    Did not receive the raise i wanted, now what?

    Reading through all these responses, and comments, I find it quite comical. Responses range from "Be happy you have a job" - "grow the hell up" to "lie about it, do whatever you can to get a raise" When I here this it makes me think back to my grandfathers career advice when I was very young...

    solidworks notes with flags...

    Only way to get rid of that is to do it manually. That is pretty darn picky. I have uploaded a block for your reference. StrykerTECH Engineering Staff http://www.stryker-tech.com/http://files.engineering.com/getfile.aspx?folder=e17d343c-a236-488c-86cc-8371d2055cff&file=ExampleNote.SLDBLK

    Bead Rolling Standards

    I think you may be barking up the wrong tree with that one. We used 10ga for some of our large enclosures, we have run into the same problem, with lack of rigidity. We found the best method to stiffen up the box was to shoot a couple weld studs on it and just bolt on a stiffening angle...

    boiler superheater

    How much of a reduction in heat transfer coefficient is needed? 10% 20%? What is the material? Stainless? Inconel? Coating it probably isn't the answer if you need a substantial reduction in heat transfer coefficient. Is there a way you could re-route some of the Superheater so a portion of it...

    Lean Identity Crisis

    My suggestion is to read a book. Or you can get these audio CD's that play in your car everyday on the way to work. I always like them. I felt like I was being lean learning lean. I can tell you this, the basic principle of lean is very simple: "Don't waste time doing something that isn't...

    Sheet Metal Enclosure

    When we design various enclosures we generally follow a few simple rules. 1. Balance the act of minimizing part count and adding complexity to the parts. The less parts you have the less expensive it will be, but the trade off is complexity of parts. Having only 3 parts to an enclosure is...

    U-tube heat exchanger enquiry

    That is entirely possible. Depending on the conditions of the Steam as well as its respective flow rate. "overheat" is a pretty generic description, what temperature is your overheat limit? and what temperature is the steam? After you have this you will need to calculate both your steady state...

    Electric Motor Rated Vs. Start-Up Current?

    Locked rotor current (starting current) for a compressor motor is typically 6 times the full load current (running current). StrykerTECH Engineering Staff http://www.stryker-tech.com/

    Need Help Finding A Resistor Size...

    sDotOne, Make the following hook ups: Connect a 15k ohm resistor from your solar panel positive to your analog input. Connect a 10k ohm resistor from your analog input to common/gnd. Connect your solar panel negative to common/gnd. With this setup, your analog input will be 10V when the solar...

    High current PCB mounted busbar

    We have done that type of stuff. Generally we would get them water jet cut and then have them tin plated to prevent corrosion. StrykerTECH Engineering Staff Milwaukee, WI http://www.stryker-tech.com/

    Overmolded Cable Grommet Strain Relief Callouts or Standards

    Generally when designing a grommeted connection for strain relief, the intent is to transfer the potential failure mode from an undesirable point to a point more accessible or fixable. I would suggest finding that optimal point at which it is as strong as possible with out making assembly too...

    Silicone adherance to Aluminum

    We design sealed outdoor electronic enclosures, we almost never use silicone as the soul solution for sealing in electronics. I would highly recommend using a rubber gasket, or a foam-in-place product. Silicone is messy, hard to apply consistently in production and hard to maintain a consistent...

    Likelihood of SRS overtest/undertest?

    Jvian, Sorry I should clarify, the image I sent was suppose to be the same pulse, but the image on the bottom was the best attempt for a table to replicate the pulse image above. obviously not to scale. It is a problem we often run into when trying to replicate SRS pulses. The sharp transient...

    Likelihood of SRS overtest/undertest?

    Jvian, StrykerTECH performs SRS testing for customers, SRS pulses are tricky little animals. They take for ever to range the system. So what generally happens is the system will range running lower level -12DB or -18DB pulses until it dials in the profile to your specific pulse pattern. The bad...

    OEE - HOURLY CALCULATION

    Interesting. Option 1 seems like it could be well over 100% depending on factors in the equation. When ever I see "goal" as part of a metric I get worried. The "goal" of parts per hour varies? That just doesn't seem right. I would say Option 2 what can you produce, how much is good, and how...

    RFID tags for cart tracking.

    So you are back flushing inventory correctly and timely . . ? But your ERP system is too slow to react to refilling the supermarkets? You have 16,000 unique part numbers? So in a nutshell you are looking to track one cart, then you use the position of the cart to trigger when to fill various...

    Manually Edited BOM Values Disappearing

    I would suggest flat numbering, manually editing the numbers is not generally a good thing. Every time you rebuild the BOM they will disappear, unless you turn off automatic updates then it will just be added to the end of the list. But with indented BOMs if you add a component it can't throw it...

    Simple Pattern Question

    your vary the sketch is greyed out, because your hole is fully defined, take the dia dim off in the sketch, then dimension that when you select vary sketch in the linear pattern. StrykerTECH Engineering Staff Milwaukee, WI http://www.stryker-tech.com/

    Stress in bottom flange of beam

    you're fine, the majority of the stress is in the area where the web contacts the flat portion of the beam, for some reason it isn't let me upload a pic. You have like a 5x safety factor, for static loading. that doesn't take into fatigue or dymanic/impact loading. StrykerTECH Engineering Staff...

    Detailing up a Sheet Metal Drawing

    Before sending it to the subcontractor making the part. Always verify that it does flatten, and is constructed in a manner that takes the bend radi and thickness out of the the tolerance equation. I.E. always bend inside, and thickness inside. That way the manufacturer can change bend radi and...
