The getaway car

You can learn a lot about my dad's approach to car maintenance from the time it was found the car wouldn't start because the starter motor had fallen off. It was hammered back on with a mallet.

Job done.

Never particularly flush with cash my parents would buy crap cars, to be honest they were probably borderline scrap, and then spend a small fortune adding seat belts - these were 70s cars and they were knackered. I remember a blue Peugeot 504 with an engine so noisy when my dad started filling it with petrol a guy ran across the forecourt shouting "NOoooooooo" because he was convinced it was one of those exotic French diesels.

But the car that looms largest in my childhood memory was a Ford Cortina Mk4. I recall it as being a bright metallic green with a tan interior. KVY 550S was born the same year as me and given my memories I was probably about eight when we got it - I could check... I haven't. Apart from the dutifully installed rear seat belts it was the typical late 70s Ford and on anything other than the perfect day it contributed to the unmistakable suburban sound of engines turning over and failing to start.

We used to call it "the getaway car" on account of the bloody thing never starting.

With me and my brothers in the car, and my parents arguing about whether they'd flooded the engine again, we'd sit in uneasy silence before commencing further attempts in the desperate hope the battery would hold out. We'd threaten the it with the scrap yard and then it would start. A car with proper personality. 

I remember alternators and exhausts being annual consumables. A trip to a tiny auto parts shop that stocked, clearly badly, reconditioned alternators was a delight.... so filled with fascinating oily things. Early on my dad had bought a new exhaust from Charlie Brown's that came with a lifetime warranty. That warranty did for the next few years when, without fail, part of it would drop off.

Once, with everyone strapped in, my mum went to start the car but the key wouldn't fit the ignition barrel... because it was the front door key for the house. Yet she was sure this is what had unlocked the car. Later, for science, I tried a few other implements such as a discarded lolly stick. Yep, that would unlock the drivers door. In fact anything strong enough to turn what Ford referred to as a "lock" would open the door. We didn't bother fixing that.

Eventually rust ate through the scuttle panel and front bulkhead. This was structural and difficult to fix so spelled the end of the car. 

Before the final drive of doom to the scrappy, my dad stuck a for sale sign in the window. A chap came along and offered £150. Not bad... scrap was about £25. Done.

It was a few weeks later we were sat round the dinner table when the doorbell rang. A policeman. "About your car sir, KVY 550S". In the days when the DVLA was notified by the new owner of the car they hadn't bothered which, it turns out, wasn't a great surprise.

The car that would never start had been used, as the getaway car, in an armed robbery in Leeds. 

A week later, the same again. Same officer even.... Our old Cortina had been used for ram raiding in Halifax.

This family car, which can't have been more than 11 years old when terminal rust dealt it a death blow went out in a blaze of criminal glory

I was so proud.

Cars cars cars

Whilst there are too many cars on the UK roads and we all need to drive less, I still bloody love cars. I've never been one for the flashy motor though. The bigger, brasher, noisier, faster.... the less I'm interested in it. 

It's been a lot of years since I really visited this part of my psyche and it's been awoken by EVs. The possibility that I can have a car that's fun to drive, doesn't literally stink and at least has the potential to be propelled by carbon neutral energy is really damn exciting.

I've also been sucked into the world of the CarPervert, Jonny Smith. He's an engaging presenter and I enjoy that he isn't chasing the extreme, outlandish super car nonsense. The man's doing up an Austin Allegro for goodness sake. His love of cars in infectious and really all embracing. He's as interested in the cars of the everyman, the cars with stories behind them, as the engineering marvels that outperform everything else.

All of this has got me reminiscing about the cars I grew up with. The fascinating Volvo Amazon estate owned by the woman at number 10 who never drove it, ever....  but kept it on the road. The VW camper a neighbour had that burnt more oil than petrol - something he seemed to be proud of, but mostly its the cars my parents owned.

I can vaguely remember a few of them. There was a Reliant Robin they had when I was really tiny.... the radio didn't work. A Renault 4 with it's weird gear stick. A Peugeot 504 with deeply questionable brakes and maggots under the rear bench seat because me and my brothers had dropped so much food down there. An awful Talbot Alpine Minx that was just the worst sounding thing every created. A white Cavalier Club special edition thing with a tiny little spoiler. Once, with my grandmother in that car, we were parked at MFI. She piped up that we were parked next to a car that was exactly the same..... It was a 911.

The car I remember most from my childhood was the Cortina. That deserves its own post.

My granddad had better cars. I think there was a Datsun Cherry, definitely a couple of Nissan Sunnys. He bought Japanese cars that worked.

