This would be just the thing for when I need that 'third hand'. I think I'll put on my wish list.

Nice one that is just what I need
What brand is your micrometer?
I started out with nothing and I still have most of it left.

Looking for a Hensly &Gibbs #258 any thing from a two cavity to a 10cavityI found a new one from a member here
I got one for my tubing mic. It won't close on the skinny frame of that particular one, but works great on all the others. Can't go without one now.

Well now I need one!

HHmm??, been a machinist for over 20 years now and I've never seen one of those before?, never had an issue holding the mic in one hand and the part in the other??

Darn My Starrett I bought in 60 never has complained YET about the way I handle it.
Now it may not like getting squeezed by that clamp.
WE WON. WE BEAT THE MACHINE. WE HAVE CCW NOW.
I wish they made those to measure 105 and 120mm haha. Those large measurements almost require a third hand. I might pick that up soon. Thanks for sharing!!

Cute!
40 years in the trade and I've never seen one.
I've been using a small ball-swiveling vise that has rubber faced jaws for years. No idea what I paid for it, but it wasn't much. Advantage is I can adjust it to whatever angle is convenient. Mine looks something like this one: http://www.amazon.com/Bessey-BVVB-Va...&keywords=vise
I normally hold the mike with little finger in the frame and thumb and fore finger to turn thimble holding part with the other hand. I even use thread wires with out the stand. The stand really dosnt give you a third hand as one hand is still needed to hold the part and one to turn thimble. To gain a third hand the part to be measured should be in the stand or holder. Production inspectors use these alot though.
I've had one for 30 years and it comes in handy when you've got to measure a bunch of parts. It sits on my bench and is used when necessary. These are more common in inspection rooms than on the floor, although it is a totally appropriate device for measuring large quantities of parts in a run on a lathe where you have to monitor one specific dimension, and especially if you have to chase that dimension.
The cool thing about these is it is easier to get a consistent feel when measuring many parts since you can more easily use the little knob on the mic to repeat turning pressure on the thimble.
It works really well for measuring boolits.

Like Randy has mentioned, never needed one on the shop floor unless absolutely necessary, but in the inspection department they do come in handy.

Surprised at all you machinists not having seen one before. They have been standard equipment in every inspection dept. I've ever had to do with, and that's quite a few, since a large part of my career was in metrology. Main objective is to keep body heat away from the mike, but convenience is also a factor.
BTW that mike is a spittin' image of my Fowler, which up into the '90s was made in Switzerland, and a fine piece it is. They show up on evilBay from time to time, often for $40 or less, cause nobody knows what they are. I'll take mine over a new Chinese Starrett any day.

I watched a 1" mic change .0007" over 70°F. For most things warming the mic a few ° may not matter, for a stack of turbine blades or some such in a temp controlled room it could...
Surprised at the machinists that haven't heard of them, a guy that was a helper at a machine shop told me about them in casual conversation, I just assumed they were pretty common.

I've actually tried the heat of the hand test, and with a 1" mike I could get about 4 tenths in just a couple of minutes. Try it against proper gage blocks, not just "zeroing" it. The problem is that your hand heats the frame but not the spindle. This was my field, if I can ever be said to have had one. Twice I wrote mil-spec quality assurance and gage calibration manuals for my employers. Last 15 working years I was with Zeiss, a company whose "ordinary" measuring machines resolve down to 20 millionths or so, mostly upgrading GM/Ford powertrain plant process controls. When you can measure that precisely, you learn a lot of things that you didn't know you didn't want to know about how temperature influences measurement. Bottom line is: nothing is stable when you can measure millionths as easily as a carpenter does feet and inches. The machine tool builders hated us, but we showed the way to huge improvements in the quality of their blocks, heads and cranks, as well as transmission cases, rear end cases, etc. Lots of war stories to tell, but I'll save 'em.
