The Chinese usually work these mills for about eight hours per day. A shovelful of quartz is first thrown into the mortar and the mill is then worked by the foot of the miner, who stands on one or other of the stones shown in the drawings, grasping the uprights or else a cross-bar that is sometimes fastened across them.

When the quartz is supposed to be crushed sufficiently fine, the hammer-head is propped up, and the crushed stone is scraped out and sifted through a circular sieve 15 inches to 20 inches in diameter, and about 1J inches deep. The sieve itself is made of thin strips of rattan about 0.1 inch in width. There are from 36 to 40 holes per square inch, so that the width of mesh varies between 0.04 and 0.06 inch. A man can crush in a working day, with one of these mills, from 70 lbs. to 140 lbs. of stone, according to its hardness.

When Cody Wilson revealed the worlds first fully 3-D printed gun last year, he showed that the maker movement has enabled anyone to create a working, lethal firearm with a click in the privacy of his or her garage. Now hes moved on to a new form of digital DIY gunsmithing. And this time the results arent made of plastic.

Wilsons latest radically libertarian project is a PC-connected milling machine he calls the Ghost Gunner. Like any computer-numerically-controlled or CNC mill, the one-foot-cubed black box uses a drill bit mounted on a head that moves in three dimensions to automatically carve digitally-modeled shapes into polymer, wood or aluminum. But this CNC mill, sold by Wilsons organization known as Defense Distributed for 1,200, is designed to create one object in particular the component of an AR-15 rifle known as its lower receiver.

Subversive ambitions aside, Wilson doesnt hide the fact that the Ghost Gunner is also a money-making project. Unlike Defense Distributeds 3D-printing projects in the past, Wilson says selling its own CNC mill offers his group a way to fund its activities. He considered offering pre-orders of the device through an Indiegogo or Kickstarter campaign, but both sites terms of service dont allow the sale of weapons or tools for making them.

Fundamentally what occurs in individual crystals and in the lattice structure is the same for all stresses. The changes on a larger scale, in the whole sample, for example, are dependent on the method of deformation being used. Forging is different from drawing, and bending is not the same as riveting. Because the effects of stress at the crystal and grain level are the same, one example will sufice for all forms of deformation. We8217ll use rolling to illustrate the process.
