Making wonderful glass mosaic tile art is easy! Permit me demonstrate how.
Wheeled glass cutters are essential for creating glass mosaics. I use it to cut and condition vitreous a glass and stained glass. This can also be used to slice smalti. The wheeled cutters make cleaner cuts than tile nippers. The two carbide wheels (or steel, if you buy cheap cutters) are fixed in position. Rather than scoring and breaking, the wheels apply even pressure to the top and bottom edges of the glass, leading to it to fracture together the line of the wheels.
The wheels are replaceable and eventually go dull, however, not before several thousand cuts. Each steering wheel is held in place by a setscrew (usually an Allen screw). As your cuts become significantly less clean than when the cutters were new, use an Allen wrench tool to loosen the screws, rotate each wheel about 1/8-inch, that is and then re-tighten the screws. By altering the location of where each wheel touches the glass, you have, in effect, replaced the cutting blades. It'll require a long time and many cuts to use the entire circumference of the wheels, particularly when they may carbide.
When the wheels finally do become boring, I suggest buying a entire new tool. The wheels make up the bulk of the tool's cost, therefore you won't save much by just buying replacement wheels. With a brand new tool, not only are the tires sharp, nevertheless the rubber handle grips are new and clean (the rubber would wear down and becomes dirty) and the spring is secured in-place. Every now and then, the spring breaks free from my cutters. The tool still works with a free spring, but annoying to keep the handles from spreading too far aside. When that happens, the spring falls off. It's quite annoying to decline the spring, watch it bounce out of reach, and then have to get out of my chair to retrieve it. I tried soldering it permanently in place, but it didn't work because I couldn't get the metal hot enough. So, until I buy a new tool, the spring constantly falls off. Another reason to get a new tool as opposed to just replacement wheels is, if you drop the tool, it's possible to knock the rims out of alignment. Therefore , after several projects when you think the rims need replacing, I suggest buying a whole new tool.
Whenever your new tool arrives, how to use Allen wrench tool to tighten the screws as tight as possible. Then, use an engraver, paint, felt-tip marker (or whatever you have that makes a permanent mark) to make a small beat mark privately of each wheel where it variations the glass when slicing (the two tick signifies should be aligned opposite each other). I use an engraving tool in making the tick marks therefore i don't have to worry about paint or ink eventually rubbing off. After a few hundred cuts, release the screws, turn each wheel slightly, and then re tighten the anchoring screws. After several of these adjustments, the tick signifies have hot full circle indicating that it's time to replace the tool (or just the wheels, if you prefer).
Don't be surprised if the rims rotate by themselves. No matter how hard I crank down on those anchoring screws, it apparently isn't tight enough because the rims slowly rotate by on their own from the pressure exerted during the cutting action. Right after several days and many cuts, I spot the mark marks are no extended aligned directly opposite each other, signifies the rims have rotated slightly. Might be I'm a weakling, but I just can't get the screws tight enough to keep them static. However , that's okay with me because, if they turn by themselves, then I don't have to by hand do it.