My parents didn't buy Japanese cars that worked, they bought old DAF automatics and had their mechanic friend stick some second hand washing machine belts on when they'd fail.

The first car I drove was a Peugeot 205 1.8 diesel. It was great. Much better than the 1990 Cavalier my parents owned at the time. I once drove that through a puddle and it completely died.

My first car was a 1986 Golf MKII. My dad taught me everything he knew so I chose badly. It was knackered. Something like 60k on the clock and it hadn't been given an oil change in at least half that. But I loved that car and another Golf has always been on my desired list. Never happened because I've always been too practical or poor... my god I really wanted a MK5 when they came out.

Apart from that Golf.... oh and the cut and shut Volvo 340 I replaced it with, my car ownership has been fairly uneventful. They've just all worked. I do find myself craving some originality though. The Citroen Xantia estate I owned was great. Yes the boot leaked so badly the rear foot wells filled with water, and the stupid plastic clutch clip failed and left my wife stranded among rowdy football fans, but it was an interesting car and I loved it.

I'm hopeful the move to EVs will see some interesting cars come back. I may even get one.

NRG

As a bleeding heart lefty-liberal snowflake, how I use energy matters to me. More specifically where the energy I use comes from matters to me.

Like most people in the UK I use electricity from the grid to power things in my home. I have a gas powered combi boiler for the hot water and central heating and I drive a car. We're a two car household by necessity.

Bottom line is I want to reduce my carbon footprint as far as I can (without selling all my possessions and going to live in the woods). I suspect a lot of people thing the same way, so what can we do?

The easy wins are efficiency gains. The loft of our house was insulated, about 30 years ago, with approx 20cm depth of fibreglass. That's better than nothing but not by much, so a small amount of money spent on some nice wool insulation has improved things. Worth noting that although it's more expensive, the wool insulation is nice to handle and means in the future anytime I venture into the loft I'm not left all itchy from disturbing the fibreglass insulation.

Our heating system was also about 30 years old and had started taking a long time to heat the house. A new boiler wasn't so cheap, £2300 to be precise. The replacement uses considerably less gas for the same heat output. Perhaps more importantly it actually works to heat the house quickly. It isn't going to pay for itself and it isn't going to save the environment, but it reduces our gas usage and makes for a warmer home. Thing is, I'm not sure I did the right thing there....

All our lighting was long ago replaced with LEDs. They're just better. It makes absolutely no sense not to do this.

Our car purchasing decisions were influenced by carbon emissions and air quality concerns, so the diesels went and we bought the most efficient petrol cars available to us at the time.

So what next?

Other small changes include making sure the radiator is turned down in our guest bedroom when it isn't in use. I've also installed Hive heating controller - whilst I don't like or recommend Hive, it does mean we can easily turn off the heating if we're out of the house. This is beneficial as our schedule can be unpredictable.

Some years ago we visited Cruachan power station, It's a stunning feat of engineering that can provide a huge amount of electricity to the UK grid, very quickly, on demand through hydro storage. Unleash the water to drive the turbines when you need power, and then pump it back up slowly overnight with surplus electricity. It was a clever way of meeting peak demand without building huge excess capacity. The example given was balancing the grid during the ad breaks in Coronation Street when half the country turned on their kettle at the same time.

It's brilliant, but... turn it on its head. Rather than attempting to have generation meet demand, instead regulate demand to the available generation capacity. It's the principle behind the old Economy 7 system that remotely turned on electric heating at times of lower demand, and charged less for that electricity.

In the past I've always switched to the cheapest energy provider, this time I looked at who I thought was the best and went with Octopus Energy (yes that's my referral link).

Octopus are at the innovative end of domestic smart-grid development and it's really exciting. If you have a compatible smart meter and know what you're doing, for the true nerd they have an agile tariff that tracks the wholesale electricity price and updates what you pay every 30 minutes. It won't surprise you that wholesale prices are high at peak demand and lower at other times. So if you have a load you can shift around such as heating water or charging an electric car, not only can you save money but you can help reduce the load on the grid. Right now I don't have the big load I can shift, but if it cost me much less to move my cooking time back by 40 minutes, I'd be likely to do that.

Another increasingly viable option is battery storage. Tesla were in the headlines a little while ago for their work installing the world's largest on-grid battery in Australia. The headline purpose was to provide power continuity on that part of Australia's grid - which is stretched out pretty thin. Worth noting however is Tesla make money from this by storing electricity when it's cheap, from renewables, and selling it when it's expensive, from fossil fuels.

