There are heaps of different size and styles of rollers from different manufactures that i have seen in over 47 years as a boilermaker. I will see if I can have a look tomorrow what i have that comes close to the dimensions you have described. Some of the knurled rollers that are used on fluxcore wire are made in 2 halves split at the grove and held together with screws, that would make it a bit easier to knurl each half then clamp together align up the knurls and drill for screw holes. Just some of my thoughts for now.

Thanks Trevor
Trevor,

Thanks for the suggestion on the split roller - I never thought of that option.
