For the love of the EU Brussels cockroaches

power-faliure

UNPRECEDENTED! 

We had our first power failure in three years the other day.

This contrasts strongly to the 165 documented power failures we had in St. Maarten during the course of one year.

So just in case another disaster like this struck my workshop and kept me out of the work that I don’t have, I made an emergency plan.

BEHOLD!!!

The potato battery.

In keeping with Brussels directive that all new vacuum cleaners above 1600 watts are now banned from all EU countries, I too have gone green with my emergency power supply.

We all have to do our bit and save energy and I, as a good EU citizen, will also do my part.

And just to keep things in balance, I invented the self raising table.

This table is unique in it’s design by using only GRAVITY to work.

And gravity, as we all know, is free and green.

This is a vast improvement to the standard table which uses the quaint and now obsolete four leg system.

It is important to be green these day and in keeping with our new  Brussels ruled society, I urge all the readers to start using solar power cells.

If everybody started using solar power, they would drain the sun of heat and we would solve global warming in one fell swoop.

So do your bit and help Brussels at the same time.

It’s the right thing to do.

Seagull Pendant.

Titanium Seagull Enamel Pendant

I finished this painted enamel pendant the other day.

I like the porthole look.

I hot forged the titanium into a circle and the filed the hell out of it.

 

Seagull Ocean Spray

Here is a closer view.

Eventually I tilted the rocks upward. I thought it gave more a feeling of speed.

IMG_9484

I pierced the seagull out and soldered a locating pin to it.

Then I drilled a hole in the pendant with a diamond drill.

A little while ago Vasillie and his partner walked into our shop.

He was asking if I had any setting work for him.

We got talking and it turns out he is a Russian master setter and when he showed me samples of his work I was blown out the water.

So then when he saw my gem cutting machines we made an agreement.

He will teach me advanced setting and I will in turn teach him gem cutting.

IMG_9534

Being a setter already, he has the ‘touch’ in his hands, so he picks up the techniques without destroying the stone very quickly.

IMG_9531

With his partner Olga.

He was trained using traditional setting techniques and then he had to relearn  to  change over to microscopes and the graver max power machine.

So once and for all he was able to set up my equipment properly.

I was taught the basics of setting by Shane, my journeyman, and everything after that I self taught.

So it’s very cool to be taught by a dinkum honest to goodness pro setter.

I have learn’t a LOT of finer techniques so far.

IMG_9619

We even went for a tjop and dop in the park one afternoon.

You got to figure:

Between the four of us we speak six languages and we had trouble communicating, with German being our base language.

You can never speak enough languages.

A couple of Sundays ago Anne and I went for a 60 kilo cycle to a swamp area around Dusseldorf.

I was a rare beautiful day, no wind and mild temperatures.

IMG_9508

We got all our ducks in a row, too.

IMG_5812

The Germans were out in force playing  Pétanque, which is like grown up marbles with steel goons.

They take this shit seriously here and an entire weekend is wasted dedicated to it several times a year.

What really freaks me out is that youngsters play it as well.

Enamel Painting. The Learning Curve.

 

1-(61)bw1

So this was my photo shop clean up.

I then shrink it to fit the size I am going to enamel.

IMG_9179

I make three.

Now before, I made the paper black with pencil lead at the back and then traced out the design from the front.

It works OK, sort of.

But I had not tried  the “traditional” way.

That is using a pin or needle to prick the design through tracing paper.

This took a couple of attempts and even then, the next one will be better---unless I figure out another way.

Because this way is a serious mission.

Far to much PT.

IMG_9182

Then I cut out some tracing paper the right size.

It’s quite a heavy type and I stuck it to some paper.

IMG_9183

So it can hinge up.

At the back is a pencil that I inserted a cut off needle in, to prick through the tracing paper.

IMG_9187

And then I stuck this to a small piece of glass, to stop the needle at an exact distance in.

At first I just did it on another piece of paper, but then the needle goes in to deep and the holes become to big

IMG_9191

The needle make tiny little holes through the tracing paper, all equal size.

IMG_9193

After the tracing paper had the design pricked in, I stuck it to the enamel.

IMG_9195

Then I made some lamp black oil.

IMG_9196

Once the soot from the candle is scraped together, oil is added until it’s like printing ink, kind of thick.

IMG_9197

This was my third attempt and it was just workable to accurately get the outline down.

In the instruction I read from -----  they say that if the first attempt to force ink through doesn’t work, just realign and do it again.

But my holes close up, so I probably am using a wrong tracing paper maybe.

 

IMG_9198

This is a simple design.

For a complicated one, there has got to be a better way.

______________________________________________

Then I found one.

IMG_9280

I took some lamp black, made it into a powder and then rubbed it onto the back of the transfer paper.

I stuck the front to a Post it note so that the transfer wouldn’t move around.

