I made a set of these today using scrap oak and .9999 silver wire. They came out really nice ( way better than they look in the pictures) but I havn't had a chance to hear them yet. It took about 20 mins to make the two of them. I will do them over again real pretty now that I see they work.

You should probably call those "DIY 47 Labs" rather than "DIY Eichmans", because the Eichmans themselves appear to be knockoffs of the 47 Labs Otakit RCA cables.

What a great idea! I've been using the originals (copper) for a while and really like them a lot but there is no reason yours wouldn't be better. How is the center pin made?
cheers

Link to the Otakit:
http://www.47labs.co.jp/4708.html
47 Labs utilizes the conductors of the cable for the conductive part of their two-part RCA connector. The 47 Labs Otakit is a natural for solid-core cable, and sounds substantially better than the Eichman.

I was not aware of the 47 labs connector.
Now that I've seen it, I will try to copy that.

The center pin is just a silver wire, bent at the back to keep it snug and bent slightly at the front to make contact at only one point.
I will also try to remove some of the contact area on the return wire to resemble the eichman a little closer.
I'm really kicking myself for not doing this earlier.

Version 2.0
It's like a hybrid between the 47 labs and the Eichmann. I am working on doing away with the center pin but I'm not quite there yet. It sounds really nice. At first listen a layer of glare on the letters S, F, and T has been removed. Doing one at a time and listening made me want to do the other one right away.

NATURALS.
Hi,
Nice work.
If you like what you're hearing, here's a source for even more inspiration:
AUDIO CONSULTING
Personally I had good results with stripping/skinning caps, you may want to try that too.
Cheers,😉

Re: NATURALS.
Hi Frank,
I've been wanting to ask that question for some time now. What sort of sonic differences can be achieved from this? Is it something one has to listen hard for or something immediately palpable?
BTW, if one doesn't like the sound after skinning, how does one replace the plastic back?
TIA

SKINNING.
Hi,
What you can expect is more openess, more natural sound.
The difference is quite obvious and immediately audible.
As I don't want to disrespect anyone's thread here, try a local search on " cap skinning" to find out more.
Moreover, as time goes by, I am more and more convinced that "natural materials" sound more relaxed and easy on the ear than chemicals. (Both are chemicals of course, it's just that nature seems to balance them better).
Don't get me wrong here, I am not the " Radio Nostalgia" kind of person.
I try to reason before I act...I am *very* lazy...🙄
Cheers,😉

I ordered a few materials from McMaster-Carr and built this little number today when the material came in. I just couldn't wait until I got back to show them. I only know that they work but not how well yet. These are solid virgin teflon connectors made from 1/2" rod drilled out 5/16" and 1/8" rod pin the wire is 24AWG solid silver wire with a teflon jacket. The 1ft in length. Sonic reports to follow in a couple weeks. On problem noted so far: teflon is slippery! 
Next possible set will have some kind of grips machined in them so they are easier to get off the back of the unit.

I don't want to derail this discussion, but have you guys tried no connector? In my audio experience, every connector I get rid of, improves things. With no connectors moving your audio system becomes a major pain in the butt, but for simple systems it could really be quite good.
that said, I've got way too many connectors in my system.
