    Punch presses are like old DNA sequencers (ask me how I know) in that they only run as part of a system of staff and support equipment which costs way more than the machine itself. So once obsolete,...

    I'm in engineering so yes to Solidworks and its ilk. For things like signs though, I think these days, Adobe Illustrator is what most graphics people use. There's an open source equivalent called...

    Are you actually trying to make your own bars? Or form tubing for frame components? Relatively small manufacturers like Knolly bikes have aluminum frames with hydroformed parts, made in Taiwan...

    A final note: we originally were going to get the TRT-100 4" platen 5th axis unit to manufacture a particular component for individualized radiotherapy. But while the machine was on order,...

    This is a good shot showing the clearance involved. I forget the name of this forklift but this is what you get when you are done screwing around. It's like someone solved the exact problem...
  6. New Machine Day - Hole in the Hospital Edition

    This is a major back fill as this actual move happened September 2018, and then we spent some time getting our TRT-160 five axis unit up and running (our timelines mostly) so it got put off. But I...

    Hey didn't you guys see, this CallyTech part is French. That means it's not possible to make it. Or buy it. Well not now.... Come back tomorrow and it might be possible. Well, how many do you need?...

    I'm guessing that this is one off, so the costs won't be bad either way and threading is indeed fine if you weren't planning to mount and demount the parts a lot. If this is a production thing, 10 GA...

    Ox, your response roused me from my torpor! Here are some pretty space-age videos if I do say so myself. No wonder they have 700,000 pieces of tooling, it takes a large number of tools to make one...

    This evolution of the term "cam out" is technically and linguistically fascinating. Thanks for the find plannerpower, and I tip my hat to the thesis author as a bit of history really helps to bring...

    Naive question here: Can you test thinner parts of the same material to get a feel for the press and die set's actual performance? If you could punch say 3/16 but not 1/4" you'd have some idea you...

    As an addendum to this for future general reference, I was watching an NYC CNC video where they have the VM-3 with the older double sided TRT160 (I think it's that size) and indeed they had it turned...

    This s part seems so well suited for standard laser cut and form a specialist shop with a CNC press brake. You're sending it out for laser anyway just have them bend it.

    I back filled our justification for why we got a VM-3 using John Saunders's (NYC CNC) video for why he got one which I saw after we had our machine on the floor. I think we had good reasons but John...
