Where to get cut PlexiGlass
Alfons, Fri Mar 24 2006, 09:24PMHi,
I'd like to build my own electrophoresis chamber out of plexiglass and I found a very good DIY guide, but to be able to construct it, I need plexiglass.
Of course PlexiGlass is available here in Belgium, but I didn't find any company who wanted to pre-cut it for me, and I don't have the right equipment to do it myself.
I need the following:
◦ 2 pieces: 3-3/4†by ½†by ½†thick - for Gel Carrier Sides
◦ 1 piece: 3-3/4†by 3-3/4†by ¾†thick - for Gel Carrier Base
◦ 2 pieces: 7-1/2†by 2-1/2†by ¼†thick - for Chamber Long Sides
◦ 2 pieces: 3-7/8†by 2-1/2†by ¼†thick - for Chamber Short Sides
◦ 2 pieces: 7-1/2†by 5†by ¼†thick - for Chamber Lid and Chamber Bottom
◦ 1 piece: 7-1/2†by 1-1/4†by ¼†thick - for Chamber Lid Front
◦ 6 pieces: ½†long pieces of 3/8†dowel or square rod - for pegs
If anyone knows where to get it, or if anyone is able to cut these pieces for me, please tell me! If anyone of you is interested to cut the pieces for me (I will pay for it, of course), please PM me.
Thanks.

Try your local machine shop. They will order the stock materials and machine it to the size you need it. It won't be cheap though.

To cut plexiglass I've found the best method is to use a cheap soldering gun as a hot-knife. Just use a metal straightedge and go slowly, scoring the plexiglass as deeply as possible. Then place the spot you scored exactly on the edge of a table and snap the plexi. After this you can sand the edges and run a torch flame over them to get a shiny transparent edge. Takes a few tries to get the hang of it, but I've never had any problems.

I just run it through my table saw with a plywood blade which has a ton of very small teeth. Run masking tape on both sides of the cut and it'll be a perfect edge. You could do it with a standard circular saw too.

the score and snap method is good, but if you have a wide piece, and don't have a good clamping solution when you snap it, you'll very likely get breaks that creep away from your score lines. Not to mention the fact that the edges of a snapped piece arent very clean.
Plain old table saws work pretty nice. Keep your hands away, and dust is hot and pointy, but it cuts readily and cleanly. Band and scroll saws work well too, with obvious limitations. Dremels and soldering irons are both not very good, the plastic deforms and bubbles form the heat = ick.

Depending on the size, I've always used scroll saw or bandsaw. Those typically go at a good slow speed, if yours are meant more for wood.
For larger pieces with straight edges (like if you're doing a tank), I'd go with the tablesaw method with a fine blade. May be a bit overkill though, but would be the easiest way to keep the edges perfect.

I have found that a diamond saw blade cuts plastics very well with an extremely fine rough end. It was so fine that after a few scrapes with a carbide kinfe it was ready for flame polishing and came out much better then the saw blade cuts earlier. No sanding was required.
I am wondering if a highly polished smooth razor-like blade without teeth would do a better job. this would be very interesting! Topic: Laminar flow to cut thermoplastics without distortion.
anyways, if you have a clean diamond blade they work well.

To cut plexiglass (or clear acrylic sheet) I print the design onto paper, stick the design to the plexi with pritstick (water based glue stick) and cut with a dremmel using a wood saw blade, or for more intricate shapes a file typ bit works well. The blade/bit gets hot real quick so it melts the plexi more than cuts.

I use a bandsaw with a woodcutting blade to cut mine. As long as you work slowly and steadily it works wonderfully. Just be sure to make relief cuts if you're doing long arcs or circles

yep...bandsaw works great and there are plastic blades from the hardware store for circular saws, just got mine for $12.
