I look through an old box of bolts and I am still picking out A/N stuff (lockwire holes, etc) that ended up in my toolbox 35 years ago when I worked on aircraft. I used to think "I'll keep that one and use it on something really special", but as time goes along, I use anything & everything now. When I look back, and compared to all the new crap on the road, most of the stuff I built WAS "something special"! I was at an auction and walking past a steel (1/4" plate) cabinet which they were having trouble getting $5 for. I bid $5 and got it. I thought it would be good to store small heavy stuff like heads, etc.. It was displayed with the doors open. When I went to load it up, I closed the doors which revealed 2 racks of fasteners (new & full) bolted to the sides! You gotta win sometmes!
