Just wanted to comment on the gracious footnote that Steve provides at 14:05 where he states "......so [if] somebody has taught you something in the past, ... I always recommend that you thank them, and continue growing to honor their input into your life". Given all the degenerate crap in the news, Steve's gesture was a humbling gift that made my day......thanks.

The best way to honor you mentors is to pass in what you have learned. I am a tool and diemaker of 40 years and I just really enjoyed your video, and your explanation of the over burn. I was trained in an old edm that yes we used super glue, on the carbon graphite and small c clamps and all kind of stuff, ah the good old days..😃

I'm more of a fan of electrochemical milling: essentially reverse electroplating. Selective masking confines metal removal for etching graphics; a formed cathode can 'plunge-cut', leaving a hole with the same profile as the tool. Wire EDM is more precise, but tool configuration prevents making concavities on flat surfaces. ECM with a shaped cathode works very well for plunge-cuts and concave surfaces, but requires 100's of amps, high-pressure electrolyte pumps, cooling and rigid fixtures... EDM can plunge-cut, but the tool is consumed. I've used ECM and masking to make decorative designs (back-filling etched areas with silver-solder), roughing out the shape of knives (think terraced hill-sides) from steel billets.

Thank you. This is a very clear explanation of how the process works. I did my tool makers apprenticeship at Ronson products in the UK in the 1960,s There was a spark eroder machine that was frequently used to rescue a workpiece that had a broken tap in it. We utilized it a lot 😂

Have always found the process interesting, always wanted to learn more about the sinker process. Worked in a mold shop for only 4 months, and only saw them run the sinkers they had twice the entire time I was there. But they have wire EDM and hole popper EDM where I'm at now.

Wire EDM seems to be more popular in some shops, depending upon the work that comes in. In our latest episode we explain why sometimes it makes sense to burn more of the job than to mill it, in our shop anyway. Our sinkers & wire are always running. It really helps keep the work flowing utilizing another path of getting high end results.

An inexpensive lapel mic will greatly improve the audio. Looking forward to the current and voltage info as well as the lifetime of the graphite electrodes.

Being one of those old timers I'll mention your not quite correct on the square corners knowledge. In your lifetime cnc Mills and lathes do the heavy lifting. It's easier to design around the processes available on the shop floor so square corners are avoided when possible. A shaper can cut square corners and brooches can also cut square corners but usually requires a hole or pocket space for the chip to roll into during the cutting. Not many shops have shapers these days and the skills to run them is even rarer than the machines. A waterjet can also cut square holes. The real advantage to EDM is accuracy. You can maintain far better tolerances than most waterjet machines and you can work in blind holes. A plastic injection piece to hold wires probably doesn't need tight tolerances. The die for this part could have been a dozen different ways using conventional machines and easier to machine tool steels and then had the individual pieces heat treated for the desired hardness. If you got a guy with a burn table in the area that also designs and cuts his own electrodes for the task at hand and at an affordable rate then it makes sense to farm that part of the die build out. With the internet and modern software, and a fast and efficient postal system, farming out work has become the new standard.

Could have better flushing on that first burn. Also we did make a similar clip with that christmas tree type clip. We originally made the die in insert layers, then we developed the first ever rotary electrode system, so we could rotate the electrode through the die insert.
