Dick was a good friend of mine. The tapered pin I put the bushing on locks it into place and I spin it lightly against the wheel just to clean any displacement of the round face of the bushing so it will be free in the hole. Sometimes when you stake the bushing it will displace a little on the surface. You want to use a light touch when you do it. when I get a knife together I set there and open and close each blade 50 or 60 times to let everything seat in before I clean the backstrap up on the grinder.I'm so isolated out here I never got a chance to learn much from other knifemakers but I owe all this bushing stuff to Dick Hodgson. I don't do it exactly like he did but you have to figure out what works for you. Hope this helps.
