After 2 yrs of plowing with the wings I made, finally decided to add a stiffener rib to the wings themselves. They’re just 10ga steel so when snow was deep or wet and heavy I’d have 6′ blade full of snow and naturally they would deflect out. Most of the deflection came from it bending the outer rib on snow plow itself, so I added a few kickers where I bolt wings to it.
Tomorrow I’ll make some banjo fittings and tack them to top lip of plow, then I’ll weld a short section of small chain to end of each wing, and then drop the loose end into the banjo fitting. That way if they decide to deflet outward still with a full blade of snow, they’ll only deflect so far before chain tightens up and stops further bending. I had "turkey wings" on 1 of my old truck snowplows, and it also used that chain method and they worked great.

Once I had it all welded up, just lifting off outside edge of 1 wing to lift plow off saw horses, I got zero flex/bending, where before the wings would bend to a point before lifting plow up, so few bucks and an hour of time should make it better this winter without me having to bend them back after a big/heavy snow.

Then figured as long as it was up, took a picture of the 2" abs pipe over the cutting edge I use on my long gravel driveway and neighbors around here. Still alot of life in it even after 2 yrs. 1st yr it was stiff to get on and off, but now it’s "almost" to the point I can remove it/reinstall it by hand without tapping it down with a maul.
