JohnD Posted January 12, 2018 Share Posted January 12, 2018 The tools of the the engineer fascinate me. Micrometers, so simple, so accurate, and in a whole range of sizes. So here's the opportunity: https://www.bidspotter.co.uk/en-gb/auction-catalogues/asset-disposal-services/catalogue-id-asset-4-10006/lot-62339c33-b97d-458a-8c59-a84000c1857b https://www.bidspotter.co.uk/en-gb/auction-catalogues/asset-disposal-services/catalogue-id-asset-4-10006/lot-66285ac9-7089-4993-b35d-a84000cd3b2e In two lots, a full set of micrometers, from one to TWELVE INCHES in fractions of a thousanth! Oh Joy! That apart from those up to 3", I cannot think of why or how I should need them, to have that full set would be like owning a complete set of cigarette cards, or a Royal Flush at poker! Anyone else have asimilar obsession? Link to comment Share on other sites More sharing options...

Nick Jones Posted January 12, 2018 Share Posted January 12, 2018 I've got a a fair few that came with my mill and lathe including a set of micrometers from 1 - 6". I'm not a precision engineer by nature so I mostly use my cheap electronic "very near" which is what real engineers call verniers. Nick Link to comment Share on other sites More sharing options...
dggt6 Posted January 19, 2018 Share Posted January 19, 2018 Being a bit of a tool nerd myself, my I pass on a bit of nerdiness about vernier calipers. We shouldn't generically call them "verniers" especially the digital variety. The word vernier refers to the vernier scale marked on the caliper not the actual tool itself. Vernier calipers are calipers with a vernier scale. "Plain" calipers were often used just to transfer/copy a size from 1 item to another without actually giving a "measurement" reading. Before digital readouts the most accurate way of visually measuring was to read the vernier scale. You would read the main scale to ascertain the "major measurement" such as each millimeter and the vernier scale would give you the fraction of the millimeter, eg .6mm. The most accurately aligned indicator on the vernier scale was the fraction. In the image below, the caliper is measuring .36 The zero on the vernier scale is past the .3 indicator line so it is .3 and a bit. The number 6 on the verier scale is the most accurately aligned mark to the main scale therefore the extra bit is .6 So the true measurement is .3 plus .06 = .36 Being a woodworker, I have never really worried about about vernier calipers or digital calipers, for as my trade teachers would say, "nothing that half a pound of putty wont fix!". I often apply this advice to my auto body repairs!!!!!! Link to comment Share on other sites More sharing options...
egret Posted January 19, 2018 Share Posted January 19, 2018 At the opposite end of the scale, this is dangerously close to being a toy rather than a tool. So at the risk of some rather sharp intakes of breath, I got one of these for Christmas: https://www.cultpens.com/i/q/CL54321/cleo-messograf-mechanical-pencil-07 A slightly heavy, odd shaped, but actually quite nice pencil with a vernier on the side. Also has capability to act as tyre tread gauge and info on machine thread sizes on the side. No idea on what the accuracy is, but for measuring the occasional item under about 90mm it's not bad. I dare say that for the price you could buy both a number pencils and a more accurate vernier! Link to comment Share on other sites More sharing options...
JohnD Posted January 19, 2018 Author Share Posted January 19, 2018 Cool, egret! I'd put that with my retractable biro that has a soft rubber tip around where the biro comes out, so I can use it on the tablet, instead of my fat fingers! And I'm most envious of Roger's lovely cased, micrometric measure-all! I have a bore guage set, like this: https://www.ebay.co.uk/itm/6pc-Telescopic-Gauge-Set-8-150mm-cylinder-bore-telescoping-id-internal-inside/263071189826?epid=554332930&hash=item3d4043cb42:g:xKUAAOSwN8FZqoEH I tried to use it recently to help a friend who was undecided about reboring an engine that had a palpable ridge at the top of the bore. It prove much more difficult than I thought to demonstrate how much wear was present. My procedure was to set the gauge in the bore, wiggle it to place it in the widest part and lock it. Then tip, to remove it and measure. I had to use a vernier caliper as didn't have a suitbaly sized micrometer (OH! for that rack of micrometers!) But it proved difficult to get consistent numbers. If I were to do it again, is there a better method? JOhn Link to comment Share on other sites More sharing options...

JohnD Posted February 3, 2018 Author Share Posted February 3, 2018 I wasn't entirely truthful in my OP, as I do have a few micrometers, and just today, thanks to eBay, I have made up the set, from 1 to six inches in one inch steps. Oh, joy! The nerdy pleasure of the complete set is not diminished by the certainty that I shall never use any of them bigger than the three inch in anger, and in complete honesty even those rarely. But to know that it is possible for me to measure something to one thousanth of an inch, be it anything from up to six inches wide, is immense!

Hello John Do you want to borrow a set of gauges to test the accuracy ? That,s assuming you have the feel(the rat sh*T helps but it is feel!) Perhaps we are thinking we are precision engineers ? or just getting a good fit(there is a difference!) Roger ps is there one missing?

John what have you got that needs a micrometer that big? I have used then in my early days at a paper works that had rubber rollers that were ground to size I think the biggest was 36" dia And they embossed the foil for cigarette packets and printed bread wrappers in waxed paper!

JohnD Posted June 28, 2018 Author Share Posted June 28, 2018 (edited) I don't have any need for even a six inch micrometer, but I've got one. Whats the biggest there? Is that biggest one 36"? If no one else wants them, for £20 that's got to be a bargain! Does anyone have the phone no. for Micrometers Anonymous?