We all ripped out old hot water tanks in favour of gas combi boilers, but they're going to make a come back. New, highly insulated, mains-pressure hot water tanks will become the standard. Heated by solar where possible and topped up with cheap off-peak electricity.

The next big change we're all going to make is the switch to electric vehicles. Right now they're either too expensive, not available, don't have the necessary range or a combination of these negative attributes but, crucially, they're being built and in increasingly large numbers.

I expect one, if not both of our cars will be fully electric in the next 18 months.

Lots has been said, mostly by those with a finger in the fossil fuels pie, about how electric vehicles will devastate our electricity grid and require new power stations and lots of nuclear and they'll make everything worse. This is designed to spread Fear, Uncertainty and Doubt among the public. It's all about holding back the inevitable.

Here's what's going to happen.

Everything will become electric. To heat our homes we'll eventually move from gas to heat-pump systems, though this will take a long time. Faster will be the return of the hot water tank, heated with off-peak electricity from the grid, or solar from your own roof.

Every daily driver vehicle will be electric, and these batteries can also provide buffer to the grid.

Those with room will install domestic battery systems to make the most of their roof solar.

Energy companies (Tesla has just applied to become a UK energy supplier) will build grid battery systems.

All this electricity will come from renewables.... eventually I really do think all of it will. Every last bit. We'll have enough generation capacity between solar and wind coupled with enough storage to make that work through the night and on the quiet days.

It's going to take time to get there, but I rather suspect it's going to happen quicker than most of us suspect.

Meanwhile I try to use as little energy as I can. I turn the heating down, I insulate (myself and my home), I don't drive unless it's necessary and I use an energy supplier that invests in renewables and at least lets me offset my gas use.

Brexit day reflections

I can't think of anything recently discussed in the UK that has raised quite as much ire as brexit. Well now we've "got it done", in that the relatively easy part of officially leaving the EU has now happened, there only remains the really difficult part of diplomacy, compromise and negotiation to sort out all those trivial matters of how we, as a nation, go about pretty much everything in this connected world.

As a stupid, lefty, remoaner, as opposed to being a wise, lefty, brexiter (like my parents) this is a sad day. I see no gain, only loss. 

It's going to take the rest of this year to understand what this really means for how we interact with EU countries, what it means for business, how the border between the UK and Ireland is going to work.... All the big uncertainties of the past few years remain just as uncertain today.

Given some of the people involved in our government I can't say I trust them to do anything well. Offered the choice between retaining alignment with the EU and throwing away decades of sensible policy for the sake of jingoistic soundbites I have my suspicion which way they'll go. We'll see.

For me it feels like the UK is like an amazing guitarist who, believing they're being held back by the rest, quits the band and goes out on their own only to realise, too late, that actually not many people want to hear 38 minute solos. Meanwhile someone else has stepped up in the band and they're actually doing quite well without us.

My prediction (I'm almost always wrong) is for us to re-join the EU some years down the line with a much smaller role. We'll probably have to be guitar tech, or coil the cables.... or something.

Toyota Yaris hybrid

These cars have their detractors but I really rather like it. Almost every criticism I've heard, suggesting the car lacks excitement, individuality and dynamism, is exactly what makes it ideal.

I am going to drive this car relatively slowly on congested roads most of the time. Even out of town it's rare for my average speed to make it over 50mph. You can take your sharp, dynamic handling of the Seat Ibiza and shove it, because it's meaningless in a straight line under 30 as you're queuing round Leeds.

Last year we bought a Skoda Fabia, and it's a great car. Surprisingly large in estate form, with the 110bhp one litre, three pot turbocharged petrol engine that's surprisingly quick when you need it to be and impressively frugal the rest of the time.

The Yaris is an interesting comparison because on paper it isn't much slower, but it certainly feels it. I suspect a lot of that is perception. The lack of gear shifts from Toyota's hybrid system seems to upset my perception of speed, but honestly I don't know who I'm trying to kid, the Yaris is slow.

Where it beats the Skoda is in refinement. The Yaris is smoother, quieter, feels more assured on bad road surfaces and feels like it's a bigger car (it isn't).

Hybrid Synergy Drive takes a little bit of getting used to. When one's entire driving experience has included selecting the appropriate gear, and engine revs being a key part of driving, it's initially unsettling to have a drive system where engine speed isn't necessarily linked to the road speed.

There are a lots of videos explaining how Toyota's system works and it's clever stuff but perhaps the best thing about it is you don't need to understand any of this, because once the transmission is in D you drive the car. However, understand how it actually works and this helps you get the most out of the car.

