OK, I'm going to look into this too for fun. I think clear/colorless scales would be wicked. :D
Major issues I'm seeing right now are a) what to make the wedge out of that won't look ugly with clear glass, will adhere to the glass, and will provide some strength and/or cushion, and b) how to assemble the pins. I'm thinking, from the outside of the razor in:
pin
plastic washer
silicone?
glass scale
silicone
plastic washer
blade
...and then repeat for the other side. But where to obtain such pieces? And who can I convince to assemble this thing for me? Hmm... :hmmm:
