7.3.11: fin/mobi`cabin/architecture
6.11.11: requirements
. the main problems to solve are
( deal with a 3-point foundation -- careful about stepping out of the
triangle
, separate the septic tank from the cabin air
-- this could be either a room divider or vent system
, 6ft of horizontal for bedding
) .
6.11.18:
. remember the recent obsession with falling cranes:
metal houses can fold faster than anythin if you don't have atleast one
strong corner
. condensate is not a problem in sleeping bags
because
there is something besides pure vapor barrier
for cushion from cold and wind .
efficiency
ease of assembly on the field
6.11.1: 3-d pre-fab's
. had planned on pre-building 2-d walls for assembly on the street;
but now see,
may be able to street-asm quicker with 3-d pre-fab's
7.4.17: frame/abs
(acrylonitrile-butachene-styrene) pipe:
. abs can form a very strong and lightweight frame
with T-joints and L-joints close together for a corner joint .
. a cube of it is attached to the trailer`frame
either by u-bolting it under the {front, back}` crossbeams,
or over the side.beams
. it might be easier to fit the bolt`backs to something like a redwood,
and then bolt that to the trailer`frame,
or just use oversized u-bolts
. the cheapest and only general way to buy pipe is 10ft lengths or more,
so if taking the bus, remember to bring your sharksaw .
smart use of space
architecture#folding
6.11.24:
. in the locked state it's folded up like a clam;
unlocked is folded down and gives more floor space .
6.11.26:
. but to also provide less wind face,
it involves a flip-down extension:
for travel, have it long and low
and balanced around the main wheels
. when camping, the rear would then flip up to provide more ceiling
space .
7.4.4:
. and to merge the 2 ideas:
as you flip it up, half of it stays down,
so you have an L-shaped hard shell filled in with soft-shell to form a
cube .
7.4.24: box`top expansion:
. motivation for a larger cabin space is ventilation dynamics:
when you have more space, ventilation control is a little more forgiving
. that control is usually no problem when done through fiberous
insulation
but good fiber insulation is expensive,
and it doesn't adapt well to changes in temperature
when higher temperatures demand greater air changes
. instead,
the insulation should be a double vapor barrier
vented with variable-sized openings,
and this system needs less manual attention when
the living space has a large volume .
. the cabin space could be expanded like that of a cardboard box:
. it has flaps (height= box`width)
that would be locked in the vert' position when lived in
. that idea can be integrated into the air con' req's
like so:
. the side flaps have 2 panes, one that forms the wall,
and the other that forms the slanted roof
. as the hard flaps are unfolded and locked into place,
the soft inner wall is pulled up by being tied to strings at each
corner
. these flaps can be constructed of abs pipe
and any opaque sheeting .
reuse of availables
7.4.11:
. construction materials to be reused include
clothes, egg`carton`foam, foam recycled from industry`toss,
plywood, 2x4's, and metal shelving kits .
secure
7.1.23: hardening
lockbox:
. add a lip to the inside so that even if the hinge is pried off,
the door is still held in place by a z-beam that keeps that side locked
in
the way to use carriage bolts is to drill the usual round holes,
but then as a washer, use the pre-slotted beams that include square
holes .

safety
fire supression
6.9.17: minimization of foam:
. regarding my 6.1.7 policy on foam,
it seems no safer using the foam as furniture,
and could be more dangerous;
perhaps I was thinking that there should be modularity between
the architecture and the iffy:
suppose you decide there's no place for foam on the road;
then it's going to be easier removing furniture than wall construction
. another idea is that
if you could separate the risky activities to a fireproof section,
then the foam could be part of the sleeping area;
however,
another problem is accidents:
if the mobi's involved in a collision,
then a fire could be injected into the assumed non-risky part
. a cool use for all the foam would be lining a stash in the woods,
where stuff could be dumped and hidden without getting dirty .
6.11.5: pos:
. a cool use for all the foam would be lining a stash in the woods?
the egg carton foam does degrade under certain conditions,
and maybe can't line dirt, but the nova foam could handle that
. the egg foam could be used over that, or in the cabin
(may want a friendly chat with a firefighter
about just how crazy foam reuse is)
7.2.5:
. there will be teksupply`fireblock foam to use as insulation .
7.2.15:
. fire-block foam is good only for surfaces that won't be crushed;
it's meant for within hard structures to fill cracks in the vapor
barrier
. the barrier should likely not be primarily that but something that is
more stable to both heat and vibration .
