I tell my crew that it is used for everything from spreading cream cheese on a bagel to digging dog crap out of a shoe. (I just have to remember which end is used for what purpose). You might guess that my guys don't want me to retire any time soon.

Copper sulfate is probably not a good idea though as a layout fluid, sulfate ions catalyse rust, so are best avoided. The idea is presumably that some of the copper cements out leaving a layer of copper you can mark into. Neat idea, but dyes are probably better and not going to rust up your work. Yes I know steel is often pickled in sulfuric acid. But it does make it more likely to rust badly if isn't all removed.

As a blacksmith (three rivers forge), I'm supposed to "work to the tolerance of a worn shilling", but I can't stand that notion. Give me a steel rule, well oiled, and a scribe. I keep a steel rule in the bib pocket of my leather apron right next to the carbide scribe that leaves a very fine mark. The only time I like soapstone or a silver pencil is when I need to simply grub off some steel. If you tell me you want something 15" long, I do my level best to get it right on 15"...... not 15.1"!!! Nothing more aggravating than a thick line marking something and having no idea where on the line to cut, punch or drill.

I don't know why that myth is perpetuated. A blacksmith works to the tolerances needed for the forged part to fit, and degree of fit is always specified. It's only when the parts get large, rigid and are anchored in use that thermal expansion requires looser fit.

@@andnorIt depends on what processes you attribute to a "blacksmith". The names that we give to trades today are so far removed from their origins that many of them are irrelevant. I'm now an engineer, not a wright, but an information and physical materials manager. "What engineers design, others do wright." ;-D A tolerance of 1mm +/-1/25 inch) for every measurement of a hand forged large part made without any other machining is tough because the parts are worked hot, expanded, and malleable, but measurements are taken when it is cooled. Very few precision parts are forged today without further machining. I received a pretty thorough education in metal working, (starting with my name), through hands-on shop classes in various material crafts - woodworking, foundry, forge and machining. Those clases covered history, development of technology and theory, not just the manual skills. A blacksmith works using heat and impact on iron to shape it. The skill of "black" smithing evolved from general metal smithing which started with easier to process, softer metals like copper, gold and silver. The soot produced by coal fired forges, blown into the shops and onto the workers by the forced air, is where the "black" came from. ) Steel foundry and forge are specializations within the "black" trade. The only tools used by a traditional blacksmith were a forge, anvil, hammer and chisels and the material used was a rough ingot. Originally those tools and ingots were prepared from ores by black smiths. Mill files and metal saws are relatively recent additions, so is the standardized steel rule, all of them built by descendent of the black smiths, building on the work of their predecessors.

@HappyandAtheist It is best to use the system used to manufacture the part or in surveying to use the measurement that was originally used for the original survey if trying to reestablish lines and corners. Most times equivalents can be calculated and used which is just fine. I worked in metric when the job I was on used metric but prefer imperial except when laying out a line then I use feet and thousandths of a foot.

eh, I work in both. Easier to do math in your head on the fly with imperial. rather hard to keep track of dozens of meters down to the millimeter, where simple dealing with feet, then inches, then fractions of an inch is manageable. Speaking about construction mind you. I'd agree that in general the metric system is better when high accuracy and many calculations are involved. In terms of applied geometry though, it's often easier for me when dividing something to use fractions, which in imperial translates directly to numbers and lines on the tape easily. That being said I do all my volumes metric, since it is easier to multiply, and also generally material comes metric, so why do the conversions?

The imperial system is dozenal and not decimal.

Before your rebuttal, with perfect accuracy can you provide me the length of 1/3 of 1 meter?

@@ivankoran I agree fractions are fun, and useful at times, but your use of "approximations" is a bit misleading. You may want to measure 3/16 of something, which sounds much more satisfying and accurate than 0.1875, but if you inaccurately measure 11/64, it's still the same as inaccurately measuring 0.171875. I use both, by the way, and the worst thing is when you have to convert one to the other. Anyway, I'm not telling anyone to use one or the other.

As a cnc machinist, we use both metric and standard, fractions and thousands. one gets very good at converting them! Tho I always use a calculator to insure I do not ruin parts. A few simple tips to make it easy, converting fractions to thousands (lets say 1/8 for simplicity) simply divide 1 by 8 (first number decided by the second) it will give you .125 and this holds true to any fraction! Converting metric to standard, lets say you have 50mm, times the fifty millimeter by .03937 and it will also give you a thousands measurement of 1.9685 Or just under 2 inches This also holds true for any metric measurement Converting standard to metric is simply dividing .03937 by your metric number! there are endless formulas and calculations, but those are a good place to start! There are also allot of fraction equivalent charts available! :)
