(first of all, I know this is quite an old post, but I wanted to give my 2 cents here for people who land here for the same issue)
Like you guys, in the past, I’ve also been thinking quite too much “into” the box, rather as thinking “outside” of it.
So, now, thinking outside of the box, let me say this: just use a normal sinkhole drill, the one you can buy at your local DIY shop, the one you use just to drill sinkholes in your wood. It will work perfectly on wood, plexiglass, and acrylic material.
And now I’m thinking that perhaps you guys were thinking out of the box, and I was just plain and simply thinking inside of the box all along. Oh well, let me just grab another beer and forget all about this
Don’t hesitate to let me know how you think about this.
