https://africart.wordpress.com/023-joints

AfriCart – a handcart for Africa. ED302 – design and technology. 023 Research – Joints. Once I had decided to use wood to construct the cart I then needed to decide on a method of joining it together. Gluing would not be appropriate and neither would using nails or nuts and bolts and so traditional joinery was the solution I decided on. Practising Mortice and Tenon Joints and Drawboring. Tenon is shown flush with the face of the board (Mortice). Tenon is shown through the face of the board (Mortice).

AfriCart – a handcart for Africa. ED302 – design and technology. The AfriCart is designed to be built by ‘village’ carpenters with a minimal investment in commonly available carpenters tools. Any carpenter capable of producing a chair, table, or window frame can easily build an AfriCart, although it has been found that many village carpenters have difficulty following a (complex) dimensioned construction drawing. Not essential but a homemade equivalent would be very handy). Ruler / Tape Measure etc.

AfriCart – a handcart for Africa. ED302 – design and technology. 100 Further Development – Product enhancement. The AfriCart is designed as a “Push or Pull” cart, however it could also be easily reconfigured to be drawn by a Donkey or Goat. More accessible alternative to Donkey-Power is Goat-Power. Because of the AfriCart’s breadth, the unit could be one or two goat powered – further lightening the load for the transportation-short women and children of rural Africa. 8221; or “ The Gunners.

AfriCart – a handcart for Africa. ED302 – design and technology. 060 Production – Flowchart. Wood was selected from the wood store – two planks of pine. I first planed and edged these using the planer/thicknesser and then split them longitudinally using the table circular saw. From the wood room the wood was now transferred to the workshop – here the wood was planed to remove any coarse edges and cut into the carts constituent lengths:. Planks D were planed and then drilled to fit round cross-members.

AfriCart – a handcart for Africa. ED302 – design and technology. 022 Research – Wheels. When it came to choosing wheels for the africart three factors were considered: size, efficiency and availability. Size and Efficiency – Rolling resistance:. There are a number of variables that determine rolling resistance: tire tread, width, diameter, tire construction, tube type (if applicable), and pressure are all important. Smaller wheels, all else being equal, have higher rolling resistance. So from the above w...

AfriCart – a handcart for Africa. ED302 – design and technology. 021 Research – Materials. The choice of material is limited to what is suitable for use in the rural areas of SSA: suitability is judged on. Availability of skills and tools. If the material is hard to find in the rural areas and if it is hard to create sufficiently strong joints, it seems reasonable to assume that it will be hard to repair with any degree of longetivity, and so is no longer considered a suitable material. Many indigenous h...

AfriCart – a handcart for Africa. ED302 – design and technology. 010 Context Defining the problem. In Africa, the gender division of transport labour is particularly rigid when it comes to human porterage. Transport of goods by women is predominantly by head-loading, an effort which equates to the adult female carrying a 20kg load over a distance of 1.4-5.3 km every day.
