Hello, I purchased an acrylic case. I noticed that to screw down the cdrom drive or floppy drive on the right side of it, there is no access to it without removing the mother board. Are there any suggestions in creating perhaps easy access to the cdrom drive or floppy? What could be used to drill holes or to cut acrylic cases for modifications? Thank you
I wouldn't worry about it, just screw down one side.
A high-speed twist drill (the same as you would use to drill a hole in metal) is fine for plastics, including acrylic. For cutting larger holes, you can use a holesaw, junior hacksaw or power jigsaw (there are special plastic cutting blades available, otherwise use a metal cutting blade). Dremels might be OK, but I'm not certain if the high speed of the bit would cause the plastic to melt, perhaps someone else will know for sure.
In my experience anything that is OK for metal cutting is good for plastics too, as a rough rule of thumb.
I can attest from experience that a Dremel cutting disk tends to melt through acrylic than cut it if you aren't careful and patient. I can only guess that a high-speed drill would do the same (maybe depending on the diameter). I would go slow on the drilling also...might get a cleaner hole that way.
Oops, I should clarify what I meant by high-speed twist drill. I meant one that is made out of high-speed steel, not one that is used at high speed. As bistro so rightly says, slow and easy is best when working with plastics.
Thank you supersparks and bistro for your timely information.
As i work with acrylic and other plastics may i suggest using some type of KY jelley-butter or some machine oil as this will reduce most of the drag on drill bits or saw blades.It prevents the melting produced by the heat.
Laser ?
Is that something you have in your toolbox Nix? :D :D
Generally I find CO2 lasers a bit big to lug around :p
BTW, thanks for the tip about lubricants Rattail, that's worth remembering :)
You could modify a CD-RW or DVD-RW drive to generate huge amount of power and then just hold it up and point. LOL
Well...now that you mention it....I once used a 125 gigawatt electromagnetic pulse gun on a piece of acrylic....they found the acrylic in the other county from what I understand.Quote:

Nice bit of ar$e covering in that last paragraph. You think they'd stick that on the first page rather than the bottom of page 5.Quote:

ie you've just destroyed half the known universe and they come out and say "ah well we did warn you on page 5". LOL
By sheer coincidence I happened to see an advert in a PC mag for this:

It's not quite in the realms of affordability for home use, but I'm frankly amazed that a CO2 laser could be even that low priced. Give it a few years for the price to come down more and maybe we'll all have one :)
I went to Thailand in 1998 and got a laser pointer for the equivalent of A$10 back in Australia I had seen them priced for A$160.
Needless to say now you can pick them up for a 'dime a dozen'.
