I'm still robbing my museum...

And I need to cut glass. Or my characters do. I've found this glass cutter that will work really well for my purposes (can cut the right thickness of glass). It's called the Toyo "Tap Wheel" Thick Glass Cutter. I won't refer to it as that in my book (it won't have a name) but that's what it is.

Problem is, I can't find any information on whether or not that specific cutter needs oil put directly on the glass to operate. Any glass cutting experts out there with ideas?

thanks for helping me with my oh so illegal adventures
