I have a metric motor with metric mount spacing & thought it would be interesting to grab the Sorensen & see what measurements could be made on the mount bolt hole pattern.
A strait edge yielded 3 15/16 on the left side of the 2 holes & 3 7/8 on the right side.
That's 3 29/32 center to center with quick measuring & averaging. Holes must not be the same diameter.
Sorensen Center Mic time
Yep, that's about 2 1/2' of case for a 13" Center Mic.
Step 1 measured 1.950 (half scale is used in order for the tool to do the math).
Step 2 is positioning the caliper so it's a slide rule type of generating the answer.
Step 3 is the final answer. Close up of results.
3.934" is the answer from the Sorensen. 3 29/32 = 3.9065 from the ruler.
Obviously this is not a situation where precision matters. But it does point out that bringing a ruler to a caliper match has bad results.
