    I've only ever had luck with refrigerated air dryers. The various other cheaper products don't work well or long. Desiccant filters are a PITA with constantly changing/drying media. In a blasting...

    Correct. This way looks a little funny just so stop overrides start, in the event of a short or something.

    Just don't overdo it. The sound of crashing sheer blades is one I won't forget.

    My RPC was a dual motor 10hp/40hp idler. The 40hp motor was a dead short, and attempting to connect it after it was up to speed dropped the 240V line to around 160V or less, causing the potential...

    I would personally space the VFD off of the back a little bit and put a vent near the back on the top and bottom of the box to improve airflow. Shroud the top vent to minimize stuff falling into it....

    Either you pay for CNC controls or you pay for tooling. If you have to bottom bend everything it gets pricey. Even our old 80's hydraulic brake with a factory CNC retrofit holds within a degree with...

    I did provide a schematic, with the intention of swappable resistors. I don't use resistive soft starters so I don't have an recommendations. Plus, you will never get an overload condition powering...

    I don't usually source fuses that large, but I did find a Hinode datasheet with the same numbers and a trip curve. The curve doesn't look like anything special to me, so as long as you can find a...

    Isn't there a contactor that closes after a delay to bypass resistors within the soft start? I generally size contactors to be protected by the supply breaker. Maybe this isn't necessary. (Actually I...

    You can hard wire the resistors and use a disconnect as well. The part I don't like is being able to attempt to power loads if you forgot to bypass the resistors and end up burning them up. Maybe...

    The soft starter at least needs to be rated to the pass through amps so the contactor that bypasses the resistors can handle. Good information about soft starters, though. That 58% value means the...

    Well, the breakers are tripping on the inrush so the supply impedance isn't an issue. If the impedance was too high, the inrush would be limited naturally.

    I have used many transformers that only...

    I believe the amount of flux that the core "maintains" is called hysteresis. It also results in core losses, but typically only at high frequencies.

    Well it's connected to all of the other live stuff. No matter what you do here it needs to be in an enclosure. There isn't enough energy dissipated to warrant venting. You can get just as hurt with...

    To be fair, if a resistor gets hot it's just doing it's job.

    Well, you are feeding it through a 100 amp breaker, so I would use a soft starter rated to ~36kva, or about 50HP.

    As far as part numbers go, I'm not sure. I'd build something like this instead of...

    That particular brake is a very small machine with limited tonnage and not much span to flex. I would consider that more of a bench top machine IMO. Any machine meant to sit on a bench or a stand...

    Honestly I'll probably be making most of our round parts standing up in a mill anyway. That makes the keyway broaching much easier.
