    Thank you all for your response. The parts are relatively small (various sizes under 2-1/2" OD and no longer that 6"). They will be machined then welded to a 11 gauge 304L sheet metal. The temperature should not exceed 200°F and exposure per cycle would be less than 2 hrs. It should not be...

    Engineers on time clock

    This happened to me several years ago at a company. It caused much frustration with the engineers. Many of whom put in extra time. Typcial day was 7 to 530-6. When the clock was put in for us we could only clock in 15 minutes before in the morning and 15 minutes late in the evening...

    getting the shaft by boss

    Reading this reminds me of 'don't do business with family'. As anything bad may happen can result in years of bitterness. IMO, enjoy the extra money that you received and let it go. Otherwise, fight it and update your resume'.

    Blame Culture

    Regarding the "Woman awarded $45,000 for cat killed by neighbor's dog". I agree with both SWcomposites and IRstuff. Since I am a "Owner of those animals", not a chow owner; I find the owner to be truly derelict in his responsibilities. It is a matter of one being responsible and having a breed...

    Will America give up the Inch?

    Answer to the question is yes, over a very long time as PSE mentioned. For myself (and I believe many others) went through college using the metric system. Then when we hit the job market we were 'forced' back into the imperial units, because that's what was being used. Many of the more...

    Blame Culture

    Always a hot topic when religion and politics are brought into conversation. Although, I enjoy bashing lawyers as much as anyone else. I will have to admit like any other profession there are good ones and bad ones; every profession has this problem. Earlier post mentioned 'loser pays'...

    Where do you look for jobs?

    Another area you may want to check into is your local (or where you want to live) listing for jobs. Usually, any major city will have a website for that area. Some companies do not list on monster and career as they want a local person for the job. For example, Charlotte NC has...

    Heat tracing pipe with hot oil

    I believe that you are trying to determine the GPM in order to size the pump correctly. Is this correct? I maybe mistaken but I think there is another approach. If you have the heat tranfer oil (specs), you maybe able to work the GPM from another angle. As you want a turbulent flow for...

    Ideas for magazine article

    Thank you all for you ideas. Working with these parts and system layouts, you can get to the point of just taking some knowledge for granted and overlooking questions others may have. So far we have: 1. Effects of filtration into an existing system. 2. Types of Filtration and/or filter media...

    Ideas for magazine article

    I have been asked to write an article for a magazine. Unfortunately, I have only come up with one idea. Our main focus is filtration of hot oils (650°F range, low psi <150). However, we do a lot of custom heating and cooling equipment as well as N2 blankets. Right now, I am leaning towards...
