You're actually going to give this bow to someone? Is it someone you know? Are you selling it? If it breaks and hurts someone, you could be in for a huge headache.
Depends on how he goes about it. I make a lot of things...the wire figures I make can be seen in the trading post...just about all of my customers sign their name to a sales slip which has, at the bottom, just above the "sign here" line, a statement that reads "By signing, customer agrees that any damage to property or person as a result of use, display, or storage of (the item) is the sole responsibility of the customer. Customer agrees to accept full responsibility of ownership, use, handling, and storage of (the item)." All states vary, but in Texas that stands as a complete release of liability.
I would have advised against it, but had the buyer insisted it would have been cut the same way. The customer is always "right"...even when they're wrong. I actually had one guy bring his bike to me and list symptoms and, instead of having me diagnose the bike, gave me a list of things to do as "corrections"...he was somewhat distraught when none of the tasks he asked me to performed fixed his bike. Of course I cut him a great deal on doing to correct repairs...but sometimes it's better to let the customer learn the hard way.
