Bicycle: The Skill Is Now Complete

01CX

I had done servicing, repairing and modifying bicycle in my younger days but my skill and knowledge was just about that, the common bike that I had so my knowledge was quite limited. I dit it through intuition and by trial and error.

More than a month ago, I bought a new mountain bike and I tried to acquire some used parts for my old neglected mountain bike. I was shocked by the questions they put to me, “How many holes? 32, 36, 7 speed, 8 speed, 9 speed?” And many more. Needless to say when I reached home I started to educate myself through the internet. Thanks to all those gurus on YouTube, I am more wiser now, know some finer points and have the knowledge on how to lace and truing a bicycle wheel. This is the part of the skill that I have yet to experience and manage to do it myself.

The intention to get my long neglected mountain bike rebuild had changed, I decided to build a cyclo-cross instead. Not exactly like it but at least in the intended usage. Only the frame, pedals and the cycle stand of the old mountain bike were used, the rest of the parts were either bought locally or through Ebay. The plan was for a disc brake version and by that I would have to make and weld a rear disc brake mount to the frame. Arc welding was out of the question, local hardware stores did not keep stock on aluminium welding rods because of the price and storage factors. Another consideration was brazing, but low temperature aluminium brazing rod was unavailable locally too. I could get it through Ebay, but the price and postage were not cheap. Apparently I was left with the last choice.

I had done brazing but not gas welding, it was new to me. After some videos on the how tos and safety factors, I was ready for it. I did some dry run on small pieces of aluminium tubes and it seemed to work well. On the other hand, working on a bigger piece was a different matter.  I was reminded about heat loss effect and my lack of experience and skill. It was a struggle. In the end I managed to weld it plus melting some part of the mount and blowing a hole on the tube that I somehow managed to patch it albeit not in a neat way.

The cyclo-cross is now complete. I had learnt how to lace and truing a bicycle wheel and that complete my skill on assembling a bicycle from scratch parts. Also, I gained some knowledge and experience in gas welding aluminium pieces.

So little room for error. My mistake for not checking the width. That's the thinnest I could get for a 27.5

Did a repair, rebuild and rectify on this mountain bike. The suspension design is flawed. The tubes will flex, bottoming the suspension and lock. The pair of levers will prevent this

Birds at Sungai Rambah

When they say you need patience in birds photography, I did not know that it could run for a few days in a row.  I only knew it when I started to present myself at the same spot over and over again for a few days straight.  As I did not use hide nor did I wear camo painted military-like apparel, I must have stuck out like a sore thumb.  They kept their distance away from me and the kingfisher totally out of sight.  Only when I’m starting to become a familiar sight that they started to move nearer and appear.  Lesson learned and I’m starting to enjoy and appreciate the rewards.

Here are a few photos from the recent successive trips to Sungai Rambah at Pontian, Johor.

DIY: Camera Belt Clip

Beltclip

At times I needed to be mobile with two cameras at hand and instant swapping between the two.  Two cameras on a single twin shoulder strap is fine if stationary but not when moving around.  To solve this, I decided to have the primary camera in hand attached to a shoulder strap while the secondary on a clip attached to the belt.  I have read some articles, promotion and advertisements about those clips but decided to build one since I have the components needed.

The components

The components

It consists of a belt, an old Taiwanese made quick release, a camera bag partitioner and a quarter-inch flat head screw with flip handle.  The quarter-inch screw of the quick release only have a slot for tightening it to the camera, I swapped it with the quarter-inch screw with the flip handle.  A hole is punched through the partitioner and the belt, then the original quarter-inch screw of the quick release made to hold the whole components together.

…and the original screw holds the pieces together

I have used it and surely it beats having two cameras on a single twin shoulder strap.  The camera with the primary lens (150-600mm) attached to a single shoulder strap was held in hand and another camera fixed with a secondary lens (24-105mm) was at hip level, and it was a joy to walk around.  I felt that I could even run with less hassle.  Attaching the cameras with zoom lenses will cover a wide range of focal length which is good for covering event besides walking around looking for wildlife and at nature.

Note:  This is a new belt hence this article.  The original clip made with an old worn out belt.  The rest are the same.

Receding Shoreline: What Gives?

Shoreline at Pontian town facing the Straits of Malacca

I had observed receding shorelines in the east and west coasts of peninsula Malaysia.  In the state of Kelantan up north on the east coast, the beach there had been fortified with granites entrenched behind the shoreline to prevent further erosion.  Kelantan is facing an open sea and the constant pounding of the waves is understandable.  Unlike Kelantan, the west coast of the state of Johor is only facing the narrow Straits of Malacca, surely the waves should not be hitting beaches as in the east coast.  Still there are pounding waves said to be caused by passing ships and similar measures taken to tackle the problem.

The thing is that it does not only pertain to peninsula Malaysia, on my recent trip to Lombok, Indonesia, I observed that it too is experiencing receding shoreline.  Nothing to be concerned about because it’s a natural occurrence phenomenon but what set me thinking is the rate. When I was growing up, in a decade I practically did not see any changes, but not now.

Lombok

Lombok lies next to the popular island of Bali.  It belongs to West Nusa Tenggara Province of Indonesia where the capital city Mataram is in the island of Lombok itself and the famous Komodo dragons island just east of the province.

Most of the hotels are located on the west coast and concentrated at Senggigi area, no problem for food and public buses from the airport to Senggigi especially for backpackers.  At Tanjung, further north from Senggigi, there is a recently opened small hotel called Mina Tanjung Hotel.  Nice and quiet, a good place to relax next to the sea but apparently no choice at all for eating out except at the hotel restaurant.  Then there is Kuta, not the one in Bali but a beach in south of Lombok which is said to be pristine and a place for a good quality of surf.  Last but not least, there is Mount Rinjani, fifth highest mountain in all indonesia.

