The Newall Engineering Co, Micrometer set, please help identify

Geob10 · Sep 26, 2016

Hello

I am trying to find out about this old wooden box, micrometers and accessories. I bought them at a sale, I did not know what they were but loved the box they were in. So far I have found out that the smaller micrometer in the photos is not that rare but still a nice piece made by Brown and Sharpe but I cannot find out anything or any other micrometres by the Newall engineering co, sorry for my lack of detail as I know nothing about these tools.

any help would be greatly appreciated! many thanks

Various things in there suggest it may be a multi-anvil type, with different length rods to be set in it to produce different ranges, up to the maximum opening.

May simply have been adjusted by moving the long rod that is present in the frame, with the "standards" (standard length rods) used to set position and calibrate the thing to read correctly at size ranges of 1", 2", etc (or mm sizes) up to the maximum, which might be 4" or so (100mm if metric).

Appears to be set for smallest range now, and would have 3 more sizes, according to the number of places for rods held in the case. The shiny rods of which I see two, are likely the original standards. The ones with black plastic handles are later additions tossed in the box, as is the other mic, which would not be needed since the large Newall would cover that range.

Looking again at the thimble in pic 3, it looks metric, with 50 divisions and what appears to be a vernier visible..

hi, thank you very much for all that information, I have never come across these before so it is all very interesting to know. Yes on picture 3 the numbers appear to be metric (spaced in cm's) I guess this means it I not very old? also do you now why I cannot find any other micrometers from Newall Engineering, their are lots of other ones including the brown and sharpe one in the box on ebay etc

Something here Newall Engineering Co

I will keep digging, as a lad I used a newall jig borer.

I'm pretty sure this is the same Newall NEWALL ENGINEERING – 19 to 1988 | Newall Group History & Memories

Geob10 · Sep 26, 2016

great! thanks for your help, yes its definitely the same one, it mentions the premises where the box was made (picture 2) I'll see if I can get in touch with them

I replied to this earlier and it seems to have disappeared,

Newall made Jig borers ,cylindrical and thread grinders, lapping machines ,thread gauges as well as specialist gauges and tools, measuring machines and no doubt other precision equipment, but I can't remember seeing micrometers before.

I would guess that they were not into the mass production of micrometers like Starrett and Moore and Wright hence why they are rare. Whether this makes your mic worth a lot of money I don't know.

Geob10 · Sep 26, 2016

ah no I cannot see your previous post. I have just emailed the website posted above to see what they know about it, there website is under construction so whether i'll here back from them I don't know. I've just seen it was your comment in the metrology thread, I posted it there as well

Looking at that pattern of mic and the string whipping on the hand hold, I've a feeling that was made for use on a cylindrical grinder, possibly a crank grinder both of which Newalls built.

I've never seen a " Newall " micro before in my travels.

Regards Tyrone.

I like this idea, it does have the Vernier scale of a "grinding Mic"
Perhaps supplied as an accessory with the machines ,hence not very many around.

I like the cutout in the side of the box, so you can put the mic away while extended.

The interchangeable anvil mics I've seen have an adjustable stop collar on the rods, and usually come in 1" increments. This one seems to just go in a hole and can be set anywhere, using the standards, and then locked down. Kind of neat if one wanted to use it as a comparator to specific dimension.

JST · Sep 27, 2016

I think you can see the vernier on the mic, along the edge of the thimble and mostly covered by it.

Geob10 · Sep 27, 2016

here is a picture of it on its own, might be clearer

A old multi-anvil mike, with two of the three anvils missing. I wouldn't want it if given to me.

What material is the main bow frame made from?

I think there is just one anvil that slides ,so it is all there.

I have used a big mic (something like 4 foot) that is the same pattern ,aluminium frame and sliding anvil, I don't remember what make it was.

Geob10 · Sep 27, 2016

the main bow seems to be aluminium and the rods steel.

Leg17 · Sep 27, 2016

Consider a the arrangement of a crankshaft mike and then take a second look at this one as if it was intended for general OD crank grinding with more range than typical automotive.
I think Limy and Sable are on to it.

Limy Sami · Sep 27, 2016

Thanks Leg17

FYI Crankshaft mic (note the long anvil- to clear the webs) T436RLS-3 1/2 Automotive Crankshaft Micrometer

FWIW I thought it might be Alu, .....at one time a not uncommon material on engine measuring gear here in the UK, ......probably post WWII austerity kit.
