Acrylic drilling help

Pages: << < (3/5) > >>

Franco B:

If you have a router and a flush trim bit I would drill a small hole for the router bit and then route them.

The metal CP won't be thick enough for you to run the flush trim bit along so what I do is stick some ~1"x2" pieces of 1/4" acrylic using double sided tape to the metal CP, then use more double sided tape to stick the acrylic sheet to the acrylic pieces.

This will raise the height of the part that you wish to copy which will then allow the bearing to run along it whilst the bit cuts the acrylic.

I actually need to do a similar job tomorrow if you would like me to take some photos.

Lots of good advice here. I made a video a while back...

I find that it cracks mostly because when the drill bit gets through it starts to lift the plastic upwards and THAT causes the crack.  What you have to do is make absolutely sure that does not happen.  I usually clamp the plastic between two pieces of wood so that no part of the plastic can be raised during the drilling process.  If I don't have wood pieces to sacrifice I will put three clamps right next to the spot to be drilled.  Anything you can do to prevent that plastic from getting pulled up by the drill bit will likely prevent the cracking.
