  1. Manufacturing Plan

  2. Methods for building in the Innovation Space with limited power tools and skill sets

  3. Mortise and tenonjoint (top right picture ‘A’) • Tenon – rectangular protrusion from the male joint • Mortise – female joint with a square opening • Measure and mark the tenon; use the saw and chisel to cut • On the female joint, measure and mark where the mortise will be • With the largest drill bit, drill through the center of the mortise square and use a chisel to square the rest of the piece • Fit the tenon in the mortise; drill a hole for the dowel on the protruding portion of the tenon • Hammer the dowel the hole to secure the tenon in place

  4. Sliding Dovetail joint (top right picture ‘B’) • Mark and measure the dovetail; a taper of 3-5 degrees is recommended • Cute the dovetail and sand it until the edges are rounded and smooth • To cute the dovetail groove, clamp the dovetail to the female joining piece and use it as a guide for the saw; cut • Chisel the groove and sand until the dovetail fits securely

  5. Dado Joint (top right picture ‘C’) • Measure and draw the groove cut length wise on the mating piece • Cut each side of the groove ¼- 1/2 inch down • Use a hammer and chissel to remove the wood for the groove • Hammer the joining piece in place

  6. 2. Dowel Joint (top right picture ‘D’) • Measure and draw the spacing for the dowels on both pieces that are to be joined • Drill half the length of the dowel down on each side • Hammer the dowel into the holes on one piece • Match up with the joining parts holes, hammer in place

  7. 1. The first step is to apply the primer to the fitting and pipe ends. The PVC Primer will soften and prepare the PVC Fitting or PVC pipe length for the cement that will be used when connecting.

  8. 2. Next, choosing the cement may be the most important step in the process. Before applying the cement, you need to stir it well.

  9. 2. After stirring, liberally apply it to both the pipe end and fitting socket. Add one more layer of cement to the pipe end, and then quickly assemble the fitting and pipe, ensuring a full and complete connection. Finally, wipe away the excess and let it dry

  10. Identify nodes – thick rings; these are needed for both ends of the joints or else the bamboo will splinter bamboo joint node

  11. Similar to tube fitting (this bicycle frames), bamboo joint cuts have a male cut that fits into a female groove on the connecting piece bamboo male cuts

  12. Cord or a dowel system (above left inset) can be used to secure the joint; wood nails will splinter the bamboo Securing a bamboo joint

  13. NCIIA Cameroon Project Leslie Speer, San Jose University "Reverse Engineering Bicycles to Develop New Businesses, Products and Increased Income for the Metalworking and Agriculture Industries in Lebialem (Cameroon)".

  14. 1. Cut shapes out of sheet metal with metal sheers and punches (drawings can be found at http://cameroonprojectnciia.blogspot.com/ ) 2. Hammer sheet metal to shape of connector

  15. Methods and options for connecting similar materials, mixed materials and hardware to projects in the Innovation Space

  16. Simple Structures • Mud bricks shaped with wooden molds • Dries in the Sun • Clay+Straw+Water (simple materials)

  17. Straw Bale Straw and soil mortar Sand and cement mixture

  18. Straw bale Connection Blocks Pinned together Attach around secured pole

  19. Woodworking: Pegs Uses: Furniture Vehicles Small Structures

  20. Metal Joints: TrussesMetal->Wood connections

  21. Simple Mechanisms: Materials to Material C-Clamp Tie-Wrap

  22. “Usables”: Materials to Hardware Bolt and Lock Nut Casters Non-swivel wheels can attach using a bolt, spacer and lock nut assembly. Casters have four pre-drilled holes around it’s top support. They can easily attach to a flat surface using bolts and nuts.

  23. “Usables”: Materials to Hardware Surface Mount Hinge Mortise Mount Hinge Attached to the door or frame; uses screws to secure Mounted into recessed cutouts (mortises) on door's edge; uses screws to attach

  24. “Usables”: Materials to Hardware Eyebolts to Hooks Eyelbolt to Rope An eye bolt screw could provide an easy connection to a carabineer style hook for a removable item, such as a bag that fits into a cart or to secure an item onto a cart A simple way to secure items on a cart would be to attach an eye bolt to the frame of the cart in appropriate locations and use rope to secure it in place
