Frequently Asked
Questions
(Epilog)
Q:
Why, on the Rotary Glass
Attachment, is my text/logo coming out stretched or condensed?
A:
Setting
up cylindrical objects with balloon or tapered shapes.
1. Measure the circumference
of the
object at the point of rotation.
2. Measure the circumference at the point of engraving.
3. Divide the point of rotation by the point of engraving.
4. Stretch (or compress) the text by the result of the equation
above.
Examples:
Tapered Shape
4” at lip of the glass (driver motor point)
3” at engraving point
4” / 3” = 1.33”: Stretch the text to 133% of its original size to maintain
the aspect
Ratio.
Balloon Shape
3” at lip (driver motor point)
4” at engraving point
3" / 4" = .75: Compress the text to 75% of its original size to maintain the
aspect ratio.
Q: When I engrave glass, the
engraving feels rough. Any tips?
A: Lay wet newspaper
over glass before lasering. This will dissipate the heat and the engraving
will feel smoother.
Q:
How do I engrave a glass where the handle is too close to the top, like a
coffee mug?
A:
Remove the extra wheels from the attachment by taking out the black thumbscrews
inside the wheels.
