		  and using jig to aid alignment
		+ mask fins at airframe ID, and MMT at rear ring leading edge
		+ apply fin to fin glass
		+ mark and cut fin slots in fin can airframe tube

		+ prepare two terminal strips with leads for aft charges
		+ install terminal strips on zipperless coupler ring

		+ mark and cut hatch in fin can airframe tube

		+ cut phenolic coupler section to form ebay lip
		+ mark coupler for access hatch
		+ drill hatch and coupler for hold-down screws
		+ cut access hatch in coupler section
		+ install blind nuts in coupler section for hatch screws
		+ countersink hatch for flat-head screws
		+ install a thermistor in MMT near aft end

		+ install coupler section over electronics
		+ install fin can airframe, aft ring dry-fit only
		+ install zipperless coupler
		+ install zipperless coupler forward ring, routing wires aft

		+ install aft ring
		+ install tail cone

		+ fin to airframe exterior fillets

		+ mount electronics in fin can
		+ attach fin and MMT thermistors to TeleScience
		+ install final thermistor in airframe, attach to TeleScience

		+ mark and drill hatch for static port positioned to allow
		  operation of power switch

	- airframe
		+ fit eye nuts to 1/4-20 rod through bulkhead using fender 
		+ install Pro75 6xl case with forward closure attached in
		  completed fin can
		+ measure forward-most extent of eye bolt on motor from 
		  airframe seating surface on fin can to know where to put 
		  the bulkhead

			29" from airframe rear to bulkhead aft face

		+ epoxy bulkhead in airframe with coupler rings fore and aft

		+ load main chute and related recovery components to determine
		  required length of forward bay aft of nose cone
		+ mark and cut airframe to length

		+ machine a pair of 1515 rail buttons for countersunk screws
		+ drill and tap aft fincan ring and airframe bulkhead for
		  1/4-20 rail button screws
		- vent holes in fore and aft bays
		- drill and tap for 2-56 nylon shear pins forward and aft

	- nose cone
		+ pick up nose cone from Jeff Lane
		+ cut ring and bulkhead
		+ dry-fit ring and bulkhead in nose cone, mark and drill
		  for attachment screws
		+ install T-nuts in ring
		+ epoxy ring in place
		+ fabricate sled structure and attach to bulkhead
		+ install electronics on sled
			+ TM v1.1
			+ TeleScience
			+ 900mAh lipo
			+ power switch
		+ static vent hole
		+ install 4-screw strip on bulkhead for forward charges
		+ attach embedded thermistor wires to TeleScience board
		- replace t-nut that got pushed out of ring
		- clean up threads on all 4 t-nuts

	- ground test
		- verify electronics
			- forward TeleScience .. make sure chan 2 not in use
		- load airframe as if for flight
		- verify RF connectivity to both electronics setups
		- prep and fire forward and aft charges to confirm deployment

	- paint
		- prime fin can and airframe
		- sand as smooth as possible
		- paint fin can black
		- paint patch on front of airframe black
		- apply "2YikStik" mask over black area
		- paint airframe gold
		- remove mask from lettering
		- sand everything with wet/dry paper, polish
		- purple Altus Metrum decal on airframe tube
		- holographic decals on two fins?
		
		- Jeff's nose cone to be left unpainted for video, 
		  maybe paint it gloss red later
