Double Bass D drop

I have a D ext. on one of my basses. I made it myself. I love it and hate it. I had a hard time with the E latch and Eb latch(which I later removed).
Why a D? Because
1. I think they're easier to make.
2. You can use a regular (and cheaper) E string.
3. I never have much need for a Db or C but dig the D on some gigs. one in particular with a guy who plays slide guitar in D and G only.
If I could just get the latches right. Crud, now I have to go to my workbench.
 
"Does your e string spindle go thru the apparatus?"
I'm sorry but I have no idea what you mean.
I have no digital pics but will try to describe.
Its very much like a C ext at the E end. the ebony sticks out to the low D. after the D the string comes off and is strung up to the A tuner(my A string is strung to the E tuner). I didn't use a pulley (C ext.s do) but it hasn't been a problem. The end of the ext. is supported by a cross piece that rests on the pegbox wall.

I have a couple of pics of D-extension. I guess Blaine's one is like this.

That makes sense to me. Heck, sometimes when I'm covering orchestra stuff that requires a low C, I just tune down to C A d g. I get funny looks from "classically-trained" bassists for doing so, but then again they may just be responding to the sound coming from my Spirocores...
 
Totally makes sense. Even the D A d a tuning works.

I met a guy, classically trained, who tuned a five string as follows....

Low C ( or B ) with an extension / A / d / g / high c

totally brilliant!!! Playing high notes in lower positions on the higher string gives more sounding string length leading to a more resonant, less " pinched thumb position sound." ( if i can use that term. ) There has always been solutions to problems on the bass. The instrument never stops evolving!

Interesting tuning. I am very close to switching to EADGC on my 5-string from (BEADG). This so I can play wide intervallic leaps in lower positions, especially because they don't sound so hot on plain guts high up on my humble bass (christopher hybrid). The Low B on this bass just ain't cutting it.

Interesting, the Extended D. Maybe Mike Pecanic can devise a fingered extension that is modular, with removable positions!

Could you make those pictures clickable so they could enlarge? Thank you for posting them.
I'm sorry, but all that I have are just thumbnails. They were linked to bigger pics originally, but no links can be found now.
They're pictures of a Japanese amature bassist's Juzek. I think a D-extension was installed by Yamamoto, one of the most famous bass shop in Tokyo.

Here are some more thumbnails.
