About Me

I've been taking things to bits, and making things ever since I can remember, starting with dismantling knackered alarm clocks and watches and helping my dad fix the car. Now I have a well-equipped workshop and have aquired lots of new skills, so I can make better stuff. When they first appeared, I became involved with personal computers, and these and developments in electronics have increased the scope of the things that I can do. Just recently retired, so O yes, now I can make all sorts of stuff.....

Ah yes, about those frequent updates....

Oops.  I was supposed to be posting more often this year, and here we are in May with nothing done.  I do have some excuses, though, having spent around 6 weeks on the other side of the globe visiting the gang in Oz, and stopping off at Singapore on the way there and back.

It was great to see the gang again, we went to some amazing places, saw some great stuff, ate and drank all sorts - but most of all, we had some great laughs.  First, a few pictures of Singapore:-

We loved every bit of Singapore, what a shame that its 14 hours away or we'd be back there next week. Its probably the only place I've been in the world where I felt completely safe, day and night.

The electronics bargains that everyone talks about were pretty much non-existent, and although we had been told how expensive it was, I would say it was about on a part with the UK, so not that bad. Although a Tiger beer was around $12/£6 a bottle which seemed a bit steep considering they brew it just around the corner.

Favourites for me? Undoubtedly the Metro, the cleanest and slickest mass transit system in the world. Trains are all bang on time, and stop exactly at the marks on the platform; the track is hidden by walls and sliding doors which keeps noise out and stops that whoosh! of smelly air as the train arrives; most of the trains are driverless, I could bang on and on. The last time I went on the London underground I swear we rode on the same train that I remember going on back in 1966, and as far as I can tell, we were breathing the same air still.

Other goodies:  the hotel (Grand Park City Hall), a four star great hotel for only about £65 a night; the food - every flavour under the sun, and all of it good (though I'm not sure I want to know what some of it was); and best of all, the people - all smiling and polite, a little bow when greeting you, all seemed genuinely pleased that you were there. Even the Thai waitress, who spoke almost no english, when we asked what something on the menu was, she trotted off to the kitchen and took a photo of it and brought it back to show us - we still didn't know what it was, so we ordered it anyway, only to find that it was chock-full of rocket fuel: when she saw that we hadn't eaten it, she offered to make another one without the chillis.
Did I mention that I liked Singapore?

Then on to Oz, with an overnight 8 hour red-eye flight to Sydney, followed by around a three hour road trip to Canberra - with the combination of the travel sick pills and the lack of sleep it was a couple of days before we were functioning properly.

We had been told that Canberra was a boring little town in the middle of nowhere, but how wrong that was.  It sits wrapped around a big lake, and its big, spacious and clean, wide roads, loads of parks and gardens, big shopping centres, you name it. Oh, and Ikea as well.

What did we see? Kangeroos and koalas, of course, plus one solitary snake crossing the road in front of the truck, loads of birds - all more or less different flavours of parrot - and a bunch of lizards, big and small. We met a couple of policemen, who's job it is to fly drones in support of real coppers in dangerous situations - however, they're not allowed to fly at night, or more than 500 feet high, and they can't fly within a few miles of the airport, which effectively means around half of the city is out of bounds. What a great job.


We met a very helpful wine salesman who described one of his products as being 'as dry as an arab's sandal', which I assumed was not a recommendation, and another bloke who talked about someone 'jumping around like a frog in a sock'. Its almost poetic, ain't it?

Sean drove us up a monster mountain in the new Zombie Killer 2, fantastic views from the top - just mountains and forests all the way to the horizon, fantastic. 
Canberra was pretty damn hot, in the 30's most of the time, with the occasional spectacular thunderstorm to clear the air a bit.

To give the gang a break, we zipped up the road to Sydney for a few days. Stopped along the way in a wild west town called Gouldburn where its still 1956, and also on the outskirts of Sydney at a rather nice Japanese garden. Sydney was not as spectacular as I thought it would be - very much like a hot London in many ways, crowded and loads of traffic, not enough parking - but we tramped around Circular Quay, the opera house; the bridge, and along various waterfront places.  Went to Bondi (not too impressed), though Coogee Beach was better and less crowded, and took a drive north of the city up the coast where there are some truly stunning beaches with not a soul to be seen on them. Magic

Then back down the coast to Jervis Bay to meet up with the gang again for a weekend in a very nice shack which was right on the lagoon.  Lots of lazing about; sat on the beach with the whitest sand in the world (some of which we brought back with us in a bag), one of my famous black barbeque servings, and back to Canberra.

