Caliper: Spring-Wire Calipers with a Sliding Loop (Boy Mechanic, 1919)
Quick calipers from one length of spring wire, bent double into two legs, with a loop of heavy wire round the middle that slides along to set the opening.
Variable: points turned in to gauge outside diameters, or out to gauge bores.

Fit the sliding loop
Fasten a loop of heavy wire round the middle so it slides back and forth along both legs. Sliding it toward the tips closes the calipers; sliding it back lets them spring open.

Le blueprint yenza
CC0 Isizinda Somphakathi
Le blueprint ikhishwe ngaphansi kwe-CC0. Ukhululekile ukukopisha, ukuguqula, ukusabalalisa, nokusebenzisa ngaphandle kwemvume.
Sekela uMenzi ngokuthenga imikhiqizo nge-Blueprint yabo IKhomishane Yomenzi kumiswe ngabathengisi, noma dala inguqulo entsha yale Blueprint bese uyifaka njengoxhumaniso ku-Blueprint yakho ukuze wabelane ngemali engenayo.
