Re: [CAD_CAM_EDM_DRO] glass cutting lubrication

Hi,

The year before last I built a large glass-house in my back yard in the
Victorian Style. Most of the list will not know what this is as their
fore-fathers were still running round with fur hats and long guns. The whole
building consisted of small 12"x8" windows cut from 6'x3' sheet glass, about
a dozen of them.

I cut the first two sheets without lubrication and went through 5 wheels on
a cheap glass cutter. The hard part was to take off an inch, it went all
wavy and sometimes it was necessary to resort to snapping off little bits to
get it to size.

After speaking with a professional cutter I started using a very thin oil,
just dipping the cutter in it before each cut, and the difference was huge.
It is possible to hear the difference in the sound that the cutter makes
when you do a good cut and you know it will break cleanly. It did it every
time with the lube. It was even possible to remove 1/4" cleanly.

While it is possible to cut glass without lube I would always recommend that
it is used. You get a cleaner more consistent result and the cutter lasts, I
only used the one wheel to cut the rest of the sheets.
