The method is to calculate the size by taking the diameter of the cylinder and divide by 25. This gives the width and the thickness. These are then cut to split them and in my case I used a Jeweller's saw with a blade thinner than 0.2mm which gives minimum loss. Apparently, the secret is in the heat treatment which is also the problem as the ...Web
