Our German exchange student would like to build a gun and shoot it while he is here. Taking it home is not going to happen. I'd like to find something inexpensive that I can buy or a generous person can donate. I'd even be willing to send it back to whomever provides it this summer, completed. He'd like to do some metal filing, minor engraving, wood finishing, rust or blackening, maybe case hardening. I have the tools and equipment but not a lot of disposable cash to come up with something like this for him.
