A good 12 inch & 6 inch steel rule
A 6 inch vernia
A good 1 inch mike
I was given a set of moor &wright micrometers up to 6 inch as well as a set of internal mikes
They came from a retired machinist (he calls in now and then for a bit play)
My 1 inch mike was given to me on my 18 th birthday
It has given me nearly 40 years of trouble free service
I recently bought a 18 inch height guage this is a really usefull bit of kit.
I remember at collidge as part of a practical exam , we had to measure a cylinder bore for taper and ovality
Before we even started the teacher told us to measure the bore with a steel rule and write down 3.75 inch
That would get you a pass
He had people get it to within 2 thnths but be 1 inch out
Get the big size first
