You may have just provided a good formula. 1/2 tang thickness at the pivot hole for the thick end, 1/2 thickness of the scale for the thin end for the rough wedge blank. Now all that we have to figure out is the length of the wedge to get the finished thin end final thickness down to about 2/3 of the thick end like you did on those ivory scales. Then we shall have our angle. Of course, we still have to figure out that angle of the taper of the tang from the thick part of the spine to the pivot.

Sand that down to a wedge shape to about 1/2 the thickness of the scales

Adjust to fit because of the length of the scales you made

Problems are normally that your wedge is TOOOOOOOOOOOOOOOOO thick go measure the Vintage ones for comparison most are less then .065" at the end of the razor..
Spacers vs Wedges: Spacers do not allow the razor to Flex correctly, again go look at a Vintage razor and see what I am talking about.

All this is quite obvious if you just take the time to see what those old farts did over all these years


This is a thread I did recently but I can't find it on here so here is a link to it over at TSD, this might help explain with PICS to what everyone is telling you

Edit: I did NOT address the Scales themselves here although I do in that thread, regardles on material used it has to be thin enough to be slightly flexible...
