I made up another 'window' blank last night (with clear acrylic rod inserted crosswise prior to drilling) and mounted it on the lathe for drilling. I had decided to start with a smaller diameter bit (9mm), then pulled the tailstock back and swapped for the 11mm bit. Pushed the tailstock forward towards the blank and - BANG! I had forgotten to switch off the lathe, and the drillbit just blew the front half of the blank apart ...
... So I called it a night and went inside for a whiskey.
