The AMP makers collective has run over 35 workshops to date around the theme of transforming the Agbogbloshie scrap and recycling ecosystem into a network for distributed manufacturing and digital fabrication.

Here is a list of the main events held as part of the AMP series of informal maker workshops to build the future of Agbogbloshie:

Makers and Development

1_M&D Logo

M&D derives as a term from a series of design research seminars conducted at l’École Spéciale d’Architecture (2013-2015), which opened students to participation in a group project to challenge the consequences of technological dependence by remaking Agbogbloshie T.A.Z. conceptually: proposing tools to better equip the dynamic territory that operates outside the bounds, hosting technology’s unmaking and reconstitution. Spaces of unmaking inherently anticipate spaces of remaking; in Agbogbloshie at the end and restart of product life cycles the mantra reduce, re-use, repair, recycle forges its own logic. M&D operates via emphasis on making: each loop of conceptual iteration necessitates another prototype, so participants inherently discover knowledge through the making process. In the case of AMP, the community of makers includes a diverse collection of individuals working not only in Agbogbloshie (e.g. computer repair and refurbishment workshops, small-scale aluminum smelters) but also situated adjacent in the Accra Timber Market (e.g. the carpentry, metalworking, tinsmithy and equipment manufacturers) and distributed further afield (roadside electronics repairers, mechanics, welders, glaziers, furniture craftsmen, seamstresses and tailors city-wide) who make and repair items for a living.

Spacecraft . 2d truss jig

Mild steel angle bar is liable to twist or bend before the truss is triangulated; to ensure that each octet truss you make is straight (±1 mm) use a straight and square metal jig with wood board forming welding bed (will burn over time, flip over before replacing). Use clamps to secure 2d truss frame to jig, and push metal against wood plate of jig with a nonconductive pipe or wood stick.

Welding: Tack weld first throughout to assemble octet truss, then complete full weld once all metal elements are held in contact. Usually a small amount of grinding required to clear sharp edges. Apply hardener coat to seal and spray 3-6 coats of automotive paint. Paint damage possible (e.g. scratches) during transport and assembly; paint touch-up work may be done after assembly.

Octet truss drill template

Use a template for drilling holes in octet truss, to ensure that all holes are the same and identically located. Print on paper first,then trace or laminate onto cardboard and punch hole centers per template guides. Provided octet truss welding work is standard, dimensional tolerance of ±1 mm is achievable. Square face bolted connection is 20×20 cm, with holes of sufficient tolerance for no. 17 bolts.

Spacecraft . octet truss fabrication process

Fabrication of a semi-octet truss using 1 or 1-1/2 inch mild steel angle bar requires use of several jigs: 2d truss jigsquare pyramid jig, and spacers for setting flat bar and holding string line to gauge top angle bar when welding. Each truss comprises 16 square pyramids of 4 pcs 10 or 12 mm by 16.85 cm iron rods welded to a linear array of 19.6 cm flat bar straps set in a 1 or 1-1/2 inch ms angle bar frame 20 cm wide by 282.5 cm long.

Welding: Tack weld first throughout to assemble octet truss, then complete full weld once all metal elements are held in contact. Usually a small amount of grinding required to clear sharp edges. Apply hardener coat to seal and spray 3-6 coats of automotive paint. Paint damage possible (e.g. scratches) during transport and assembly; paint touch-up work may be done after assembly.
