3D Models
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.
