Isn't it the pits? Just about the time we think we've got things figured out, our bodies start going south on us. There was a time when I could swing a hammer 12 hours a day, and not have any issues...... but those days are past. Thankfully I listened to some "old timers" who warmed me in my younger years that one day I'd probably not be capable of swinging the hammer like that.....which is the reason I have the air hammer and press in the shop. I'd like to keep doing this for as long as possible. All the best to you Dan!