7.3.9: minimizing plastic
. perhaps plastic on roof less fire hazard if filled w water?
(eg, lay wire fence of studs, and then lay water down an inch thick)
. lighting can be done with a clear roof;
because fireproofing needed only in transit?
7.3.10:
. combustable not so bad if the cabin doesn't have much combustability?
office equipment and batt's are a common source of fire
. could minimize the amount of roof combustables by using 2 sheets of
plastic held apart keeping sides taut
rather than keeping them apart by filling them with air-filled clear
plastic wine bags
. also,
have a sheet on top so that sparks that land on the roof
are less likely to burn holes than in plastic
. some fabric must be fire resistant; find which .
7.1.10: protection
from insects and other disease vectors:
. what about foot`access to the pavement?
-- insect protection is high-priority in a driver`seat that's
hot even during winter!
7.1.26:
. dbl-nutting is much cheaper than custom carriaging
and it would also help install plastic sheet under the trailer`frame,
to prevent wasps from building nests in the tubing .
7.1.1: damage reduction during collision
. re:strdy shells when even shell-less trike needs no auto
regs.safety,
the shell can mangle worse than being thrown from a bike,
it rips as they hit you and as your ejected
wind tolerance:
7.1.12:
. the side-wind face`area should be balanced about trailer`wheels
6.10.31:
. if making the mobi very tall, and wind-prone
then also make it modular, so the tall part is just a rack
. if you run into bad weather and you can't lock it to a pole;
then you need to restrap the top to the side
to make a very squat object .
6.11.18:
. remember the recent obsession with falling cranes:
a cabin shell composed of shelving metal needs atleast one
strong corner
6.9.26:
. hard space needed only for bedding shell;
the remainder needs only structure for securing packages;
7.2.15: actually:
the bedding only needs a space that doesn't invite vandalism;
only the dog.guard needs hard space
. the idea is that camping is done only in isolated places,
and that while parked in the city,
only things that look ludicrous or easily damaged will tempt vandals .
7.2.24: passing clearance:
. drivers need give you less space while passing you if
your cabin`s left side is less wide than your wheel,
allowing sure clearance of their side-view mirrors .
7.3.2:
. along with the decision to have the width extend to the tires,
the passing-clearance constraint still depends on the height
7.3.2: mirror clearance:
. along with the decision to have the width extend to the tires,
the mirror-clearance constraint still depends on the height:
. if atleast the right side tapered before the driver`head`height,
then the mirrors could stay within the cabin`base`width
. being tapered on that side should allow the lockbox`door to be opened
atleast 60deg
. if the driver`ceiling can't be taller than the cabin roof,
then a right-side mirror is needed,
and the right-side cabin will have to be likewise tapered .
7.1.27: rearview mirror:
with a rearview mirror placed high
it doesn't matter how high the cabin roof is,
tthe driver roof is just a bit higher ,
and controls wind by having tall sides .
. also, use a rearview under vehicle
for very clear view, but easily muddied .
rubber grammets in door will stop compression clange
. another way is to have the cabin trianguliar
but that is a huge waste of cabin space .
6.10.31: window
. need window out bathroom in case officials come when busy .
12.13: direct access to driver`s compartment:
. must get from cabin to drivers seat wo getting exposed to dogs
7.1.30:
(eg, to wait comfortably while the authorities deal with
dogs that are preventing you from getting unstuck) .
environment controls
4.7.22: evaporative cooling shell
. the car needs a sweat-cool device (water is poured down metal sides;
it evaporates and takes heat away)
. the middle layer needs soak feed .
6.11.12: identifying air con' needs
. ideas about stored goods should consider their air conditioning needs
.
7.2.13:
. eg, need side space warm for keeping the water in jerry cans from
freezing .
7.1.17: modular air spaces
. the bathroom will be a separate space that is tarped by construction
plastic as is the driver`s compartment .
7.1.23:
. bathroom modularity is somewhat interrupted by having a door between
cabin and bathroom;
but, since there is a hole in the floor,
having a plastic chimney over that hole, and containing the toilet,
can provide virtual modularity,
although there will be more heat loss in a space that should be warmer !
6.12.13: ozone venting
. must have vent for xpw and other electronics
-- my lungs were toast after a session in plastic bag with xpw .
