I am looking into building a horizontal masking system (motorized) and found the av-outlet.com website for some building materials. Can someone provide a detailed list of necessary supplies to purchase from av-outlet.com or any other vendor to ensure I order the correct materials? I guess I am really looking for a "kit" to make sure I have everything needed and all I have to do is build the frame to house the motor, etc. Also, if there is a great and straightforward (with pics) instructional guide on the construction of such a system, I would like to know where to find this as well. My current screen is 110". Thanks.
