My anchor rollers were in pitiful shape probably because the rode was all chain which takes a toll on the rollers. I did change my anchor and replaced my rode with 5/16"chain and 9/16" 8 plait rope which is what is required for my windlass and should resolve any more wear issues on the rollers.

Here you can see how the roller basically got cut in half due to wear and the material used was rather brittle. I looked for replacements however finding the correct size (hole diameter & width) was impossible not to mention expensive. Had some type of phenolic material left over at the shop so I machined it to my liking. Yes I have 2 roller on the stock set up. Made them slightly bigger and better shaped IMHO. Will try them out tomorrow and hopefully they work as expected. If not, no big deal, back on the lathe and modify to suit.