IMG_9281

Ta daa--- I signed my name on the front and it worked perfectly.

I am going still do some experiments with actual carbon paper, see  if it burns out.

(Later). Yep, burnt out completely.

Anyway, this is the twin of the first blank that bubbled.

IMG_9213

I re-fired this enamel blank before I started the actual painting.

Just to make sure that the two layers were homogeneous.

IMG_9215

This time I left the background last, what with the yellow colour change over many firings.

IMG_9217

This one was much more orange before firing and the brown was not nearly so pronounced.

IMG_9219

About halfway and then I decided this project had gone far enough and I scrapped it.

LATER:

IMG_9611

I received some clear enamel from a supplier in the UK and I  tried it out on my dragon and I also simultaneously made a gold star and drilled a hole in it and fused the whole caboodle together.

Worked too, no mean bean bubbles came up but it is still a reject, so it is thrown on the rubble mountain of Hans’ failed attempts.

Fail

Tool Making

IMG_9468

I made this nifty ring clamp for myself after I saw a similar clamp being used by a Russian master setter.

I have got the proper GRS inside ring clam but it only expands from one side .

I don’t like that much because it puts expanding pressure on only one side of the ring.

And anyway, there is absolutely nothing I like more than making gizmo’s and tools.

IMG_9457

Components.

The center is a black nylon bush that has a cone on both sides.

The two brass cone shaped washers that force the nylon open when the two stainless steel screws are tightened.

This stuff all turned out on my cheepo Grizzly lathe.

 

IMG_9462

Then, once you got the ring tightened up nicely the setting ball gets tightened and the whole gizmo tightens vas.

This is great for setting eternity bands, because once the ring is tightened, turning the ring around is a matter of loosening the setting ball, not the ring clamp, as in the original GRS equipment.

As with a large part of the jewellery industry, the bar is constantly raised by new techniques and methods that are developed.

The GRS system, a microscope and the Gravermax or Lindsay Air  assisted power engraver have become the accepted norm for those craftsmen working on that level.

In the old days, I had a ring clamp, some gravers and a Optivisor and that was good enough.

These days the retailer wants stones set so that at 30 X magnification the job is flawless.

That is  not possible with an Optivisor.

Simply put, if you not at the setting skill level with that equipment , you get no work.

 

IMG_9470

Here is another cool little tool I made myself.

IMG_9473

A tiny isty teeni saw.

For azure work and OCD corner cutting.

IMG_9474

I made the frame out of brass and the screws and nuts out of steel.

The threads are 2 mm M2 standard.

IMG_9477

One of those tools you like making and then only need it twice every eighteen years.

Tjilip,( I’m the BOSS) ,  doing his thing.

Making a Ring out of Titanium Plate.

 

IMG_9397

A customer sent me a 2 mm thick titanium plate.

He wanted to have me make a wedding ring for himself.

I had enough material for two attempts.

IMG_9398

So drilled a hole.

IMG_9390

I knew the about size of the hole to start with, because I tested it on a couple of washers before.

The one on the left was a bit small and the one on the right went off my triblet.

Got it.

IMG_9399

I cut it out with a hacksaw.

A hacksaw blade is quickly in-sy- moer in if you don’t oil it.

I use SAE 30 – best oil around.

 

IMG_9401

Then I saw the corners off and anneal it, and then I take a vise grip and grind it to a rough round.

The  reason I anneal it only now is because I don’t know what alloy this is.

And sometimes unknown alloys screw up big time after annealing.

So rather a small washer than the whole plate.

IMG_9404

One does not just ‘dome’ a 2mm thick washer with a smack or two.

Anne held the flame, and I heated up the washer and when it was good and hot, I dropped it into the doming block and then smacked it with the punch and hammer.

When titanium is red hot, as in pale orange, it’s about as malleable to me as iron is at that temp as well.

IMG_9406

The shape of the washer after doming.

I only use the doming to start the triblet part.

IMG_9413

One does not just  ‘ bash’ a titanium washer up and flat.

Anne holds the torch, I cook and bash.

It looks bad on the triblet, but I cool it often under water.

IMG_9412

That colour is malleable.

You can forget hitting this alloy up in a civilized manner it it’s not red hot.

IMG_9407

Eventually it gets to here.

Then I use the bench grinder to true it up

And I also hammer it further until I get it  to the right size.

The center start hole size will determine the sweet spot.

That is where the ring hits 90º and is the right size.

The washer before gave me a good estimate.

 

IMG_9411

Finished.

Center matt, polished bevel edged and comfort fit on the inside.

Other than the hardness factor it worked as per.

Cool or what?

Two more titanium and gold and silver pendants I made.

Diamond in gold, white gold and copper.

IMG_9244

This one looks simple enough but it is actually very tricky to make.
