On the fixing of bows........you'll be surprised at how grandad's or dad's bow is such a treasured item to a customer, so valuable that most folks won't spend 20 bucks to have the limb twist taken out, nicks repaired and an overall basic cleaning (you know, get that white or yellow garage event paint splatter off it).
On the "hang out" thing, yup, fun place to spend time. You'll get quite a few reitirees and regs who will hang out and never spend a dime.
If you want to have a hangout and make money, it's called a bar
One thing about your business though.........what can you write off? Is a hunting trip, your truck (with advertising on it) or your new machined riser bow you designed........can part of that stuff be considered a business expense?
It might lessen the cost of having some fun. But at what other expense?
Dunno, just tossing that out there.