By most, I mean MPG because nobody buys one of these for the performance. You've bought one of these because you want cheaper motoring (which this doesn't really give you) or you're concerned about emissions and want them as low as possible, which is my motivation.

So far, with a mix of slow town traffic and longer distances, the trip computer reports an average of 59mpg which isn't too shabby. It's better than the Fabia, which is otherwise one of the most fuel efficient cars I can find. That's also in winter, where the engine will use that bit more fuel while it gets up to temperature.

So the Yaris is comfortable, easy to drive, reasonably frugal, feels well made and has the legendary Toyota reliability but there has to be a down side and I have four significant frustrations:

  1. No Carplay. This may seem trivial but we have it in the Skoda and it's brilliant. My Yaris has satnav on the clunky, sluggish infotainment system. It'll do but it's already hopelessly dated and that's exactly the problem Carplay solves.
  2. Battery capacity. Toyota have to strike a balance between battery cost, weight, capacity and the available charging power. I suspect they've arrived at the best compromise but I still find myself wishing they hadn't used the batteries from a 1980s camcorder and the electric only range was greater. Two or three miles would be ideal. Instead it's typically less than a mile so a congested urban drive will see the engine running to top up the battery.
  3. Performance. Again this is all a massive compromise but I have had a couple of occasions when I wish this efficiency focused car could give me a bit more poke.
  4. Economy. This is probably the biggest and goes with the previous two. I don't think the engine is very good. Toyota have used their Atkinson cycle engine design that's all about efficiency over power output, but the VW engine in my Skoda is smaller, more powerful and I reckon  if you coupled that with the hybrid drive would be even more frugal. I'm a slow driver and have been very gentle with the Yaris yet I don't get close to the claimed economy figures. Yes it's better than the Skoda but perhaps not quite good enough after all the compromises. Let's see what warmer summer mornings bring.
Despite the misgivings overall I think Toyota have done a good job with this hybrid and I'd certainly recommend it to anyone who spends a lot of time in traffic. For me, the bottom line is this car can never truly satisfy because it isn't the EV I want, but can't afford.

Outside the church

It's been a few years since I left the employment of a church in circumstances that were undesirable. What I perceived as dishonesty and indifference shocked me and left me questioning assumptions I had made about the approach of people I worked with, shared bread and wine with and I thought loved and respected me.
A significant side effect of this was I could no longer gloss over aspects of that church's theology and assumed belief that I realised I simply didn't believe. Truth is I hadn't been aligned with the conservative evangelical thinking that pervaded the church for a long time, if ever.
Despite initial attempts to stay part of that church family it became clear I needed some space and time to grieve the loss of a community that never really existed, but I thought did... and frankly to get over the anger over how I and others were treated.
Getting a new job, stepping away from the church and taking a few years to slowly reflect on my faith has been difficult, often painful and a huge part of me would much have preferred everything just to stay as it was, but life moves on and so must I.
I went to work for a University and the first thing I noticed, looking back, was how small the church was. When I was in there, part of the staff team, "serving God's transformation of the north" it felt like I, like we were part of something. I really did start to believe we were within a subversive movement and that one day revival would come, with supernatural force, and our society would be transformed for the better. It felt like we were part of something big.
Truth is the church is small and getting smaller. That particular church has seen people leave faster than new people have joined, and the wider evangelical movement in the UK increasingly looks like a fringe group of crackpot fundamentalists in our increasingly secular society.
I also felt less stress... eventually. I moved to a new job with a steep learning curve and brought my good protestant work ethic and desire to do well, so pushed myself, yet this was far less stressful than the role I left behind.
I've subsequently spent a lot of time reading, thinking, listening to podcasts that challenge and inspire me, all in the name of trying to understand what I actually believe.
Some people are, by nature, very black and white about things. There's right and wrong, good and bad and nice roles into which people can be slotted. I think I've long been able to see the grey inbetween, even if I didn't always understand it, though I've found age brings a greater appreciation of how rarely the nice simple categories work.
Mostly I've concerned myself with Jesus.
Christianity is supposed to be centred around Jesus but interestingly not very much of the behaviour I've seen from Christians over the years (and I include myself in that) seems to reflect much of what Jesus actually taught.
Part of the problem is many, probably most people in churches don't have the first clue what Jesus’ teaching means. They don't understand his words and actions within the context of him living as a Jew under Roman occupation. The way in which the Bible is read and understood is so devoid of colour and life as to make it almost meaningless and it's often taken as as either a set of literal instructions or a historical document... of course it's neither.
At some indeterminate point I’ll probably take a subject and try to explain what I believe about it, at the time of writing, and why I think it's important to consider alternatives to the widely received churchy approach. I am probably wrong about everything, I am no scholar or theologian and I have not extensively studied the Greek... these will be personal musings. I'd love to hear your comments.

