I was trying to make a new WA handle to replace poorly made handle of Tanaka petty. But I'm struggling to create perfectly flat surfaces for glueing.
Here's a picture to illustrate my problem:
You can clearly see the gap between two parts. No matter how hard I've tried, from one or the the other side there are still small but visible gaps. At first I just used sandpaper wraped over some blank of wood. Later I tried flatting surface with DMT coarse plate… but still can't achive gapless surfaces between 2 pieces of wood.
Another unrelated question — how can you cut a really thin piece of wood to be used as spacer? I saw a lot of custom handles where wood was used instead of metal of horn. But I can't even image how to cut such thin and even pieces in home environment.
I have zero woodworking experience so any advices are highly appreciated
