Picked up a Harbor Freight thickness gauge to measure Thing-O-Matic filaments and suchlike; it has a plastic piston and anvil, so it’s not well-suited to measure anything other than plastic parts. In fact, it’s all plastic and the various sliding surfaces produced a remarkable amount of friction.
Fortunately, the back cover pops off without too much of a struggle:
Dabs of silicone lube at all the contact points considerably improved its disposition.
The display offers 0.01 mm resolution, but I don’t believe that rightmost digit for an instant. The stated accuracy is ±0.1 mm, which is probably closer to the truth, and it agrees reasonably well with my considerably better quality digital caliper.

…so why not just use the calipers?
Also either my reader or your RSS feed is broken since a few days ago…
Also Also the PCB link in the previous post is broken. :)
Uh, because now I have another tool… [grin]
I’m laying odds on your reader being defunct, because the number of “subscription” hits per day hasn’t changed by much. In any event, there’s absolutely nothing I can do about it, because WordPress handles all the infrastructure.
Ditto for the PCB link: they’re all working fine. I have noticed that sometimes images don’t render correctly the first time through, which is (almost always) cured by refreshing the page.
ahh, modern technology! :)
(But the first link in that post is still broken here: points to https://softsolder.com/2011/12/02/gpsvoice-interface-for-wouxun-kg-uv3d-pcb-in-box/ when it should be

Turns out I was looking in the wrong place. Got it!
Thanks…
