  •   I like this tool.
By on
Pros : Enables quick and easy drilling of holes.
Cons : Can get jammed up with the glass plug it drills out. This creates a surface at the drill tip that blocks the tip of the drill from cutting into the glass.
Other Thoughts : I clean out the shaft chamber after each drill. A small piece of wire pushed down from the side opening should push the core of glass out the tip.

  •   Broke Off
By on
Pros : makes neat holes easily.
Cons : it snapped in two in the glass after little use. doesn't seem like a good value if breaks so quickly and easily. Too expensive for that result.
Other Thoughts : i am buying another one to give it another try.

  •   Long Life / Smooth Cut / Great for Glass
By on
Pros : This bit worked great with my flexshaft drill and fits the with my dremel as well. It makes a nice, smooth hole, even as the bit begins to dull. I was able to make over 30 1/8" holes in 3 mm glass per bit using water as a lubricant. I've tried other bits that haven't been able to handle the load of these bits. This is the only one I'll spend money on. Well worth every cent.
Cons : Would like to be able to get a quantity discount on these bit.

No oneknowstheexactorigins of glass fusing although there is evidence that the Egyptians were familiar withrudimentary techniques. The Romans however arenoted by scholars for developingrefined glass fusing skills. Although technology has changed the way modern glass fuserswork,the technique isessentially the same as those developed by the Romans centuries ago. The basic technique involvesstacking two or morelayers of fusible glass, which are then placed in a kiln and gradually heated to between 1450-1500 Fahrenheit.At these temperatures the layers of glass fuse, or melt together and become one. Unfortunately, glass kilnsare large andexpensive,whichkeeps most Hobbyists from pursuing this art form. Now there are new kiln options, including theThe Fuseworks Microwave Kiln. This device works in most household microwaves and can fuse glass in about 3 minutes. Here are some common questions we get on fusing in this modern-day kiln. The following are Q A complied by Diamond Tech, the manufacturer of Fuseworks

Can you please tell me the correct way to mitre the lead for diamonds? Diamonds can be tricky. This diagram shows the way we would go about cutting the lead for a diamond. We find the easiest way to decide where to mitre the lead is by drawing lines on the diamond connecting the opposite points. Then, put a piece of lead on the glass and extend that line onto the lead. Now remove the lead and cut it where you marked. Replace it on the glass, lining it up where it belongs and mark the other end of that piece of lead. Cut it, replace it, and continue until all of the pieces of lead are cut. Reprinted with permission from Stained Glass News. All rights reserved.
