Drilling plexiglass

Hi all. I've wasted 2 sheets of plexiglass so far as I'm trying to make an overlay for my control panel - some of the drilled holes are off a few mm, which results in the button not being able to go in. Correcting it I can make the hole larger but then the button doesn't cover the entire hole.

I'm using a forstener bit. I assume the best method is putting the control panel on top of the plexiglass, clamping both down and then drill - make the holes like that yes?

Use your panel as a drilling template and clamp plexi between drilled panel and scrap piece of wood.


good day.

I ended up drilling pilot holes using the slag-coin printouts as templates.  I put a light under the CP, centered the template over the hole then drilled a center pilot hole in the dot. 

It worked, all of my buttons fit with no added effort.  If it's only off a hairline you could probably widen it just enough with something like a chainsaw file, and still not see the fix.  I'm pretty sure I've accidentally drilled 1 1/4 holes and still been able to use buttons without seeing much gap.  Of course if you are using LEDs, you'll want to just bite the bullet until you get it right.

I clamp the plexi to the panel, then use a dremel to punch and cut out the hole.

best way is to use a router...a  V groove bit to plunge into the plexi to make pilot holes, then a flush trim bit to finish them. works great and doesnt crack....also, everything lines up perfectly with the wood
