Maybe this is something of a no brainer but here goes.
I have lost the original wedge piece of a razor I am in the process of restoring (my second restore ever)
So as I need to make a wedge, I want to know is there a definite guide to how thick it should be in proportion to the spine of the razor
Also is there a guide to what angle to grind the wedge at - or is this just a trial and error situation

I know I could just go ahead and take a best guess at this but I thought to myself
maybe there is a set method of working this out - and maybe I'm just over thinking this whole thing
I have been looking around on the forum and cant seem to find an answer
Your thoughts and insights are welcome

Oh and the razor - a Frederick Reynolds 6/8" about half hollow is my best estimate.
