#Caliper
Changed the rear brake pads on the #CrossGolf. Bit of a struggle getting the low profile bolts off on one side. Someone had already tried and mangled them and either given up or put the mangled ones back (they cost cents, grr).
Disc is fine. Guide rods lubed (they needed it).
But there's also some problem with the handbrake not 100% releasing pressure on the piston. Which, after some research, appears to be a common Volkswagen problem with those calipers where the lever/shaft on the rear gets stuck with rust.
So either rebuild the caliper (need at least a super deep locking ring pliers and seal kit) or just buy new caliper (aftermarket not nearly as expensive as I thought).
And a bleed kit (or cowboy it).
Grumble.
and others that don't as well as inside diameters of the hose on the CAC side ( which you can't get unless you strip the car as if you would to replace it ) and on the flap-air intake so if you need the part numbers, to check the part(s) before buying it, with a #caliper on hand, feel free to reach out.
Also depending if you have the one with the hole in the hose to fit the boost pressure sensor or if like me you have the sensor on the intake manifold after the flap-air intake.

@mrpablington @Azurakumo Trying to slam through the #Destiny2 Season of the Witch pass before #Starfield launches on the 6th.
#Caliper, this odd little platform game I got on #Steam for a buck
I might try to dip back into #Everspace even tho it crashed on me as I finished the first sector, but before the achieve popped which is never a good look for a game, even if it's a roguelike.
I found the instruction sheet for a manual #caliper and it has this picture in it. In Italian it says something like "Drawing centers". Does anyone know what they mean by it? Am I about to unlock a new way to use a caliper?
Today's oddity: showed an actual degreed and employed #engineer how to use a cheap #Vernier #caliper to get accurate measurements down to 0.1mm.
Caveats: engineer is much younger than me, this was an old-school caliper without a dial or digital readout, their primarily field is fluid dynamics (so not a lot of calipers). And they understood the idea quickly.
But now I'm wondering this person would panic at the sight of a #slideRule. Tempting to throw one in the bag "just in case."

In other news: I bought a #Mitutoyo #caliper, which should be a once-in-a-lifetime investment (after spending too much money on cheap, uncalibrated knockoffs in past years).
I'm using it to design for #fdm and #sla #3dprinting, and #lasercutting.
Cheap Caliper Hack Keeps ‘Em Running Longer
Many a hacker is a fan of the cheapest calipers on the market. Manufactured in China and priced low enough that they're virtually disposable, they get a lot of jobs done in the world where clinical accuracy isn't required. However, their batteries often die when left in a drawer for a long time. [Ben] was sick of that, and got to hacking.
The result was a quick-and-dirty mod that allows the calipers to be powered by a AAA battery. The average AAA cell has 5-10 times the capacity of the typical LR44 coin cells used in these devices.
[Ben] whipped this up with an eye to making it work rather than making it nice, so there are some shortcuts taken. The battery housing was 3D-printed on the lowest-quality settings that were viable, and it's held to the calipers with hot glue. Similarly, bare wire ends were used instead of proper contacts, taking advantage of the battery being crammed in to make a good connection.
It's a hack that will likely save [Ben] much frustration, as he'll now rarely open his drawer to find his calipers dead. However, one [Pete Prodoehl] suggests another useful trick: store the calipers in the closed position with the lock screw tight to save them turning themselves on accidentally.
Whichever way you go, you've hopefully learned something today that will keep your cheap calipers working when you need them. Next, you might consider hacking them to capture data, too.
Printable Caliper Jaws Increase Precision, Deflect Derision
If you've watched as many machining videos as we have, no doubt you've seen someone commit the cardinal sin of metalworking: using caliper jaws to scratch a mark into metal. Even if it's a cheap Harbor Freight caliper rather than an expensive Starrett or Mitutoyo tool being abused, derision and scorn predictably rain down upon the hapless sinner's head.
The criticism is not without its merit, of course. Recognizing this, [Nelson Stoldt] came up with these clamp-on nosepieces designed to turn calipers into a better marking tool. Using stock calipers as marking gauges always introduces some error, since the jaws are equal lengths and thus have to be held at a slight angle to the workpiece in order to make a mark. The caliper jaws correct for this admittedly negligible error by extending one jaw, allowing it to ride on a reference face while the other jaw remains perpendicular to the workpiece. As a bonus, the short jaw has a slot to mount a steel marking knife, saving the caliper jaws from damage.
[Nelson] chose to 3D-print his caliper jaws, but they could just as easily be milled from solid stock to make them a little more durable. Then again, you could always 3D-print the calipers in the first place, and integrate these jaws right into them.

3D Printed Calipers Work like Clockwork
Most of us use calipers when working with our 3D printers. Not [Albert]. He has a clockwork caliper design that he 3D printed. The STL is available for a few bucks, but you can see how it works in the video below. We don't know how well it works, but we'll stick with our digital calipers for now.
The digital readout on this caliper is more like a sophisticated watch. A window shows 10s of millimeters and two dials show the single digits and the number after the decimal point.
While we can't validate its accuracy and we imagine it would depend somewhat on your printer's abilities, we can say it looks pretty amazing in operation. This would be just the thing to be in a movie about an alien or post-apocalyptic machine shop.
Like a real set of calipers, there is a depth gauge, although watching it spin through the measurement is a lot more entertaining than the usual measurement. Towards the middle of the video, you can see the parts involved. As you'd expect, the main part is a rack with pinions driving gears that move the numbers and pointers.
Probably not very practical, especially when a reasonable set of calipers doesn't cost very much anymore. But great fun and would make a nice show project for your 3D printing skills.
We have to admit that these calipers would be easier on batteries than the pair we use every day, but then again there are other ways to solve that problem. If you want a crash course on how to use calipers to reverse engineer mechanical parts, we can help.