This is my first time in Lombok and I am looking forward to tour part of it tomorrow.

Independence Day Drive

Patriotic display

Patriotic display of Malaysia and the State of Johor flags

31st August is Malaysia independence day and it was last Monday. On late afternoon that day, I decided to go for a drive to Pontian to shoot sunset and some wildlife if possible plus whatever that grabs my attention.  I am trying to familiarise myself looking at the trees to find interesting image for the camera sensor if the forest is not.  A practice session in scrutinising a bland landscape for an exceptional image.

Pontian is the southernmost region of mainland Asia but the honour for the southernmost place belongs to Tanjung Piai (Cape Piai) and it is gazetted as one of the places to go for a tour in Johor.  Not far away across the Tebrau Straits lies Singapore, linked to Peninsula Malaysia by a causeway and a bridge. A quick check on the weather, it was forecasted to be 15% cloudy, but then I forgot to check on one other thing, that is the tide.  Last I saw there were a group of otters swimming upstream into the river when the tide was getting low but on this trip when I reached Sungai Rambah, the tide had totally ebbed and the birds were very few and far away.  That left me with just the landscape and the sunset.  Anyway, I did stop by the pineapple field on the way to the small town of Ayer Baloi and at Sungai Ayer Baloi for some snaps though.

Note:   In this region, you are never short of clouds.  The problem is, there are too many of it. If it is not above, then on the horizon.  Also on a glance, the sky may look clear but there’s probably a thin layer of it.  As a result, it is hard to get dark blue sky even if you use a polarizing filter.  I easily get very dark blue sky in Mecca without using any polarizing filter on a wide-angle lens. (After watching Walter Lewin’s last lecture For the Love of Physics, I guess the particles in the atmosphere here are moist as compared to Arabia causing less blue light reflection.)

My Thought On The New Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary

The old and the new Sigma super telezooms

The old and the new Sigma super telezooms

I should say that on many occasions, I am not patience enough when snapping shots .  This is due to the fact my early experience in photography hinges on covering events, namely weddings.  I try to present a story without much or any manipulation of the subjects unless it is a pose shot.  No problem at all in getting sharp images because the maximum focal length that I use at that time was 135mm for half body and head & shoulders portraits.  Eventually, I learned to shoot quickly and be done with it without the subjects knowing my action in advance.  Now that bird photography is one of my favourite subjects, I have to slow down and not getting too excited because photographing birds require a totally different approach.

The Sigma 150-500mm f/5-6.3 APO DG OS HSM, that’s quite a stretch, is the lens of my choice after some reading and consideration.  It is sharp when I’m relaxed and just trying it out, but on my outings, very few turned up good.  I have to admit that I’m quiet new to bird photography, thus I may still be lacking in techniques and experience.  I have yet to try using hide and/or give tips to the birds, that is food in return for pictures which I am sure that I can get good results but I am not going in that direction at the moment. Hence, I always wonder what could be wrong with my way of shooting or that I am missing something.  I have no other lenses to compare until I got hold of the new Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary.  Just after one initial outing, my heart fills with satisfaction when I review the images on the computer screen.  I now know the reason why and am sure about it.

Being the successor, the Sigma 150-600mm f/5-6.3 has many improvements over its predecessor. On paper, it has focus limiter, more reach, zoom lock, sharper image and programmable via Sigma USB dock, but on trial, well…I like the taste of the pudding. It is faster in focusing and less hunting, quick and snappy stabilisation and a much more silent motor.  Even the lens hood has improved.  It is much more thicker, the locking mechanism is now a ring and the hood attached to it.  This makes the mounting end of the hood stronger and harder to flex.  Many have complained about the thin and flexible hood of the 150-500mm lens detaching, mine decided to jump into the sea while I was in a ferry shooting at the terns following it.

My only critic is that the base of the tripod collar is short, resulting in less grip in holding down the lens with the camera attached and extra care must be given to hold it and not to let it slip while holding.  All said and without doubt, Sigma 150-500mm f/5-6.3 APO DG OS HSM is a good lens but Sigma 150-600mm f/5-6.3 DG OS HSM Contemporary is better. Probably Sigma 150-600mm f/5-6.3 Sport DG OS HSM is the best of them all.

Tip For Long Lasting Tripod & Light Stand

tripod

If your tripod or light stand costs a lot of moolas, you don’t have to worry, it should last.  This tip is for the average tripods and light stands and those below average aka cheap.  It comes from my own experience dealing with both items.

Basically, my principle in buying product is cheap and good, or as others say, best bang for buck.  The important things for me are function, built quality, performance and price.  No point in buying cheap but not good.  Those high-end tripods and light stands, you pay premium for not only the quality but also for the brand name.

Light Stand & Tripod with cracked locking mechanism

The tip is just a fairly simple thing to do, that is, don’t stress it when not in use. So, when in storage or travel, release all the locking mechanisms, free it whenever possible.  The locking mechanisms are probably made of plastic albeit a strong plastic and others may be of metal, usually not of a strong metal as in steel, considering the price paid.  Plastic will increasingly becomes brittle and constant stress on metal will weaken it.  When this happened, it will crack and later on break.  This applies for the clip-locking type only, as for the twist-locking, I don’t have it long enough but still, it can be stressed out and break especially if it is made of plastic. The other problem that I could think about is that the wedge/grip inside the twist-lock mechanism might lose its elastic nature after being held down constantly for a long period of time.  Probably, it is still a good idea not to tighten it so much when not in use. (Note: I saw a newer tripod with a single twist, might also be a good idea too just not to lock it while in storage or travel.)

That’s all about it, let it free, or in the case of the twist-locking type, let it loose.
