Fabrication Ergonomics Continued

Here we continue to document the fabrication ergonomics from where we left off on the Compressed Eearth Brick (CEB) press.

Transfer punch and drill holes for frame – 3 hours. Mount the arms – 1.5 hours. Build soil-loading drawer – 3 hours. Build hopper interface plate and hopper – 4 hours. Mount main cylinder – 2 hours, build hopper shaker – 1 hour. Install grate – 2 hours.  Mount shaker – 1 hour. That’s about all for the main parts of the CEB press, minus some details. Click on the images to enlarge. The metal cut list was shown here. Next come the automatic control electronics with the Arduino microcontroller and Hall effect sensors as described in this working paper.
