World’s Oldest Micrometer – 1776! Who made this thing??

After months of communicating with Ben Russell, the mechanical engineering curator at the Science Museum, London, I finally visited and we took a very close look at the micrometer reputedly made by James Watt.

    I can see what could be where washers sat for the base mount, a faint outline(10:18). Or maybe wishful thinking.

    Most likely made by Watt – we must remember that a micrometer did not exist and Watt was thinking on how to make an instrument to measure distance for a specific reason – there were no rules only some general ideas on how to build instruments -refinement came a lot later. There is a similar problem in mathematical proofs – the original proofs had errors that were corrected – just as it been said (I think by Gauss) we see the Cathedral as-built not the scaffolding used to build it.

    BTW thanks for the references.
