Manual Uncapping Table

I am thinking of building my own uncapping table complete with a frame holder and chain belt that will move the frames to the extractor. The chain belt could be controlled with a foot switch. It would allow workers to uncap with a scratcher, place frames on the rest (on belt) and occasionally, they will be pushed to the extractor as they fill up. It would be built long enough to hold 5-6 boxes etc...

Is anything like this around? I would love to see/hear your thoughts on this. The bottom of the table would be angled towards a valve that could hold the honey and opened allowing honey to flow into a bucket.
