It is often difficult to see how well wood has been snnded until you put the finish on it. the lovely maple neck on Torsten's instrument revealed sanding scratches from the coarse sandpaper of the bow sander. Each coating of French Polish seemed to make them stand out more- so today I sanded all the finish off and started again. First 220, then 310, then 410 and finally 500 grit. Now I feel better and that neck will be plenty smooth.
220 grit to take off the finish and remove the scratches.
The first application of French Polish and now scratches can be seen. We are on the road back now.
