I know that cosmetic things don’t improve machinery’s lifespan or behavior.
Mr Happy Dancing Bandsaw, however, was getting depressed. The main-screw for the clamp featured a polypropylene wheel with a little set-screw.
On ebay I found hand-wheels for $15, undrilled. So I had to chuck up a drill in the bridgeport and enlarge the pilot hole, then drill from the side and thread that for a retaining bolt. I used a nice 8/32 hex cap with some poly glue on it so it won’t even think to budge.
I am pretty sure the bandsaw is running faster and cooler now!
I have a friend who is often depressed and who feels that life is not worthwhile, and that she cannot accomplish anything. That’s a way I’ve felt on and off my whole life, too, and the way I combat it is by having small tasks that I can kick the shit out of, then I can stand over them, beating my chest with my great thews, roaring defiance at the world. Make sure you put down the screwdriver before beating the chest; that’s friendly advice from me to me.
