Those look great,................................(and please take this in the helpful spirit it is given) If the pictures are telling the whole story, the grain looks dangerously bad for arrows. There appears to be a huge amount of run off . If these are strictly for decorative purposes ,it doesn't matter. But those look too good not to shoot! The way the grain is oriented , when the shaft breaks ,the piece being pushed by the string will make a lance that will be driven into the bow hand instead of being forced up over the front of the broken shaft. (unless he's a lefty)Take a dowel that you've finished that has similar grain , and give it a good flex. I think you will find it gives up surprisingly quick.
