I have 2 pieces of olive wood blanks that I have made for scales. They are about 1.5"x6", about 3/32" thick. I am using these for a 5/8 half hollow razor. I have been researching about making scales, but have a few questions:

How thick should I make the scales for them to bend properly and be strong enough?

Should I put the scales together before I finish them: glue the wedge in and pin them or finish them first? Not sure how much difference the finish will make as far as thickness; will probably use some type of poly.

Appreciate any advice on anything I need to do with assembly to make sure the blade centers in the scales.

What measurement should I use for the position of pin on the wedge?

How would I check the scales to make sure it is ready for finish (scratches, etc)?

I am doing these by hand, if that makes a difference in the answers.
　
Thanks for advice
