Maybe try another mock up to see how a full length one looks?

I have worked with tiles so I know patience is key - Nothing like nibbling a tile for 15 minutes only for it to crack at the last second.

Also I drilled very slowly and did it in the back yard with the garden hose running cold water over the hole saw - I drilled quite slow each hole took about 5 minutes.
