Making the measuring and marking-out sticks
In order to position the cutting block which makes the V-shaped cuts in the marking-out sticks to an accuracy of 1/10mm = 0.1mm it was necessary to make a vernier scale using a small piece of paper with 0.9cm divided equally into 10 parts. Then, just like using a vernier caliper or a micrometer, it was possible to position the vernier scale, fixed to the cutting block along the main scale, with a precision of 0.1mm. This photograph shows the cutting block, with the cut already made out of the marking-out stick, positioned at exactly 40.00cm = 400.0mm along the main scale.
