WD40 works very well and is not expensive.

   In Thailand it is a bit expensive. I've had a few cans where you could only use about half of it.

 

Then no more gas. BTW, what's inside to make it sprayable? ( Without Googling, here seem to be some specialists)

Buy some cheap digital calipers. Useful for measuring many things.

I've borrowed one from a friend today and did my measurements. Holy cow, it seems that they've mixed up the numbers that are printed on them.

 

   They're already in the bin. Thanks for your post!

Sorry, i just cant see it.

One mil (1.00mm) is as good as damn it 40thou (0.040") of an inch.

So 0.10 of a mil is 0.004".

Lets take a look at common valve clearances of say 0.004" IN and 0.008" EX, just as an example.

How can someone with mechanical experience mess up those numbers with the metric equivelants of 0.01 and 0.02mm?

Ya know, just by looking at them, let alone feel (excuse the pun) them, you'd know you are way out mixing the two up.

 

Probably not but could  this be part of the problem?

 

"Mil thickness is a common measurement in manufacturing. A "mil" is a unit of thickness equal to one thousandth of an inch (.001 inch). To convert mil to inches, take mil and divide by 1000. "

The problem was that they printed the wrong numbers on each feelers.

 

 Strange was that I did the same thing five times and I was already thinking of something else causing the noise.

 

    The next day, i did it only once with the right numbers on the feelers and it runs like a Swiss clockwork.

 

Such problems can only happen when you're working and trying to have a conversation with a visitor. 

 

  I should have taken some others and tried it with them. 

 

        I've adjusted the intake to 0.080mm- exhaust to 0.13 mm. 

 

   Yamaha indicates the clearance as follows: 

       Intake .003 - .004 in. (0.070-0.10mm) 
         Exhaust .005 - .006 in. (0.12-0.15mm)

I get mine from a Thai company up in Khampaeng Phet where I get most of the parts to keep my kruangs running. I have always used the whole tin before the internal gas ran out.

 

I pay about 160 thb for a large spray tin.

I bought mine at the local car parts store where even people from other provinces get their parts. 

 

   A big one is around 150 baht, but I prefer the Sonax from Germany. Of course depending on the job I'm doing. 

 

  I also bought my clutch for my Mitsu L 200 2.8 l there and was very positively surprised when they gave me a clutch set made by Schaeffer/Germany for almost nothing. Made in Germany.

Made in China !

This reminds me of the situation where a company ordered a container load of computers from China to a North American country. Upon arrival, they did not work. When reported to China, the answer was, "oh sorry, we try harder next time".

My Father was a machinist. As part of the final test to receive certification they were given a cube of steel. The test was to make said cube 1" - with hand tools.

Them days is long gone tho' ...

 

Actually we were give a piece of round bar and told to make it 1 inch square by about 1 1/2 inch long. Then we were given a piece of bar stock about 3/8? inch thick by 1 1/2 and told to make it 1/4 thk and the 1 inc square to fit through the centre. I forget the tolerance but it had to slip through and had to be the same in any combination of sides when held up to the light. This was to be done with hand tools ie. chisels and files.

 

As we rotated through different "skills, the guys who did turning and milling etc first, would bring theirs, quietly, to the next intake of millers as they knew how easy it was on a milling machine.:whistling: But they still had to be finished by hand. 

 

My first inspection I was told very shiny, draw filing, but deeply scratched! :blush: (by the coarse file used to get it down to size) 

 

Rationale? Our hand tools instructor was ex-Navy and told us that on submarines they only stocked round bar and had to make square parts themselves.  True or not I do not know.

Still bare the scars from that "scam"! we had to file down a 6" block to a perfectly square 2" block, I sneaked onto a milling machine for "help" in my rush, I didn't stop the machine when turning the steel - I managed to cut the end of my right thumb nearly off - my screams and gallons of blood were a dead giveaway, after a hospital visit and a few weeks rest was back at college! ???? 

