Extra Large Vernier and Sextant Calipers

Extra Large Vernier and Sextant Calipers

These extra large calipers were made by Lionel because the commercial ones were too small for a project that he was working on.

The Vernier caliper is two foot long (61cm) with a 16 inch throat (40cm).


The sextant caliper is 18 inches long (46cm) with a comfortable span of 30 inches (76cm).
