    Copying a helix in SW04

    But how did you draw the First tooth? With a helix/spiral? If so How do you terminate the spiral at the end of the extrusion. The trim entities feature is turned off when you select the drawn helix and there isn't a "up to next" available with the spiral draw dialog? Sorry, I haven't really ever...

    Copying a helix in SW04

    How do you copy a helix spiral in SW?? I an trying to draw a helical tooth (Citroen) Gear but I cant figure out how to copy, pattern or mirror the single tooth I have drawn? Also how do you trim and helix/spiral? There's no set pitch, addendum, dedendum, or working depth set for tooth profile...

    Converting a biological vent hood to intrinsically safe

    Thats kind of what I figured, The last place I worked at the hood (I did the exact same process this hood will be used for) Was a solid metal cabinent. Electrical and Pneumatic Connections were standard recepticals in metal boxes connected with metal conduit and fittings, the only difference was...

    Converting a biological vent hood to intrinsically safe

    Our company would like to buy a vent hood, (we found one that is surplus with all the specifications for air flow, lighting, etc.. however, it is not intrinsically safe) Is this just a change of the motor or just the wiring or both. We will be using solvents for vulcanizing in it and I would...

    DC relays capable of 150Vdc & 3Amps?

    You definately want to stay with Solid State for the intrinsicaly safe route, if that is a concern. The idea that skogsgurra suggested is the right way, just add a capacitor in the incomming line to the charger to absorb the shock from the draw. You could use an opamp and some resistors to turn...

    Relay race solutions?

    Try putting a thermistor on the A/C line incoming to the equipment. Sounds like the initial power surge coming in is doing you in. You could save some money if the power to the relay power (AC/DC) is less in voltage and watts by putting the thermistor there instead of trying to find a high power...
