Rear Projection Assembly

 

Install 3" PVC 3" long pipe into a floor flange, and install a 3" PVC male adapter onto this. On the outside bottom of a 20" flower pot ( Home Depot part number 087404560200 ) center the floor flange and drill four mounting holes. Mount the floor flange on the outside to a closet flange extension ring on the inside. Cut out the bottom of the flower pot using the inside of the closet flange extension ring as a guide. Drill mounting holes in each of the four tabs on a SPEEDTRON 20" photographic light diffuser (SPEEDOTRON part number 25529). Cut out the diffuser that comes with it, the outside ring is only used. Tack the corners of a 2' by 2' Da-Tex rear projection screen (Da-Lite Screen Company 800-622-3737, www.da-lite.com), polished side up, stretched between two nailed down two by fours. Apply super glue to the bottom of the 20" light diffuser ring, press the diffuser ring, glue down, onto the rear projection screen. Hold until set up. Align the diffuser ring with the rear projection screen on the top lip of the flower pot, mark where the  mounting holes are in the tabs on the diffuser ring on the flower pot. Remove diffuser ring and drill holes. Set aside, the rear projection screen is the last thing to be mounted in the assembly.
