Fabricating the struts. My thought is that the aluminum block can function as the trunnion /rotation point. The strut itself extends into the block. The plate that was included with the strut to attach it as a fixed gear is bolted to the aluminum block and the toe-in can be adjusted with the tightening screw. The 1/2" aluminum round bar stock will be secured with a set screw and then set into bearings that will allow for rotation. Should be plenty strong enough even if I get up to the 50lb range (Which I really hope I don't).
Now to get this moving!
