Well you guys are getting me motivated to try some more diy work on a mounting bar.
I'm not by my stuff or a camera, but I have a few solutions. First is I bought some 1" wide flat aluminum stock from Home Depot and made something like a diy vark bar or mark bar. Cut the stock to 6" or so, and drilled holes in the center and pairs an inch or so out from the center and ~3" out from the center. Got 3/8" threaded rod, wing nuts, and then used the 3/8" to 5/8"-27 adapters I have to allow the mics to me mounted in either set of holes. Using the center hole, I screwed on a short length of 3/4" wooden dowel rod (inch or two). The whole mount can slide into an a20s or a Joe Meek style shock using this 3/4" dowel. The outer holes were made at a distance so that the Milab mics put into the milab mounts makes for a 20cm DIN spacing. Using the inner holes and the milab mounts, together with a Rapido quick-release mic mount as a riser, I can run the Milabs XY.
The other mounts I have were much easier. I got an
Atlas Sound 3" long 5/8"-27 extension and a 6" extension. I wrapped both with enough gaffer tape that their diameter was more like 3/4" and they'd fit in my a20s. The 3" extension with the milab mounts yields something like DIN (21cm spacing vs the 20cm spacing called for by DIN). The 6" bar together with my Rapido quick-release mount and the Milab mic mounts yields a 30cm spacing for NOS.
That said, I'm going to look into making a DIN and NOS bar using some PVC (either bar or pipe).
I'll try to get pics up of the other diy mounting when I get a chance.
