Avi, Your photograph shows radial scratches on the Blank.
These indicate that you have difficulty with your Abrasion Finish.
CA will fill the grooves, and subsequent sanding will smooth the Surface, but it will not hide or eliminate the Scratches, that are now covered by "X" coats of CA.
You should concentrate on eliminating the Scratches on the Blank.
With regard to the chips, they could be the result of Technique.
When using a Temperamental Material, such a Coarse Burl, one has to be careful removing material, else sections and chips will pop out.
Fine Cuts with a Sharp Tool, probably a Skew is the best way to attempt any Course Burl, another way is to seal the Burl with CA, progressively as you turn.
Elimination of Chips, is a lot easier, than trying to repair one.
Remember CA will fill the void,so that you don't feel it, after further sanding, but being Clear it will still show.
It is a shame, but take it as an opportunity to develop and improve your skills.
I don't know if you have had any tutoring, or if you are completely self taught, but it may be worth contacting your local group, and seek some hands on assistance, and skill building.
Brian.
