Not the best picture to assess your fine work but heh you got it done and from what I can see made a good job of it, well done!
One of my cheats with the wedge is use a nice long piece of wedge material so you have an handle to hold whilst sanding it down to thickness.
Next I cut the wedge section off, coat with something to seal it then pin the wedge end.
Now I wrap some tape around the pivot end and sand the wedge end to shape, polish and pin the blade in...done!
