Many thanks @rustyfundi! That means we're covered for the frame, we've got a rough cost of the motor down to ~35,000 KSh, and I hear the laser cutting of the stainless steel is coming to ~35,000 as well. Add the electronics and other incidentals, and we're looking at a total cost of ~100,000 KSh?
Unfortunately, this does seem to match what I've found digging deeper into the Precious Plastic project details. The rough costings provided with the videos don't seem to match reality. Most people on this thread say their build has ran from 700 - 1000 Euros:
I think we can definitely get those costs down if we reconsider some crucial elements of the design:
- Reusing one motor to power multiple machines
- Using a smaller motor, depending on the type of plastic we want to be able to shred
- Using mild steel instead of stainless steel for the shredder knives
There's a lot to reconsider here, so I think our next meeting (on the 17th) will need to be more of a design discussion than actually building the thing.