5.12.24:
. worry about things needing warmth yet separate venting?
simply put
the venting room within the insulated room .
ventilation
7.2.22: shed
. for the lockbox`foot space, make some doors out of the lockbox`s
fridge grill,
and also add shelving
to transform that space into a lockable area that is well ventilated to
keep things that should be vented
in case they leak or otherwise give off vapors .
humidity and fungus
control
6.11.18:
. condensate is not a problem in sleeping bags because
there is something besides pure vapor barrier
for cushion from cold and wind .
7.2.21:
. with a cabin insulation tight eno' to stay warm with no heat,
it might get humid eno' to create a fungal problem
(clothes in a bag will get moldy even without humans adding to the
humidity
since most places have plenty of humidity in the air)
. on the bright side,
it might help having a clear roof that lets the sunshine in,
. should also have room-wide ventilation
rather than the idea to have a mini.chimney near head during sleep .
use breathables as doors (reuse coats or blankets);
7.3.11:
eg, have a screen door that replaces screen with reused fabric
. for a mini.rv such a fram can be made from a reused house ac filter
frame,
or a window fan frame .
7.2.24: fresh draft in living room
. the primary seal encloses both the bathroom and bedroom,
and while the seal between rooms is not perfect,
the primary vent.input comes from leaks in the bathroom`external.door
. the vent.output is a pipe in the ceiling of the bathroom;
it`s draw should be moving air from bedroom to bathroom,
and thereby changing the air slowly while keeping things fresh .
7.3.21: underside
paint:
. underside needs protection from road salt:
cover bottom with cloth smeared with fire foam (not in the sun it won't
need painting)
after foaming need to ensure it doesn't expand beyond currently built
frame
(but just 2holes in front and 2 in back are affected
-- means re drilling light metal)
evaporative cooling
and insulative heating
7.4.8:
. an evaporative cooler works the same way sweat does:
the unit is kept in the shade, and water is applied to the unit
so that as the water evaporates, it removes heat from the unit .
7.1.22: insulation
from dbl-vapor.barrier:
. the key to effective
insulation is a double vapor barrier;
other forms of insulation are simply batteries or capacitors
that delay the migration of air when there is a leak in the double
barrier .
7.4.8:
the inner.shell has to be free of insulation,
. and then the outer shell can be like a 3''-thick blanket that is
thrown over the top
. when you want cooling, you just increase ventilation;
. for a rigid arch',
the ventilation between the outer and inner shell could be controlled
by panels
that covered vents when the heat should be retained .
. for a simpler blanket-over-a-box arch',
need to send out some diagonal rods on the corners to create space
on both the top and the sides and then hot air rises,
. the vert' spaces along the walls will create a stack effect
if there is space at the top to vent the stack
. not having a straight stack can impede throughput significantly;
but, it's also important to have sun shade
. so, should have the primary vent valves be above the wall spaces
and make the outer.shell`walls a bit taller than the inner.shell`s
. to still have the sunroof:
the outer shell must be opaque, but sun can still get in from the vents,
and then the inner.shell can be clear plastic to some extent .
modularity
6.12.13:
. to help make cabin modular and easier to design,
it can be smaller than frame
7.1.6:
. the cabin is a module that is designed separately from
and can be quick-bolted to the trailer-trike .
5.11.03: kitchen modularity
. should the lp system be part of the car or on a trailer;
how else are you going to cook lentils?
perhaps instead, look into economical canned legumes .
6.9.26: modular cabin
strength
. the bedframe girders can be used as roofing girders;
they are supported by the lumber,
and after that the shell can be made without thought to it`s strength;
since all it has to hang from this foundation
rather than support it`s own weight like the shelves need to .
7.1.7: shell-dog.guard
modularity
. use a combination of cabin`shell`extension (beyond the trailer frame)
plus the dahon-mounted dog.guard
. if bringing the cabin`shell to entirely surround the rider,
then this would bring the shell out another 3ft
(
which is a lot of extra support to worry about,
even for a thin-guage metal sheeting
[7.3.2: but not for beam-wire-plastic.tarp architecture ]
)
. with a combi' design,
the cabin`shell would come up to the pivot,
and then a shell that is just big eno' for the legs
would be attached beyond that on the bike"dahon,
. the 'tween could be something like camping fabric,
[obs]
[7.3.2: --. assumes front entry by squeezing between modules .]
. the back of the dog.guard could be open
for easy stepping on the ground during driver-seat entry
by having foot-access to the pavement below
because directly behind the guard.dog would be the cabin`shell and the
fabric connecting the two
7.2.9: modularity/base and top.load modules
7.1.27:
. it needs only one strong strut in some upper corner
and then the other struts can be weak like those in the shelving kits .
