metrology bits and pieces

[brewdexta]

I was supposed to be working on a new lean-to on the side of the barn for a firewood store, but I got distracted and wanted to do a bit of signwriting. I needed a set of small dividers for measuring the font I was going to use on the sign, so went into the workshop and got distracted as all my measuring gear was spread over loads of different drawers in different locations. I found what I wanted but also loads of stuff I forgot I had. So I got distracted again and I'm now sorting all the measurement and marking stuff into one set of drawers, these.

I'm still hunting stuff down but so far I have this

and

There's definitely more out there lurking.

A few bits have interested me, a lot of this was my dads and I haven't been through it in and detail.

First to take my eye was this Starrett bevel Vernier protractor, complete with acute angle bit. I've never used on before but I'm sure I will now I know what it is and what it does.

Then I found these and wanted to know if they went with the other gauges when I sorted it all out,

Seems I do, screwcutting gauges, one for metric and US threads, and one for whitworth.

And this, I thought at first it was a blade.

turns out its a toolmakers straight edge, usually in sets from 2" to 6"

And eventually found a decent small divider. I found quite a few M&W but this one is a Brown & Sharpe. I've given it a bit of a clean. All the stuff needs a good going over, ideal evening job for when the missus is watching her various series on TV.

I also found this M&W internal micrometer

Looking at pictures on line, this

Should come apart and look like this

However the small 1/2" ring doesn't seem to want to come off, I'm guessing it just slide on and its just rusted up. The spanner with the set is probably from a different set as it doesn't fit anything

Anybody have a similar set and can confirm how it comes off?

Oh, my one's missing the vertical piece

The spanner end with the little pin usually fits into a hole in the scale so you can rotate it to set the zero point (it should be stiff). I think you can make out the hole in the first (sideways) pic...

It's an optional extra so not really missing

Was your dad a tool maker like Starmer's dad ?

Whoops way too ambiguous ..... Try again DAPPH .
Was your dad a highly skilled machinist & engineer ?

No. Just couldn't resist an auto jumble He was a time served mechanic but worked in various factories to make money. Started at Ford around 1962 making Ford Anglias, ICI fibres for a while, then British Ropes in the wire temporing team, the finally at Rockware Glass, all in Doncaster. He loved tinkering in his workshop, probably where I
get it from

Thank goodness.

 

[Jezguz]

I've got a tobacco tin full of mic spanners buried in a cupboard somewhere, might have one to fit.

 

[Seadog]

Me too.

Is that now Ardagh glass in Donny? I do a fair bit in there, we supply the DCS and SCADA systems for their furnaces.

Ive got that exact same set, and its free to swap the anvil pieces because I use it for backing up my bore gauge.
I'll take a photo and remind myself how this afternoon and post back if nobody answered.

Yes it is. He also worked at Pilkingtons Glass in Doncaster for a while before they shut.

 

[brewdexta]

I found these instructions on line.

As I thought, the 1/2" spacer is just a sleeve, so should just pull off, the spanner is for adjusting the anvil for calibration. I'll give it a soak and see if it is just gummed up. I haven't applied any force to it yet. I'll look through my other micrometers, it maybe that the spanners got swapped around in the past.

 

[brewdexta]

A bit of ATF and acetone mix moved it, must have been damp at some point.

I think I have enough imperial micrometers....

All M& W apart from this Chesterman that looks mint.

No spanners to fit the internal mic yet, but I keep finding stuff.

 

[jmp49]

Yes, I was just a mite too slow, but I did take the pic showing it loose
Mine is also commiting the heresy of being metric not imperial.
The mic spanners are just tiny black flat c spanners that fit, theyre only about 4-5cm long so easy to not spot.

I wish mine were metric, I can use imperial, I'm of that age where both were used, but I prefer metric.

I do have some of those spanners in other mics, one came with the internal set. The C/pin spanner fits the mic body ok, but the other end is too large to undo the anvils for adjustment. no big deal, I have other spanners for the very rare occasion I'm likely to use this set.
