Barbara,

That's so cool about the numbers! I thought it had something to do with the angle of the score. Glad I asked. Are there printed directions for this gizmo anywhere? Thanks for the specific info about hwo to run the score. That makes sense.

I am hitting wall with this one though:

cut some relief scores from the circle line to exact cut line border of the glass, about 8 is a good number.

BTW Not to long of an answer. Thanks! - Linda

One more thing - Does it matter how much bigger the square in which the circle is inscribed is from the circle? In other words, if I'm cutting an 8" circle should the square I cut it from be 8", 9", 10" or bigger? Or maybe it doesn't matter

Here's a way to cut circles.
Cut a square 1" bigger than your desired circle.
Apply the circle cutter and score.
Cut off the triangular corners leaving a 1/2" border.
You should now have a rough circle still 1" bigger than desired with the correct circle scored within it.
Run the score with breaking pliers.
It usually isn't even necessary for relief scores, the rim will break into 2 or more pieces.

Sorry....that is too much waste for me especially when you are making large rounds. I maybe leave 1/8" extra and no problems here!

I'll get back to you with my very good reasons in about 51 months . . .

Here is another description of cutting out a circle:

First, score the circle, making sure that you start and stop the score line at the same point.

Turn the glass over onto a piece of corrugated cardboard, or other surface with some give, with the score line face down. With your thumbs, press along the score line until you see the score line "run" progressively and completely around the circle. This prevents the relief scores you are going to make from running through the circle.

Turn the glass back over to the side on which you scored it. Score several lines perpendicular to the circle to the corners of the piece of glass. Gently open these scores by tapping with the ball of your cutter, or with your hands, pliers, or other tools. The the pieces should fall cleanly from the circle leaving you with no rough or jagged edges.

Hi Laurie,

are you cutting the circles with only 1/8" extra from Sys 96 or BE?

I use BE, but have had the opportunity to use 96 in a workshop, and thought that the very smooth surfaces make it easier to cut circles. However, my experience is limited.

Thanks and best regards, seachange

Both.....we use it all. Spectrum is extra easy. Just be sure you cutter has a good blade. We maybe get 30-40 18" rounds and then change the blade.

Wasn't this question asked in 2008?

Hence the reference to 51 months . . .

I got your 51 months comment immediately Brock !
When I first started reading the board there were "posters" that I realized right away, knew what they were talking about....one of them being you.
I have my very own "Brock Binder" that is filled with information and schedules. Priceless !
It is just as useful to me as Stone's firing schedules. Thank you for all your years of posting and sharing !

Thank you Gail. Being compared to Graham Stone is an honour. Undeserved, but an honour.

Wrong...it IS deserved !

I have to agree with Gail, I don't own the book, what I have learned is from my own testing and being a follower on this site. I have no Idea of who Graham Stone is except for what I've read here but I can say I have learned a lot from many members on this board, so Brock, That was a well deserved compliment.

There is a video of Patty Gray cutting circles on the Spectrum website. It is very well done.
