DIY Chroma Key mount
Posted 09 November 2005 - 10:20 AM
So we recently built a mount for chroma-key paper in our studio. It's pretty simple right now: A ten foot steel bar is supported ten feet from the floor by pipe fittings that come off of the wall, attached by two flanges. At each end of the steel bar is a union so we can take the bar down easily to change the paper. However, now we have two related problems:
1. We have no good way to keep the paper from unrolling to the ground from its own weight (right now we're just using binder clips! Not good!).
2. We need a way to roll the paper up and down as it can't remain down all the time (students would destroy/trample/tear it).
Has anybody ever built their own chroma-key paper support? I'm thinking we need some kind of cam that fits inside the paper roll? Any ideas would be appreciated! Thanks, Mike

As for rolling it up, sounds like you may just have to do it the old fashioned way. If that isn't practical, you may be able to attach some sort of makeshift handle onto the inside of the roll that will make rolling it up easier.

This is mounted in a multi-use University studio. We have to be able to roll it up at least three or four feet after every use to access an electrical outlet that is unfortunately behind the paper (and to keep students from trampling it when it's not in use). So getting two faculty or staff members on top of ladders each time to roll it up and down and clamp it is kind of impractical.
Although the pros may cut it off each time, this is definitely not a "pro" situation. We're on a budget and this paper is not an expendable for us.
So yes - the crank pulley/winch system is what I'm thinking along the lines of. Has anyone ever made one of these or could you imagine what one might look like?
