MACHINE PRESS PROTOTYPE BUILT FROM COMPOSITE DOOR OFF CUTS FOR MAKING EXPERIMENTAL DIY SIPS PANELS

 As it's not practical to ship expanded foam as it taks up more volume, and the supply of composite door panels off cuts is limited, I decided to combine the 2 & make a protoype machine using a frame & silver foil.

A similar, previous experiment with  expanding foam , Frame & grp sheet / window is HERE ( Mk 1 & 2 DIY SIPS Framed Panel with GRP Skin & Built in Window )

This was the cheapest way i could think of for making a basic panel. TO protect the oustside of the panel from the wind / rain. a metal or grp sheet can be attached or glued with foam from the start.

If a green house wall  type shelter is required for growing veg, a wider frame can be used & shelves attached to hold plant pots. a grp sheet with removable fixing can then ba attached to the outside

Basic fisrt attempt at a prototype Diy Sips (structual insulated panel) machine. It's using grp skin foam core  composite door off cuts as hinged holding panels

A Composite door edge off cut frame (2.1m long)  with 45degree off cut plastic corner braces is placed on top of  machine.

A plastic sheet & foil sheet would normally be placed underneath, But this pic is to show frame make up

Corners glued & screwed with a 70-8mm 5 torx swcrew & 55mm drywall screw
 

Plastic sheet placed on base to protect from foam leakage

Silver foil placed on top


 Frame placed, then  expanding foam sprayed in . For this experiment, I used 6 x foam cannisters, an expensive way of doing it (£18), but I am not in production yet, so not buying foam in bulk yet



 Foil is then plaed on top with shinier side on outside


 place plastic sheet on top of foil


Close top panel of machine press


6 cans of foam used (could of used 7-8, but was not sure of voume) temp was cold, so did not expand as much as hoped


Put heavy items to weigh top panel down, to counteract foam expansion pressure

Chat with the Reciproboo Inventor & Idea For Ladder Adaption

Last summer, I had a chat with Shaun Halbert, inventor of the Reciproboo structure frame, a beautifully simple concept.
 www.reciproboo.org/#/about/4591858953

Shaun was very helpful with an overview of the sector & some comments on my project.

I hav an idea fopr making a ladder to escape a flood etc, by adding a few  rungs. I also expreimented with different angles (see pics)

This was a rough idea, & not developed further, due to time constraints, but I love the design

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





Underside of thinner deck showing panel type construction

 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.

  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.
