Gem Steam Machine.

by hansmeevis on January 23, 2012

Here is something a little different.

This in my completed  oscillating steam engine. Basically, steam or compressed air enters the bottom silver pipe on the left of the picture, then travels up the lapis lazuli support, into the jade cross support.

Then the air enters the cylinder and pushes the sugelite piston down, spinning the flywheel.

The spent steam exits the silver pipe at the top of the machine.

Base and cross support is made out of Nephrite jade from Canada.

The cylinder is made out of Brazilian quartz. The top is closed with Australian chryoprase and Zimbabwean aquamarine.

The piston is made out of South African sugalite from the western Cape and the conrod and upright supports are made out of  Red jasper from Pilgrims rest in the Eastern Transvaal, SA. ( that’s where I found it) The front upright is also made from Lapis lazuli from Afghanistan. ( That is where the air runs through.)

The flywheel is made out of black Chalcedony, and the two shafts from Smoky quartz and Rose quartz  from Namibia.

The crank is made out of a lamination of Sugalite and Chrysoprase.

The three washers are made out of clear quartz, blue lace agate and pink Botswana agate.

I first made a machine out of  window glass, to prove to myself if the concept was actually feasible. I figured that if it didn’t work, no big loss.

It ran well so I felt confident that one made out of stone would work.

One of the problems was that I wanted the flywheel to be removable, so I made a jade woodruff key that slotted into both the flywheel and the flywheel shaft.

Another view. The washer and cross support were also slotted thus allowing the shaft to be removed.

The top view showing the various washers and the inverted aquamarine that acts as the cylinder head.

There were quite a few miscalculation during the construction.

As I was trimming off the Rose Quartz pivot, it snapped off. This was because I was trimming it on a worn 1200 lap, and it set up a high pitched squeal for one nano second. The sound propagated up the quartz rod and shattered it at the end.

This is not the first time this has happened to me.

A couple of years ago, I carved a ring out of solid quartz. It was completely finished, except for the top which I wanted to be flat with facets on the side. I mounted the whole ring in my Imahashi gem cutting machine and cut all the facets. As I started polishing the top of the ring, is set up a squeal and BANG!, the whole ring exploded into millions of little pieces. They were scattered all over the workshop.

No problem, I had enough spare length so I ground the broken piece out and refitted it.

I put up a video on you tube of it running

Three Stone Pavé

by hansmeevis on March 7, 2011

Here I have drilled the holes using a 2.1mm Ball burr. This picture was taken on my bench so the lighting is a bit miff. But I am setting .03ct diamonds into 18ct gold.The  flat tri-angle in the middle of the holes will not be enough to spread over the three stones.

So then I take a .75mm flat engraver and dig in from the three sides to form three little pillars. Difficult to photograph. But now I have enough metal to form a spread with my beading tool. ( no 9, by the way.)

But first I level my stones and use an ongolette no 4 to raise a bead on the opposite side of the stone. This is to prevent the three stones from sinking in the middle when the ball is formed. ( This is just test stuff, remember. I am not trying to win competitions……)

Then I use my No. 9 beading tool and form the three little pillars into a ball.

Bingo, there is enough metal now to spread the ball comfortably over all three stone and they form a perfect ball.

So this is the method I have worked out, and it seems to work.

Not saying it is the correct one, but hey, I would love to see, not hear, of a better one from one of the pro setters on Orchid.

I said see, not hear.

Keyboard goldsmithing is easy.

Temporary Picture

March 4, 2011

Like I said in my post, it’s more the flashing of the bead that holds the stones in. This one I moved the stones a little bit further apart, but the ones with the stones closer together is no better, because then the center bead become proportionally smaller.

Making a Titanium Anti-Clastic Ring with Fused Gold Sides

February 26, 2011

Up to pre-setting I start by cutting a piece of titanium off a thick slab that I bought from an industrial machining place. I went there once and there was this guy that sold me the most amazing off cuts for a very good price. It was something that I have worked with for the [...]

Chains

February 20, 2011

A gold and titanium wedge link chain. One meter long. If I say that this kind of chain is a lot of work, trust me, it is. I worked on this chain until my fingers literally bled. ( from the buff stick constantly rubbing against my thumb ) I stagger work of this type over [...]

A Ring, a Pendant and some Experimental Stones

January 29, 2011

Here is a somewhat radical ring, as per my customers design. The center diamond is a 1.16 colour G pear that is loose and dangling. Then the smaller diamonds were set in a “scattered” manner ( her words). And it came out very nicely and suits her style perfectly, she being tanned, slim and very [...]

An Aquamethyst and a Drilled Diamond

January 21, 2011

Here  is a composite stone I made out of aquamarine and amethyst. coming in at 3.6 carats.  Blue and purple make indigo and this stone certainly reflects that when it is viewed in natural light. Hassle with photographing this stone is that on the one side the amethyst is not purple enough and on the [...]

A Ring, a Stone and a Prize

January 17, 2011

This is my latest Aqua ring. I like carving beryl. It polishes easy and if the colour is good, as in this one, it resembles  flowing water. Also, the nice part is that they sell well, ahem….. I cut the sapphire in a standard brilliant cut. It comes from Aussie and, like the aqua is [...]
