In the next village to me there are two Garden Centres and one of them has a Antique Business in one of its buildings, I usually visit about once a month as he sometimes has some old clocks that interest me, he usually has a few boxes of tools, most not of interest but my last visit had me return home with three toolmakers clamps and a few other goodies.

Yesterday I wondered along to the centre and nice set of engineers compasses and a scriber stand caught my eye, I went to haggle the price and the owner presented to me a wooden box with lids top and bottom and a carry handle at one end, opening one lid I found three micrometers 0-1, 1-2 and a 2-3, two are made by Brown & Sharpe and the third was made by Ambrose & Shardlow Sheffield, I'd never heard of this company so a search was done when I got home.

Turning the box over and opening the other lid was a Starrett Bore micrometer various extension from 2" to 7.5", after a quick haggle it was mine including the other items.

Congratulations Martin, that is a really nice find, especially if you got it at a reasonable price.

The Starrett is more likely to be a 2"-8" internal micrometer rather than a bore mic.

As regards Shardlow I have a 0"-4" outside mic. They were quality manufacturers in their day

Thor, Yes I got it for what I am happy with, Johnathan, I thought 7.5" was a strange number but that's what my Vernier measured it at fully assembled with the longest rod and spacer. I couldn't remember the correct name

It must have been your lucky day Martin. I like the B&S and Starrett tools. Shardlow were an especially good quality make, I have a couple of their mics, one of which is a mechanical digital model.

Hi Martin, maybe one of these resemble your internal mic.

Ambrose Shardlow was the founder of the Company, in Attercliffe, Sheffield and during WW2 they made Merlin engine crankshafts, and many other mil spec engine cranks. At one time their works was supposed to be the largest engineering works under one roof in the world. I have one of their mics too.

Many years ago a friend gave me a rather unusual Shardlow 0-1/1-2" mic; its operation will be apparent from my photo:


For normal small work the mic could be left with the ancillary anvil in position in the knowledge that greater capacity was available if needed.

A few months ago, I purchased a Shardlow automatic adjustable spanner, a few inches in length. It is a well made and a very solid tool. A quick wash to loosen everything, a brush with a brass bristle brush, and some oil, and it then was completely free and working. The handle is about the same length as my Bahco 6" adjustable. It will open to take nuts from about 5/16" to 1" across the flats. It does appear to be a capable tool, but is just a bit too big to deal with the smaller nuts. It is turned over to tighten or loosen nuts.

Hi Martin

Your photo shows the 1/2" collar in place, so it should extend to the full 8" as you unscrew the thimble. I was lucky enough to get a 124D set for about 10% of the list price when Amazon's prices dropped in 2019 but doubt I will ever measure a 32 inch bore

The micrometers are nice but it is the box that really catches my my eye. I love the catches made from hinges but what are the dovetailed in pieces for?

Its a sliding door which reveals two adjustment spanners.

Lovely Martin, even better that the chap at the garden centre kept it for you. A lovely little bit of history!

Hi there, all,

Why is my first thought to start all my posts with 'many years ago ... '??? Oh, well:

Many years ago, I bought, second-hand, an internal micrometer. Its maker was/is a well-known UK firm (I'd name them if I could remember but the instrument is currently stored away).

On examining my purchase, I discovered that the 0·500" spacer was mssing. I wrote to the makers (it was long before the internet and email!) asking for a quotation for a spare 0·500" spacer to complete my set. Much to my delight, they sent me one, free, gratis and for nothing!! I didn't even have to pay for the postage!!!!

Maybe they deserve recognition for their generosity even after all these years. Maybe I'll dig out the instrument and remind myself and tell you all of its maker!!

Best regards,

Swarf, Mostly!

For a long time, I only associated Ambrose Shardlow of Sheffield with providing crankshafts for our engines.

But they also made precision measuring equipment. Some of which was used in our Standards Room, so must have been good.

For some time, I have had, and use fairly regularly, a Shardlow 15" vernier height gauge.

Accuracy? It checks out as accurate against the gauge piece supplied with it.
