My 13 y/o daughter has really wanted to contribute in the building of her uke. She took on the final assembly this week as well as putting together the selector switch and potentiometer wiring. Turns out she does better solder work than me I believe we have a future luthier here!
Tiny nimble fingers. That's why they use them in sweat shops in China.
All kidding aside that's great she's involved. Maybe you can have a shop helper? Good bonding time and teaching her a really great craft. I'll agree with Gyozu though, she looks like a lovely young lady and I'd hate it if she got hurt. Get her some eye wear and get her to tie up that hair. A buffer could really hurt her. I've known a few knife and sword makers who've had steel thrown across the shop by a buffing wheel.
