I'm still trying to figure the whole wedge thing out. I've used CA and and trying not to use it. Here are the issues I've had with it.

I glued both sides with a set of scales made from Polyester. The scales broke because they needed to be able to make small movements and the glue didn't allow that.

I tried using CA to help fill in the gaps in the wedge. The problem there is that CA doesn't look the same as the wedge. As well, this would require gluing both sides.

I like having some transparent scales in the mix a little drop of CA shows through the scales.
