    Great build, Ben. Have you thought about actually building a hydraulic intensifier? I think that there is a niche opportunity less than 50kpsi and greater than typical limits of commercial/household pressure washers.

    I don't know the answer to this question, but what are the pressure limits for hydraulic compression using a multi disc 'tesla type' pump? might this be something to consider? Doug

    Nice job Ben! Just started a build myself and intend to go the CNC route. Was there anything special about the plunger you turned with the larger inside diameter? How much larger did you make it? I all ready have the x-y table ready for the cutting nozzle setup but I'm still aways away. Any thoughts or help would be appreciated, thanks!

    Hello Ben! Fine work, you're a great inventor! One request. Can you specify the size of the cutting head (mixing tube) and the diameter of the orifice's channel in millimeters?

    These machines are great work horses and will last a lifetime if treated right. I've found numerous quilting boards that all agree on these machines being reliable.

    I can’t believe focusing long enough to research; much less write this kind of article. You’ve outdone yourself with this material without a doubt. It is one of the greatest contents. best self-cleaning water dispenser

    Hallo Ben,
    It's impressive machine.
    Have you tried to cut stainless steel or glass?
    In the movie, you cut from the edge. Does the device drill through the material?
    Best regards,
