Thank God for...

those

easier

There are numbered (so called "wire size") drill sizes (numbered 80 to

1) and letter (A-Z) drill sizes.

Eg. G = 0.2610"

or 6 = 0.2040"

as well as

7/32" = 0.2187"

AFAIK, the only duplicate is the 1/4" which is fractional and also 'E'

that may be where you were born, but you are clearly a Europeon.

You try to move goalposts almost as much as DimBulb. The resemblance is uncanny.

They why didn't you know what a "fractional read-out" was, liar?

They're about $2 now. No point, though. OTOH, I saw a pair with a 2' span, recently. Might be useful.

Didn't see that. Nest time I'm by I'll pick up a couple. At that price I can scatter them around like I do screwdrivers. ;-)

I'm quite aware of drill size notation. It was just much faster to "mike" them than to try to read each one. ...Jim Thompson

Measure with micrometer, mark with chalk, cut with axe. :)

Or measure with a chainsaw? (Know the tooth spacing?)

Sure we did. The inch is defined as 25.4mm. ;-)

I got one maybe a couple years ago for about $10 from Harbor Freight.

(A "dial caliper", 0 to 6 inches with 1/10 inch per rotation in the dial, nominal resolution to a thou. Accuracy has yet to draw complaints in the

1st inch, little need on my part for thou accuracy over an inch. I just have to remember to press the thumbwheel down hard enough to get movement instead of rubbing.)

Personally, for the few dollars difference, I would avoid the composite ones.

I like to think of myself as a citizen of the world, but my passport still describes me as Australian, and we will be moving back there next year.

Perhaps because they don't sell them in the local super-markets and do- it-yourself stores. I imagine that I could buy one in a Sydney do-it- yourself store - there are still quite a few Australians around who were brought up using inches and feet and know what a sixteenth of an inch is - but I've not had any reason to visit one in recent years. We'll be moving into our apartment in Sydney in June. It has been rented out - unfurnished - for the past few years, so moving in and furnishing the place is probably going to involve a few visits to Sydney do-it-yourself shops.

Yeah, all leftist loons believe they're something "greater" than they are.

Then why did you pretend you knew, when you admit that you didn't? You admit that you are the liar that everyone here knows you are.

Whoopie!

They sell booze in metric, but only because a 750mL is _almost_ a fifth,

1.75L is _almost_ a half-gallon, 375 mL is _almost_ a pint, but they can charge pint, fifth, and half-gallon prices for less booze.

There was a time some years ago when the highway departments went on a metric jag, and you got signs like, "Next exit 3 miles (4.828 KM)"

That was marginally entertaining for awhile.

At the shop where I sit, there's a 6' vernier caliper than can resolve

0.001", but it has to be 72 degrees F in the shop. ;-)

I didn't make any such pretence. My original assumption was that Jim was just using calipers with a digital read-out to make it easier to identify the various drills - which it would. I had no idea that he was brain-damaged enough to need digital translation from from a decimal representation to something explicitly in eighths and sixty- fourths of an inch.

Joel Koltner's reaction made it perfectly clear that fractional read- out covered more than decimal fractions, which was educational. I didn't see any necessity to respond to it - it didn't make any difference to the pont that I'd made

Scarcely. I didn't lie at any point, and your claim that I did is unfounded - which would make you a liar if you weren't notorious for getting confused about what people actually said. It's not as if anybody takes you seriously.

rice I can

Me too. The composite models resolve 10 mils. That's enough for woodworking, but metalworking needs the extra digit-and-a-half.

I've got ten or twelve of the HF stainless steel digital calipers (for butchering into lathe readout devices). I got half a dozen or so on sale for $10 a piece. I've only seen that price once, but they come up for $12-13 several times a year.

After your comments re: your lovely standards I got to wondering. I whipped out a few more of those carbide rods and discovered their length varies. Hmmm. 1.000" was just luck after all.

So I measured 4 rods to 1/10ths with a micrometer, then compared to the HF. This particular HF was dead-on down to the last digit (half a mil, and 0,01mm in metric mode).

If I overpressure the caliper I can rubber the reading 0.000'5 to a mil low, but with ordinary pressure and no special care it's perfect. I'm surprised. Not bad for ten bucks.

I stacked combinations of rods and found the same at 2" and 3"--the caliper agrees with the micrometer down to the last half-a-mil digit.

(I didn't try stacking more than three rods. They start getting wobbly & hard to handle.)

Just out of curiosity -- I'm not trying to slam you here, Bill -- do you plan on seeking employments once you're back in Oz?

I mean, despite all the shenanigans that go on in SED here, it looks to me as though you do have skills that some companies would be willing to pay for...
