I sourced the Hansen Rivet Co 3/16" Semi Tubular Rivet Driver, that Proper Tooling will correctly mushroom the open end of the shaft.
The Next problem is Properly supporting the "BACK" side (aka Roller side) of the Shaft-Rivet combination.
The Roller side has a flange and raised center. You Should properly support the Center of the Raised portion of the Shaft-Rivet, NOT the flange, as by applying force on the flange it can bend and pinch the plastic roller and causes drag or a non rolling roller. I chose to fabricate a custom support using Brass and a Lathe, the support has a raised center "NUB" that contacts the center of the shaft-rivet and a recess for the roller that then Self centers the assembly - PERFECT tool.
Notice the nice Mushrooming of the semi tubular rivet aka Clinched end of the roller shaft.
Spins Like Butter, then a little Lithium Lube.
You Can Do it.
