Computer speakers – uFonken

It’s been awfully quiet here, so an update is in order. I haven’t done much engraving in the meantime, but some other interesting stuff is in progress. More on that at later time.

But now I can present my new computer speakers – wonderful little uFonkens from Planet 10 HiFi Fonken family. Speaker elements in these are Fostex fullrange FF85WK‘s.

Enclosure is made of birch plywood and veneered with walnut burl. Looking wonderful and sounding very good with vocal music. But they do need additional sub, can’t beat physics, small speakers just don’t play low.

After correct pieces are cut and matched for the sides, it’s time to glue them. Quite easy process if you have press with heat plates. Fortunately our press was just big enough for these tiny speakers.

And here they are, ready for listening.

Not quite sure what to do with the ports, though. Paint them brown, maybe?

Heat blued and stainless amplifier knobs

It’s been a while since I made my last amplifier knobs and it was nice to come back making them. This time I had interesting challenge ahead – I had to heat blue 3 knobs. Material was regular mild steel, which blues to very nice deep black. In the past I’ve had several projects, where bluing worked out fine, but also sometimes it didn’t. Let’s just say the process wasn’t quite worked out yet.

Long story short – I had to reblue these knobs about 10 times, before I got it perfect. Fortunately it seems that I got the process worked out and with next projects I wouldn’t have to mess around so much.

The other lot of knobs was 7 stainless ones, but also with a quirk. The top part of knob had to be concave. Not having CNC lathe and making them by hand was quite an interesting challenge. Fortunately client didn’t need them as 100% identical and slight variation was OK.

The result is here:

Bright cut Zippo engraving

Here’s my latest Zippo engraving done on chrome model. Style is called bright cut, or actually a modified version of it. Surprisingly enough, it was quite easy to cut through the chrome plating and under it was beautiful brass with mirror-finished cuts.

Quick and easy project with rather nice final result.

Signet ring engraving

A project I’ve been wanting to do a long time – to engrave a signet ring. So finally one client came along who wanted exactly that and I was more than happy to do it.

Ring itself is 925 sterling silver one and was very nicely engrave-able. As this was my first such project, it was learn-as-you-go process, and learn I did.

First thing is that the engraving has to be rather deep, so the wax impression has enough contour and relief. Too much fine detail isn’t needed, because it wouldn’t be transferred to wax anyway. Of course the fine detail doesn’t hurt, because then the ring itself looks good.

Here is the final result:

Here are the checks I did during engraving to see what and where needs to be changed on the ring:

All in all a very interesting and educating project.

Two kitchen knives

A project that I’ve been wanting to do for a long-long time – make few kitchen knives for myself. I got really tired of the cheap crap knives that needed to be sharpened every other day and they would still be dull after cutting only sausage and butter.

So I looked up which was best steel locally available and it turned out to be Uddeholm Elmax. High purity powder steel with good wear resistance and other nice properties. I ordered steel at the beginning of 2011, but turned out that factory was going to make thin enough sheets in a few months. So I waited… and waited. Finally received the steel sometime in summer.

Actually I finished the knives quite a while ago and been using them ever since. They are just a joy to use, but as these are my first kitchen knives, they’re not without flaws. Many of them. But it’s a start. I wanted to get practical experience with them, before doing any others. Also it turned out, that I need to make some changes to grinder, because right now I can’t get really good flat grinds.

Anyway, here are the knives:

Knives are 24cm and 13 long, blades are 13cm and 7cm respectively. Handle is of stabilized burl. Blade is heat treated to 60 HRC.

Nude Zippos

Some time ago I was commissioned to engrave 2 nude Zippos. Customer sent me the photos he wanted engraved and I was to translate this to the metal. As I just came back from Italy and saw what was possible, I wanted to see what I could do.

Here they are.

As it has been with all my projects, it’s possible to do better, but it was a really good learning experience.

Visiting Italian Masters, Day 4 and 5

Here’s the last installment on my Italian Engravers tour posts.

Day 4 – Visiting Venice

On Thursday we visited Venice, but as this isn’t engraving related, then I won’t spend too much about on it. The city was nice, glass factory and shops in Murano were just fabulous. I’ve never seen glass art at this level and there I really started to like it. But of course I couldn’t afford 60000 EUR mirror.

Day 5

Final day of my trip and few rather fun things were waiting…

  • Frederique Lepinois
Visiting Frederique was a blast. I hadn’t heard anything about her before, so I was in for a surprise. After seeing few of her works, she became my favorite engraver of the whole trip. She studied engraving in Belgium and its influence was clearly seen on the design.  For my taste this worked very well – kind of symmetrical with very-very nice scenes. Check out the gallery at her own website – Frederique Lepinois.

  • S.I.A.C.E. factory

A family owned gun factory. When Zoli had a nice and big CNC park, S.I.A.C.E was basically all handmade. Some parts were outsourced, but most of the things were made there by few workers. Very cool place. And I got two gun stocks for practicing checkering. What more could I want?

  • Ugo the stocker

Last visit of the trip was stockmaker and his son. They were making some real nice high-end gun stocks and the ones that I saw there were really-really nice.

