The following picture/drawing is a starting point for my DIY capsule attempts:

(copy link to new window to open) - If it doesn't let me know, my ISP is being a bit of a pain at the moment and I'm having trouble getting to geocities to confirm it's uploaded correctly.
Anyway, this is, hopefully, a to scale representation of the Neumann KK67 capsule.
I've taken this picture:
http://www.timcampbell.dk/mic/N_KK67_08.JPG
from Tim Campbells site, and then drawn over it to give, what is hopefully, a to scale representation. Now I just need to know the original dimensions of the capsule before I can start.
I've made a couple of assumptions about the capsules construction, Tim C, maybe you could post whether these hold up or not.
I'm assuming that, after viewing the pictures, that the two halves of the capsule are identical, however they are assembled so that one is rotated 45 degrees to the other. (This is how I've drawn it, if you were to rotate the picture on the right 45 degrees counter clockwise it would be the same as the one on the left.) I'm basing that on the various pictures on your site of the capsule deconstruction, and your own clone. Question is, should it be rotated 45 degrees clockwise, or counter clockwise? If you look at this second picture here:
http://www.geocities.com/mejafu/miccapsule2.jpg
This is rotated the orignal capsule counter clockwise, and you can see how it effects where the holes that go all the way through are, when compared to the original picture above where I rotated the one on the right clockwise.
The other assumption I've is that the layout of which holes are drilled right through, and which ones are only half through remains the same on both halves?
Are these correct assumptions?
In order to make the above picture a 1:1 scale picture I simply need to now the diameter of the KK67 capsule - I'm guessing in the 30-36mm range somewhere?
The other information I need is:
1. the depth of the backplate
2. how deep the holes that don't go all the way through are drilled, and if they are all drilled to the same depth?
As I said this is only a start for me. The main thing putting me off diving in at the moment is that I don't have a metal working lathe to machine the parts. Though I'm pretty sure that one of the highschools I teach at has a metal working subject, so hopefully I might find another teacher there that might have access to appropriate tools.
