1:1 -Forstner Bit = round wooden sticks
title should be "makeshift lathe jig"
Since he drilled all the way through the wood, there's nothing in this build that required forstner bits (which are for making flat-bottom holes only partially through wood).
still cool though.
Infinite Loop and Drag Race Battery Test
from this video: https://www.youtube.com/watch?v=7jqImhd8Ggc you can see that he's coiling copper wire around a pipe (using a lathe to save time).
What are the copper coils usually used for? Pipe heating?
Diamond turning an acrylic dome for an underwater camera
The dome is spinning on a lathe, while the diamond cutter, takes off a this layer, removing the translucent outer layer, leaving it clear.
talk about satisfying video. but what is going on here?
Hypnotic Metalworking
I have to assume what they made @9:36 was just made for showing off what was possible with the Lathe. I want it so much to be an actual component for something really cool.

Building a lathe from scratch
The bow lathe might be good in that situation too:

Well that is *quality work. If I'm ever in a fight with a rock monster, I can now form some sort of rudimentary lathe.

Thanks
If you're ever in a fight with a rock monster, perhaps a bow lathe would be quicker and easier to get up and running - http://videosift.com/video/Moroccan-Bow-Lathe (you still need the chisels though)

supreme skills - tops
I think you still misunderstand. I don't mean it would hang from above, it would balance on it's contact point. In that way, it would 'hang', but the point of contact would be pointing down in contact with the top of the 2cm cylinder and the bulk of the mass in a ring hanging below that point. To exaggerate for clarity, think of a soda can with the top cut off, turned upside down, and balanced on a pin touching the exact center of the inner can 'bottom'...then spin it.
My idea is a top EXACTLY as they made it, except the weighted ring is much lower, so the CG is below the point. Then, when set on the pedestal, it would be stable when stationary (when set on a counter, the point would not touch). I can't see why that would change when spun as long as the CG stays below the point and balanced/centered.
It would balance when stationary, no question. My only question is what might happen when you spin it, would the rotation make the CG 'want' to be above the contact point for some reason, or would nothing happen. I don't have a lathe to make one myself to try, so I thought someone well versed in rotational physics might know.
@newtboy I think you are right if the spinning top would hang, ie its tip would be inverted (pointing upward, stuck to the plateau in some manner). Any movement away from center for the CG would be pulled back by gravity. No spinning required. However that is not a spinning top but a pendulum. As long as the tip is on top of the ground (pointing down) and not hanging the spinning top will be unstable and the only way to balance the top is to spin it no matter where the CG is.
Cubes in a cube
The hot glue holding the parts so they don't fly apart at the moment the final cuts release them was inspired.
...or it's just what you do on a lathe, I'm not knowledgeable on lathing.
Who knew metal milling machine could be such fun?
I work in a CNC machine shop programming lathes. That isn't aluminum they are machining. It's definitely steel, probably 4340.
Carbide inserts are more than capable of cutting metal without coolant. Well formed chips absorb and carry most of the heat away. You start to run into problems with gummy materials (like aluminum) that form a built up edge on the cutter. In this case high pressure coolant can be used to help break the long stringy chips and keep them from sticking to the insert.
One case where using coolant can be detrimental to tool life is when machining a part with an interrupted cut. Think of sliding your finger over a surface with a bunch of holes in it. Your finger switches back and forth between making contact with the surface and gliding over empty space. In the machining world, this motion would cause abrupt transient temperature changes, and coolant can sometimes exacerbate the problem and cause the carbide insert to crack or chip.
(pedantry) I would hesitate to call that machine a mill. You can see the machine switching freely between rotating the part to provide the cutting force (turning) to rotating the tool (milling). It's more akin to a horizontal turning center with a milling spindle built in as well. Pretty awesome stuff! (/pedantry)
Making a Huge 300mm Sphere out of a Log
As far as wood lathes go Mordhaus, this one shown here is one you'd find in an enthusiast's home shop or a light industrial shop-Had one in 8th grade wood shop that was a bit more formidable that this one that you could have mounted a larger round of wood upon with a much larger electric motor with way higher RPM's.
Love to try a couple of solid wood or other spheres for some speaker enclosures-Always coveting an industrial lathe.
Check this one for scale:
