The day I found out I'd been crimping pins wrong for 2 years

I was wrestling with a D-sub connector on a King Air last Tuesday and a senior tech walked by and saw me using the wrong color positioner on my M22520 crimper. He pulled out a scrap pin and showed me how the insulation grip was supposed to look after a proper crimp - mine had been smashing the wire barrel flat every time. Anyone else get caught in a bad habit like this that just made sense after someone showed you the right way?

First time I got chewed out was over a BNC connector on a surveillance system. I'd been using the same die set for everything because it fit and I didn't know any better. Guy showed me the proper crimp profile and how the hex shape was supposed to collapse the barrel just right. Felt like a total idiot but at least the cables I made after that actually held up. It happens to everyone sooner or later.

Picked up a proper crimper for RG59 after a guy showed me how the compression connectors were supposed to look. The first one I did had the center pin barely sticking out and the compression ring was cockeyed. He made me strip back the jacket and foil just right, then trim the center conductor to like an eighth inch. The finished connector looked clean and seated solid. Never had one pull loose after that.
