Anchor rollers on my Jeanneau SO45 look pretty worn to me. Unfortunately I don't know the difference between 'nicely run in' and 'ready to fall apart'. The delrin/plastic stuff seems pretty tough to me, but obviously there's a lot worn away.
The boat is in Greece and we do a lot of anchoring during May - October sailing season.
New rollers are £85 each, should I take a pair out to fit next spring?
Or will they last a few years more?

Depends what you mean by 'a few years more' but I'd buy new rollers. But then I'd find someone to turn new rollers for me.

Start a new thread on where to buy, have made, new cheap (but good) rollers. I cannot believe your yacht is unique on the forum - someone may be able to measure for you, owners forum? If your yacht is in Greece - simply send me an airticket and I will measure up for you :).

I changed mine on a SO37, they were in much the same state. The replacement came with a SS tube for the inside of the roller so there was no wear from the pin that keeps it in place. The original didn't have this hence it didn't roll that well - the chain and anchor were effectively sawing on the roller each time we anchored and retrieved it.
 
By some delrin from plasticsdirectonline.co.uk and wander around your local marina to measure, then find a 'friend' with lathe.
Easy stuff to machine and 'Time spent on the lathe is not deducted from your life span' i.e. it's fun.
 
I don't have a lathe, so I got some sheet delrin/nylon, cut out several discs of the appropriate sizes, and glued them together with resin. Mine are seriously big rollers, running on an 1" dia spindle.

If I were you, I would renew them sooner rather than later.

I find putting jobs off doesn't pay. Before you know it you find you have a long list of outstanding jobs and that can be very dispiriting.
 
If you are in the UK then Versatile Marine offer a custom service at sensible prices. I would DIY it if I had a lathe and competence.
 
A warning with worn rollers: if the 'groove' in it (for the anchor shank) gets wide enough that the chain will just fit in it cross-ways, the chain will jam. This in turn broke the electric motor on my windlass (not that its been very reliable). Replacing the roller is a lot cheaper!

I just used the normal two part epoxy resin. Can't remember the exact brand, and it's not to hand. Being a belt and braces type, I also fitted three tie-bolts, to hold it all together.

I actually wondered if you needed glue at all, if the various discs were secure enough. It does not matter if they move. You don't need a lathe - just a set of hole saws and a drill.

I think you need to drill the centre hole, for the shaft, half way. Then drill for the full size right through. You now have a disc with a half drilled shaft hole and a guide to finish off the shaft hole.

If you make a roller out of several separate discs, as I have done, they must be held together. Either by gluing or by bolting, or as I did by both. If they're not securely fastened, all that happens is that the discs are forced apart by the chain and/or anchor, and the roller jams between the cheeks.
 
Thanks for all your advice. I now intend to order the genuine Lewmar rollers and fit them before next years sailing season.

I looked at buying acetal rod, costs about £60 for enough 80mm diameter rod for two rollers.
Since I don't have a lathe (or a pal with one) and would have to pay for machining, seems to make sense to get them off the shelf.

The home made discs and glue solution sounds more likely to fail than the worn roller I already have. The chain pressure acting to split laminated discs must get pretty high.

Ah! But you're willing to spend £170 . ?
My home made, from discs, rollers, cost nothing and have been in heavy use now for a few years. I get great satisfaction from making things myself. Each to their own. ?.