49 years later I am reminded of this incident whenever I look at my scarred thumb! ????

Er, no.

Never heard nor seen the above in machine shops.

I'm a fitter turner by trade or mechanic-machinist in 'Mercan.

A mil is a mil, ie 1 mm, one millimeter.

A thousandth of an inch , ie 0.001" is a thou.

One inch = 25.4mm.

One millimetre = 0.039 something or other, as near as damnit to 40 thou.

Somewhat confusingly, a mil is also a unit of thickness, equal to a thou, or 1/1000 of an inch.  However, it is used for the thickness of a material, especially plastic sheeting (particularly for plastic bags, showing the load carrying ability of them)...

... and liquid coatings / wet films:

Mils shouldn't be used for measuring gaps or clearances, which is what feeler gauges, marked in mm or in, are for...

… Though, it would appear that our cousins also use it as a unit of sheet metal thickness:

Had to do a similar exercise at college for City and Guilds certificate.

 

We had to make it feeler tight in all 4 planes.

 

Feeler tight being the common phrase for using a .0015” feeler gauge , commonly known as “ a thou and a half “

 

.0001” commonly known as a “ tenth “

 

We had one guy who when asked what was the reading on a tenth clock (DTI ) replied “1 and 5/8ths tenths “ as it was” just over 1 and 1/2 tenths “

 

Logically his nickname became “ 5/8ths tenths “

 

As our business was mainly building machinery under license for an American company the Imperial/Standard system was used, when we broke free from the American license and built our own machines to metric system a lot of us old timers had to convert the smaller metric measurements ( microns ) to thous and tenths before we could visualise the actual measurement.

Lol. I've ordered another one also from China, but this time a better quality, the one my friend had lent me. 

 

  I've also just recently ordered an HDMI to VGA adaptor for only 240 baht.

 

  It takes about three weeks, is usually free, or a few baht shipping, but the next shi_e. 

 

When I connected the cable to my USB, it got so hot that I was afraid that something would soon give up.

 

  Got in touch with the seller who wanted me to write a great review, then he'd refund it!!!

 

 Noe, not with me. Money first, or you'll have a very negative post, plus eBay will be informed.

 

  The same day the money was reimbursed. When it comes to such things, I will now only buy here, for example, at Advice. 

 

You can try it before you pay. And these two parts were not the only things that didn't work.

 

 They sell NGK spark plug copies that might break off and fall into the combustion chamber. That's a total departure for sure.

 

  I'm glad that I've only wasted a lot of time with my faulty liar, the feeler gauge.

 

  The new Superpower has quite a few weak points. 

 

Then when you hear that the Chinese have produced the steel for the Golden Gate, you start to wonder how good that material could be!

I think you mean the newer San Francisco-Oakland Bay Bridge, which has problems.

 

The fabricated steel used in the construction of the Golden Gate Bridge was manufactured by Bethlehem Steel in plants in Trenton, New Jersey and Sparrows Point, Maryland and in plants in three Pennsylvania towns: Bethlehem, Pottstown, and Steelton.   Construction commenced on January 5, 1933 and the Bridge was open to vehicular traffic on May 28, 1937.

My apologies. The steel is for the Oakland Bay bridge in Frisco. The project is part of China’s continual move up the global economic value chain — from cheap toys to Apple iPads to commercial jetliners — as it aims to become the world’s civil engineer.

 

I hope the bridge parts are a bit better than my feeler gauge....????

My two C&G certificates (mechanical engineering) i'm looking at right now whilst typing this.

Funny story.

I left school as quickly as poss, aged 16, proper troublemaker, wanted my own money, lookin' for adventure etc etc.

Anyhow, aged 28 and looking to start my own business up after years of, er, partying and underachieving, i went to tech college.

I was teacher's best boy; long hair, beard, sleeve tats, outlaw biker type, telling all the 16-17 y/o apprentices to shut it 'cos i wanted to learn..........

Funny old world,

Innit.
