never seen so many over complicated ways to cut a disc from 1mm sheet good job he wasn't asking about making a replica steam engine
maybe you could use the power of the steam engine you make to cut out 3" discsNow, about that steam engine........after dabbling in O gauge fine scale locos I really fancy live steam.....lol
That's no good, you need to mine your ore and turn it into steel first:
To make steel, iron ore is first mined from the ground. It is then smelted in blast furnaces where the impurities are removed and carbon is added.
Iron ore and other iron bearing materials, coke and limestone are charged into the furnace from the top and work their way down, becoming hotter as they sink in the body of the furnace which is called the stack. In the top half of the furnace, gas from burning coke removes a great deal of oxygen from the iron ore. About halfway down, limestone begins to react with impurities in the ore and the coke to form a slag.
Ash from the coke is absorbed by the slag. Some silica in the ore is reduced to silicon and dissolves in the iron as does some carbon in the coke. At the bottom of the furnace where temperatures rise well over 3000 Fahrenheit, molten slag floats on a pool of molten iron which is four or five feet deep. Because the slag floats on top of the iron it is possible to drain it off through a slag notch in the furnace. The molten iron is released from the hearth of the furnace through a tap hole. The tapping of iron and slag is the major factor permitting additional materials to be charged at the furnace top...
yes.....you could do it the easy way .........or you could just buy a metal disc off ebay
But if your going to do a job right.....yes.....you could do it the easy way .........or you could just buy a metal disc off ebay
But if your going to do a job right.....
the hills above teeside have extensive iron ore mines . im sure they will have left a lot still in the groundyou are indeed correct sir where should he start mining ?
Give it some more time, there's more than one way to skin a circle...
You all seem to forget the simpler way of using a 1" 5mm thick washer and hammer peening it out to 3"------ simple
ahh so you never did it right thenHow coincidental is this then, had a call today could I make 12 off 3" x 1.5mm stainless discs to cap some barrier posts off, customer needed them straight away,
45 mins later had these on the bench, no lathes, laser cutters, plasma cutters, flycutters, or holesaws were involved,

Circular jig to hold blank whilst you nibble it round with the guillotine?With this, but for the 1mm ones mentioned in the original post it would be a 1 minute job even with hand snips.

No, thats the hold down foot to keep the material from kicking up as you use it, they were just marked out with dividers and cut to a line, the dot in the middle is deliberate, it will have a stud tacked on to string a chain between the posts, its for a barrier in a packaging factory.Circular jig to hold blank whilst you nibble it round with the guillotine?
