is over the cable to help protect the cabling from heat.
Igniters wires hooked up. (It might help to add a
round metal shield mounted on the top of the receptacle box to further
help protect the wires from heat and flames.)
