I am a Master Trainer for the US Army. I am also an Artist and "Amateur Engineer". I am always tinkering or building mechanical and elctronic things. I have a full sized shop,(not a glorified garage),that is littered with just about every tool. ("littered" is the best word here!) I build most of my machines from scratch to include a CNC Router and multiple automated gizmos. I use my own machines to build much more technically elaborate devices for use on everything from vintage automobiles, to cutting edge small arms, to artistic sculptures. I believe you should keep your brain and hands busy at all times possible...it will keep you out of trouble!
