How are these stones cut and machined?

i saw the documentary... they think it has somehow to do with aliens..

daghan pa kaayo mga rock formations nga unexplained on how it was brought there etc...

yeah but lets not entertain that idea here.this thread might be closed or is on its way to be.hehe

they are done by ANCIENT ALIENS

Alien stories are not allowed in this thread.

It is a current unanswered question how these stones were cut. Let us put aliens in movies lang.

time and effort bro.. makes wonders...

nag masonry work man gud ko karon mao nakapangutana ko ani sa mga scientison diri.. na try na nako palit mga diamond blades sa ACE ug sa sa ubang hardware stores, pero dili man ko makahimo ani cutting sama sa puma puncu. curious lang ko.

No one exactly knows the answer at the moment. It can range from molding (an ancient form of concrete), or plain and simple uncanny accuracy in the hands of those ancient masons.

However...I suspect this is not the main reason why a post like this has begun to surface again in this section of iStorya.net...some people are testing the waters once again...so before this subject turns sour, yet again...

"...just because it was Jack's shirt that was stolen doesn't automatically imply that Jill was the one who stole it."

Ergo, if anyone ever mentions anything about ancient astronauts, aliens or time travellers in this thread, I'll close it without batting an eyelid. Don't turn the Science section into your afternoon entertainment galore variety show.

.. you can't mold a granite easily bro.. it has a melting point of 1500-3500 F, can a stone age human create a device "furnace" that can reach that temp. i dont think so.
im from an machining industry and i know how tough this stones are... wala mo sokol ani..

naa ni reply nga time and effort,
do you know how old this stones are?..
do you know how hard this stone are?
do you know what materials that can cut these stones?
Drilling just 6mm deep with this stone would take much time if wer talking about those times.. have you seen 10,000 BC? imagine that people! can they?
and wala pay record nga naay mastodon (stone age elephant) in Bolivia.

the best answer is " We don't know "

The ancients didn't cut or lift mega tons of stones. They MADE the stones!.... in other words, they are man-made stones. check this link Ancient Megalith Construction

interesting. thanks for sharing

Here is a theory by Ivan Watkins, a Professor of Geology, Department of Earth Sciences, at St. Cloud University in St. Cloud, Minnesota about ancient stone cutting...

Watkins explains that soft rock is easy to cut; granite and the other hard igneous rocks are difficult. Granite contains 15 to 30% quartz crystals, and a few other minerals of varying degrees of hardness, which is important when viewing the signature marks left in stone under the microscope. The methods that are supposed to have been used by the ancients, such as pounding, hammering, grinding, polishing with abrasives, and wedging, just don't match up with what Watkins sees under the microscope.

What he sees, in the case of hammering, is rock wanting to break along pre-existing planes of weakness. When river sand, which is mostly quartz, is used to grind and polish rock with quartz, the softer minerals in the rock are sanded out, while the quartz crystals, little affected, are left standing above the rest of the minerals on the surface. In the case of wedging rock, Watkins finds the absence of low-angle fractures, and no ability to control the cracking of the rock. On a surface worked with pounding stones, all the minerals are unevenly fractured.

All of which is incompatible with what Watkins sees with Inca stonemasonry. What he does see on some Inca stones are slick surfaces, at Machu Picchu and Ollantaytambo, and the Rodadero at Sacsayhuaman, still used as a slide by children. Similar to a ceramic glaze, heat can melt quartz fragments into a glaze that fills in irregularities, creating a smooth surface..

In an effort to discover just how such surfaces could have been obtained by ancient cultures, Watkins went looking for modern technology that produces a similar signature. He found an important clue in the work of geologist David Lindroth, at the US Bureau of Mines, Twin Cities Research Center. Lindroth was using 100 watts of light energy, focused to a circle of 2 mm, to cut through any rock, in a process called "thermal disaggregation." The cuts were only 2 mm deep, but repeated passes can cut through rock of any size, he reports. Quartzite fragments quite easily with this process while basalt melt. And, he concludes, Inca stone surfaces are similar to those that have been thermally disaggregated.

ai nako wala ka.. kuha sa idea mego.. try google+granite+mold+melt or what so ever.. granite is not man made mego... dili na hallow blocks nga e die cast lang nimo.. you need a furnace nga mo abot ug 3000degF.. nya sad to say wala pa ing ani sa stone age... nya usa pa.. kita ka sa pictures naa mga drill holes ug slots nga perteng ka precised.. even ang usa nga bang-gietang machinist dili ka kuha ana.. nga dili ma tipak ang granite.. kay perteng kagahi ana ug ka brittle.

According sa theory, The ancients developed a substance or acidic juice that can melt granite and turn them like "clay". and this is a forgotten science and this can prove how they lifted and formed granite stones. And naay proof kay naay isa ka side nga naay agi ug wood na mura ug "clay".

Man-made stones theory can explain everything from lifting and forming stones including granite.

the holes are precision 6mm not 5 not 4. ISO standards na tingali to sa karaan pa.
