We have to be missing something somewhere. Honestly, I feel conned coming up on some of the technological advancements of the past. This time it is this 1868 boring machine. It is safe to assume that it was not invented in its final state pictured below. There had to be some development, and may be some intermediate models in existence prior to 1868. I just do not see how you come up with something like this from the ground up without any development involved.
Note: In the process of writing this little post, I ran into quite a few interesting things, so make sure you check out those images at the bottom. Check out that 1868 water desalinator, 30 ton portable crane, welding machine, various buildings, ships, trains, luxury railroad cars, engines, subways and other "inventions" at the bottom.
Artwork of the rock-boring machine invented and patented by George Low and manufactured by E. R. and F. Turner of Ipswich, England. The machine is powered by a pneumatic system that can use compressed steam or air. The compressor can be located at some distance, and the machine moved to the workface on rails. The boring cylinder rotates rapidly and also moves up and down, striking the rock at a rate of 300-500 blows per minute. The boring point is around 5 centimeters across. The compressed air that powers the machine also cushions the boring cylinder, and a jet of water is used to wash away the broken rock. Artwork from Mines and Miners (L. Simonin, 1868).

- I can only imagine what else is hiding in these engineering volumes.
!!!: Interesting that just about every etching in this book is accompanied by something like this, "The engraving was done based on the photograph we observed".
When were people inventing and developing? The entire world was fighting: List of wars 1800–1899
Opinions? Is that normal?

Some examples from volume 5.
How about that for 1868?

KD: I don't know what to say. With every next discovery the technological level of the mid-19th century just keeps on climbing. Apart from being naive, a reasonable person would understand that there had to be proper development associated with equipment like this. That, in turn, poses another interesting question - how far back in time does this development go?How about that for 1868?
