I wondered where the odd name "Ashmolean" came from.

Alchemy included the body of practical chemical knowledge. The thousand
+ year old assaying and smelting methods of Theophilius, Biringuccio
and Agricola are still useful. We learned the blowpipe and charcoal
block technique, with which you can literally smelt ores into metals
in your hand.

I used it with a candle to make little animals from splinters of a
broken milk glass light fixture, which turned a spotted brown when
overheated.

The Chrysler 225 slant six? I have one in my garage with less than
3000 miles after a complete rebuild by a mechanical Engineer who
collected Mopar. He said it is from a '63 Valiant. He did a complet
rebuild, then decided to cram a Hemi into the car.

There may be room for a small one wire alternator in there. You
don't need a big generator for the electrical system. Just enough to
charge the battery and to power the ignition system.

Hmm ... I've thought of another possible approach.

Are you familiar with "Geneva gears"? Input is a constant
rotational speed. Output is a precise 1/4 turn (or 1/5th turn or 1/6th
turn depending on the particular gear set involved). There should be no
overshoot on the output of this. Rotate the input gear with a constant
velocity motor, trigger cutoff just a little after the output rotational
position locks, and repeat until out of wire.

Here is an example of a Genevia Gear:

<http://www.tangendrives.com/>

Never dealt with them -- and there are other makers of Genevia
gears, they were just the first web search hit which looked fairly
reasonable.

The Genevia gears even have the advantage that the output
rotation accelerates for about half of its revolution, and decelerates
for the other half.

Enjoy,
DoN.

=========
These work great at low speeds, but have high rotational inertia
due to lots of moving parts. Max rpm is about 300 or so. With a
4 slot cross this would be about 1200 cuts per minute max.

Another thought. Have you thought about buying the wires cut to
length?

I don't know what the hell you're doing here in the first place. You're
nothing but a survival group nut who dropped in here and now you won't
leave. You bitch about this group and the discussions and then you post
off topic and whine about everybody else. Why don't you take your own
advice and go back where you came from because you never will post on
metal content? You said that yourself. You just dropped in to complain?
Like that's a great contribution. Go back and discuss your well stocked
hole in the ground with the other crazies who think the world will end
before you do. In case you didn't notice it you're in the wrong place,
you dropout.

The difference between us is that I happen to know what I am talking
about and you don't. It's as simple as that. You can take any period you
want and try to use it to prove the economy did better under a
republican congress but that claim is really meaningless because you
leave out variables that had far more effect on the economy than simply
which party was in the majority. The fact that you have no depth of
knowledge about the subject is abundantly clear. If you look on google
you will find that there are lots of statistics that show the country
has done better under Democrats. But even that is a stretch for the same
reasons that your assertion failed. Too many things come into play that
determine what the economy does besides which party is in the majority.
If you had any knowledge you would know that. But since you don't it's a
sure thing that you are just shooting your mouth off. Let me make a
guess. You're a conservative, right?

Wow, this is funny! I asked about getting just
casualty insurance on my machines some years ago.
For $25,000 in machine tools, tooling, etc. they
wanted fully as much as the entire house and
contents for all sorts of casualty situations,
including the umbrella policy for persons injured
on my property. Needless to say, I didn't buy
this insurance. So, would having your own web
site on a computer in your home invalidate your
homeowner's insurance?

Totally aside from your success...

Look up "emissivity", and maybe "radiometry". Basically, a material is
as good at emitting photons as it is at absorbing them. Aluminum is
shiny because it's highly reflective, it's reflective because it's
really bad at absorbing photons, which means it's really bad at emitting
them. So when you get it hot the photons don't come out -- in a way,
they 'bounce' off of the surface back into the material instead of
getting radiated.

So when you point the IR temp gun at some aluminum, you're getting a
little signal from the aluminum, and a lot of signal that's just a
reflection of the room around it. Mirror-polish the aluminum, and the
situation gets worse (there's a reason that aluminum is one of the
materials of choice for Really Good Mirrors).

Steel is gray because it absorbs some photons, which means that it's
much better at emitting photons than aluminum, which means that it'll
read better in IR.

Put a dot of black paint on the aluminum and watch your accuracy go up
(unless your IR 'gun' has a built in, unchangeable, and wrong for black
paint emissivity correction factor).