7.2.15:
... not obvious to me how that could be true with a heavy load;
need atleast 2 stong points and a tight bundling,
but if you have secure tie downs,
then just one pole creates triangulations in both the x-y and z-y
planes .
. modularize cabin by making the lockbox and side struct's be one
module"base,
that can act as a foundation for either a cabin or a truck bed,
. it would have the same insulation system;
ie,
the vapor barrier starts with a sheet on the bottom
that is tied around the base module,
and then in needs
{
truck bed?
a tarp that is tied over the cargo to shed water off the bottom plastic
.
,
cabin foundation?
( cabin; upper tarp; metal siding ) .
}
. keep in mind the needs for entry to lockbox and driver`shell .
7.2.12:
. with atleast 2high hook points can use a tarp and sinch-bands to form
a truck bed .
7.5.7: bump.aware
. the cabin should be built in sections, such that during a rear-end
fender-bender,
damage to the bathroom can occur without destroying the entire cabin;
ie, all pillars of the cabin skeleton should be anchored to the
trailer`frame
rather than the L-iron and wood frame that supports the bathroom .
6.11.12: arrangement options:
configuration of
reusables
#1: [obs]
. lockbox is on it`s side and base for one of the angle.irons;
the pair of angle.irons form a strong roof struct .
#2: [obs]
. the innerbox is a base for the lockbox
#3: [@] { lockbox, innerbox}
. the lockbox and innerbox have a built-in struct & surface
that makes them good wall material,
#4: [@] mobi`dog.guard/shell
. the driver`s seat can fold down to become the bedding
--as it once was in the office;
#5: [obs]
. the girders are used on either side of the boom
to help support the walls that will go around the driver .
walls of pipe are
tanks:
. make the inner walls out of piping that doubles as tank
for fresh water, and greywater
. it might work for black water too,
but since it can be critical to change that in a hurry,
it might be better to not make it part of the wall! .
6.11.16: flooring over tires: [obs]
[7.3.2: --. this depended on a wide floor that hovered over the tires .]
. besides the idea of putting the lockbox over a tire,
another way is to use the 2x4 wood
since there is plenty of clearance
when the 2x4 are stacked just 2 high
. also the shelves can be used the same way:
lay a shelving system down so the shelves act like the 2x6 in the floor
.
6.11.28: lockbox and innerbox arrangement: [obs]
. lay the lockbox down on it`s side, and bolt the innerbox to it`s top
. this will protect the lockbox`s hinge, and during the night,
the lockbox can serve as a bed .
[7.2.16: --. decided on lockbox on back, with inner box bolted to
rear of trailer (head of lockbox) ] .
6.9.26: flooring:
( lockbox has a sections door (d) and base (b),
while the freezer (f) has a top (t) ):
. the lockbox greatest non-face side can be reused as flooring
. it would entered by having a padded bar over it,
that you would hang .
top view:

12.16: lockbox:
. ideas about fitting lockbox into cabin design
-- after finding that the plywood is exactly the right size for one
side --
include:
(1) on back, lengthwise:
. box on it`s back? no easy place for toilet [7.1.13: not true -- even
when placed lengthwise . ]
12.27: lockbox/on back not side:
. the side offers a good rise for a steering anchor,
and the door lifting up could form a shelf to sleep on,
but this would require moving the door through prime floor space --
where would the toilet space be?
. on it`s back, there is still prime floor space,
and enough room to get sleep in a fetal position .
7.1.13:
lockbox/lengthwise:
. what was wrong w lockbox being lengthwise?
. it'd be easy to attach the gym`handle bars to that
and then ecnclose wheels in shlef panels
that are easy to remove for wheel repairs
. the L-irons can still be of use on the trailer`frame
where they can support the shelf panels .
. the lockbox will
fit lengthwise;
if what I was worried about was still being able to
fit the innerbox on the end of the trailer`frame
. the inner box will balance on the end`crossbeam,
and then pushing the lockbox against that,
the lockbox`center of mass will be near the front edge of the tire .
(2) on it`s side,
sideways: [obs]
. on it`s side? cover with white tarp,
and when camping then the box`s open door would help keep the tarp
raised high
[17: and the room would be divided by the door
. the side would provide bedding space . ]-17
todo:
. can the fact that the plywood fits like that,
be used as a foundation for modules
ie, instead of consider the floor to be first and then walls,
the modularity would be sections of room
where the wall modules would come with their own flooring (17: like
modular homes do?)
