Inlays on Maple is rather tricky. The slots have to be perfects because you cannot successfully fill them with saw dust and CA. The fill will get darker than the maple and the result will not be nice. But it can be done. You just need to be very precise. take your time. For this build
I did just that - although my fingerboard was 17" radius and I used wood for the blocks. The link will take you to the right page, then you should read the next two or three, I think.
9.5" radius is a lot of curve. You need to make your block inlays quite a bit thicker than the usual 2mm. On this thread
I elaborate on that point.
Hope this helps. Good luck, have fun.
