Replying to Need suggestions for ski chair....

I am building a chair for the shop I work at out of some old, brightly colored skis.  Its going to be a rocking chair, so I need to have a pair of skis bent into a somewhat U shape and have them stay that way.  Anybody have some suggestions?  I have a few ideas of my own, but I just wanted to see if anyone has some experience in bending a ski and making it stay that way.I was thinking of heating it up somehow and maybe it would stay bent?  Or making a bunch of cuts on the bottom side, bending it, then filling it in with epoxy to make it stay bent....  Let me know what you think!
