Thought I'd throw this up here since it's simple and works well for me. I like to travel light most of the time, so I came up with a 3-in-one bar with as little hardware as possible.
Started with a 6' length of 1/2" x 1/4" piece of plexiglass from eplastics.com for $6; the edges are beveled nicely, not sharp. Did some measurements, then cut a piece and drilled the holes. The outermost are for DIN, the next set in from the ends are for ORTF, and the extra hole on the left side is for XY (used in conjunction with the DIN hole). Sharpie lines indicate alignment for the base of the shock mounts:
***UPDATE*** Plexiglass is indeed way too fragile so I re-fabbed with a piece of 1/8" aluminum. Still lightweight, and now indestructible:
I had to hand file a notch to allow enough adapter thread to stick through:
For the shockmounts I pre-drilled a hole through the base and used 6-32 x 3/4" round slotted brass screws with knurled nuts. I used a bit of Loctite as well:
As mounted with mics in the ORTF position; since the lyres are a bit flexible, there is a tendency for the mics to "sag" a bit. To prevent this I Velcro the cables so the mics remain level:
As mounted in the XY position and fitted with DPA UA0896 windscreens. It doesn't look it since the mics are so short relative to the screens, but the caps are perfectly aligned on the vertical:
Whadaya think?
