Seems like they’re asking for the Tyler Durden “refinement”.

Yup, they’re just lightly pressed into a tapered hole. You just have to turn them with a greater force than the string exerts on them, and ideally they stay put after you let go of them. Works well for gut/synthetic strings, less so for steel strings because those lengthen very little so friction tuners would be too imprecise.

Like linseed oil and caramel.

I’ve just bought it roasted. It was originally intended for billiard cues.

Edit: sorry, I missed the joke. 😅

Honestly, I don’t know. I didn’t expect to see literal air bubbles rising from the wood in the oil bath. That’s a lot of oil, so I expect several months for it to fully harden. Maybe I can speed up the process with an UV lamp.

I wonder how doctors could compare this simulation to a real surgery. I’m willing to bet it’s “realistic and lifelike” in the way a 4D movie is.

I think “lifelike” in this context means a dead human. The robot was originally trained on pigs.

You can make a mold for a keycap stump and stem cavity, make a resin cast, then glue the keycap on. Maybe you can modify this: https://github-wiki-see.page/m/imyownyear/Z-Butt/wiki/Z-Butt-Mold-System

Yes. It prints similar to an inkjet printer, but the inks are UV-curable. UV inks don’t need a special medium like coated inkjet paper, they stick to any surface. You can also layer multiple coats on top of each other to create reliefs (like resin printing, but with colours)
