i understood from this is that u are a big ZEROOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO

Ian, thanks for posting the plans, have been looking at the Robert Langois design, nice to have another view on it.

Hi Sanjiv, don't get too frustrated with waiting for someone to make one of these machines, we're all too busy right now on other projects, but in the meantime we're collecting data and designs so that when the desire to actually make one occurs, then all the info' is there.
Nothing is stopping you from having a go.
Remember what Confucius said, "the longest journey starts with asking a few directions from well meaning friends and then goes on to getting some equipment at the local $2 shop and finally when the day arrives and your all fired up and rearing to go, Mum says "go and cut the grass, and then wash the car".

Hi all, I see that deionised water is mentioned for use with EDM set-ups.
I get distilled water from my freezer when I defrost it and end up with two bucket fulls of "snow".
Usually I let the snow melt and bottle it in 'Coke bottles for use in topping up car batteries.
I get the idea that distilled water is preferable to tap water, due to it not conducting or shorting current by electrolysis and so boiling the water away.
This would be the opposite of the method used for producing hydrogen and oxygen in the HYDROX type gas torch where an electrolyte is added to the water to cause a current flow and so breaking the water down into it's constituents parts, E.G. hydrogen and oxygen.

u r right. i had tried a lot to purchase these books from last year. i tried it on every site which are selling these books. but no body is telling that how much i have to pay so that the books reaches to m,e. i m in India (New Delhi)

Can any one mail me plane or any sort of detail to make home made EDM (of course small capacity). I am on the crucial stage and cant offered to buy.

Hi Guys,
I saw a wire EDM running today and it is very impresive.
I don't think an earlier question was answered but cutting 2mm plate it was using 110V and about 0.5amps.
They had the settings on the machine for higher currents.
It was orsm to watch and the 6M of wire reeling itself on one wheel reversing and reeling itself back.
The machine was very solid castings but I think one can be built failry easily.
There is no force on the job. It just has to be held.
It was 4-Axis too. You can make a pyramid from solid steel.
The job was held by 2 rails and water was pumped to either side of the job.
Spraying on the top and bottom.

I'd like to try and build one after the next 2 projects.

Cheers
Rod

Rod, I agree, but i think easy is a relative term. you need very precise motion control and wire handling mechanisms. although there's no force, the the precision demands a rigid structure, ie no vibration. There's a good discussion in here somewhere, worth searching out. Roysol who posts here knows these machines inside and out and has outlined the basic mechanical requirements and challenges faced.

I'm going to build a plunge version first, right after i finish the sheet metal brake, grinder dust extractor, spot welder, one shot oiler for mill and lathe, power supply for the pillar tool, cnc lite mill, circuits and power supplfor for same and a couple of engines...god knows why i just ordered material for a V-8. i better live to 150 or I'll be leaving behind one confusing mess .

Hi McGyver,
Thanks for the info. I'll try and find the the discusion. It's a bit hard with the search engine here as it can't find anything when searching EDM.

I'd like to start on one after the milling conversion, the router, plastic vacuum molder, another milling machine and then a EDM.

To many machines to build, not enough time in the day, money and a nagging missis.

Cheers
Rodney

could you email to me as pdf...vry interested and would appreciate the knowledge!

Having run both sinker and wire EDM's on the job... I can tell you it would NOT be a simple task to build a wire machine of more than 2 axis (basically a wire band saw...)

Sinker machines however can be made rather simple.

I am building Ben Flemmings design currently for my own use. It is about as simple as it gets. Well not as simple as Jon Elson's (the pico-systems link posted earlier), but it is rather self contained if you consider the tank/pump as a seperate unit.

really interested and appreciate if you can email the edm machine building guide as well!
