binding barrel bolt meets a carriage bolt

[JEK5019]

thanks cropwell.

so i looked up the wallpaper seam roller you had mentioned - and the design i am working will work just like that, in fact! but unlike many of the designs, i came across - where the roller bracket is on one side only - my design will be built like an axle.

attached are several of these wallpaper seam rollers that more or less fit my goal and operation.

in my design goal - i am wanting to avoid any welding/sanding finished. i would prefer fasteners - but with no drives. very clean!
