Introduction
This page is dedicated to visual and performance modeling of the Liberator, OSE's open source, high-performance CEB press.
Finite Element Analysis
Calculation Symmetry
Bolt Strength
Bolt torquing can be measured by a torque wrench:
Starting to create the 3D model from previous sketches provided. We should take a look at using square washers on the back of the channels, they help to apply the forces evenly on the bolts and structure.
- Where do I get these washers? Do they have ones that match the slope of the u-channel, or must I obtain them by cutting up another piece of u-channel?
Marcin, I see from the video that you provided that you have modified the chamber to use a 1/4 plate on the side. What was your reasoning?
- The top part of chamber is u-channel because it requires the strength. The bottom doesn't require the strength - as it is only the beginning of the compression stroke. Moreover, it needs to be longer so that it encloses the entire compression plate assembly.