26: lockbox as fenders:
. with lockbox as fenders,
then innerbox on top for the frame to take the ceiling high?
[27: if innerbox was on the floor in back, it would make most of the
bottom metal,
and it would be a nice finish for the bathroom (during stops, the
kickstands make it stable in back)
]-27
. even though lockbox is far away when dbl'ing as fenders,
the gym`handlebars can still be mounted on the bedframe`angleirons .
12.10:
. stack innerbox:
makes a wall to suppport angleiron from inner box on lockbox
[12.11: use innerbox alone as angleiron support]
12.27: freezer/on back not side:
. with (lockbox/on back not side)
[@] (on it`s side, sideways)
also could put the freezer beside it for a full-sized bed sleeping
diagonally
. then the inner box (toilet space) could go on top of the freezer and
to the side
. this seems heavy, but with all that base,
it would be easy attaching the shelving shell in a secure way .
(3) on back,
sideways: [obs]
lockbox won't fit sideways wo overlapping trailer`frame?
(1)
. parallel with frame, heavy end at wheels (deadspace near driver)
?:
. the original design called for putting the lockbox upside down so
legs useful as roof storage
. this could be modified so that legs offer pillar that holds up ceiling
. the ceiling has to be 5 feet up which is the box height;
however, that 5feet is needed only where the driver is,
and laying the box flat would offer a double floor to put gear under
bed .
(2)
. lay flat n parallel to trailer
with dead space used as fender well (when wheels are the very end of
trailer)
. it's hanging over the frame
(3)
. whats best for balance?
assuming lockbox is most of the mass,
move wheels back in the middle,
and put the box in front of wheels
and balance with books at back .
. the door opens up for reuse as table
. will fit this way only if sideways
or will fit parallel with trailer only if the walls are beyond wheels
(4) raised and lengthwise: [obs]
. if there were plywood under the lockbox, and foam,
that would help raise it so it could be pushed further forward
without running into the trailer`boom (which is angled with a forward
rise) .
7.1.17: A-irons: [obs]
. one way to both raise the lockbox, and make a place for the inner box
is putting the L-irons face down like A-irons,
and bolting the lockbox on top of them;
then the A-irons would stick eno' to bolt the innerbox to them and to
the side of the lockbox .
7.1.19:
. the L-irons cannot be bolted as A-irons
without complicating the bolting of the lockbox to the trailer`frame .
7.1.21: L-irons supporting bathroom
. the L-irons are going to assist in supporting the weight of the
bathroom
as it based on the innerbox being attached to the rear.end of the
lockbox
. L-irons are very heavy, so it would be better to keep the located
near the bottom
idea#0:
. drilling new holes in the trailer`frame should be avoided
because that metal is very thick;
however, now that we have a drill bit sharpener,
there is no reason to dread this if it would be the best design
. custom drill holes could both attach these heavy irons to the equally
heavy frame,
and also form a tight frame for the locbox that assists in sideways
rigidity
that the steering depends on .
idea#1:
. there are bolt.holes in the trailer`frame
about 2'' out from the side of the lockbox,
but this doesn't help the lockbox,
and it obstructs the side structures .
idea#2:
. bolt holes could made easily in the lockbox,
and yet would not have to take the brunt of the weight,
because the locbox would be pinning down the lower lip of the L-iron
. this needed confirmation, because the lockbox has round corners,
and it wasn't clear whether the support was really there .
innerbox stacked on
lockbox [obs]
21: steering in the way of seat
.. but maybe the steering should be arranged so it's easy to climb over
it!
[22: could climb in from the back]
7.1.19:
. some odd situations like dog attacks during breakdown,
might find it very convenient to get to the cabin from the driver`s seat
and having the innerbox stacked on top of the lockbox
obstructs passage from driver`shell to cabin .
