Handy

I was in the process of building my forge when I came across this yesterday at the right price. It was working fine but after cleaning it up I am very surprised it worked at all. In side and out it had a oil blend with clay coating 5mm thick. It had to my best guess spent some time in the dam on a farm been pulled out and the clay baked itself for many years. Having said that the coating preserved it beautifuly that most of it had the original paint still on it. Unfortunately I discovered this after a good degreasing and it all came off in the cleaning.

HANDY blower with original stand etc and a plow disc table.

Anyone know anything about the manufacturer?? "HANDY"


For reference you can just make out a patch of the original machinery grey paint, the fn blade was red.

The pipes are 3" Dia.

Some before shots

Nice find. Hit it with a powerbrush and then rub it with plumbago.
Handy to build a forge, ha ha

What the hell is plumbago? What does it do and where do you get it?

RayG will tell us...

Plumbago, as I know it, is graphite mixed with a wax or wax/oil to form a paste that can be painted or rubbed on a surface.

Plumbago or black lead, is graphite in it's original impure form, and was a very common home item to polish the wood fire stove. Steam locomotive and boilers were polished with it. Extensively used by blacksmith, artisan foundry, is available in the UK rather cheap and locally as it is customary, at rip off prices just like in the times of the colony.

I like this old article explaining how to purify plumbago and take out pure graphite for lubrication purposes.

PLUM BAGO. Graphite, or black lead, is an ore obtained from the mines of Keswick and Borradaile, in Cumberland, from Ayr in Scotland and other places. It occurs in beds of various thickness, and constitutes an important article in commerce. The finer kinds are boiled in oil, and afterwards sawn into the required pieces to make pencils. A considerable quantity is used for blacking and polishing the fronts of stoves and numerous other purposes. It has been very common to apply it, in its impure state, to reduce friction in machinery and rubbing surfaces; and, very recently, Mr. Lewis Hebert, of Chelsea, has applied it, in a very refined state, as a substitute for oil, in diminishing the friction of the rubbing parts of clocks. He applied it to a sidereal time-piece, in January, 1816, between which period and 1827 the time-piece was cleaned three times without renovating the plumbago; the friction places being only wiped with a fine muslin rag. In a communication to the Society of Arts, in 1827, eleven years after the plumbago had been applied only once, he states, that the time-piece was going as well as ever. He found a great difficulty in applying it to the jewelled pallats of the escapement, but obviated it by applying it to the friction plane of the teeth of the swing wheel; and he adds, " so ever since the clock has gone without oil."
The process of applying the plumbago is thus:—Take about a quarter of a pound of the purest black lead, the brighter the better; reduce it to a very fine powder in a metal mortar, and, to judge if it is fine enough, take a small pinch of it between your fingers; after rubbing it a few seconds, if it does not feel lumpy or gritty, but smooth and oily, it is good, and beaten enough; have a glassful of filtered water, take some of the powderedplumbago with the clean blade of a knife, spread it on the water, and stir it well; cover the glass, and let it stand for two or three hours; at the top of the water will be a kind of cream, skim it off with a card, and lay it upon a sheet of paper; when dry, put it in a box, to exclude the dust from it; put the sediment aside, repeat the process with some other water and plumbago, until you have acquired a sufficient quantity of fine powder for your purpose; when the whole of the powder is dry, pound it again in the mortar, or bruise it with the bowl of a silver spoon, upon a clean sheet of paper, and repeat the same process two or three times; if the lead is pure, no more sediment will go down; if some does, wash and dry it once or twice more: as soon as no sediment remains, you may be sure that the plumbago dust is pure, and cannot cause any mischief to the pivots and holes; pour some alcohol (the strongest spirits of wine,) into a small glass; having wiped the pivots of the wheels and the holes of the plates very clean, immerse them into the spirits, and immediately into the plumbago powder, they will be covered with it; take a small pencil brush, such as is generally used by miniature painters, dip it into the spirits, and fill the pivot holes with it; introduce some powder into them with your finger, by rubbing the plates over the holes till the powder is even with their surfaces; put in the wheel and make it revolve in the frame for five or six minutes; do the same to every wheel, and also repeat it two or three times; then the holes and pivots will be charged with a thm crust of plumbago, smoother than any polish you can give them; the piece will go twice as long without cleaning as with oil, and truly; if its movement is entirely secluded from dust, there will be no necessity of cleaning it for twelve years, which will be about the time for renovating the plumbago.


If you want to have a laugh, read this. Mind you it is an explanation given by angels ... ha ha

Molecular formula : no
MW : No
CAS No. :7782-42-5

nature : a dark gray with a metallic sheen of Ni Hua material. 3527 ° C melting point. The relative density of 1.9-2.2. Carbon is the same-isomer, with good heat conductivity and, at room temperature chemical lively sexual restrictions small.

Preparation : Graphite mineral raw materials by hydrofluoric acid, hydrochloric acid purification Pure be pure graphite powder. The first purification : raw materials graphite content of about 89%, containing silica, iron and other impurities. The lining of vinyl chloride from the reaction inside the barrel, by adding graphite powder, hydrochloric acid, hydrofluoric acid, steam heated to 120 ° C for several hours after mixing with water washing into centrifuges to neutral. After the purification of graphite with dry air dryer, and then using the almighty fight powder machine broken particles to 325 degrees, then airflow, particle degrees Centigrade 1.5u around. Airflow through the graphite powder accompanied pure pulp mill in vibration vibration within a few days, this graphite materials under different particles in the water velocity different grading. After grade graphite material, after grinding vibration, mixed with more impurities, the need for a second purification, purification method and the first purified the same. After the purification of graphite powder ash not more than 0.5%, according to the corresponding allocation uses stabilizer, the ball mill for grinding mixed, in all types of products. For example, dubbed finishes, powder, liquid, etc..

purposes : water shortages for the refractory metals lubricants, industrial glass coated model agent to increase conductivity and heat insulation material, the electronics industry for the production of screen cover or conductive coating. High temperatures for powder lubricant base material, corrosion resistance weeping slip base material, rubber, plastic filler, carbon membrane preparation Yin and electrohydraulic. Oil for lubricants, heat sealing grease, mold release agents, etc..

The mysteries and the intricacies of the English language ...

Seriously now, I use plumbago to finish forged items that I want to keep rust free with a metallic look.
There are a few ways you can achieve this. One is to simply rub the stuff on steel and repeat this occasionally when rust starts to appear.
Another is to paint the object with a diluted coat of paint (diluted so to have a thin coat that does not mask the details of your work) and when the paint is tacky, just before it dries, you rub plumbago with a rug on the sticky paint. The end result is metalic finish that will not rust.
If you want the object to appear to be rusty, you use a rust color paint. The old anti rust colour works rather well. In this case you rub plumbago sparsely leaving some edges of the paint showing here and there.

The graphite crucibles used in Foundries were made of a material called Plumbago as well.
I do not know if the were just graphite or graphite mixed with clay.
I have seen them but I am not an expert in foundries.
