Bush puncture repair gadgets in Masai Mara

On a recent trip to the worlds greatest natural wonder (well, ok, one of!), the wilderbeeste migration in the Masai Mara, we had the pleasure of discovering an extraordinary bush vehicle repair outfitters in the lovely slum village of Talek, after our extortionately expensive rental car suffered from not one, but three flat tyres.

If you haven’t been to the Mara during the spectacular migration, then you might find it hard to imagine our frustration – try rousing 5 kids and 4 adults at 5 am, pack them and lunch and head off to the Mara River to witness for the first time in our lives, the crossing of thousands of wilderbeeste, zebra, gazelles, lions, – images of crocodiles leaping for the bleating calves … adrenaline racing with anticipation…..and then “poof”, a flat, right at the edge of the Mara reserve.

No big deal right – just change the tyre and continue. Five minutes delay? No, 3 hours later, we’re screaming at the rental agent because the key for the spare tyre’s lock does not work! Aaarrrggghhhh

With second car we head to Talek hardly expecting to find an outfitter who can repair tubeless tyres.

This is what we found.

Finding punctures in a converted wheel barrow - there were 15!

A modified wheel barrow full of silty water and a bit of detergent to find the holes. We stopped counting a 15 – it was very depressing! I don’t even remember going over a thorn bush either!Should have been my first warning – these tyres were seriously worn and thin.

The air compressor system comprised a tank and engine and a compressor unit – the last part was an adaptation from an airconditioning unit off a vehicle! Very creative.

In the end we had to opt for converting a tubeless tyre into a tube tyre – and this is the gizmo that was used to remove the tyre. It was completely home made and very effective. We found an old inner tube with just about the right dimensions at one of the tented camps, 350 shillings and 3 hours later we were on the road again!

Once back on the road Mara never fails to impressWe witnessed the crossing

It was well worth the hell to get to the crossing point – and of course this is where we experienced puncture no. 2! Crazy place for a puncture as you aren’t allowed to step out of your car while animals are crossing. Hours later It was back to Talek jua kali puncture repair for us!

Yeah, the predators were in good form too

After 3 days of stunning experiences we headed back to Nairobi on what may easily be described as the worlds worst road. That was where the new tubed tyre went totally bezerk on us and exploded ripping the tube completely in half! Turns out the tyres were so worn that the wires in the tyre simply ripped the tube open. Nice one!

We discovered that the spare lock could be opened with a good whack! with a tyre spanner and off the lock fell. Away we went.

Words of advice to anyone renting a 4×4 to go on a major trek to Mara or anywhere in Kenya – check everything before you go, take rental company managers personal cell no with and make sure you have credit and full phone charge, take a second car if you can, and a fundi (without my brother I’d probably still be on the road side – thanks a million Dom!). Despite the annoying hassles of the rental car and the unbelievable road, the trip was well worth it. I refused to pay for the lost day and was so glad to see the back of that damn rental car – the agency didn’t quarrel. Gonna buy my own safari car now.

Re-use in the (unofficial) Kenyan Ironworks Industry

Gikomba is a part of Nairobi that is well known for metal working. I had been meaning to come this way for a while, and today afforded me the perfect opportunity to drop down into Gikomba and see what kind of enterprising activities Kenyans were up to.

I ran into a George Odhiambo, a bulk fabricator of everything from wheelbarrows to chisels. The chisels caught my eye, primarily because one of them looked a lot like a shaft straight out of a Land Rover. It turns out that they reuse multiple types of iron for their goods, including leftover pieces from old vehicles. Nothing goes to waste here.

Even more interesting to me (probably because it moved and did stuff with fire), was the bicycle-turned-to-bellows that kept the fire going that would heat the metal rods. It’s a fairly simple, yet ingenious contraption that utilizes old materials with a little bit of engineering. The thing runs all day, every day too, so it’s made to last.

The chisel pictured below is a stone chisel, used in quarrying and squaring stones in the quarry’s dotting the country (most houses in Kenya are stone). They cost about 350/= ($6) to make, and sell for about 650/-= ($11).

AfriGadget: the story behind the stories.

What does it take, out there in the field, to get an AfriGadget story?

Well, this video that I took back in the summer of 2007 shows Hash (aka WhiteAfrican) hard at work getting the Africa’s Modular Machines piece that went up in AfriGadget last November. Yes, the sound quality and camera work are atrocious but sometimes, opportunity just presents itself.

I am happy to report that as you can see, he was busy bringing Firefox to the people as he did this.

The Bamboo Bike project

The Bamboo Bike, an endeavour that aims at building bicycles in a sustainable fashion using bamboo as the primary construction material, is a joint project run by Craig Calfree of Calfree Design, a high tech bicycle design firm based in California and The Earth Institute at Columbia University.

The bicycle is the primary mode of transport in Africa and it is used for everything from personal transportation to moving medicine and the sick to hospital. Sadly, the design used in most of Africa has not changed for the last 40 years to take into account the different ways in which the bicycle is used. In fact, most bikes in use in most of Africa today are based on a colonial British design tailored to individuals travelling short distances on smooth roads.

While making bike frames based on bamboo is not a new idea, most bamboo frame designs simply use bamboo for construction material in a traditional bike frame design. Leveraging the unique properties of bamboo such as its strength and flexibility to meet the specific needs of populations local to various parts of Africa is one of the primary rationale behind the Bamboo Bike project.

The team working on the Bamboo Bike project in the US, Ghana and Kenya among other locations have a interesting blog (last updated in the summer of 2007) that chronicles the struggles of the project team while on site in Africa.

Project gear including Bamboo Bikes and clothing is available on the Bamboo Bike and Calfree Design websites.
