Kiwi Dave

A few years ago I worked with an English guy who had migrated to New Zealand many, many years ago. Let’s call him Kiwi Dave.
One day over morning tea, we got talking about “the good old days” and he told me a bit about his early days.
In his words …

It was 1957 when I entered the Shipyard as a young Engineer. Fresh from school, enthusiastic and full of dreams. I would have been at Rolls Royce, but in those days, the apprentice paid the company for the privilege of being taught and that sum of money was way beyond my fathers means. So there I was – In the shipyard – and a few memories immediately come to mind —
I can remember that the Workshop foremen wore a bowler hat, and 3 piece suit to work , complete with fob watch – such was his esteem and authority in the workplace
I can remember fitters and machinists wearing starched collars and ties to work and their labourers cleaning and preparing the jobs for them to work on
I can remember being taught the art of drawing with ink on linen
I can remember spending hours practicing hand printing skills on a drawing board and my printing is still pretty good
I can remember the Chief Draughtsman would come around and measure the thickness of our lines using a feeler gauge. Such was the attention to detail. At the time, I hated him with a vengeance because if it was the wrong thickness – it was erase and start again.
I can remember an enormous machine shop with every machine being driven by belts from a central shaft arrangement. Quite an imposing sight
I can remember that as indentured apprentices, we could never addressed our journeyman by first name – it was always Mr. Or it was the wroth of his tongue followed by a swift clip across the back of the head
Try telling that to the young Engineers today and they would never believe you !!!
Happy days indeed – very character forming

 

 

Damaged FRP (Fibreglass Reinforced Plastic)

Damaged FRP (Fibreglass Reinforced Plastic)

Just under the railway bridge between Rhodes and Meadowbank (Sydney, Australia) there is an area with odd shapes of concrete at strange angles and sort of linked together with sections of GRP.
There are also benches which overlook the water.

I don’t often go there, but a few weeks ago I was in the area and thought that I would sit on one of the benches, look at the river and mull over some issues.

I noticed that there was a hole in the FRP . I have never seen anything like this before and thought it very strange.

Although I’ve used the product on several occasions with great success, I’m not an expert.
I generally regard this product as bullet proof.

Maybe this is a common occurrence – but would be very interested, purely for my own knowledge, to know what has caused the FRP to degrade like this.

You Know That You’re An Old Engineer – Number 8

1. When you can remember that gloves were for wimps – guys on the shop floor had gnarly battered hands.


2. When you can remember that hearing protection was for wimps – which is why all of your buddies now have hearing problems – WHAT DID YOU SAY?
3. When you can remember that the steel plate guillotine operators all had fingers or thumbs missing from their hands – it was part of the job – before guarding and safety came into vogue.
4. When you can remember that bumper bars/fenders on automobiles were practical bump bars, designed to protect the vehicle when it hit a solid object – not like todays excuses – were a slight bump can be a major rebuild of the vehicle.
5. When you can remember tractor feed printers were attached to the computer system and they would churn through mountains of paper for even the most minor data to be printed – if the tractor mechanism didn’t foul up.


6. When you can remember getting lectured on Japanese manufacturing methodology and why they were taking over the world and local industry was closing down – yeah, yeah, yeah – Kan Ban – 5S – JIT – SMED – what is this gobbledygook?
7. When you can remember that companies ran on mainframe computers with slave modules at each desk.
8. When you can remember the 286 computer was state of the art and the experts said they would never replace the mainframe computers. And you still have irreplaceable data on 5 1/4 ” floppy discs – Tho’ you will never be able to read them.  And you can’t remember exactly what it is – but you know that it is very important.


9. When you can remember all welding was stick welding – whats with this tig and mig stuff.


10. When you can remember that steel was cut by hand, with a hacksaw and cleaned up with a file– not an angle grinder.

Is A Better Bicycle Really Worth It ?

Is A Better Bicycle Really Worth It ?

I admit it – I like to ride a bicycle. I think that it’s good exercise and I like to get out into the fresh air. Let me say at this point that I don’t ride on roads with high traffic, as I think that it’s too dangerous. My riding is on dedicated cycleways and paths and its all about “smell the roses” along the way. A nice steady ride. None of the “head down tail up” stuff you see from the hard riding dedicated cyclists.

I recently bought a new bike and this has caused me to ask a few questions and ponder “the meaning of life”.

My old bike was bought back in about 2005 and over the years there have been many parts replaced due to to wear and tear and the occasional spill.
But – just like soft brakes on an automobile can creep up on you, many things had started to creep up on my bike without me paying much attention to them.

Let me also say that I’m not big on bike maintenance – I know that I should be – but I always seem to have too many other, more important things to do – So I adopt the “If it ain’t broke – Don’t try and fix it” approach.
I think that I did clean it once over the 12 years or so – but normally relied on the next shower of rain that I got caught in to wash it down.
After all – Its only a bike and with fairly simple mechanical components – I always gave the chain and sprockets a good dose of lubricant – what could possibly go wrong.
I would have my ride and put the bike in the shed until the next ride. All Good

I won’t bore you with all of the details, but when I finally did give it the attention it needed I was looking at replacing wheel bearings, the sprocket assembly, the chain, various wheel spokes and there was a split in the wheel rim, a buckled wheel etc etc.
Obviously just not worth spending the money to fix it when compared with the cost of a new, similar bike.
So I bought a new bike.

Now – This is where the conundrum starts

With my old bike I was riding about 60 km (38miles) and after the ride there was a fair degree of aching in the legs and I generally would feel fairly whacked. This would carry over into the next day and it was only on the third day that I was back to normal.
Now with my new bike I am riding the same distance, but with none of the aching and feeling whacked afterwards. So – obviously the old bike was in pretty poor shape and fairly inefficient – to say the least.

But I’m not getting the “workout” that I was getting before !!!

• I could try and ride faster and with more intensity – but I ride on a shared path and there is always a steady stream of pedestrians (including children and dogs) and at 67 years of age I really don’t know that I’m capable of pushing the speed.

• I could ride further – i.e. a longer ride, but do I want to commit to more time in the saddle ?

• I could look at making the bike less efficient with maybe a slight steady brake on the wheel – but this is a bit radical and probably an impractical/stupid idea!

• I could try and get in more, maybe shorter rides – but this would not make up for intensity.

I know that some people will say – buy an exercise bike or go to the gym and adjust the resistance but:-

1 – I have tried these exercise bikes and I don’t like them – I like to get out in the fresh air and see things.
2 – I’m lazy – if I’m riding a machine and get tired I will find an excuse to stop and get off – If I’m 30 km from home and get tired theres no couch nearby, it’s grit your teeth and keep going.

Mmmmmm – So it’s back to the Drawing Board

Then again ………

Maybe having an easier ride isn’t such a bad thing after all !!
