Things I wish I had known before learning to ring Cambridge

When I learnt Cambridge (my first surprise method), I learnt it as a line, in detail, which seemed like hard work at the time, and there were some parts of it that I found hard to remember. Now that I’ve been ringing it for a long time, and ringing quite a few more methods, I can see that there is some background information it would have been useful to know, that would have given me more understanding of what I was learning. So I’m writing it down here to help those who are about to learn it, or are in early stages of learning it.

For a piece-by-piece introduction with less general background, see Cambridge Surprise Minor Introduction by Bob Wallis.

Some of what I explain here is meant to help you think in terms of general principles, which I think are easier to remember than row-by-row detail.

The start of this is quite deep in the background to methods, and not that specific to particular methods; the text will work its way towards the specific method quite gradually.

Right-place and wrong-place methods

Unless you have been ringing Stedman, all your hunting so far will probably have been right hunting, which means that when you come down to the lead, you lead at handstroke then backstroke. It’s also possible to wrong hunt, which doesn’t mean it’s incorrect, but that when you come down to the lead, you will lead at backstroke then handstroke. You can do this as a practice exercise by starting plain hunt with the treble staying where it is for one blow, and the second hunting out and the third hunting in. There are two ways of switching between right and wrong hunting (explained below); if these don’t occur anywhere in your method, it is a right-place method. How these work is useful background for method ringing in general.

If you overlay the grid for plain hunt onto a checkerboard, you’ll see that one of the colours of squares is for bells hunting up, and the other for bells hunting down (like the Bishops’ moves in chess). When you turn round at the lead or at the back, you move one square down, instead of diagonally, and that puts you onto the right colour square for your new direction, then you set off in that direction. I’ve put a hatching pattern into the squares to align with the normal direction of movement for that square.

Plain hunt on 6

If, however, you move down one square vertically but don’t change direction, you’ll now be on the wrong colour for the direction you’re going.

Places then continue in original direction

Likewise if you change direction without going down one square vertically.

Change direction without making places

You can see in these diagrams that after these moves, the bell line is now crossing the hatching of the squares, to emphasize that it is going in the wrong direction.

In many methods, including Cambridge, all the hunting is right hunting, and you never make either of the moves that switch you between right and wrong hunting. As you now know there are some things your method’s line will never do, you don’t have to remember whether or not they will happen at any point; they simply never will. This reduces how much you have to remember, which is good. This is also part of why wrong-place methods are generally seen as harder to learn and to ring than right-place ones.

This is background information I would have found particularly useful for learning the frontwork (the start of second place Cambridge, and the end of fifth place Cambridge), where you have a sequence of places and dodges in the same two positions; although it also applies the the backwork and to the Cambridge places in the middle. This is because these rules imply that successive places (with dodges between them) must be in alternating places, not the same one. So when you’ve made seconds near the start of second place bell, then dodge, the next place you make must be a lead, not another seconds.

And likewise if you’re in a long sequence of leads, seconds, and dodges, and you’ve just made seconds, then dodge around for a bit, your next place must be a lead.

If a method were to break this rule, by having two successive places be in the same place, one of those places would have to be wrong, in the sense of backstroke then handstroke, and we know that our method never does that. Knowing this reduces the pieces of information you need to remember row by row, which again is good. For an example with more than just a dodge between successive places, see the second place bell of Bourne Surprise Minor. For an example of a method that breaks this rule, because it’s a wrong-place method, see the 4th and 6th place bells of Beverley Surprise Minor (which is likely to be the first wrong-place surprise method you learn once you’ve learnt Cambridge).

Some right-place building blocks

You can reduce the amount of information you need to describe (and hence to remember) a line by learning some building blocks, and constructing as much of it as you can from them instead of from individual rows. (You presumably already do this by remembering parts of plain bob as hunting rather than a sequence of individual positions; and likewise, treble bob as treble bob instead of as a sequence of “hunt, dodge, hunt, dodge…”.) We can use the constrained set of things you can do in right-place methods to build up a collection of blocks. These things are: hunt, change direction by making a place, dodge. (Dodging does actually put you into wrong hunting for one blow, but that seems to be seen as allowed, perhaps because you couldn’t build so much without it.)

