Note: Huxley is optimized to be printed.
For the last two years I have been building various RepStrap versions of Darwin, Mendel trying to devise simple ways to build these printed self replicating machines. Huxley Seedling is based on all of the experience gained building the previous RepStraps. I built two of these RepStraps in February 2010 This will be the final rendition/ re-design.
This is the very First posting of all the components and drawings used to build a Huxley Seedling machine.
Note: Sebastien I have not blogged this design.. ;-) Nophead saw some of the early parts in February when we meet up.
Made the drawings for new Worm Extruder Drive MKV.
Made the component parts for Worm Extruder Drive MKV.
Build the Worm Extruder Drive MKV.
Test the Worm Extruder Drive MKV.
Learning to drive this wiki!
Lots of drawings and then draw all of them again as lost all of the previous drawings!!!!
Then re-making every part from those drawings might try other means to make from drawings.. Taking a trip into Manchester to FAB LAB MCR was very interesting and shaved at least a week off of drawing testing time.
Estimated total cost just below £200 in parts.
To do list
Documenting each stage
Photographing the build process.
Listing raw materials tools etc.
Spell checking every thing.
Low cost bearing solutions based on RepStrap Bertha builds alowing for upgrade to high quality linear bearings. We spent an interesting day at Fab Lab MCR  testing some of the drawings out using the Lazer cutter. Slight modifications are required to some of the drawings.
Sheet material MDF or Ply or Perspex/Acrlic or HDPE or Aluminum.
Fix It Blocks (a few)
M4 Screws Sizes/numbers to be defined not to far diffrent from the Mendel screws (not so many)
Steel bar or Stainless Steel Bar, Threded bar, Steel or plastic or Aluminum tube.
