B4 and Micro Four Thirds Mount Specifications

what exactly you want to do?
maybe you can find something useful here http://www.graphics.cornell.edu/~westin/misc/mounts-alphabetical.html

Thanks for that. That is a good lead that has some links to what might be a good contact.
I'm looking for detailed drawings for the mounts, showing dimensions and tolerances. I can always measure the mounts themselves and try to figure it out that way. But it is best to know what the specs are to get the tolerances correct. I have the equipment to make them and just want to play. It's cheaper just to buy one (which I have), but I still want to make my own, just to learn. I'd also like to make a PL to M 4/3 adapter.

Or you could by one from us. The mechanical mounts are the easy part. It's the advanced optics that make all the difference.

A lot of people read these forums for a lot of reasons. I was simply posting an option.
I know that some people have done this by going from M4/3 to some neutral mount such as Nikon and then from that mount to B4, or some other such path. Then they try to deal with the different in the 2/3" coverage to the 4/3" coverage by flipping in the doubler on a given B4 lens. These doublers are designed to give a sharp image in the center 2/3" area of frame. They may or may not project out to the 4/3" image area and are very likely to be of poor image quality if they do project. B4 lenses are made for 3-chip cameras, which focus the three primary colors at slightly different depths. It takes advanced optics to correct for this.
I'm not trying to rain on your parade, just want to let you know the realities of the task at hand. We designed an expensive to make bit of optics for this very purpose.
