My first go at a bin cage, I used a razor blade knife, heated it with a flame, cut a little, and the repeated. Oh what tedious work...AND a part of my middle finger was numb for a day afterwords from all the pressure I was using!
So I had to do something different on Dawin's new bin cage because it was much bigger and longer than the first. We have a Black & Decker drill that has interchangeable heads (a drill, a grinder, a sander, etc) and I had used the grinder part before to make the edges of the mesh smooth. Well, turns out that the grinder works VERY well for cutting through/melting the plastic bin too
So I used that to cut out all the windows in the bin (I'm sure it's probably not good for the grinding plate, but it worked wonders)! And no numb fingers! Lol
