Problem Slicing Pattern Bar

Post by Melissa Terman »

As I'm slicing through a pattern bar, when I get to the very end of the slice it cleaves and ruins the cut (and my need for perfection). I'm slicing on a MK 101. The water feed is working and everything appears fine, until I get to the very end and snap.

Your input is greatly appreciated.

Melissa,

As you get very close to the end of the cut, the glass becomes very thin and will snap with the slightest force. So, when you get close to the end of the cut, slow way down and don't push so hard. Let the blade grind its way through the last bit of glass.

Melissa, along with going more slowly yo can also try to increase the thickness of your slices a bit. I find that the thicker the slices, the less breakage I have.

I'm having trouble visualizing this, can you try to explain it better.

Can you cut a short way into the far side of the bar, then flip it and make the main cut? I haven't cut pattern bars, but I've used this method with wood and with single-thickness glass to prevent breakout.

I have found that the best way for me, is to back the pattern bar with another piece of glass or ceramic.javascript:emoticon(':idea:')
