As Paden and I sat down and brainstormed about the ideas that we wanted to implement throughout the course of the semester, several approaches are thought to be made. Of the ideas that we came up with, here are the top 4 that we would like to try as the semester continues.
1) Grinding Stone
For this idea, we looked online and found a grinding stone that had 8 different types of groves in it, all ranging in sizes and shape. The idea is to use a groove similar to the shape we want in the bevel and grind the lens with the stone until it reaches the desired shape. This idea stemmed from the work that Paden had done in beveling the lens by hand, using sand paper, which allowed it to fit inside a frame.
2) Grinding Block
Very similar to the grinding stone, the grinding block is something that we could create while the grinding stone is being shipped. Basically, for this idea, we would cut a piece of wood so that it has a v-cut shape in the middle of it, and attach sand paper to it so that it can also sand/grind a bevel on a lens.
3) Double Angled Bevel Tool
For this idea, we were planning on grinding two cylindrical bevel bits at an angle and then attaching them together so that they form a v-cut type angle. Once this bit is created, we are planning on creating another machine, or simply another type of set-up so that the lens would fit in between this angle, and would grind a bevel into the lens.
4) Grinding Wheel
This idea is somewhat of our last approach due to cost and other building issues. Similar to how doctors bevel lenses now, if nothing else works, we are hoping to purchase a v-cut grinding wheel and create a bevel by attaching the wheel to a rotary machine, and then beveling the lens by hand.
