The third tile tool for fine grinding


On the curved rough ground surface I put a border for casting (diameter 400mm) There was a protective layer of plastic on glass. Before casting it is important to check that everything is levelled so that the disk will have constant thickness.


Now the plaster is cast. Note that I protected the mirror with plastic.


This time I used glass tiles instead of ceramic ones. These tiles are softer and suit better for fine grinding.


Glass tiles glued on the tool with epoxy resin.


Close up look!
