binding barrel bolt meets a carriage bolt

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!

Maybe a domed starlock washer, which would push onto a solid shaft, would fit your requirements.

this looks impressive. i guess my only concern would be - if you accidentally dropped the tool, say onto the floor and the floor met the roller - would these things just pop right off?

if not, then these might actually do!

In my experience you have to destroy them to remove them. If you want the shaft to be fixed solid then your solution lies elsewhere.

but wait - the solid shaft needs to adhere to the channel - no motion - only the roller opertates.

that's where the drive screws came into the conversation.
