Ford #4(ish) Viscosity Cup

thingiverse

When I found the price of these online, I knew immediately I wasn't gonna be buying one. It's a viscosity cup. A sort of de facto and ubiquitous, "Ford #4". I found the dimensions online, somewhere. USAGE: Hold handle with cup hanging below. Fully submerge cup into liquid to be tested. Raise out of liquid, starting stopwatch at the absolutely precise same time. :p Observe liquid draining and stop stopwatch at first break in flow, generally watching about an inch below the outlet nozzle. Note the time on stopwatch. Time is just right? Goldie Locks would be pleased! Too long? Add thinner. Too short? Remove thinner (hmmm! :p). Now it's back to dunkin' and timin'. You're ready to "whatever". I use this for spray paint viscosity, at somewhere around 20 seconds. Fusion 360 design is shared at this A360 link Oh and err, by the way ... ... in case it needs saying, do NOT try to use this in liquids that react with whatever you fabricate it from! I use it for waterborne paints only.
