hi Marcin ,

Just to fwd you my post ( from OSE workshops facebook page) , it might be interesting for CNC Torch Team future plans:

recent video "Waterjet cutter built with a cheap pressure washer " https://www.youtube.com/watch?v=Lg__B6Ca3jc

, by famous applied science mr http://benkrasnow.blogspot.nl

I see you have started collecting info for water jet : http://opensourceecology.org/wiki/Water_Jet_Cutter

Best, Branko

Notes

As low as $20/hr for 30 hp 0.01 orefice. Cut rate - 7 ipm for 1/2" mild steel with 30 hp, total operating cost $12/hr. 2 largest costs are 1/2 garnet, 1/2 pump/head parts. [2]. Lowest cost is 15 hp at $11/hr.
- With 32 feet of cut per hour - this is decent for 1/2" steel. Can be a main production tool.

[2] 10000 PSI hydraulic cylinder - $300 - [3]
Garnet - 50c/lb [4]. Can be recycled 5x. Usage - about 1 lb/min. [5]
- There are abrasives harder than garnet (shorten mixing tube life) or softer (don't cut as fast)
15 hp pump - [6]
Looks like a 40ksi booster water pump running on air [7]
Intensifier pump - $5k - [8]
Intensifier, no plumbing or valves - $2700 [9]
