If you think you are done with frame bending, you are wrong. Sadly but true.

When clamping the canopy to the frame, you will noticed that the rollers now make a terrible sound and hardly move in the perfectly aligned canopy tracks. That is because the load of the plexi on the frame stretches it out a significant amount.

It's about 1 inch in the front and half an inch on the the rear bow.

You will have to re bend the frame inwards front and back to compensate for the springload. Make it just enough so that you get a perfect alignment agin of the rollers in the canopy tracks.
Another job where patience is in your favour and a lot of fitting and refitting of the bubble is required.
Be patient, once you will be drilling the holes in the plexi, you are locked in forever.

Got to a point where I'm satisfied with the result. Notice also the side clamping with a wood strip to support the side of the plexi all along the lenght of the side bow.
