    Shrink Fits for compound tubes

    When three rings are used it is usually because two wouldn't perform, so it is extreme. There is an associated risk to the health of the assemblers and operators of those rings. Inexperienced design just adds more risk. Going with Strecon utilizes the best mechanical property of metal...

    Partial nitiriding in part (within part variation)

    >Q 2. Is there any other method? We tried portable vickers You can perform hardness tests to the questionable areas, do a hardness map to find variations. Or you can make a similar sacrificial part, maybe one with no teeth, that you can cut and check hardness at will. Remove a surface...

    Terms relative to Press work

    . Shell Press, in the old days it was a large custom press used to make artillery shells. But I think you are asking about Clam Shell Presses. They are small table-top units, used for bagging and packaging products. Die Set = Die Shoe (usually an upper and a lower make a set)...

    Any ideas for reducing flammability of an oil spray?

    Leonardo DaVinci's self propelled cart --- follow up

    It wasn't covered, but I believe these self-propelled carts have a way to program the steering inputs. It would be interesting to know if Da Vinci mentally visualized these designs before putting them on paper or if it was a lengthy evolution. =================================== Forging...

    Leonardo DaVinci's self propelled cart --- follow up

    As most have seen the sketches and drawings, it is interesting to see some sort of proving. A while back I read about somebody testing the pyramid shaped parachute from a high altitude; reportedly it worked. That takes a brave soul. =================================== Forging...

    How to get study grants?

    Lesko is in it to sell books, so he makes marketing claims. His book, I read 12 years ago, has what the op asked for, which is names and numbers of people and the names of some programs that the gov creates. So the "free money" stuff is a moot point. ===================================...

    Hammer versus press forming, kinetic energy vs pressure

    Theoretically the two presses can cause the same force, which can be compared, you just can't use the same equation to derive them. The forces can be measured and compared, but the quality and accuracy of the measuring will add variables. Depending on certain factors, the outcome can be...

    Hammer versus press forming, kinetic energy vs pressure

    For some really slow hydraulic presses you can see the ram stop once it touches the workpiece, then it builds up pressure, overcomes the workpiece then continues traveling. Sometimes it is hard to detect the stop in motion or the speed is negligible. These small and simple hydraulic presses...

    Hole Inspection System

    That will take several different tools. Look at a few gauge catalogs and see what fits your needs. Or if you contact a gauge-builder, they will surely quote you something. If you don't have a builder, look for one in Michigan as they could use the work right now...

    Selections from the retromuseum

    The report I saw, said that guy was hurt, cracked ribs or something like that. He has added a horizontal wing at the back to try and keep it from throwing his body up & forward. That is fun to watch and think it would be viable form of transportation. I have seen photos of similar working...
