	Conventionally, the blade guard is comprised of 2 thin semi-circular discs that are attached by a thin flat bar that spans about half the circumference of the blade. This is the design selected for its ease of manufacturing (torch a thin sheet of metal using a circle cutter, then torch the circle in half; tack weld the half-circles to a long thin flat bar then fully weld them together).

	The blade guard support is made of 2 flat bars that are each bent twice and mounted to the same fasteners used to mount the hydraulic motor.		The blade guard support is made of 2 flat bars of 25.4mm width that are each bent twice and mounted to the same fasteners used to mount the hydraulic motor.

	The blade guard support flat bars are here named the "Guard Support". Thickness for rigidity while allowing ease of bending is 3mm.		The blade guard support flat bars are here named the "Guard Support". Thickness for rigidity while allowing ease of bending is 3mm.
