... When I started a Physics class, one of the first things I did for one of my first "Daily Quiz's", using always a half sheet of paper, was put the equation A=LW on the chalk board, I then said solve for W! It was amazing how many could not do that; I had to teach algebra again to Junio...

If you old guys (I can say that, I am one myself) are so comfortable with the inferial system, here's a little problem that you should be able to solve in a few minutes. Given the information below, calculate the correct value of the constant, K, so that the equation works with the units shown. To f...

I believe it's a fitting to convert an ordinary flat anvil micrometer to a spherical anvil. Such a spherical anvil allows the micrometer to make accurate measurements of the wall thickness of pipe-like structures. A flat anvil would form a chord across the inner surface of the pipe and the micromete...

As long as great precision is not required, I might approach it this way. Glue a hexagonal nut centered on one end of the stock. Place it horizontally in the mill vise and, indexing off the nut, cut the hex on the male end of the part. Remove the nut, clamp vertically in the mill vise with a V-block...

... Marv , we are going to the hardware store today in a futile effort to find what I want. All my steam stuff comes from PM Research so I am sure I will end up doing as you suggest. The PMR valves have the advantage of being the right "steam style" and scale (1:12) to fit a miniature eng...

I doubt you will find a commercially made version of what you desire. You'll need to fabricate it. Take a through valve, either self-fabricated, or purchased, e.g. https://www.pmmodelengines.com/shop/pipe-fittings/machined/globe-valves/ and machine a pipe with a circumferential flange that can be sc...

Cut the rest of it into bite-sized pieces, add a handle, and, voila , you have a ruler tool that will fit into locations where the ordinary machinist's rule won't fit. My version... https://www.homemadetools.net/forum/ruler-bits-48981#post69970 used bits of a plastic rule but, clearly, metal would b...

... When the Greeks built the Parthenon, they didn't have the means we have today to test the strength of materials, but the proportions look right. What's left of my memory recalls an article I read many decades ago that someone tested the proportions and dimensions they used with modern technique...

True, metal gages tend to be arbitrary, but to the non-technical person, the use of gage (or gauge) is suitable. To an engineer or anyone working with metals, the actual thickness in inches or millimeters is the only way to go. When it comes to letter and number sized drills, the assigned number/le...