As these blocks use more rows than positions, I’ll draw them across rather than down the page, to reduce the page height they take up.

We can make places twice in succession, changing direction each time as expected for a right-place method. The two changes of direction cancel each other out, and we end up continuing in our previous direction.

Two places

Any sequences that I describe here can be reflected in either axis — you can ring them in either direction (in fact, you usually will ring them in both directions, as most methods are palindromic) and you can also ring them either way up.

Since a dodge, being made of two points which cancel out each other’s change of direction, doesn’t change direction overall (as you will have seen from plain bob and treble bob) we can add it freely into our sequences. Here is a pair of places with a dodge between them.

Places around a dodge

We can also put a dodge at each end of a pair of places. This is called “Yorkshire Places”, as it occurs prominently in the method Yorkshire.

Yorkshire places

Because sequences like this are rung in either direction, it’s helpful to think of the places as far and near places (where far and near are relative to the direction you were going before the Yorkshire places), rather than upper and lower or 3rds and 4ths. So Yorkshire Places are “dodge, far, near, dodge“.

If, however, we only had one place between the dodges, we would have to turn round and go back. You can see this in Cornwall Surprise Major. (This would also occur for any other odd number of places between the dodges. I’m not aware of any examples, but there probably are some.) I don’t think this really has a name; in my head, I call it a turning place, because it makes you turn round.

A dodge each side of a place

Of course, adding another dodge to one end (or both) is also possible, and now we’re getting onto something specifically connected to ringing Cambridge:

Two dodges, a place, and a dodge

This pattern occurs at the end of 2nd place Cambridge, the start of 5th place, and twice (but with the last part replaced by making a place) in 3rds place. In Cambridge, it occurs only at the back, and is described as two and one at the back or one and two at the back.

We can continue to build longer sequences of these; “Cambridge Places” are like two Yorkshire Places joined together by sharing a dodge:

Cambridge places

If you were to add a single place (“turning place” as I call it) to the end of that, and another dodge, you would have to turn back to the side you came from. This occurs in place bells 2, 4, 5, and 7 of Superlative Surprise Major.

Superlative places

That’s not directly relevant to ringing Cambridge (although Superlative shares a lot with Cambridge) but if we cut it down to Yorkshire Places plus a single place and dodge, we get something that does occur in Cambridge, but subtly… I didn’t realise this for decades.

Cambridge frontwork from a bob

This is the second half of Cambridge Frontwork (the start of 2nds place bell) as seen when you run into it from a Bob. So we’ve dealt with the alternation of ringing in first and second place already, because it being a right-place method forces them to alternate; the other problem I had in learning the Cambridge frontwork was where the dodges and places come, but now I’ve realised that the part of the frontwork nearest the lead end is Yorkshire Places, that means I don’t have to remember the detail of where the places and dodges come: “Yorkshire Places, lead and dodge” is less to remember than “dodge, lead, seconds, dodge, lead, dodge”.

Seeing the general pattern

Many minor methods extend to higher numbers (usually only to even numbers; likewise, some doubles methods extend to higher odd numbers), and looking at the higher stages of a method can show patterns that you can’t see at the lowest stage. For example, Cambridge Surprise Minor has one pair of Cambridge Places, one each side of the palindromic place bell, but if you look at higher stages such as Cambridge Surprise Maximus, you’ll see that it is part of a repeating pattern, that you can’t see in Minor because there is only one instance.

Part of the line that I had difficulty remembering at first was at the front of 6th place bell: is it “lead and dodge”, or “dodge and lead”? (And likewise for its mirror image in 4ths place bell.) But when you look at Cambridge Max, you’ll see that the Cambridge Places are always attached to runs of treble bob that go all the way to the front or the back. Therefore, in the “lead / dodge” combination at the front, the dodge is always on the side nearest the Cambridge Places.

