Does the left end of that top scale slide out like a caliper?That Red End is the type of wood folding rule that I'm used to seeing.
I thought I'd show a few more specialized ones for machining. First off a machine level. The precision is far higher than a normal carpenters level. This one is 0,02mm per meter. (In practice one often has to use a normal level first just to get within shooting range of the measureable range). Then there is a tool setting sensor. It is used to measure the length of machine tools. Important for instance when lowering as the recorded length lets the machine know when it can expect the tool to touch the workpiece. (Mistakes here tends to either make for lots of cutting air or very loud and expensive bangs). Precision down to about 0,002 mm or so. And the last one here is a 3D touch probe. It gives a very precise measurement of tip movements either upwards or from any side. Used to locate workpieces and features, as well as placing jigs, machine vises or other clamping or reference equipment. Precison about 0.01mm in any direction.

(Some tasks need more than one). These are combined with various kind of holders to bring them into position, and will then register changes in one direction. Precison somewhere around 0,001mm. They can hold onto minimum or maximum values, and be connected to a computer for those so inclined. (I've never tried or had any use for that). Being digital they give very precise readings, but sometimes change in itself is more interesting than actually how much the change is. For those situations I prefer the analog style dial indicators. These digital ones do simulate an analog scale too, but something about a dial needle moving is just very straight forward. Next is an old depth micrometer set. Basically for measuring depth of holes or grooves or similar to a precision of about 0,01mm. Then there is an internal micrometer set. It expands so one can measure internal distances of stuff. Precision as above. Last I included two niche ones. Those are screw in hole transfer sets. They are utterly useless 99,99% percent of the time, but when you do need them you really do need them. Say you have some metal part that need to be replaced. Some bush fix back when it was mounted mean that there are no drawings or information about the pattern of the mounting holes. All you got is the threaded holes which the part will be screwed onto later. Then these are gold - you screw them into the mounting holes, put whatever you'll mount over, and give it some decent hammer action. The hardened tips then make some nice dents where you need to make the mounting holes on the new part. I guess they are not measuring devices as such, but they do away with the need for measuring altogether. That way the lack of documention can be passed on to the next poor smurf to come along next time.
Thanks for the pics, they are (both tools and the photography) really nice!!!
That's some sweet kit, Vidar!
You have some really nice stuff yourself up there in the thread I see!
From 6” to 100’ Theres 11, 12 if you count the workstation mat which has come in handy at times, I used that scale ruler throughout 7yrs in schools, I had a aluminum one but it disappeared, you can see it’s little baby brother underneath it, that faxmax and stick ruler have seen the most field time, but for the last 10yrs the only ones that have been used are those rulers or that dinky plain 12ft tape measure..JR

That setup will take care of most measuring scenarios.
A lot of my gear is old-school. It doesn't quite measure up to your precision kit.
A few from me , had it not been for this thread i wouldn't have noticed rust starting on a couple of them (Image removed from quote.)
Quote from: gerleatherberman on January 07, 2019, 07:18:53 PMA lot of my gear is old-school. It doesn't quite measure up to your precision kit. Old-school still in use tend to work very well. I think of it as designs that have proven themselves over time. Not to mention that many old tools seem to have superior build quality compared to many of todays price cut minimum viable options. (I guess there is a bias there as those well built tools are the ones still around and in use - the price "optimized" tools of earlier are simple not around anymore..?) As for the precision I think it is simply more a matter of different tools for different work. We tend to get what is best suited or needed for the work at hand. (I think some of those precision tools would be quite useless or ineffective working with wood for instance). I hadn't seen those foldable caliper rulers before I saw this thread with you and Cody. Those were interesting. What is the dial meter next to your micrometer?
