    I've never had issues sourcing garnet from Barton. I went to college with a guy in the family that owns Barton (oddly enough) - still waiting for my buddy discount though....

    Since we're all here, has anyone tried the MG-1? I got a free sample with two tons of HPA, but haven't found the down time to switch it out and try it yet.

    I prefer the MG-1 cut quality over the HPA-80 but supply problems exist currently so we can't get it. The Barton rep. I talked to at Fabtech was surprised I preferred the MG-1 but mentioned the there might be some finer particles of garnet mixed in producing a better finish.

    I swear the MG-1 has better finish and less taper and I can push the feed override percentage. I'll probably switch back when it become available again.

    Interesting. I never tried ordering after I got the free sample.

    Any chance you could share what metering disk you're using in the hopper, and what flow rate you have in the software?

    I was actually talking to the CEO of Barton at a wedding a few weeks back, I wonder if I can call in some favors to divert a ton or two my way...

    We have been using MG1 for a little while. I think the particle size averaged around 100, so it should produce a little cleaner cut than 80 grit. MG1 is no longer available due to India’s export ban. We just bought the last stock they had, at least in Louisiana. I think they said it looked like there was still some in CA when I ordered it. Now they are offering 80STL as a replacement which is not actually garnet but seemed to cut fine. The particle size is definitely larger than the MG1 though.

    I wouldn’t let one problem sway you away from a supplier. All suppliers will have problems now and then. Definitely check out OMAX, but I wouldn’t throw the Flow quote away just yet.

    Sorry for the delayed response, didn't get a thread notification. I have a variable opening mini-hopper on my WardJet set to about the 3 setting which gives me 0.7 lbs per minute with a 0.010"/0.030" orifice/nozzle combo at around 55KSI

    That’s very helpful thanks!

    i second looking at both. omax has its own issues. ive heard people using "hybrids" between the two too. something about the best of both worlds.

    IMHO, flow does make a decent waterjet table, but their pumps are trash, at least the one I operated for awhile. Get a KMT dual intensifier if you want awesome seal life and quiet operation. Flow's software and hardware are fantastic, but the dual intensifiers they have are noisy and always seem to leak. I personally had a constant problem of pitting on the high pressure seal face in the cylinder end blocks. I'm not sure if they are still around but Techni waterjet had the best customer service you could imagine. The engineers always had the solution to my problems, and would walk me through every step until a solution was found, although their software lacked compared to Flow.

    which model series are you using from Flow? Are you using taper removal or 5 axis capabilities?

    Does anything need to be reconfigured when you switch out a pump on a waterjet like that? Is it just a few sensors and inputs/outputs you need to plug back in, or do you need to do something on the software side also?

    how's the Omax working out? The machines seem pretty nice, the only thing I can't get over is why they have that giant old computer on all their top of the line machines, and slimmer computers on the new ones. Is it due to their controllers?

    I love the Omax. Been using it almost every day on little projects around the home shop.

    The "giant old computer" is actually a housing which hold a "slim line" computer and Monitor. There are also some electronics in there too. They do this to protect the Computer from getting hit with slurry if you get a splash.

    We've got an Omax in the shop and I'm also perplexed at why they use that hulking computer/control cabinet. It makes their machine look outdated and was almost certainly designed to house a CRT and larger computer, which they have since replaced with smaller versions. There's a ton of empty space in the rear of the control box.

    The software interface is also so clumsy. I feel like there's room for an upstart water jet mfg to make a decent machine with more intuitive software and absolutely obliterate the dinosaur companies like Omax and Flow.