7.1.22:
. another option is to turn the lockbox around
and mount the handlebars on lockbox`top,
so then stacked innerbox is located at the back of the cabin;
but this would require cutting the lockbox nearly in half
making room for the boom .
keeping the space
available between tire and lockbox
7.2.22: backing#1:
. wanting to keep the space available between tire and lockbox,
could use shelving metal to separate, and also strengthen the fender,
by bolting that curved piece to a flat backing
7.2.22: backing#2:
. make the side structs as planned,
so it's like a wall that covers the wheels,
but clip out the part that is covering the wheel,
and put that clip-out behind the wheel
. the fender can come from cutting a shelf in half,
and the finished edges can be on the outside
to hide the cut parts of the outer shell
. there can be a minimum of cutting if the side structs are just the
length of one shelf,
and then the shelving is used as siding by placing it hor'ly,
so, the 1st shelf is behind the wheel,
and shelves above that are outer wall panels
. whole shelves then cap the ends of the side`struct,
and whole shelves were used in every part but the fenders,
which will be half shelves cut to maximize use of space behind the
wheel
or atleast eno' to fit a walmart.reliance`jerry can .
7.2.22: backing#3:
. using the L-stands that were part of the metal table
in place of the shelving beams
would provide a much stronger support, and allow the side struct to be
reinforced with wooden studs .
keeping cabin level
7.1.30: bathroom`kickstand:
. trailer bottom`height is 10'' or less?
the kickstand should be bolted to something variable
. the bathroom`kickstand needs to pulled down from the inside,
and one way to do that is being spring loaded to stay up,
and then have a cable that forces the kickstand down
. the lawn chair parts could provide a kickstand .
31:
. check use walmart`cot`frame for use as kickstands:
the bed`s halves can be disconnected, to shorten the bed and tie the
pieces together,
and place them so the stands are on either side of the bathroom
. there could be strings
the side near the tires,
where the balance is good,
that pull the kickstands out when you wanted use the bathroom without
getting out of the cabin .
7.2.26: alt:
. instead of holding the rear end up,
the kickstand could be someway of holding the front`end down;
eg, some pipe-gripping mechanism that would hold the front corner of
the trailer`frame
to one of the many sign posts
(unfortunately there are laws against parking near signs,
perhaps because they don't want arguments about
whose car is low eno' to keep the sign visible) .
6.12.8: alt's
to jack stands
(1: trailer stand)
. those wind-up stands on trailer booms are short versions of ...
(2: cabin stand)
. stands bolted on the side of truck-mounted cabins
so your truck can leave the cabin
and use the truck`bed for other jobs .
(3: always
plumb) 6.12.9:
. with trailer`frame setting on top of inner.box
then the axle can be mounted under the inner.box,
and the inner.box`walls are raising the frame eno' to
keep it level when the dahon is underneath the front of it .
technical options
12.29: evaporative cooling vs easy vaporbarrer
. if [tarp stapled over metal shell] is the way,
then what is the best way to provide
that double layer that acts as a sun shade
while also allowing the inside to be covered with a wet blanket
for evaporative cooling?
. it seems complicated; save it for the next version .
frame
6.12.29: caterpiller
vs linear walls
. instead of sheets, the walls could be segmented by panels,
and then folded or raised as needed for mobility or space .
..
. seemed neater to have metal on the exterior,
but the smartest for rain and visibility
is to give the panels a skin of bright plastic tarp
. the metal would still be useful as a skeleton
that would sandwich the foam
and give the plastic something to stretch across and look neat .
..
. make the ceiling stiff, and it can rise at the rear for camping,
or be lowered for a tear-shape that is more wind-slick
. but this angled design gets in the way of tight paneling
. another way is that the whole roof is lowered
and the side walls fold in .
12.29: tarp stapled over metal shell:
. after considering some variations of the caterpillar,
the easiest is to build the metal-foam first
and then add the tarp later with staples
(pieces of hangerwire that tie on the other side of the wall
and form hooks to hang things on )
. the flappy part of the tarp would be pulled around to the back and
front
since the sides have the most exposure to viewers .
12.29: sunroof
. use the clear wine bags for sunroof?
not very strong but cheaply made into sheets by
putting them between sheets of construction plastic,
and sewing staples of string
7.1.17: sun.roof and metal side.panels:
. the cabin roof could stay clear and the walls metal
the side structures would have no wall panelling, just like the roof,
but then
while the white tarp would be the only thing covering the insulation on
the top,
the sides would get metal paneling over the tarp to protect it from
getting scratched
. the side panels can be lined with insulation to keep them from
scratching the tarp underneath
7.2.1: blanket bins as windows:
. make the roof and bathroom windows out of blanket boxes with a
box as side window
it also serves as shelf too bad these boxes break so easily
...
-- . the top could be done later too:
it just needs to look neat to get rolling,
not perfect .
