Sideways mount
 

I have need to shoot with my camera (an HV30 + Brevis35 + rails rig) mounted on it's side so as to shoot full-frame "vertical."

I'm looking for some ideas as to the best, most solid options for getting this thing on it's side and still retain the basic functionality of the tripod.

I'm looking for the same thing for my HMC150 and have not found a "product" yet.

Got some greenscreen work in a couple of weeks and want to try the vertical framing to get a better use of the camera's resolution.

I will be visiting my local hardware store to buy a 1/8" thick piece of metal about 3-4" wide and 12" long, bend it into an "L", drill a hole and get a 1/4-20 screw for the camera and a nut to weld for the quick release plate to mount to.
Should cost about $5.

I thought about using wood as it's way easier to work with but the metal will hold up better.
Maybe I can make a few and sell 'em!! HaHa!

So here's the update...machinist friend not needed...Home Depot run today found strapping metal for house framing in 2" wide already bent into a perfect L. It's about an 1/8" thick and even held in my heavy vise I couldn't bend it using all my weight.
Bottom is about 4" and top is about 8". Cut about 2" off the upper and smoothed the edges. Got 1/4-20 nuts and bolts (pair) to mount the QR plate for my Manfrotto and the upper will get a 1/4-20 thumbscrew for the camera and a smaller bolt brazed to the bracket for the stabilizer pin. Once assembled, it'll get a coat of primer and black paint and total cost will be $27 for a pair (friend wants one too) with all hardware and paint!

Here's the finished. It's not the prettiest but not too bad (I'm not great at brazing!)
CHEAP and functional! Still allows full use of the tripod and when I need to mount to a teleprompter for greenscreen work, it'll work just fine!