And the other side of that is also visible at higher numbers: you can see in Cambridge Max that, apart from the frontwork and the backwork, Cambridge is mostly treble bobbing, except where it’s Cambridge Places or a short run of Plain Hunt (i.e. you miss a couple of dodges). More specifically, whenever you meet the treble when it is dodging, you do so in the middle of Cambridge Places, and whenever you meet the treble when it is hunting between two dodges, you hunt past it. And when you do the latter at the frontmost possible position (as part of 6th place bell), that bit of plain hunt wraps round to include a lead. So that’s another thing that means that in 6th place bell, it is “lead and dodge” rather than “dodge and lead”.

Why I stretched my Land Rover

Someone asked me why I rebuilt my long-wheelbase Land Rover longer than it already was.

I came up with the idea when I was trying to hang on to an academic career. I went back from industry (software) to do a postdoc, then some research assistantships while waiting for a lectureship opportunity, and I was expecting that for a life like that I’d have to move every few years, and wanted to make my vehicle big enough to carry all my stuff. Then the economic crisis came in 2008, and I realized there wasn’t going to be much chance of sticking to that career (as the supply of contracts was clearly drying up), and went back into commercial work.

When I came back into industry at the start of 2011, I was already really keen on the idea of the stretch project, and a couple of years later the chassis got too rusty to get through more MOTs, and so I went ahead with the project, which took about a year of evenings, weekends, and all my holidays for that year.  I had originally been thinking of making it 150″ wheelbase (that is, a 110, which it already was, plus another 40″ for the extra axle) but on the way up to Designachassis to sort out the details I realized that a 170″ would be better (that is, a 130 plus an extra 40) as I already had the idea of fitting an electric motor and batteries for the third axle, and this would allow more room for batteries around the chassis.
The trailer project is mostly for the joy of engineering, though. I bought the trailer body (a 110 hi-cap rear tub, i.e. the type with a tailgate that reaches across the whole width of it) thinking it would be suitable for the pickup extension, but it was too heavy (much heavier than Marmalade’s own rear tub, which I could just about lift by myself) so I decided to keep it and build a trailer using it.
And I like messing with people’s heads, so the trailer’s towing A-frame fits under the pickup extension, and I’ve kept some of the other bits of the tub I made the extension sides from (actually a 109) to make flaps which will cover most of the gap between the trailer tub and the extension, so it will look pretty much like one 9.5metre-ish long vehicle.
I plan to do a lot more camping with it (mostly I’ve just done festivals since the rebuild). One of my present projects is an arduino-controlled manifold to split the hot air four ways from an Eberspacher D7L, the four ways being front, middle and rear of the vehicle, and up to the tent, so I’ll be ready for pretty much all-weather camping.

Building a trailer to accompany my Land Rover

My first idea for building the rear platform was to cut down a hi-cap rear tub, but that turned out to be much heavier than I expected, so I built the platform another way, and kept the rear tub with a view to building a trailer. That’s still in progress, but I thought it was time I caught up on this blog, so here’s the story so far.

The trailer is designed to work with the rear platform, to make almost one articulated vehicle.

The axle is a Range Rover one (happened to be available) and so has hydraulic brakes, which have to be interfaced to the towing hitch which is designed to work with mechanical brakes.

A friend who is a professional welder helped me get started on the trailer chassis, but then got busy with family things, so I did a City and Guilds welding course, and carried on mostly by myself but with some help from another Land Rover friend.

After the main round of work on the chassis was complete (sorry, I forgot to photograph that) we tried putting an axle on and hitching it up to see how it fitted.
Trying the trailer chassis for fit

Then we got it back to my driveway, and lifted the rear tub on, and I started fitting more parts. Here it is hitched to Marmalade again to check I’m fitting everything in the right place.
Putting more of it together, in place for sizing purposes
The brake master cylinder is on one of the cross-pieces of the A-frame, and will be operated by a lever that is pulled forward by a rod from the towing hitch. There’ll be a solenoid connected to the reversing light circuit (via a relay) that blocks the lever when reversing.

