Thread: Trouble Flattening Inside of Scales At Wedge End

Thank for the scraper suggestion. That seems like it would work better since you have more control of where the material is being removed and the amount.

Well, the wood scales I'm working on don't have a wedge yet. I can see the gap when I put the two scales together so I know they aren't perfectly flat.

It does not have to be a crazy strong bond, there will be no force trying to separate the joint, just enough to hold them together. So you can shape them.
You can glue a block of wood to the outside of your scales with rubber cement to have something to hold on to and lap the insides flat on a sheet of fine sandpaper.

I used the paper and glue before cutting and shaping the scales. That is why I mentioned sanding off paper/glue from the inside of the scales in the first post. Not a big deal though.

I believe my first mistake was not using even pressure when sanding off the glue/paper from the inside of the scales. I've thinking I should have done something like you mentioned at the end with a block. I may try that next time. Thanks

This is how we learn! I have been playing in the shop/s for over 70 years and still am finding how much I yet need to figure out.
Like for honing, a dead flat surface is best. A sheet of granite or glass is a good base for sand paper. I use a bit of spray rubber cement carefully to hold the paper down. If I just use water under and over, the edges curl up and then I do not have a flat surface to lap my scales upon.