For the conclusion all I can say, is that this was a really awesome trip. I saw a lot, learned quite a few things and met very passionate, artistic and skilled people. Absolutely worth the while.

After that week in Gardone ValTrompia I spend two more days in Rome and then 2 in Florence. Again, very nice and interesting experience.

 

 

Visiting Italian Masters, Day 3

Third day of the trip was promising to be fun, because I’ve seen the works of 2 studios we were going to visit and like usually with Italians, they were top notch. Pedretti and Torcoli.

  • GS Pedretti

Pedretti is actually also a family business. Gianfranco and Stefano Pedretti – father and son, plus quite a few more engravers at their studio. About a year ago I bought a book about them, so I kind of knew what to expect and was familiar with their style. They are probably most famous for their hunting scenes with very realistic dogs. My guess is, that in their book more than 50% was dedicated to dog engravings. As is the case with majority of Italian engravers, most of the work is done on hunting guns and both Pedrettis are avid hunters, so their hunting scenes are very realistic. They’ve been there and done that, know what hunt is like. So this gives a good opportunity for nice scenes.

Here are 2 works that were in the studio at the time:

  • Zoli factory

Next visit was to a proper gun factory – Zoli. So far I’ve never been to a fun factory before and it was really exciting. I’ve wondered many times how do they do some parts, like barrels. How do they tune, make them precise etc. Find out these things I did.

In Zoli factory a lot of work is done by CNC machines. For example gun frames are first hot-forged to rough size and dimensions and after that CNC takes over. I think there were around 20-30 big CNC mills doing all kinds of different parts. All of the parts are made from one solid piece of steel and nothing is cast, so this gives better reliability and strength to the gun.

Here’s an example of before and after, how one detail is made:

And on to visit out next host

  • Manrico Torcoli

Torcoli is famous because of his fantasy engravings. A style where usually women, animals and plants are kind of fused together, creating beautiful fantasy scenes. Fortunately a lot of his work is done on knives and when the knives are made for US customers, they are more likely to appear on internet. So I knew some of his work.

His workplace was typical for Italians – huge window with a vise in front of it and a bulino tool. That was all, again. His small studio was filled with art and reference books from floor to ceiling. We were fortunate enough to see his knife engraving project in progress:

Here’s a close up shot through his Zeiss loupe.

I did try to take photos of the engravings as close as possible for study material. This one was most successful.

  • Fratelli Dassa studio

Our last visit for the day was Dassa studio. Again family business, but this time they were brothers. They are most known for their enamel work, or color engraving. The results are quite striking and very detailed, unfortunately they didn’t have any works to show in real life, only photos.

After all this fun, we went to have dinner by the lake, where I got to eat the best seafood risotto ever:

Visiting Italian Master engravers, day 2

Second day of out trip was the one I knew to expect the most. Both Gianfranco Pedersoli and Firmo and Francesca Fracassi were known to my by their books I had. Of all the engravings I’ve seen theirs was really the best. Pedersoli was my favorite, because of his style and design. Fracassis were my favorites, because of unbelievably fine bulino scenes. Their working styles are very different, but the class and result is really the best. You can enlarge Fracassis work he’s done on 1×1 cm to 20×20 cm and it still looks amazing with all the detail.

Here we go:

  • Gianfranco Pedersoli
Pedersolis studio was also just a small room filled with books from floor to ceiling and his workplace was near large window. Just like almost all other engravers have.

He is a very lively, friendly and passionate fellow, this shows also in his work. In his own words his engraving technique is very dynamic and he doesn’t have too much rules. Result and speed are important and he’s doing what needs to be done to achieve these. Most of the guns he engraves, take about 300-500 hours, which is indeed fast, considering the quality and detail of the work.

I made 2 small videos during that visit too. I think these show very well his character, style and passion:


  • Firmo and Francesca Fracassi
Firmo and Francesca are father and daughter and since I got a book about them, I’ve wanted to see their work in real life, to really see how it looks and is the detail indeed that amazing as on the photos. That day was the day for these dreams to come true. Yes, their work is totally amazing in real life. Just incredible finesse. Their workplace is also very simple a large window facing north and 2 vises side by side. As they do only the finest bulino work, their only tool seemed to be small push graver. And stone for sharpening it. But I’ll let their work speak for themselves.

Thei said that they work on almost all pieces together, one does one part, the other something else etc.
All in all, that was a very-very interesting visit.

  • Mario Terzi
Final visit of the day was to Mario Terzi. To tell the truth, I didn’t know much about him. I think I’ve maybe seen some of his works somewhere. But as is the case with almost all Italian engravers, it’s very hard to find info and photos of their work from internet.

Of all the engravers we visited during that tour, his workshop was the most unusual. As all the others had large windows and used a lot of natural light, his shop was in a quite dark cellar and used only artificial light. He was a real art fan too, drawing and painting a lot, designing his own yard fences and of course his engravings were quite unique and very interesting. Unfortunately there weren’t any in-progress or finished works there at that day, so I didn’t take any photos. But hopefully soon a book about him will be released, so it would be possible to see his works from there.
