So this was my first attempt at tip overlays, Certainly not perfect but it's serviceable.
I took the bulk off with a Dremel then used some small fine files to get the shape, then sandpaper from there.
This bow is a definite knock around bow and not a display piece so I am not after perfection. The previous tips were just not going to cut it though and needed to be replaced.
Initial shaping;
Then some finer lines;
After looking at the picture below I can see now that I could have used more sanding on the second white laminate on the left side to straighten up the lines a bit.
I'm not concerned about the sanding marks on the limbs so much, I think I might just turn this into my first bow restoration project over the winter months.
