Default Don't cut any metal yet

I'm starting to think that the interference / rubbing is going to happen and that the best solution is to round the bottom edge of the canopy frame arm so that the strut has smooth surface to ride up on. Or there is something wrong with the parts that I have.

I wouldn't cut or shave any metal yet until you're certain all else is according to plan. I don't recall the interference you describe being often discussed.
Can you post a picture of your strut attachments (top and bottom) and where "the rub" is?
