a friend kindly said he could supply a sheet of playfield glass for my dear old black rose machine, as his friend was a glazier, great I thought I gave him standard bally dimensions but sadly instead of being near 5mm he’s cut it from 6 my glass and it only fits half way up the table. I know I don’t reallg have any come back as it’s a mate doing a favour so has anyone got any tips on getting a slightly thick bit of glass in the slot ?