Eventually, of course, we had to leave, so off we drive to Sydney airport, pouring rain most of the way, then off on the midday flight back to Singapore. One more full day there, and back on the plane again at the crack of dawn for the 14 hour flight home.


And what has been happening since we got back, I hear you cry? Well a few new things, mostly centred on the making of watches.

I've rather fancied making a watch ever since I discovered that a chap round the corner (known to everyone in the village as 'The Pilot') makes them. A bit of rummaging on the web to find out where I could get the various bits and we were off, and I have to say it was a bit easier than I had expected.

The first prototype ended up a bit small, with a slightly lopsided case.  The movement is a simple Seiko quartz job, the face is painted metallic silver/anthracite, and I made the back to be fixed with tiny screws - this worked well but ended up making the whole watch much thicker than I would like.

Encouraged by this, I set to work on a Mk 2 version.  This one also has a painted dial, but I foolishly chose a Seiko mechanism that has full chronograph capability, including 1/10 second stopwatching. It looks pretty good, but making the small dials and fitting the tiny hands took me around two days, so I don't think we'll be doing another one of those. The whole watch is a bit thinner, in spite of the extra depth required for all the whirly bits, because I threaded the back and screwed it on.  I also cheated a bit and used an off-the-shelf crown because making one of these would probably have sent me bonkers (they have two separate water seals inside a hole that is only 2mm diameter, and a thread that is 0.9mm in diameter).

Can't wait to make another one, but there's a lot of house related stuff to be done first, so watch this space.

Talking to The Pilot also prompted me to have a go at making a small engraving machine for the markings on watch dials - he had made himself a small pantograph to do this, so I thought I could do the same.  Made entirely from bits from my junk box (the main bar is part of an old TV aerial, and the bearings came out of a long line of old photocopiers) it works pretty well.  The dimensions are absolutely critical to ensure that the scaled down image is exactly correct.  I tried to use my little Dremel drill for the cutter, but it was too big and wobbled under its own weight, so I replaced it with the handpiece from my old glass engraver which is rock solid.  I need to experiment with different types of cutter, the best design seems to be with a 30 degree point ground into a pyramid shape, but more testing is needed.  Still not sure if its going to be precise enough for a watch dial, but we'll see.

Before we set off for OZ, I made a determined effort to finish the engine, and actually got it to the point where I could test run it.  It doesn't have any drive belts for the supercharger, so I had to spin that with one electric drill while spinning the crankshaft with the other - it looks mental, but it did actually start and run for a few seconds, wouldn't run very well as I suspect the 'charger was not able to keep up with the demand for air and fuel, but it does run. Check out the sparks and smoke coming out of the exhaust on the vid clip.  Unfortunately, it ain't running no more because my fabricated crankshaft has sheared off at the front, so I have to strip the whole thing down and make a new crank. Not a small task, so it will take some time.



A few other things in progress to report.  One is the installation of a Chromecast Audio widget on the music player in the kitchen, which when driven by Plex on a tablet or phone will play music streamed from my server. It just works, excellent.

I've also started playing with some tiny electronics 'internet of things' modules, more on that later but so far I have a module that can turn on a light by pressing a button on my phone.  I know, that's about as much use as a cheese handbag, but its a start.

More next time!

  1. hello, how are you? This super interesting finish your work with the dial. Please explain how you did it correctly paint the white dial Unpainted the small white dials. the contrast obtained is very good. some protection for small dials used?

  3. Hi Enrique, sorry I only just say your comment. The dial is made from brass, 0.4mm thick, I glued it to the end of a piece of aluminum bar with superglue so that I could hold it for machining. I first skimmed the face in the lathe, and turned the outside diameter, then moved it to the milling machine. I mounted in a 3 jaw chuck on a rotary table with a fixed chisel-shaped cutter in the mill spindle, and 'dragged' the cutter across the dial to make the minute marks. I then moved the centreline of the mill spindle to the centres of each of the small su dials and bored each one exactly 10mm diameter. Put it back into the lathe and polished the dial, then unglued it from the aluminum bar by heating it with a small blowtorch.
    To make each of the small dials, I machined the end of a piece of 10mm diameter aluminum bar, then put it in the milling machine chuck/rotary table and drilled the munute markers with a 1mm diameter drill, then put the bar back in the lathe, polished the end and and parted each one off at 0.3mm thick.
    The brass face was then sprayed with automotive spray paint (several thin coats) before lightly pressing the sub dials into the back of the brass dial. This makes the sub dials sit slightly lower than the main dial.

    I hope this helps? I am experimenting with a couple of new dial designs using water slide transfer paper printed on a laser printer, getting some really good results so far - I'll make a new post shortly about this.

    Thanks for reading!!
