lightweight. trying to talk your way out of a mistake by compounding
it, as you just have, is utterly stupid.

i already told you. but you want to prove me wrong, so go get yourself
some hubs, a metallurgical microscope, and do some metallography. post
the pics for us all to see! it'll cost you about $15 for the cheapest
hub, the most likely candidate.

why not use your, er, "ability" to calculate meyer hardness to find out?

unfortunately, you did, yes. "meyer hardness would not change with
indention depth" are your exact words.

so you didn't say "meyer hardness would not change with indention depth"
then? what exactly /did/ you say????

so you didn't say:

"meyer hardness would not change with indention depth" then?

so you didn't say:

"[meyer] hardness does not typically change with indentation depth for a
work hardened material"???

with those statements, what you /really/ said was:

"i am a clueless bullshitting idiot that can't open a book and if i did
open a book, i didn't understand what i read", that's what you /really/
said.

how much surface preparation is necessary for a rockwell hardness test
then tom? have you read that bit yet?

Not reading what people actually write is stupid.

No "jim", you posted the contention, so prove yourself right.

How 'bout these cast bicycle parts, including hubs:

A spoke is too small to test for hardness by Meyer or Brinell methods,
no? Microhardness tests (Knoop or Vickers) are required. Vickers would
likely be the best choice for a small, round section such as a spoke.

Yes, indeed. The indentation depth changes with load (duh), but as the
Meyer hardness calculation includes the load this is taken into account.

Meyer hardness generally changes with indentation depth for a material
that is NOT work hardened, but does not change significantly with
indentation depth for a work hardened material. I though "jim" would
realize this.

Not enough information given to answer the question.

He really should read up on neurotic projection.

jim beam makes progress very, very slowly. When you prove him wrong on
cast hubs, he tries to change the argument to cast handlebars - or
perhaps to the hubs he wants you to buy. Or to the components on your
own personal bikes.

And when he fails in all those arguments, he degenerates into
obscenities.

Makes you wonder what his childhood was like, doesn't it?

I've ridden a cast framed bike. Very stiff it was too.

Dear Clive,

"Introduced about 1893 by the St. Louis Refigerator and Wooden Gutter
Co., St Louis, MO, the Lu-Mi-Num bicycle frame was cast hollow in one
piece (Fig. 7-43). Containing a small percentage of alloy, this
bicycle evidenced a very early use of aluminum. The front fork was
cast solid and all was polished, but not to a mirror finish."

Figure 7-43:
http://i28.tinypic.com/ouxzzo.jpg

"Rights to the manufacture of the Lu-Mi-Num were purchased by M. M.
Cyc1es, Sans Soudures en Lu-Mi-Num who manufactured it in Paris. It
was sold in England by the Lu-Mi-Num Mfg. Co., Ltd. of London."

"Lu-Mi-Num's 1895 ladies' and gents' models weighed 25 lbs. and sold
for $125. At the 1895 Chicago Bicycle Show, a Lu-Mi-Num exhibit
provided for testing the strength of the aluminum handlebar. Two heavy
men were permitted to suspend their weight from either side to show
that it would not bend or break. Samples of the aluminum used in
making the bicyc1e were twisted and bent into every conceivable shape
without fracturing. A gauge demonstrated the perfect alignment of the
Lu-Mi-Num frame, which was c1aimed to be stronger than any steel
frame."

"A chain case, integrally cast with the frame, gave extra strength to
the 1896 model (Fig. 7-44). Today Lu-Mi-Num bicyc1es must be ridden
with care to guard against fracturing due to the age and embrittlement
of the aluminum."

Figure 7-44:
http://i26.tinypic.com/f2u4n7.jpg

--"Collecting & Restoring Antique Bicycles," G. Donald Adams, p. 222-4

Here's a medal commemorating the Luminum cast bicycle:
http://tinyurl.com/6yglcg

The back of the medal modestly reads:

1894

No more steel to rust
No more tubing to bend
No more heavy machines
No more light ones breaking down
No more brazed joints to give out

No more enamel to scratch
No more nickel to tarnish
Many advantages
No disadvantages

If titanium or carbon fiber frames had been available back in 1894,
their drawbacks would doubtless have fit onto the Lu-Mi-Num medal.

Cheers,

Carl Fogel
