Thanks Chris, put me on your list for a PCB design workshop. And thanks for the cutting tips. I have a carbide cutter for scoring tiles which I will try.
Also, I still have “at the back of the shed” a diamond tile saw that runs in a waterbath that I used for a large terracotta tile floor - but getting it out and filling it up and drying it out and putting it away etc etc is too much of a pain for just a few cuts!
Also I remember when vero was made with SRBP - synthetic resin bonded paper, which didn’t blunt tools. Regards, Miles
