wrote: Hi. I am building an amp and will be using a clear plastic over the front panel graphics. I could use some help in choosing the material, such as Plexi or Lexan. Since I will be drilling couple of 2" holes to mount panel meters, I need some suggestions for which material is the best to work with. A hole saw in Plexi is prone to crack and maybe there is a better choice. There also may be a better method for creating the holes than a standard hole saw. Suggestions??? de Rick W1TY Email: 2 thoughts 1. If you decide to use the plastic water with a bit of detergent makes a good coolant/lubricant. Keep the cut flooded. 2. I made a lot of panel covers inthe past by laying out the panel in Autocad then flipping the drawing layer with the graphics on it to get a reverse image. I then made an overhead transparency of the graphics and used the transparency over the metal panel. The result was a clear plastic cover with the printing sandwiched against the metal panel. It worked quite nicely. You might want to consider it. |
