I have bought the Snake River Prototyping tray and arm assembly. But they didn't attach any instruction. Can anyone help with ideas how to assemble this arm?? Thanks in advance. http://img846.imageshack.us/img846/4829/loclinearm.jpg[/img] and then connect to this tray... http://img221.imageshack.us/img221/9470/traym.jpg[/img] I wish SRP would have instruction manual for this...
