I am just finishing up my generator and getting ready to start on the servo/slide. I have an old sherline mill laying around and thought I might use it as my...
The drawer slide is what the gear motor will operate...you will probably use the mill slide manually as a means of bringing the drawer slide/servo into range...
Devin, the Sherline has a 20 TPI screw. That will slow it down considerably. A faster motor would be needed. RichD ... From: "Devin Cox" <Holyelvis@...> ...
I tried using a Sherline Z slide for EDM and was not able to get it to work, To much drag, stickson. It may work with a weighted counter balance but I did not...
This is what I was afraid of (the drag thing). I guess , as mentioned earlier, I can just move the slide into place with the z column and have the servo move...
Is the Ben Flemming that wrote the EDM book the same one that wrote the books on building a metal lathe and milling machine? I have both of those books and it...
I have both of those books, the mill and the lathe. I was going to use part of the design of the mill for my mill project. I already have a nice compound table...
The mill book is not in print the Lathe book I have a few copies left but when they are gone I am not going to reprint it. Ben ... From: Chris Reynolds...
Any chance of taking the Mill and Lathe books open sorce for down load in pdf format. I have a MaxNC 10ol mill, a micro mill ( sieg x1 under the harbor freight...
Well, today I have most of the control/power supply done. I'm missing the resistor pack, servo driver IC, IC heatsink, servo. One part ( C6 6.8 uf ), I have a...
Hello, My name is Fabio Gilii, and together with a friend we bougth Ben's book to build one EDM "sinker" device. I am a small toolmaker and have a small...
Those Books were written back in the 80's and I have no electronic copies of it. Ben ... From: kb7cga <kb7cga@...> Date: Friday, November 10, 2006 9:42 pm ...

Good evening, I have built ths EDM machine with what was available in South Africa. It seems not to work so well. Have used a L 293D chip instead of a ...
Good evening, I am not sure why my posed message did not appear but here goes again. I have completed the EDM machine and have some problems. COuld not source...
Good evening. L293 case is DIP16 or powerdip 16+2+2? http://www.st.com/stonline/books/pdf/docs/1328.pdf You can try to command directly L293 to see if motor...
Sakkie, If the Red/Green LEDs flip normally without a motor, I would check your power supply. Can it supply the needed current? That L293D can handle 1.2A with...
Good evening, I have checked when the LED 's go out the output swings in phase from 0V tp 14 V at both te the outputs to the motor. This is even more mind...
Hi, It has been about 20 years since I studied electronics and then it was mostly valve related items. I think I have a Dip 16 meaning normal chip with 16...
Sakkie, please try running the motor directly from the power supply only. This is the part connected to pin 8 of the L293D Measure the voltage as you do so....

Hi Devin, Instead of the Sherline slide as you suggest, I have a Kurt CNC tool presetter without a DRO making it fairly useless as a presetter. However, it...
Hello Jeff, If I could interest you in shipping it to Nebraska, I would be interested in buying it. As it happens, I could use a needs-work presetter. Please...
