I will keep you updated as I go.
This is a very experimental project.
The glass is only 19mm thick.
I will be grinding the back to almost the same profile as the front so the final mirror will be very thin, around 9.5mm
I will be using steel dumps epoxied to the pre generated tools for all the grinding.
I have to grind the mirrors circular first as they are around 1mm out of perfect circle.
The curve generation will be performed by a hanging pendulum grinder to get both mirrors to the same roc.
The mirrors will be set in dental stone so they dont rock on the back curve.
I may go with submerged grinding to get the best use of all the grit.
I have used all these methods in the past and they worked very well but this will be the first time they will all be used on the same mirrors in the hope I get two matched focal lengths.
Here is the flex output for what I hope to accomplish.
