I watched that the other day, which is what got me interested. Unfortunately he utilized a lot of premade items that are pricy. But I suppose combining info from both this thread and the video, one could make it work. Thanks for bringing it up.Theirs this vid i saw the other day where a guy explains his CNC EDM drill build.

I started working on the ram today.

I made an aluminum block and bored each side for a ball bearing. This will hold the lead screw that moves the electrode up and down. It will mount to the aluminum bar that serves as the ram base.
View attachment 226543The drawer slide has been cut down to length and will also mount on the base bar. It now has 4 inches of travel. You can also see the brass lead screw nut in the photo.
View attachment 226544 I am single point threading the 3/8-24 lead screw in the lathe to get a good fit on the brass nut. It cannot have any backlash.
That is a nice recommendation using this EDM tools into the machine. Thanks for this initiative.I got the fan structure finished and the fan mounted.

The fan essentially will blow through a box to cool the resisters. The fan is 100 CFM. I think it should do the trick. I have designed a bracket to hold the resistors in front of the fan. It will be next on my list.

A friend spent a lot of time making me an aluminum work tank from .085" thick aluminum. It is 18" X 12" X 8"

He cut it, bent it and then tried to weld it on the corners. No matter what we did we could not weld this aluminum. We called the supplier and found it it is not weldable. This aluminum is a cheap grade from china and it will not weld. They said it has to be epoxied, but the epoxy is horrendously expensive. So ...... I am going to pop rivet angles on the corners and seal the inside of the corners wit fiberglass if it will stand up to the dielectric or kerosene.... I think it will, but if anyone knows different, let me know. I hate to waste a nice tank.

Time to start wiring the control.
Продолжение следует ? Какие успехи? Я собираюсь сейчас
