Making Shelter Flashings from Door Off cuts & Pallet Edge Protectors

 Plastic strips cut from the edge of door panels (thick upvc plastic in white, light & dark brown)  are screwed to a pallet edge protectors with silicon sealent

Plastic has a tacky clear plastic film cover. This can be easily peeled off & scrunched up. This can used to block draughts in a shelter or for packaging material

Experiments with Flood Area Pontoon Boat that Forms Pillar & Wall of a Shelter When Not in Use

Experiments with Flood Area Pontoon Boat that Forms Pillar & Wall of a Shelter When Not in Use

If not required as a boat, the pontoons could be filled with soil / rocks to weigh down the floor of a shelter . Another can be raised to act as an insulated wall.

2m Long with foam core grp fibreglass pontoons & Deck made from composite door off cuts.

They are strengthened with 2m door edge strips of grp skin plastic core strips. These strips still floats & is a similar density / weight to hardwood

Wider deck (still 2m long)

Pontoons will be filled with insualted panel 2m long offcuts that consist of polystyrene, plastic & mdf. Voids will be filled with expanding foam.

Showing the 3 basic parts, 2 pontoons & a deck. If the pontoon is attached directly underneath the deck, it may only need 3 sides.

It is intended to bolt the deck to the pontoons

 Close up of top of Deck showing stregthening with edge strips & screws using Lumberjack pu glue.

I have started using self tapping torx screws which do not need pilot holes, though a bit more expensive. I dip the screw point in glue to lubricate on entry & stengthen screw join & help stop splitting. 

Lumberjack glue by Everbuild is sea water resistant

I experimented with a second type of pontoon, binding the buoyant core strips together with pvc straps & screws

Then encasing the buoyant core with a grp roofing sheet & screwing shut

Fully enclosed

Folding the front end to make it streamlined, ready to accept a nose cone or fibre glassing (undecided as yet) 

Side view

If a deeper pontoon is required, this is a posibillity, using the curved ends of a door off cut to form the stramlined bottom

Pontoons will most likely be covered in fibreglass.

Prototype Wedge Block Shelter with Grp Window Cladding & Composite Door Edge Off-Cut Frame / Corner Brace

Following on from previous prototypes here, & here,  this shelter is a lightweight, quickly constructed progression.

It is constructed by one man alone (to save labour costs)  it's currently unfinished, a work in progress

The cabinz project has support of a supplier of opaque grp profiled roof sheets at very low cost (less than £3 a mtr). These are very strong & light, & are old stock / slight seconds.

We are selling these sheets for £4 a metre (no Vat ) in the Uk, to rasie funds for the Cabinz project shelter research. The project is currently funded only by voluntary labour & small donations

We recently sold at cost & donated 140 of these grp sheets to a third party aiming to build low cost shelters in Sierra Leone, Africa. This prototype is made partly to explore options for how such shelters would be made .

The frame & corner braces off-cuts are donated free by a Uk composite door manufacturer  

Note. This prototype has been screwed together, so it can be easily remodelled.  The finished design will most likely be bolted & glued at main joints for extra strength.

The intention is to long term strength test this shelter. The roof frame alone, has been tested to 100kg load.

 End view with roof side & door to be installed

Low side view. Gutter & water capture barrel are yet to be installed 


 Corner bracing with pvc  door frame off cuts screwed on

Floor bracing as above

 Roof frame before installation.
  Note: an extra beam on each side was added later for strength (not in pic) . The cross beam on top was removed before fitting. Another will be added underneath , so roof sheets have a flatter surface to be screwed to.

Idea for Turning Infinity Bakery Solar Oven Prototype into Solar Reflective Heated Folding Shelter

Yesterday, I came across a UK Cambridge Uni team, who in 2014 Designed a solar oven  HERE

My basic idea is to use similar functions, but turn it into a shelter by having 2 facing curved reflective sides that move to form a roof at night for a shelter. During daylight sunny hours the roof folds down to heat a plinth like in the Infinity bakery.

If a bakery is not required, ir could heat water or soil / brick blocks to store heat for the cold night ahead.
Edit: perhaps this plinth could form a  work table / bed base.

2nd Edit: Having thought about the design for a few hrs, I cannot work out how to  have 2 curved reflective panels on one pedastal, so it's perhaps best to stick with one & have a seperate , removeable panel for the shelter walls. Otherwise use 2 units side to side

Cabinz Supplied 300 sq m of Kingspan Metal Skin Sandwich Panels & 140 grp Roof Light Sheets at Cost (40 donated) to Sierra Leone African Builders

 Cabinz Supplied  300 sq m of Metal Skin Sandwich Panels & 140 grp Roof Light Sheets at Cost (40 donated) to Sierra Leone African Builders

1 HC 40 ft Shipping Container of Metal Skinned Kingspan Sandwich Panels & 140 roof sheets are going to Sierra Leone to build low income shelters.

This was via a third party working with a charity in Sierra Leone

Thanks to James, our panel supplier for his donation of 40 extra sheets for free. Glue, nails, tools & other new materials were supplied for them to build with.

We hope to get some feedback in 2 months.
