			- but: epoxy may actually be best:
			-after lashing, additional sanding is very tricky, both on bare wood and after sealing the wood
			-the wax from the sinew bleeds through the Dacron during the heat shrinking process

	- could be more right-angled if ripped to square section		- could be more right-angled if tablesaw ripped to square section
	- ~~simple lever/bender~~ to ~~clamp~~ stringers to ~~stem~~		- remember to note beam width amidships before cutting free of strongbacks and removing molds
			- sand ALL stringers and ribs before assembly, sand smooth
			- far easier to do at this point
			- may reduce rib breakage during bending
			- consider aggressive roundover: may reduce weight, reduce skin stress
			- station molds: put the print side of the cardboard to the inside of the sandwich! Aesthetics...
			- stringer cutting
			- don't sweat it
			- cut, then sand to shape... use motor sander?
			- consider compound miter gauge?
			- ribs:
			- mark locations on strongback before building stringers on
			- clothes steamer was adequate, may need slightly bigger tube.
			- try to leave other tasks (sanding, etc.) for interstitial work during rib bending waits.
			- use lashing, maybe not waxy, to hold ribs instead of zipties.
			- wood finishing:
			- epoxy: use only if wet look is ok, plan many coats + sanding (don't use lashing)
			- other?
			- Dacron attachment
			- spend a little more time stretching and clamping at gunwales before fastening and shrinking.
			- get better controlled irons! Arduino + PID, please
			- Dacron shrinking
			- ditto re. irons
			- Heat 'n' Bond at ~250°F, also pre-shrink fabric there.
			- Next shrink fabric at ~300°F
			- Final shrink fabric at ~350°F

- Tools that work
- Shopsmith disk sander (?" diameter)
- drum sander... need to improve it: currently just aluminum stock, abrasive-wrapped, chucked into the lathe
- table saw with featherboard
- awl/pick (piercing station molds for wiring stringers on)
- thin wire
- Tools needed
- infeed and outfeed rollers for tablesaw
- zero-clearance insert for tablesaw
- bandsaw
- Processes that work
- pencil line on strongback
- didn't do taut wire, seems ok so far
- helps that strongback is very rigid and flat
- wiring stringers to station molds:
- enables single-handed stringer installation
- assists even when workers are plenty
- adhering temporary clamp-holding wedges to stringer ends
- CA glue is easy to knock loose later
- strong double-sided masking tape may serve as well
- friction tape on angle blocks could eliminate need for adhesion to stringers
- Processes that need refinement
- assembling + adhering stem assembly
- need flat surface, nonstick (maybe bluetape)
- maybe nail in place?
- 2"x4" as station mold cleat
- adequate, but...
- could be more right-angled if ripped to square section
- simple lever/bender to clamp stringers to stem
- Redesign/Improvement Ideas
- Build Strongback with station locations planned
- Build reusable station molds with retractable stringer hookers