Then I fitted a mesh platform like the one in the pickup / platform extension I built for the Land Rover. It’ll have hinged and sprung sides (made from the rest of the 109 body that I used in making the platform) that will join it visually to the platform to give the impression of one long vehicle (just under 10 metres long).
The trailer front platform

The trailer platform has holes for the jockey wheel and the brake master cylinder:

Then the most recent work was to paint the tub:

Adding a rear platform

I’d always liked the idea of a pickup body at the back, but hadn’t wanted to use up the length of the 170 for it, as I also wanted lots of interior space. But the maximum overhang allowed at the back is 60% of the wheelbase (in the case of multiple rear axles, measured from 110mm behind the centrepoint of the axle cluster) so I set out to make a detachable platform with sides and a tailgate, mostly to give me some non-enclosed space off the ground when camping (my friends have started referring to it as the verandah). The platform is supported by the jacking tubes on the rear crossmember, and by what were designed into the roofrack as ladder lugs (the ladder is now at the front, leaving these free).

I’ve done the basic City and Guilds welding course at the local technical college, so got on with completing it without expert help (someone had helped me start this and the trailer project that I’m still working on). I did a test fitting (the project dragged out over more than a year, hence the surface rust) and then sent it off for galvanizing, along with some parts for other projects.

I also build a pair of inverted tripods, to help me fit and remove the platform without assistance. I’m also building a trailer, the A-frame of which will fit under the platform, and I’ll make a slider system so I can move the platform onto the trailer for storage without having to take it apart.

Here’s how I lifted the heavy part, using the tripods and flipping it over.
The platform, upside-down with the mounting tripods
The platform flipped into position
Then I built up the rest of the platform:
The platform built-up

After test-driving it for a while, I took it apart again and sent it, and some other metalwork, off for galvanizing. Here it is freshly back, before priming and painting to match the rest.
A collection of pickled and dipped metalwork.

Then, all re-assembled, here is what it looks like in use for camping:
Marmalade's camping configuration, summer 2019

Since then, I have fitted new reversing lights, and built a tailgate that folds to form a step as it drops down.

My second trip to Albania, and OSCAL

I took a liking to Albania on my first visit, and met up with the local hackerspace, Open Labs, who invited me to come to their annual conference, OSCAL (Open Source Conference Albania). I happily booked transport and hotel for this, including a few days either side of the conference for general holiday and OpenStreetMap mapping.

One of the newer parts of Bari

One of the newer parts of Bari

This time, I decided to take the “scenic route”, and rather than flying directly to Tirana, I booked a flight to Bari (in south-east Italy) and a ferry from Bari to Durrës (the port for Tirana). This turned out not to be a good idea, as there wasn’t enough time for the connection from the flight to the ferry, and I had to find a hotel for the night in Bari and get the next ferry, 24 hours after the one I had planned to get. I posted my progress on Facebook, and it turned out a friend of mine is from Bari, and had local contacts, so he put me in touch with another Emacs user at the Polytechnic, who gave me access to a room with wifi, which was convenient for writing my presentation for the conference.

In the old part of Bari

Having finished that, I walked to the old area of Bari, near the old harbour, and wandered around looking at the buildings and walls, and generally taking my leisure, before walking on to find the ferry terminal. Having got there with about the right amount of time left, I found that it wasn’t where I should be; I had to go somewhere else first, to check in, then come back. Fortunately, there was some informal transport around (an Albanian furgon) and I made it in time. The ship then spent a couple more hours in port for the lorries to finish embarking, which made the previous evening even more annoying retrospectively: in the real physical world, outside the world of bureaucratic ferry officials, there would have been plenty of time to get there from the airport.

