    What beam do I need?

    Not a question for a web forum. Need to check your local building requirements. Engage an architect and/or structural engineer to design and certify the drawings. A poorly designed beam & support structure will bring all sort of problems if it fails (insurance, code enforcement.....).

    PSI rating of replacement safety valve on compressor

    A bit more complex than "common sense" If you're really interested in the ASME code, I can access that & send it. But the salient points are (from the National Board of Boiler and Pressure Vessel Inspectors): An air receiver must be protected from over-pressure. This is usually accomplished by...

    Torque spec for weathered bolts

    Hate to interrupt the ******* contest that usually arise here. A little engineering information has crept in, but the basis of the engineering is as follows: The torque required for a bolted joint design comes from a long string of calculations, but boils down to a simple equation. T = Wp...

    New Sandblaster, need air compressor

    This is the Ingersoll Rand compressor you need. Should be plenty for a little sandblasting. 5,100 cfm @ 150 psi. All you need is 2,300 volt 3 phase and a million dollars.

    Lessons Learned on GJ

    I learned that many topics are repeated over and over and over again. This topic has been asked several times, not as frequently as 4-1/2" angle grinders, ratchet lube or air compressor size. I also learned, as commented on in the previous "lesson learned" thread, that there is no need to...
