I'm after a largish diameter (probably nylon but could be aluminimum or bronze) wheel for a bow roller but I don't seem to be able to find one off the shelf. Does anyone know of a source?

Been looking for one myself for ages, unsuccessfully. Will keep a close eye on your responses. Perhaps the right people are watching this time!

Yet another one looking for one. I picked a genoa car roller at a jumble but it only lasted half a season
 
www.directplasticsonline.co.uk have a range of plastic types and brief descriptions of their properties------Rods up to fairly big diameters.

I used "Tufnol" a couple of years ago-----excellent but expensive [relatively].

It's easy to turn if you have a lathe, or know somebody.
 
Is this for your Nauticat? Take a look at the Hallberg-Rassy online shop, go to "Deck equipment", then "Anchor equipment", and scroll down to find spare rollers. An email enquiry will provide size information. I've used the shop several times for spares for my HR, and the service is good.
 
I made my own from Tufnol but if I was looking for alternatives I would consider a boat trailer roller. One made for aluminium boats out of hard plastic.Cheap and easily modified to suit.
 
Brent Swain (of Origamiboats fame) makes his own custom rollers using high density polypropylene from kitchen chopping boards. The method he uses is to roughly cut-out a few disks then 'glue' them together by flaming the surfaces to be mated with a blowlamp until they just begin to melt, then firmly clamp them together. Repeat this until you've achieved the required thickness. Drill a central hole and insert a suitable long bolt. Tighten the nut and clamp the shank of the bolt into a lathe (preferably) or a pillar drill. Then, using a sharp tool, profile the edge of the sheave to the desired shape. He also makes his own (indestructable) rigging blocks using this technique.
 
I looked for more than a year - then came across a sellection of rollers at Towsure designed for boat trailers to support the boat V part. Fits perfectly but only in Black ! and very cheap.

Cheers
 
I have just got a rod of Delrin Acetal Homopolymer from www.theplasticshop.co.uk. The diameter is 90 and a metre long. The cost was around £70-80. I have to get it machined however it should make plenty of spares. Having seen the incredible prices on the HR site I now wonder if it is the right stuff. They must be using another type of plastic to justify the prices.
 
I also use 1/4 inch flat head bolts to hold the plastic cookies together . The countersunk flat head makes one side flush. The nuts I countersink, by heating them red hot, while on the end of a bolt, and push the hot nuts into the plastic, the bolt in the hole centreing them. Then I put the bolts in and screw them tight from the flat head side.That leaves both sides flush.

Hello,

On my Oceanis 40, the only spare bow roller that I found on the web was Osculati reference number 01.219.95 available from many European online shops . The size is 88 mm (not the external diameter) which is fine for the available width of 90 mm on my boat anchor assembling. In fact when I was reading this thread, the Swedish firm also has a roller with the same width but with an internal diameter of 19 mmm which is too large for my boat. The internal diameter of the Osculati part is about 13 mm which is also fine. I use it with 10 mm chain. Here is a link to my site where I list "difficult to get spares" for my Oceanis 40: http://www.vela-navega.com/forum/viewtopic.php?f=8&t=21

Regards, Luis
