The grooves on a glass cutter are used for controlled breaking of the score

[석수]

The grooves on a glass cutter, typically near the cutting wheel, are used for controlled breaking of the scored glass, especially for smaller pieces or tight curves.

These grooves help to initiate and guide the break along the score line. Some grooves are designed for specific glass thicknesses.



How To Cut A Tight Curve In Stained Glass

This technique works with tight curves.

These are pieces of glass where the curve is radical enough that the tips of the glass break off using conventional methods.


The idea is to take several small cuts so that the entire piece isn't being taken out all at once.

Start by scoring the glass on the inside of the curve, just like you would do on an easy curve.


Then score the glass several more times so that there are several scores inside the curve.

Using two pairs of grozing pliers, hold the glass you want to keep firmly with one plier and grip the outermost piece of glass with the other plier.

Rock your pliers down and out slightly. Don't try to crush the glass, just put pressure on the pliers, pulling the pieces down and out and wait for the glass to give way.

Then go to the next small piece of glass and break it out using the same method.

Keep whittling away until all the glass pieces are removed.

Finally, you'll have a tight curve that can be ground to fit in your window. And no broken tips!

scored glass

The grooves on a glass cutter, typically near the cutting wheel, are used for controlled breaking of the scored glass, especially for smaller pieces or tight curves. These grooves help to initiate and guide the break along the score line. Some grooves are designed for specific glass thicknesses.

Here's a more detailed explanation:

Scoring:

A glass cutter creates a shallow score or groove on the glass surface.

Breaking:

The grooves on the cutter help to initiate the break along the scored line, especially on smaller pieces or when making curves.

Controlled Break:

Applying pressure on either side of the score line, sometimes with the help of the grooves, encourages the glass to break cleanly along the intended path.

Specific Groove Sizes:

Some grooves are designed to accommodate specific glass thicknesses, making the breaking process more efficient.

Beyond Breaking:

Some specialized tools, like groove glass grinder bits, use grooves for shaping and grinding the edges of glass pieces.
