fuel system woes

[rogerthebodger]

As far as I can make out from a few minutes googling, from a metallurgical point of view, brass is an alloy of copper & zinc, with or without other metals, such as lead and antimony in DZR brass. Bronze is an alloy of copper and tin, with or without additions, but with no zinc, so the "bronze" my prop is made of is actually a brass. What makes an alloy brass rather than bronze seems to be the presence of zinc. Take a bronze and add more than a trace of zinc and you've got a brass.

Absolutely correct. The problem is that Paul cannot seem to accept when he is wrong and when challenged cannot refute the facts.

I really don't know what h means by "proper brass" Does he suggest DZB is not proper brass as it has other elements. Does Paul suggest that DZN should be called Bronze as it contains other elements.

Spot on. Some people have difficulty accepting that though, but it matters not. The great thing about science is it is not a religion. Unlike religions, it works just fine whether you believe in it or not.

Any one who has a tertiary qualification in Engineering (at least B Sc Engineering) of ( C Eng)

I have a B Sc in Mech Eng and until I could not afford the fees in 1988 I was MIMechE (C Eng)




Correct, they are what are called ere artisans. Their skills are more practical than most Engineers but are still very skilled but in a very different to qualified Engineers. Some of us have done and 5 year apprenticeship than included practical skills to help design Engineers to design mechanical components that can be made economical



The proper guys who would know is any one with a degree in Metallurgy which is a domain and study of materials science and engineering. Vyv Cox is a very own Metallurgical Engineer.



No terms like "Engineer: is used by people who need to bolster their ego and to con people they know more than they do to people who just don't understand the difference.

Can you translate please “Some of us have done and 5 year apprenticeship than included practical skills to help design Engineers to design mechanical components that can be made economical”
Plus you are being very patronising with your description of “tradesmen” I sometimes called myself a Maintenance Engineer. I knew more about engineering than some of the wet behind the ears grads we were foisted off with in Africa. They used to come to me for advice!

Like religions, you're going to get hung out to dry, more or less literally depending on the century you live in*, if you argue with the high priests...



* centuries can vary by geography, not just Anno Domini

To me Artisans have a high level of skill in manufacturing mechanical components.

I agree that some as you say some of the wet behind the ears grads lack real life experience.

It a combination of a tertiary qualification, Apprenticeship and post qualification experience that makes a proper Engineer.

A medical doctor goes through similar stages of training before become registered by the medical council.

Chartered accountants have similar stage of training to become chartered.

Lawyers also have a similar training before being accepted by the law society.

So you have people who call themselves as "engineers" and those who are Chartered Engineers.

Would you wish a steel fabricator design a suspension bridge or would you prefer a Charted Structural Engineer.

The knowledge of both are different but are as important as each other with different level of skills and knowledge.

In my Mechanical Engineering Degree I had to study, Strength of materials, Structural design, Thermodynamics. Fluid Dynamics.Design of mechanisms, as well as Chemistry, Physics and Metallurgy to a background level so I can appreciate the subject.

I also did Production Engineering, Industrial relations and Factory management again to a limited degree.

“tradesmen” and Artisans study their subject and develop their skills to a much higher level than even Chartered Engineers.

Can I just say that I too had fuel problems. I replaced the two filter heads with screw on ones but still the same problem (though CAV one may have also been extenuating things). Replaced hose and still a problem. Finally replaced fuel bulb I had looked at and considered to be in fine fettle. Fuel problem resolved. In future I will replace the bulb every couple of years.

I hold no views on brass or alternatives.

There are also different branches of engineering. I am a chartered civil engineer with a bachelor of engineering, B.Eng, in civil and structural engineering. Metallurgy was not on the curriculum and neither was electronics so I have no knowledge of either. There's long been confusion over who is entitled to call themselves an Engineer and the term is often applied to anyone with a spanner and screwdriver and knows how to use them but not necessarily why.

To be honest, I'm not really interested whether people are called Engineers, Technicians, Mechanics, Fitters etc. and I've used all these terms to describe myself as the fancy takes me. All I'm interested in is can they do a good job.

I accept what you say but how can you tell if the person you do a good job.

Ghostymoron being a Chartered Civil Engineer can be held personally accountable for his work in civil engineering be any structure or building fell down and killed someone.

We have seen several structures in the third world fall down and kill people someone should be held accountable and charger with culpable homicide.

The same goes when a boat looses its keel and people are killed.
