[edit] Catching the water
How does the water get "caught" after it has cut? If this device can cut through almost anything, what's to stop the water jet? (Perhaps it lands in a pool of water?) —Ben FrantzDale 14:31, 29 March 2006 (UTC)
- A pool of water is correct. There are also vertical sacrificial slats mostly submerged in the pool of water. —Ben FrantzDale 01:55, 30 March 2006 (UTC)
- There are multiple ways to catch the water and hold the material. Some companies use ball bearings, some use metal slats, other use metal slats with additional materials (plastics, foams, etc.) for holding the material in the air. In the case of the pools of water (commonly refered to as a catcher tank), you can actually damage the tank if the jet stays in the same position for a number of hours or longer. They really do cut through anything. Engunneer 23:20, 31 October 2006 (UTC)
[edit] Water jets in food manufacturing?
Are the waterjets in this article the same is the ones used in food manufacturing? (For slicing cakes, bread, sandwiches...) I know some manufacturers use them because they don't have to worry about sanitation/contamination. —The preceding unsigned comment was added by 24.124.29.130 (talk) 07:42, 26 January 2007 (UTC).
- Sort of. Yes, they're the same kind of thing and operate the same way. No, they're not exactly the same models used in "industry," as industry has different models of waterjets for different tasks. Obviously they're not using a waterjet that will cut through a 4'x8' sheet of two inch thick steel to cut the cakes you buy at the supermarket. - Toastydeath 23:52, 26 January 2007 (UTC)
[edit] What's the UMR stonehenge?
and what is it doing in the article? I couldn't figure it out. 132.68.56.153 14:28, 5 June 2007 (UTC)
- good question. I thought I had deleted it before, but I sure did this time. --Chuck Sirloin 14:57, 5 June 2007 (UTC)
[edit] This article needs to be SI standardised.
Inches and PSI are not internationally accepted measurements and generally mean little to people outside north america. LennyValentin 04:07, 24 August 2007 (UTC)
- I added millimetres and megapascals based on an online conversion from the imperial measurements given in the article. If someone has sourced metric figures, please replace mine. It's probably also best to leave the imperial measurements in front, certainly until there are proper metric figures. Leushenko 23:35, 13 November 2007 (UTC)
- The pressure units were wrong. 400MPa gives 4000atm, which is impossible to obtain. The correct is 400kPa, approximately 4atm. fuchsroter 10 December 2007 —Preceding comment was added at 19:40, 10 December 2007 (UTC)
- That is incorrect, and pressures close to atmospheric are what you get out of a Super Soaker. I have reverted it back to MPa.--Ceriel Nosforit (talk) 22:08, 12 December 2007 (UTC)

[edit] wood tool
are jet cutters really used in wood working? It seems like they would do more harm than good by exposing the wood to the abrasive medium an well as saturating the part with water.Boatman666 (talk) 22:32, 22 January 2008 (UTC)
