Hopper Work Statement
Chuck,
I have pictures of modified fab drawings for the hopper and other sheet steel up at
Let me know if you have time to work on any of this to produce any of the drawings by midnight, this Wednesday. We need to generate DXF for CNC torch table. Best packing from 4x8 and 5x10 sheets should be sought.
If we have this by Wed., we can test these on CNC lasers and routers. Otherwise, we can spend until Dec. 10 to generate the DXFs.
If so, we need to secure a CNC torch service that can do it within a week turnaround.
What file formats are acceptable to CNC Torch operators?
If you have time, please let me know what you can do on this so that I can manage completion by allocating appropriate resources. I will ask for help from others, and if I find none, then I will complete the DXFs myself. Unfortunately, we do not have access to a version of Solidworks compatible with the original CAD files, which are found on the wiki at http://opensourceecology.org/wiki/CEB_Press#Mechanical
On this tight schedule, manual generation of DXFs from existing fab drawings is the quickest route, unless someone can generate updated complete 3D CAD. We do not have that capacity off hand.
For the hopper, one could take the original Solidworks and update the hopper. The interface of the hopper to the frame and supports is identical, though the grate attachment has a slight modification.
