Building the secondary cage

	Six maple wood sections are used.
	The sections are jointed and then glued.
	Cutting circles are drawn.
	The ring is cut with a router.
	This is how the secondary cage looks like when it is finished.
	A storage box was built with the leftovers. At the bottom, you can see the heater installed to eliminate the dew buildup when the telescope is stored.
	The secondary cage is stored in its box.
	The storage box also doubles as a worktable during the night!
	The secondary cage is held to the trusses with theses compression brackets. Here, the knob is in the install position.
	When the knob is tightened, the secondary cage is held very securely.
	The secondary holder was modified to allow tool-less collimation. Also, as a security measure, a string keeps the secondary holder with the spider vane in case it would fall off while the telescope is pointing to the zenith!

	Same connector with the cable from the primary box connected. This cable runs in the truss pole.
	The dew heater takes its power from the secondary cage poles. No cable goes directly to the heater.
