Graflex clamps. How were (are) they made?

I asked Hydin if he could have some made out of crystal - but no go.

This was discussed years ago, and it would just be too costly from the get go. granted it would be the coolest part of the lightsaber though.

To me, it would have to say Graflex on the clamp. They arent that hard to make from scratch, but I would want an accurate one if needed.
