Hi Nicklas: > The thing that worry me most is the fluid, I read it is kerosene,... No worries there. Ace Hardware in the US and other DIY/ hardware stores around the world sell a light oil for kerosine lamps. Kerosine is called Paraffin in the British speaking world. It very much resembles Commonwealth EDM-244 oil, typically sold in 55 gallon drums in the US. The lamp oil is sold in 1 quart and 1 gallon plastic bottles. You'll need a gallon, if only to make sure your erosion zone is 1inch or 25mm or more below the surface of the oil. As long as you do that the hot sparks and vaporized oil have no access to oxygen and there is no risk of fire. Fire= Heat + flammable + oxygen. Take away any one of them and you'll be safe.
I used: Lamplight (brand) Ultra-Pure 99% Pure Liquid Paraffin Candle and Lamp Liquid This product on the Ace Hardware web site looks to be the same but it does not look like a gallon bottle. For $18USD it should be one gallon. http://www.acehardware.com/product/index.jsp?productId=1275451 I bought six gallons pretty cheap because that was a whole case and I paid cash before he ordered it. I think they took 20% off for that. $18.00 for one quart is way too expensive. Your first burn should be with a Poco electrode or copper or brass. Electric motor brushes work poorly-- or so I have read. The others are good. A decent practise burn can be done with 2-5 amps at 40-80 volts. High power is not needed to get started.

Hole adventure but it does not have to be a good EDM machine with todays standard. Then it come to machine dynamics I will however spend more time. As is now motion control work and hopefully there will be most software which is rather small before I could machine my first piece of scrap. The thing that worry me most is the fluid, I read it is kerosene, there are high currents and pumps with not to low pressure so what could possible go wrong?