Juin Tech R1 brakes

Back end of last year I got a new bike on the cycle to work scheme. A local bike shop had last season’s Genesis Day One 20 available for a good price. It fitted the bill with disk brakes, mud guards fitted and the hub gears I wanted so I bought it.

Having lived with this bike for a while here are my musings. It’s pleasant to ride. Comfortable, stable at speed and generally mostly what I’d hoped for from a fast commuter bike.

There are downsides though, the paint finish isn’t good enough; it’s very easily scratched and seems really thin. A gentle altercation with a colleagues machine in the bike shed has left me with a surprising amount of bare metal showing, which will rust quickly left alone as the bike frame is steel. Of greater concern are suspect pin holes visible near some of the welds. I suspect this bike will rust badly, which makes me sad and more than a little disappointed.

Probably the biggest issue I have with the Genesis is the choice of components. Some are just not good enough. This isn’t a very expensive bike, but it isn’t cheap either and I’d expect things to work properly. The gear shifter is apparently known to cause problems, though mine has been fine so far. But the brakes are really the big issue.

The fitted promax dsk-717 is a cable operated mechanical disc brake and imho it’s terrible. In fact the brakes setup on my bike has been so bad I’d say it was dangerous. This is the first bike I’ve owned with disc brakes and I expected good things. I’ve previously had rim brakes and I have a beaten old carrera subway 8 with Shimano roller brakes. These should be out performed by the more modern disc brakes, but they weren’t,

The comparison with roller brakes was particularly interesting because these are not well regarded for their stopping power. I actually quite like them because whilst they may not be the most powerful brakes, they are consistent in all weathers, which is worth a lot on a commuter bike.

Anyway, I set off with my shiny new bike and was immediately disappointed by the brakes. I expected improvement with bedding in but it never came. Eventually I realised the rear was particularly bad and I wasn’t safe indicating right with traffic around. Something had to be done.

Adjustments checked I couldn’t find a way to lock up the rear wheel at any speed other than a crawl. Not good. So new pads, following a clean of the rotors with isopropyl alcohol in case of oil contamination. It was better but not good.

Because mechanical calipers only have one piston, the arrangement requires one pad to be as close as possible to the rotor, which means there’s always a small element of flexing the disc to squeeze it between the pads. Get this out of adjustment due to poor installation or worn pads and it dramatically affects the braking effort.

Despite clean rotors, new pads and numerous attempts at setting things up I couldn’t get satisfactory performance so I opted to replace them with the Juin Tech R1.

The R1 isn’t cheap at £151 delivered (they come as a pair), that’s a hefty price tag for some bike bits... for me at least, but brakes are something I don’t like to skimp on. There are Shimano hydraulics available for sensible money unless you have drop bars when they suddenly get very expensive. I also quite liked the idea of just replacing the calipers, rather than having to re-tape the bars of my not very old bike.

The Juin Tech R1 is a hybrid hydraulic brake. It’s cable operated, so works with my existing levers, but is internally hydraulic. The most obvious advantage is both pads move against the disc which means you avoid the regular fine adjustment of having a pad almost dragging all the time. There’s no wasted effort of flexing the rotor, just two brake pads neatly clamping the disc.

Because I’m fabulously lazy, and for a couple of other reasons I opted not to change the rotors, just giving them a clean once more. The mountings from the promax lined up nicely so actually installing the R1s was just a matter of swapping them over and took me no more than 15 minutes.

The difference is like night and day. Suddenly I get the disc brake experience I was expecting. The Juin Tech R1 has a nice feel with good modulation and significant stopping power when required. I’ve yet to test them thoroughly but I immediately felt far more confident for my 8 mile ride home.

I suspect I could probably have got decent performance from a different mechanical brake (surely they’re not all useless), but I like a gadget and had heard good things about these and similar hybrid designs. As a very simple swap out I’m delighted with the performance. My only frustration is Genesis fitted such terrible brakes to begin with.

Which reminds me, there’s one other disappointment with the Genesis, the CST tyres.... terrible. Got a puncture at both ends of the bike. So they were replaced with Schwalbe Marathon Plus for a drama free commute. Perhaps what this says is, as I suspected a while ago, I should have spent more money on the bike in the first plce. Still, making these gradual improvements is actually quite fun.
