A couple of the jigs I made to help with canopy frame tweaking:
The round pieces were pulleys from a modified band saw that I inherited. I rebuilt the band saw with new appropriately sized pulleys to bring down the speed to what I wanted. They worked perfectly to help get that frame into a shape that I could live with. From an entry/exit, operational, and appearance standpoint I prefer a sliding canopy, but it is a challenge to build.
