How to cut Plexiglas (Acrylic sheets)
Plexiglass / acrylic plastic sheets is a great material when building robots.
If you are having electronics and mecanics on each side of something, and want to pack cables, motors, sensors etc in a tight space, it is great to be able to look through your "base".
It is so much easier just to look where to drill than measuring etc.
Double-adhesive tape glues extremely well to this, and it is nice plane etc..
BUT! It is impossible to cut.
You should think it is easy, but it is not.
Either you crack it, or the wierdest thing happen; Just behind your blade, it melts back together.
I did not believe this was a problem untill I saw it with my own eyes.
If you look at the web (as this was not) - you find thousands of strange advice; Put spirit on the blade, go slowly, go fast, use fine tooth, use rough blades.. And I have tried it all and was about to give up.. untill i found this:
There are special blades for jig saws, made to cut acryllic. And they WORK! That´s it! :)
Transparency can be a bliss :)
