I just purchased via ebay a 0-13mm M&W micrometer and its just beautiful its on my desk and I keep having to pick it up, I have placed it next to a 0-25mm micrometer so you can compare the size difference. Not sure what I am going to use it for other than its very easy to carry around in its fitted case. Never seen its like before in the 30+ years I have been in engineering does anybody else love tools like other people love jewels.   |

That looks quite delightful and very handy: I just wish that I could read one as easily as I read an imperial one!

I know what you mean. Some of the more modern tools look very utilitarian by contrast, however well they work. I have a Polish 0-1" mike which works fine, but it does not have the looks of your M&W.

That's a nice piece of kit. I've still got my M&W 0-1" I acquired as an apprentice many moons ago, I've also got a M&W set that does from 0-4" using spacers with test pieces, I prefer mics to digital calipers [stuck in my ways  ] Err don't think I could read a metric mic  Ron |

This is my beatiful tool - at the risk of upsetting greenies, it's made from ivory with silver hinges -  Notice the complete lack of metric bits ;D |

So many of the old tools were not only beautifully made, but ideal for the purpose.
Even simple items.
As an example, I have a hammer that is well over 80 years old and the balance is perfect.
As for M & W, their tools were always reckoned to be THE best, and that 1/2" mic looks both useful and unusual.

Yes a Holtzapffel ornamentel lathe in good condition has got to be the most beautiful machine tool of all time it has accessories that you pick up and just wonder at.
One on ebay at the moment has a buy it now of 25,000 USD and I have seen them go for more than that.

" does anybody else love tools like other people love jewels." ....so it has been suggested although I would never admit to it. This is a tube rivet / eyelet press and stands about 10" high.  |

I think you will find many people here appreciate well designed and made tools.
That press is both attractive and functional.
Question 1. How come we used to make tools (and many other things) that had beauty and function, whereas today, so many "designs" are as basic as possible with no artistic ingrediant?
Question 2. An interesting mental exercise is to think how you would make that quick thread on the spindle.

a dividing head correctly geared to the feed handle spiggot onone end of the milling machine bed, put the shaft between centres, feed the bed an it ll then produce the thread / helix, its a bugger to correctly work out the gear ratios though, ive had to make a few helix (vibratary) bowl feeders at work before, nightmare.

Hi Ben, would it be easier to make a three or four start acme or square thread on the lathe for this sort of application? I have tried the milling machine route, and it's ok if you have the kit and gears etc, but I prefer the lathe.
Regards

Maybe because then castings were used and now we build up from stock? Look at that press: nice casting. Now we would weld together a few pieces of bar. Works just as well, cheaper probably and just as functional. Not as pretty.

Regards JB in my opinion off the top of my head , yes, a multi start thread would be the way to go as trying to grind a lathe tool to be able to cut a thread that quick would be nigh on impossible to do as i don't think you could get all the correct cutting angles, the side and bottom clearance and enough strength to stop the tip breaking straight off. it may work but it would not be time affective and there would be a fair amount of chatter so yes multi start would be the way i reckon regards Ben |

I've done fast multi starts like that by thread milling in the lathe. I made a acme form cutter in silver steel mounted in a bodged up toolpost spindle, set up the gear train then drove the leadscrew with an electric screwdriver. I finished it off with a wooden acme form disk in the toolpost spindle and some polishing compound.
