What is the best way to drill 2-1/2″ holes in the sides of 8″ square glass block?

I would like to run 3/8″ rope lights through the middle of glass block

drilling is impossible at this size.What you ask to do is best left for the extreme artist’s that sacrafice all in the name of progress. Some have developed ways to perhaps meet your expectations.Be assured that none will divulge there secrets of success! Untill you can leapover whatever they have experienced-you will have no respect among a single one of them. Welcome to the world of self-sacrafice, at the most extreme!

2 1/2″ holes are possible, but to get that type of hole you will need some seriously specialized equipment. CRL (CR Larwrence) is a supplier of glass cutting & fabricating tools. They will have what you need but plan on shelling out the $$$. The best answer would be asking a larger glass company in your area what they would charge to do it. You might want to consider going with square notches vs. round holes due to the size. Square holes would be easier to to do.
