Thanks, gang, for the responses; and Islander53, thanks for taking the trouble to quote and respond even though you don't seem interested in the topic. I can see what y'all mean by doing it for the joy of it. The detailed work would be fun and another form of artistic expression. I'm not much of a piddler/fiddler, so I would not want to do anything like that myself.
There is one cosmetic thing about one of my ukuleles that I would like to change. I would like a slot style bridge instead of a tie-on. I know that is purely superficial, but I think it would look great. I'm just worried that it would hurt the finish on the top or something. Wondering if it is worth it to have it done, or should I just stop thinking about it.
