Angry Mitutoyo maintenance

Some of my Mitutoyo tools have been sitting for some time and I decided to check up on them.
I'm convinced the softer foam that is in the Mitutoyo cases will pit the chrome on the tools.
The majority of pitting is anywhere the tool made contact with the softer foam.

At this point I would say anything is better then the foam they used, I just placed a paper towel in the case and may look for some velvet later.

My tools are over 20 years old. keep an eye on the foam, if the foam starts too feel funny get rid of it. that's when it starts the damage.
I would hope their new foam is better or whatever they use now.

Picture 1,2,3.
My depth mike, The non-chrome steel rods cleaned up ok, just slight rust on one of the ends of one rod.
again some pitting of chrome on the base.


Picture 4.
My bore mike, there was a foam cushion placed on top of the tools and the majority of pitting is on top.

Picture 5.
Pitting.

I put a piece of VCI paper in the cases of the tools I dont use everyday. It keeps them oh-so-fresh

I don't have a clue as to how the newer foams will hold up over the long haul
but I still like the idea of a "SOFT" wood form to locate and support a delicate
device. I made such a filler for the 1" mike I bought in 1956, used from a friend
and it has worked fine ever since. I took a chumk of balsa wood and carved
the cavity by hand with an Exacto knife. Now-a-days, a mill and a cnc pgm.
would do a great job. :-) That was my first micrometer and I'm still using it.
A Millers Falls, paid all the way $10 for it. Came in a wooden box with box
joints and a sliding lid.

I recently gave the only decent 0-1" mic I had to my cousin. The Starret mic had belonged to our Grandfather and since I had alot of my Grandfather's tools, I gave the mic to my cousin.

This left me without a good 0-1" so I broke down and bought a new mitutoyo digital, while I was at it I got a 6" digimatic caliper too. Anyway the new Mitu tools came in a blow moulded plastic case with no lining. It was probably a cost issue and not a "damage to tool" issue, but Mitu did away with lining their cases.

I have seen similar damage to the finish on firearms, mostly handguns. In most cases it was a result of WD-40 use. I don't like WD-40 or foam case inserts and recommend both be avoided for long term storage. Just my 2 cents.
