Wing stays
 

Hi folks,has anyone got a decent pic of the front wing stay fixing,or mods they have made.


Thanks.

Hi Paul,
I made a bad construction in the first place, so I re-made my wing stays in April. I ma now very happy with them. Here what I have done:

You can use the translation function directly on the blog (right menu). It is translated by Google, far from being perfect, but understandable...

... ah no, sorry, I forgot you were fluent in French ;)

Good luck!

As it happens iv just been doing mine. I painted them last night and hopefully fit them on tonight them I can get some pic's

Merci mes ami.

Je parlez merd se bon Sylvain .:D

I have standard book design wing stays. They've broken at the weld seam between the tube and the steel band 3 or 4 times. Each time I just redid the weld and promissed myself to build sturdier ones soon.

Sylvain, so how are your new ones different from standard? Thicker plates?

Recommendation was to use 5mm instead.

I have used 5mm strips instead of 3mm for WS4,5,6, and my WS5/WS6 assy is in 1 piece.

As the books recommends, I also made a "t" cut on the strip, so they go into the round tube, and they don't "pull" on the weld: the strips are naturally blocked in position into the tube, the welds just maintain them in place.

All other plates (WS1, 2, 3) are also 5mm thick, and I used 20mm tube and not 19mm, but I don't think it makes much difference.

In order to make the tubes easier to place the lower plate WS1 (I couldn't go anywhere with the book's design), I made WS1 bigger and triangular, so I could place each tube independently on the plate on the right position, and each tube rests on the plate, and not against each other as on the book design.

It might be overkilled, but it is steady.

There is an upside, and a downside to this:

Upside: Positioning the bases of the tube this way places the rear tube further back, so the angle needed on the rear tube to go around the front brake line (13° in the book) is smaller, and I just bent the tube manually. No need to cut and re-weld as on the book's design.

Downside: Positioning the bases of the tube this way places them further away from each other, so, in the same way as the rear tube is further to the back, the front tube is further to the front than with the book's design. The consequence of this is that the angle you have to tighten the ball joint's nut that old the lower plate of the wing stay WS1 (space between the front tube and the rim) is much smaller. So it is long and difficult to screw the nut on, especially wit my torque wrench which is quite thick.

But the wing stays are now very steady, they don't vibrate at all. So far (about 2000km), they don't show any sign of fatigue.
