THE BOOK shows them to use 3 mm thick flat steel where the bolts go through - just wondering why couldn't a pipe of tube be use and then squashed to form flat ends?

If tube's wot ya got then use it - may even make it a bit stronger as you'll have more area to weld together

I put tube all the way round, then stitch welded 3mm flat to it to screw the wing down to, drilled and tapped the holes so no need to try and get a hand it to get at a nut between the wing and tyre!

25 x 5mm bright drawn seems to be lasting well after passengers got used to catching the cycle wing after potholes etc with 3mm low grade strip. It's one part of the car you have to overengineer slightly even though it may mean a few more grams.

Cheers
