I build stuff out of fiberglass. I start by making a "plug" (a model) out of styrofoam, cardboard, or wood, then cover it with plaster or bondo. When the shape is finished, I make a fiberglass mold that I can use to cast pieces from.
I shoot Skeet, Trap, and Sporting Clays whenever I get the chance. Before getting my 74 I shot much more often though.
For my 55th birthday this year I started playing drums, the full set. Hope to find a classic rock band that needs a drummer in the not too distant future.
I also have a full olympic barbell gym in my basement that I use in cycles...dedicated for a period of time, then slack off...but I always come back to it. Best ever squat was 305 for 5 sets of 5 reps.
I tend to dive deep into my hobbies, and am very passionate about them, but I actually have too many at the moment and none of them are getting the time they deserve but I am not willing to give any of them up.
I'm also into building custom golf carts, restoring John Deere garden tractors (I'm still a farm boy at heart), antique pickups (I have a totally original `50 Ford), helping my wife with her gardening/koi pond, astronomy (I have a big *** telescope), and I'm an IT guy so I like tech stuff.
