There have been several request for a group to support those building the EDM system outlined in my new book, The EDM How-To Book. This is an exciting project...
I would like to thank Ben for showing his EDM at the First CNC Workshop. (Thanks also to Roland for hosting the CNC workshop.) I have been wanting a small...
I know that our group is small right now but just wanted to let everybody know that I just up loaded 11 photos in the photo section. As you guys build your...
Hi Ben, Thanks for starting the group, I'm sure lots of ideas and inspiration will come from it. Are you making progress on the pulse system? I've been...
In your book yoy said that you have parts available to sell, I was wondering what parts you have and the prices. BTW, after reading your book, I am now...
Hi Ben, One thing I am very curious about is the size of the file. I have a Langois type unit and am not happy with the performance. I would never attempt to...
Has anyone actually built this (Garden of EDM) design and got it to work? When I contacted the designer, he indicated that he never completed the project ;...
I will be more of a lurker because I know vey little about EDM and CNC. I just got my CNC home built router going(made from what ever was laiding around for...
... buy the book, and start looking for the parts. I have found that when you know what you need, you find them at work or in a dumpster or whatever. Dave...
Hi Ben, Since I know very little about EDM, I also do not know what to expect for a cutting speed. I hear that it is relatively slow, but I do not know what...
... There was a Radio-Electronics construction article about building such an active load that allowed you to use a 2N3055 as variable power resistor. In...
Hi Ben: I hope it isn't to long before you have PC boards and/or kits available. I would like to get building this. Even if you had the Copper layout ready so...
... Hi Dave, How are you configuring your electrode? Is it graphite or brass? My tap burner uses an electrode from an old carbon-zinc battery. Do you ...
... If you look at the pictures, it is currently a very simple circuit on a perf board. It would be hard to make it difficult, even for a beginner when there...
- Eugene I remember you from the workshop, glad to see you on the group. I am sorry to say that all the parts have been sold. The problem was because I failed...
-Dave Good idea about using a dime for prespective. The face of the electrode used to burn into the file is 1" X 3 1/2" The burn is .062 deep. I did not time...
Hello Ben & Group, I just finished reading the book last week & can't wait to start my EDM. I just have too many little projects to get done first, so it may ...
-Chris I did not have a piece of thin stainless steel but I did have a .005 piece of steel shim stock. I was able to burn a 3/8" hole through it in about 50...
I have been noodling about ways to achieve an EDM design without the significant power loss of resistors (or other dissipative devices such as power...
... I used copper wire and a brass tube (1/8" OD) and connectted the tube to a water resovour. then let gravity do it's work and flush from the inside of the...
... if you charge the cap directly from the power supply, and then open the circuit, then close the pulsing circuit, you drain the power in the cap into the...
Hi Ben, Couple of suggestions. One is to put a link on the home page to your personal site. the other is to put a link on your site to this group. Dave...
Copper is a good electrode and so is brass. I perfer to use a good grade of EDM quality Graphite as suggested in the book. I have used distilled water a few...
Hi Ben, Thank you for doing the test cut on the 0.005" shim stock. Sounds like there is an art to fixturing the thin stock down to a sacrificial piece of metal...
--I am not sure how small is to small I have cut holes as small as .043 with it. Ben - In EDMHomeBuilders@yahoogroups.com, "chrisj_w" <cjwescott@e...> ... the ...
Several people have ask what the speed of burn is of the EDM. I did a test burn this morning using 3/8" diameter piece of EDM-2 Graphite, Kerosene as a...
... I know production EDM's do 10 thou electrodes (0.013"holes) routinely. at some point you cannot make the electrode, or it will be so fragile that any home...
... the test the burn will go faster. The same amount of energy is focused on a much small area. I am sure the .043 hole I mentioned could be punched through...
