Good video. That is very thin plastic and he's burning rather than cutting through it. He was drilling into the side of it and I could tell it would be easy to place a block of wood inside it. Keep the wood tight to the cutting surface and that would go a looooong way making it easier to drill. The plastic could not flex causing binding of the blade. Find a finer tooth saw than what he has. Even if you spent 50 bucks on a diamond hole saw, it would be cheaper by far than any press. Keep the surface wet for an even better cut. BTW, thanks again for your suggestions on the other thread.
Yeah the acrylic boxes are thin. OH really, more melting it than cutting it, interesting. You recommend a block of wood to make it easier, how does it make it easier? I read that elsewhere on a home site, but the writer didn't say why haha. Is it to minimize the flexing of the acrylic and thus cracking due to the binding you mentioned? That's the only thing I can think of. I've only drilled holes in wood, with normal bits, so a bit out of my comfort zone in this project haha, despite how simple it is. Plus, I hate breaking non-scrap materials that I bought.

The tough part will be finding a diamond hole saw with small teeth, that way it doesn't rip the plastic. The Milwaukee ones I saw recently seem to have large teeth for the type of task I want the tool to do.

This is what I saw (not including the bit) http://www.homedepot.com/p/Milwaukee-2-in-Bi-Metal-Hole-Saw-49-56-9624/202327750#specifications

In keeping it wet, I learned that's to reduce the heat due to friction and thus melting of the acrylic (you can see melting in his video, no big deal there). What liquids would you recommend, would water be good enough?

I saw some diamond hole saws last night. I will check them out before I buy and probably relay what I learned here or PM you.


You are quite welcome on the other post. That's why we are here, to help each other. Which reminds me...there's another forum you should check out for ideas on canopies. Head over to the dendroboard.com It's a very large tree frog community. The owners there build far more elaborate vivariums for tree frogs, usually dart frogs, than I have found on this forum. Those people build a lot canopies for their lights, fans etc. Off the top of my head, there are 2 guys I can think which have done some building. One guy did a great build for a large T. blondi tarantula, which included a misting system. I'm fairly sure he can offer you some pointers as he offered to me.

And, there's another guy who has a long thread for his vivarium build on here, including computer fans in the canopy. I can't remember either screen name. I need to find them and PM you.

harbor freight...picked up a drill press for $50 bucks, $11 for a 2" forstner bit... and these are the holes it made...super clean..(used a baking soda water mix to prevent heat build up & the fuzzies are the other side of the paper...)

now to figure out a way to make a stable "mitre" type box to cement it together. (3 sided box to square up your acrylic)

Baking soda? Hmm..how does that help prevent heat build up..interesting...What was the "mix" made of, the proportions etc.??

Haven't tried that yet. But I did use 50:50 Palmolive/Water - worked perfect for small Acrylic boxes. No more melted plastic on the bit!
