    Calling All Failure Analysts

    People – look at the people Look for a LEAN, Six Sigma, TQM program or similar gone terribly wrong. Currently I am in a world where companies are implementing programs to eliminate non-productive operations. Unfortunately it is very hard to justify preventive maintenance as a productive...

    Alumina - Optimum contact material for low friction

    IMHO saying "Alumina" is somewhat like saying "steel". Lots of kinds of alumina in the world. Have you been to Coors with your question? Thomas J. Walz Carbide Processors, Inc. www.carbideprocessors.com Good engineering starts with a Grainger Catalog.

    Opinion of new Fiat Spyder

    1. The promotional stuff I saw talked about the Spyder being back so I expected something with classic styling. 2. The car is so over-styled that it looks silly. I know, so is Ferrari but at least Ferrari does it well. 3. $80,000 ? For a Fiat ? Thomas J. Walz Carbide Processors, Inc...

    Opinion of new Fiat Spyder

    Not at all my area of expertise. Went to look at the car and the body shape just looked silly. Sort of an over-done version of really expensive cars. Is this correct or is that body styling really functional other than from a marketing standpoint? Thanks, Tom Thomas J. Walz Carbide...

    Kudos for Kaman

    MikeHalloran, As usual I agree with you completely. The rep really didn’t do anything I consider extraordinary. He found a replacement for a 25-year-old part, ordered it, delivered it when promised, put it in and solved an additional problem for us. This is the way I think it should be...

    Kudos for Kaman

    Mark Bernard of Kaman Industrial Technologies found a new PLC for our old, house - built machine. He also came down and installed it. Then he noticed something else so he fixed that as well. That's it. Just really great service for an infrequent, small customer. Thomas J. Walz Carbide...

    Embedding Nichrome wire in Stoneware/clay - will it crack?

    Might look at how kilns, ovens, etc. are wired. It will grow and shrink. The ceramic will crack. Wind the wire into coils. We used a 1/4" dia. rod chucked into a small electric drill. Wear a leather glove to guide the wire. Wind it tight then let it relax. It will expand to some odd...

    Filtration

    I do not know how happy you are with the tank settling method. Quite often, these things are a real hassle to clean out. In contrast, a centrifuge as the particles in motion is usually fairly easy to put them wherever you want them. A centrifuge can eliminate a lot of clean out time and labor...

    Material selection book?

    You maybe ought to have a Machinery's Handbook, Thomas Glover's Pocket Ref and a copy of the CRC Handbook of chemistry and Physics. You can get the first and third second hand really cheap. ASM books can be o.k. Maybe buy a Material's Handbook. There are several under that name...

    Filtration

    Cyclonic centrifuge. Spins the heavy particles out. great for large volumes of material. Maybe follows that with a mesh filter. Centrifuges typically get out about 90% of the material. Thomas J. Walz Carbide Processors, Inc. www.carbideprocessors.com Good engineering starts with a...

    Material selection book?

    Plating a Brass Part

    Not sure if you want to do it yourself or not. If you want it done then figure out why and ask a couple professionals what they recommend. EN is easy. You can do it on your desk in a mazon jar. Good EN is much trickier. I believe israelkk is referring to what I was taught to call "edge...
