The $24.00 dollar shoulder support with Rod mounts are getting a few questions as well as the recent Quick Release adapter posted on this blog. Here's a look at how i'm using these recently purchased items with my gear.
First a quick look at the cheap Quick Release adapter. It's not a standard QR adapter with a 1/4x20 thread already tapped in. Instead I run a beveled screw through the top of the adapter and place a bolt underneath. To keep the quick release adapter from shifting around I also used thin double sided tape between the adapter and the stage of the flycam nano. To prevent the nut from coming loose, I also have a washer + lock washer.
Second common question i've been getting is how to mount rods to the cheap $24 dollar shoulder support. To get the basic foundation setup, you'll need an adapter plate. This type of plate is commonly used under a rod rig so that it can be placed on top of a Tripod of Fluid head. When purchasing a basic set of rods or any rig, find out if one will be provided. If not you can buy one separately here: http://express35.com/tripod-mount/1054/
After mounting the adapter plate to the shoulder support, I can then position any set of handles, build up an offset stage, have support for a follow focus, matte box, etc. You can also find a basic set of rails with DSLR base plate, and Tripod plate here: http://express35.com/rail-system/295/
