It is not as easy as you might think to drill a hole through three ceramic plates and add spacers. I drilled about 9 test holes before i did the real hole. I also watched 3 You Tube videos (can’t remember which ones so can’t leave a link sorry) and still i made lots of mistakes.
Tips: Don’t mark the centres of your plates with a big permanent ink texta, the ink will rub off with metho but i found it had also left a light permanent mark on my three Royal Doulton plates – most disappointing.
Tape a block of wood under the plate, seems to mean the ceramics chip less.
Keep the drill bit wet.
Every plate is different, old english china drills a treat, the new stuff us very tough to get started through.
Challenging project, enjoyed it but a tonne of work getting it just right.