I had let my Albanian friends know about the situation, and when the ferry docked, there was a taxi waiting for me to take me straight to the conference, which made somewhat alarming progress, and I got there in time for the start of it after all.

Compared with FOSDEM, OSCAL is tiny, but it’s making a good start, and had an interesting line-up of talks and seminars. It’s not as heavily technical as FOSDEM, with more focus on the user side of software, and on Open Data. I met some interesting people there, and was introduced to some of the local Smart City people, who admitted there was a lot of groundwork to be done in terms of the more basic city facilities.

(Actually, Tirana seems to work pretty well, but it’s not as fussy as some places about things like coning off open manhole covers, so you have to take a little more responsibility for yourself than in England, for example. I don’t have a problem with that myself.) I gave a workshop on editing OpenStreetMap.

After the conference itself, there was of course a dinner and then an afterparty, held in an underground brewpub in Blokku.

After the conference itself, I helped people at OpenLabs learn some more about mapping tools, and we mapped some more of the local area. As well as the main streets, Tirana has a warren of tiny back ways, and an eclectic mixture of modern and traditional buildings.

I had a few days in Tirana after the conference, and explored it some more, and did some more mapping, and ate more ice cream (“akullore” is the first Albanian word that really stuck in my memory). The “brown” flavours (chocolate, caramel, etc) taste good; the fruity-coloured ones taste rather artificial. The Alma was my favourite snack shop, with a range of foods that I wasn’t familiar with but was happy to try.

One day I went to see Bunkart (an Cold War government bunker converted into a museum and an art exhibition). That was quite hard to find, as the entrance has moved but I don’t think all the signs have. I asked a couple of passing locals, who helped me find it in what seems to be a common Albanian way: they walked there with me.

And, of course, I went a few times to the big Mulliri Vjeter café near the hotel. I’m pleased to say that Albania’s own coffee house chains seem to be holding off the big internationals; and deservedly so: they are excellent, with much more character (and better coffee and food).

Like any big city, Tirana has a wide variety of scenes; on my first trip, I was entirely in the centre (apart from a taxi trip out to the cable car) but this time I also went on buses and saw some more of the city.

The restaurant and entertainment complex `Taivani’ is said to be called that because of a fanciful resemblance, although I heard an alternative theory that it’s because it’s next door to the (former) communist party Block.

The national hero Skanderbeg dominates Skanderbeg Square. Some say he should be more than a national hero, but a pan-European one, for holding the Ottomans back for so long.

The uncompleted skyscraper known as the `Green Tower’ looked to be in just the same state as I saw it in last year; I heard the developer ran out of money. That’s not the first time that’s happened here.

As before, I went for some runs in the Grand Park; this time, I could run much further than before (although I’m still doing a mixture of running and walking). If you start from the entrance, and take the right fork, and go all the way to the end and back, you’ll get about 5km in total. There’s no Parkrun here, but it would be an excellent place for one.

The return journey

Go this way

Go this way (from the bus to Kashar)

My return journey had complications of its own. I decided that I’d try Albania’s railway system. The railway station in Tirana was demolished some years ago, with a view to building a replacement sometime; they still haven’t got round to that second stage. So I took a bus to the nearest railway station, at Kashar.

Many trains

The official-looking sign was promising a train in less than an hour, but the piece of paper stuck to the window indicated that the only trains were very early in the morning. Eventually a passer-by explained that the big notice referred only to the high summer season, when many people would go to the beach.


Back to Durrës

Wonderful moist baklava

So I walked back to the main road, and waved down a furgon and was soon in Durrës, where I had by far the best baklava I’ve ever had (it made the baklava we get in England look like digestive biscuits in comparison) and walked along part of the ancient Via Egnatia. I had to wait around quite a bit at the ferry terminal; I think it was worse than going by air, and the ship for this journey was grottier than the one for the outward journey. It was an overnight sailing, but I didn’t get much sleep.
