Sofa-bed partial FAIL.
Two steps forward, one step back. My mechanism to raise the back of the sofa-bed doesn't work as well as I'd hoped. It does raise the back, just not far enough. I'm moving on to Plan C. Plan B would be to keep working on the mechanism until I get it right but I've already spent enough time on this. I know I can get it working but I've got a van conversion to finish. Plan C is to use another actuator to raise just the back. I really wanted the sofa-bed to work off of just one actuator. Maybe I'll come back to this problem some day. I've already drawn up a whole new design today while stuck waiting at the doctors office. It was either that or look at "People" magazines that were so old the Flintstones were on the cover.

Before taking the current lifter apart I created a .avi file that shows it in operation. The back is propped open so to see better. In operation it would be flat like this.

Caution - large files.

Since I was making .avi files here is one showing the actuator in operation. It's kind of loud. Not that bad in real life.
