In this video we answer the burning question of just how thick a standard Sanford Sharpie mark is. We use our high resolution Johansson indicator and some gage blocks to take precision measurements of Sharpie thickness.

Great, now I'm going to be paranoid about cleaning off my layout marks. Definitely makes sense. We have to deal with the thickness of ink on paper in the printing world. A flat 4 foot tall stack of paper going into a press can be half a foot taller on one side coming out if there is more ink on that side. We have to use shims to keep the stacks level. Great video.

Tom, Interesting methodology there! Traditionally, some inks have been similar to shellac - india ink in particular - and the pigments are ground extremely fine. Dykem is a lacquer product, and the pigments and binders in lacquers quite typically run to ~3 mils dry film thickness (0.003" DFT) Your industrial painting coatings generally start at 3 mils DFT, and can get quite thick - we've specified some coating systems at work that ran to ~10 mils (~250 micrometers) after 3 coats were applied. Needless to say, the guys in a paintshop aren't using the same kind of gauge that you demonstrated, but their QC instrument calibration people may very well do something like this... Cheers! Eric

Looks like each thickness is a function of the viscosity of the carrier fluid, minus the volatile solvent. The thicker ones leave a thicker residue after drying. The better the coverage of the dye, the less viscous the carrier needs to be, therefore the residue layer will be thinner after drying.

If it’s anything like a dial indicator , There is the stylus part, which touches the object to be measured, and on that stylus, further into the measuring device , there are teeth on it that mesh with a cog/gear. As the stylus moves upwards, the gear rotates into a bunch of reductions and is kept in tension by a small spring resisting the rotation of one of the gears in the system. At the end of the gear train , one will be connected to the little arm that indicates the position against the background There could be many styles, but this is one style I have seen in a cheap dial indicator. Maybe it’s more refined in something as precise as ten millionths of an inch !

Interesting experiment. Friendly question... Tempature being vital, how can you justify dropping your variable test gauge into volatile solvent and quick dry with a compressed air can (both chilling the gauge)? Why is this not done to the verification gauge? Not follow the same thermal process, the verification gauge is no longer valid for this experiment.

I truly enjoy your videos and shall continue to watch and wait for them.Thanks for making them

Nice video! But at 4:30 the 0.0001" is 2.5 micron, not 25, if I get the math right. This reflects the general problem with imperial units: it's easy to make mistake when talking 1/1000 vs 1/10,000 on an inch, but it's harder to mess 2.5 vs 25 micron. Please, please, use metric system, people...

Fancy bit of kit that no one seems to want let me near. Once while I was grinding a thing and was curious how thick a sharpy mark was I ground the surface I was working on, took a few extra really light passes and spring passes. Then backed off a thou, sharpied the surface, and snuck up on it about 0.0001" at a time. Got down to 0.0002" with no change then noted it go from black to grey on the 0.0001" pass. Another pass at half a tenth and it was still barely visible. Huzzah for science, confirming findings via a variety of methods. Thanks for adding dykem to my repository of knowledge.
