Onto the badly cupped inserts . I removed them all and tried filling them with super glue.
Unfortunately this did not work too well as a lot of them did not dry clear so onto plan B which is to sand them flat .
This is very time consuming and tedious work but they look a lot better compared to the one I had not done yet in the 2nd pic . They are just sitting in top of the holes in this pic, not glued back in yet


I have 9 left to go now .. hooray .
