You guys are so high tech, I made a metal control panel before - I cut a rectangle out of metal with a jig-saw, made the 1 1/8" holes with a punch, very slowly. And of course I drilled all the carriage bolt holes with a drill :) Working with metal like this takes a very long time compared to working with wood. But I guess now we have lasers and water jets :) Oh my! Who knew? We're living in the future :) And I thought I was so cool for upgrading to pneumatic tools from electric :dizzy: |

I've heard that they are (or at least used to be) used for food products like cookies and what not. They use a food based garnet in the liquid in that case rather than a sand base. I don't know what you could use to cut MDF, but I agree water+MDF=bad, generally. --- End quote --- Most of the waterjets in the food industry are water only. No abrasive. They usually run in the 75K to 120K psi range. A friend of mines dad works in a bakery where they use a waterjet to slice the bread. They push it through the water so fast it doesnt even get wet! The only time you need to add garnet is when you are trying to cut solid materials. We have cut 9" thick aluminum with ours. ;D |

Wow, 9"! You must have used an extremely slow feed rate or else the technology has changed in the last few years. Last I saw, if you had a thick material like that, you would get somewhat random deflections of the jet if the material was too thick. |

Waterjets are pretty slick. I didn't know they used them for food! In response to the OP: I will agree with bkenobi when he said that at prices like that, you're best off trying it for yourself. A pilot hole and a holesaw, with the plexi clamped onto scrap wood. I think there is more in the woodworking forum; some people suggest sandwiching between two pieces, etc. If you're doing more than just cutting button holes, though, such as cutting curves around the corners, I'd suggest doing more research before attempting it. At any rate, $225 is WAY too much for a piece of plexiglass. I'd almost bet you could get a piece of actual GLASS cut for that much (but don't quote me on that). |

Wanted to bump this and let people know about OCIP. You can find my review about them at http://forum.arcadecontrols.com/index.php?topic=99470.0 If you ever need custom cut plexi, check them out. |
