Wedding ring engraving

It’s been a while since my last ring engraving, but here is the next one. This time it’s a gold wedding ring made by Ljudmila Funika-Müür.

Ring itself was only 4mm wide, so I couldn’t engrave anything too complicated there. It was also concave D-shaped, so it would’ve been very difficult, or impossible to do a precise pattern transfer to it. I went old school and drew directly with pencil to the metal. It was repeating pattern and didn’t cause too many problems. The white background color is just watercolor, so pencil would stick better and be more visible.

Here’s the final result with background removed and blackened. This photo is much bigger than real life, so mistakes are easily spotted. It actually looks very good.

Engraved watch

It’s been a while since my last “serious” engraving project and I needed something to practice on. Recently I ordered a cheap watch from Mini In The Box specially for this purpose. On the site it was said that the case is made from stainless steel, but unfortunately it isn’t. It is some kind of soft alloy, probably pewter, and very soft. Which also means that it doesn’t take on very fine detail. Fortunately it wasn’t too bad either.

As this wasn’t too serious project and I didn’t want to spend much time on it, I drew the design directly on the watch using China White (fancy name for white watercolor) and 0.3mm pencil. Usually I take the contours for the design and then draw the scrollwork “offline” on the paper. Here are the main backbones drawn.

Looks quite good on the wrist, doesn’t it?

This watch has also quite large sides and bevel. Maybe at some point will engrave these too.

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:

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:

Wax impression close-up. The stars not having sharp and deep edges is because the wax doesn’t transfer all the fine detail in the engraving – it looks fine there.

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.
