Sir do you take me for an object of derision or deride my method of mirth? My mirth is Gargantuan! don't you realize that a mirth like mine is both food and water, a monument to me superiority? A great laugh is the banner of a great man, a generous heart, a towering spirit, an expansive soul--such as I unmistakably am, and such as you dare not to dream of being, with your bilious weasel's laugh With your mirth as lacking in all distinction--as lacking, I say, in interest, as lacking in pride, in imagination, in honesty as in lyricism.

:p :p

OK you bunch of scurrilous ninny-hammer flycatchers, the challenge is simple to conduct a flyting contest (a contest of insults, one with a very long cultural tradition) without tripping the forum's word censor or violating the "bad words" rule.

This is a good-natured contest of creativity, extra points for the historically obscure, immediate disqualification if any XXXXX's pop up in your post. Crude vulgarity, the pornographic and common swear words are obviously verbotten. Style, meter, and a rapier wit count.

Lay on you sly knaves :p

seems to be alot of unexpected self employment going around these days

thanks for the link and story
enjoy your new freedom

(even though ever house in my neighborhood has at least one fireplace) apparently even the sight of a woodpiles is offensive to some of my neighbors. I'm a Stealth-Smith! Maybe that's what I'll name the forge. Stealth Smith Forge. What do you think?

Uh Oh

(chalking up more karmic female debt)

in reality this is no different than cooling a computer, a car or a house

1. a heat sink, something that will absorb a large amount of heat quickly and is also relatively immune to the temperature (and corrosion) it needs to withstand. Ideally isolated from your workspace, accessible to clean as needed.

2. a means to transfer that energy to somewhere that benefits you, since liquids have approximately 40 times the density of gases, and water especially has good thermal transfer capabilities while being plentiful and benign, a natural choice.

3. a use, distributed heat is good in winter, good for hot showers year round, good for other hot processes (recuperators, preheaters)
Converting heat to kinetic energy is a bit trickier. Steam, Sterling engines, {so called) Thermal Hydraulic engines, Cogeneration, Trigeneration, combined cycle.

this little downward blip in fuel prices isnt going to last, and few claim to have too much money

start with trying to get her to let you build a forge powered Absorption refrigerator so you can have wild drinking parties in the workshed, then a steam boiler, after you wear her down with those, start getting practical :p

A froe. I still have it hanging on the wall of my shop.

So I need something to help me remove the heat

was my Job Title
13 years as an operations manager for the Great American Beer Festival

course it was just 4 days per year :P

in reality it was simply a three dimensional blueprint to make a slip roller :p

upset the end of square stock
cut down to where its square
drill and tap, insert stud with locktite

insert stud with upset head into the other half of an expansion bolt


alternately weld an upset head to an expansion bolt or lag bolt
drill a hole in the square stock,
plug weld through the stock to the top of the boltlag, then upset (carefully)

we did a lot of masonry mounting

course you can do it the other way round with a stud in the wall and an upset blind "nut" that's been drilled and tapped

errr....

is this for estimating stock needed or precutting?

we used to make quite a bit of chain and rings
not the forge welded ship anchor variety
but serious enough to hold up 9 ft dia chandeliers
a lot of it pre-twisted square stock or octagonal for decoration

then heated and wrapped as a coil around either a pipe or circleoval jig to form a large coil, pounded tight to maintain dimensional similarity

it was then generally cut square right on the jig
an economical approach for both stock and time
of course with that approach there is an unknown amount of stock on the first coil and last coil that will be scrap


point is that there was definitely a +/- attribute that having seen video of Fred Dibnah forge welding ship chain I'd think would also apply unless your individually handcrafting each ring and comparing it to a standard.

A simple jig make a huge difference in time invested

there is a class of gasifiers that rely on a throttle body type constriction to allow the fuel to drop into a lower chamber once its pyrolyzed to charcoal

the trick there of course is a relatively consistent fuel stock
(rice hulls, wood chips, ect) and working out the amount of constriction required

typically the upper chamber is to create woodgas
(mostly CO CH4 H2 and tars )
while the lower chamber is employed to create producer gas with air
(2C + O2 → 2CO)
or in the event steam is injected, water gas
(C + H2O → CO + H2)

rather than a secondary combustion chamber
it could be a chute leading to a quench chamber

You may have seen this

and a large flake of fire scale landed right on the side of my nose

A compressor is an inefficient and costly way to run a forge.

I think some French phrases are not translatable.
My English is approximate.
The site translation, word by word sometimes bizarre texts. :confused:

round here there isnt much choice, you need the concrete to hold up the Radon long enough to evacuate it. (all my work areas are below grade)

thats a cool piece of cast iron there
Welcome to the forums

course its quite alot of thermal mass too

1) Heat an iron red hot
Heat a steel in high temperature and beat it to make up it's shape.

2) Annealing
Inside a forge surrounded by heat insulator, heat this steel to 810 degree and spend 24 hours to cool it. Key point is to spend much time to cool it.

3) Grind
Grind the surface of annealed steel. The color of this steel is black at now, so grind it's surface by using a tool called "TONBOSEN" with much strength.

4) Setting
Fix a steel on a desk, and set it by using a cold chisel.

5) Tempering
Heat a steel inside a hole called "TSUBO". Its diameter is about 10cm and melted lead is inside this hole. Then, take out a steel from TSUBO and sprinkle salt on it, then heat it once more. Enough heated, then take out a steel from TSUBO, and cool it down by soaking into water. Pay attention to a steel not to be warped.

6) Finishing
Check a steel and wash it in acid and do rust-proof, then, it's finished. We make it about 50 in a day.

Pascalou, We call that hoar frost here. Nice pictures

I believe there was a thread on "show us your vice"

In World War II, U.S. factories were cranking out armor, ordnance, and aircraft almost five times faster than the Axis powers. This was largely thanks to private industry's tremendous innovations in the field of mass production.
One area of innovation rose out of the need to cut and join aircraft parts more efficiently. Many factories working on military aircraft adopted a new method of welding that involved the use of an inert gas fed through an electric arc. The breakthrough discovery was that charging the gas with an electric current formed a barrier around the weld, which protected it from oxidation. This new method made for much cleaner lines at the joints and much sturdier construction.
In the early 1960s, engineers made a new discovery. They figured out that they could boost temperatures by speeding up the flow of gas and shrinking the release hole. The new system could reach higher temperatures than any other commercial welder. In fact, at these high temperatures, the tool no longer acted as a welder. Instead, it worked like a saw, cutting through tough metals like a hot knife through butter.
This introduction of the plasma arc revolutionized the speed, accuracy and types of cuts manufacturers could make in all types of metals. In the next section, we'll examine the science behind this system.


''''''''

If you boost a gas to extremely high temperatures, you get plasma. The energy begins to break apart the gas molecules, and the atoms begin to split. Normal atoms are made up of protons and neutrons in the nucleus, surrounded by a cloud of electrons. In plasma, the electrons separate from the nucleus. Once the energy of heat releases the electrons from the atom, the electrons begin to move around quickly. The electrons are negatively charged, and they leave behind their positively charged nuclei. These positively charged nuclei are known as ions.
When the fast-moving electrons collide with other electrons and ions, they release vast amounts of energy. This energy is what gives plasma its unique status and unbelievable cutting power.

A jet of hydrogen is disassociated as it passes through an electric arc. H2 > H + H = 422kJ. The temperature of the arc is in excess of 3700

I read various references to using acid's to remove the flux and vaguely remember something about vinegar.

Is vinegar strong enough to remove the flux residue or is there a commercial product I should be looking for?

It's Vulcan, you need to be facing, and the unicorn horn bowl is realy the key!!
