How much would you charge?

So at the end of the day, the owner wanted me to make the cap. I told him I have a $50 minimum to do any machining. He agreed to that. He is a fellow disabled combat veteran, so I gave him a discount and charged him $40. He was very happy.

That's awesome, everyone enjoys a happy ending where all parties are satisfied.
I gave some advice in this thread. But I'd like to add something, my personal code of ethics dictates how I approach things, I'm professional grade, never been out to screw anyone for any reason. I can't count the number of service calls that ended up being so simple that I didn't charge anything. I miss being my own boss, I guess the security of my current job has become more important as I age, no decisions to make, just show up.
