heh blast it - i don't have the measuring equipment...
It'll be pretty unscientific this one... i'll save all measurements of the WB (i.e. width, height, size of channles and so on)
Too bad i don't have a digi-cam before i seal the sucker up... I don't have much time these days so development is going slowly.
in a min or two i'll post a pic with measurements...
Btw, i lock em together with epoxy, it says that no chemicals will dissolve it and mechanical force is needed so im pretty confident it will hold the sucker together
