Bow Roller Wheels

Seeking a US source of supply for bow roller wheels. I'm looking for the grooved type where the chain links can sit into a depression, then the roller slopes up and away.

I'm going to be building a new bowsprit with a built in anchor roller. I thought the wheels would be fairly easy to come by, but apparently not so.

The kind I'm looking for are describe here at Steve Dashew's site.

SetSail» Blog Archive » Handling Anchor Chain

I've kinda worn out Google w/o luck.

Many thanks

Re: Bow Roller Wheels

hpeer, find out what the plastic that Dashew recomends is and buy a chunk, then have a local maqchinist turn it for you on a lathe. Machinist get a kick out of working with something that easy to work with. I think it will be easier to build your bowsprit and have a piece of plastic turned to fit rather than building your sprit according to the dimention of something you have purchased._____Grant. P.S. build to the next size larger than you think you need in case you decide to move up in anchor weight.

Re: Bow Roller Wheels

Yes, gjordan's suggestion would be the way to go, I reckon.

You could put up a post on practicalmachinist.com to find a local hobby machinist or small jobbing shop in your area.

I've made rollers out of Nylatron GSM (tough dark gray nylon-based polymer, made for making gears out of). 20 years on they still work well. Make sure they allow plenty of clearance on the axle: Nylon does swell more than most plastics when wet.

Aluminium also makes a good bow roller, tough and yet easy on the chain. Only advisable for a proper grooved type as the OP proposes, though... and needs to be plastic bushed (using bushes with flanges or heads), if it's going to last on a stainless axle.

The main thing is to go for the biggest diameter you possibly can.

Re: Bow Roller Wheels

If your wanting a grooved roller to keep the chain from twisting, then I can tell you it will not work that way. Chains will even twist in a gypsy if twisted bad enough. Also the chain will climb the edges of a grooved roller if not pulled straight on.

I was going to build a die feeder to help keep my chain from twisting but I was worried about the galvanize wearing off, as mentioned above. One just has to pull all the chain once in awhile and feed it back in straight as general maintenance.

Re: Bow Roller Wheels

Is this what you're looking for?

Windline sells them in several sizes. I think I've got some in stock.
Here is a link to Windline, scroll down to see the different sizes.

Re: Bow Roller Wheels

Make a solid metal roller, as large a diameter as possible, shaft as large as possible,
groove deep enough that the links before and after can fully rest 2 surfaces on the roller.
Flare the 0utboard guides as much as 45* off centerline to allow for veering at anchor.
IMHO

Re: Bow Roller Wheels

Thanks guys for all the ideas. I have a bunch to chew on.

Was at Bacons in Annapolis today, looking at consignment rollers for ideas. Lots of really small diameter stuff in really heavy housings. Weird.

Yeah...GOOD!
There are rollers all over Ebay. I think the groove helps if deep enough, but as said, it will not totally eliminate chain twisting. That hard ureathane is pretty durable really.

Re: Bow Roller Wheels

I believe those types of rollers are available in various shapes and sizes from most places that deal with trailers for outboard powered boats.

Re: Bow Roller Wheels

Delrin used here though I felt sure in some latter post they had aluminium ones

Re: Bow Roller Wheels

Grainier, delrin, good.

Edit...also I just saw delrin available at online metals at up to 7inch diameter, listed as UHMW.

Wonder if I could turn it down on my wood lathe?

Re: Bow Roller Wheels

You can get Delryin at McMaster Carr in 1 ft lenghts. I am in the Bahamas until June but if you find yourself in Annapolis after June 1, I would be happy to turn a roller for you on my lathe.

Re: Bow Roller Wheels

I used the bow holder off a trailer. It's a very hard rubber material with the v shape. Works great. Holds the anchor better than the old metal roller.

Re: Bow Roller Wheels

The synthetic rollers are great for silencing noise from the chain, while at anchor, for instance.
The problem that I had was that they tended to have a thin wall metal sleeve on a small diameter axle.
If this sleeve got distorted, even by just a fraction, it stopped the roller from rotating, which soon allows the chain to chew up the roller.
I know , you are supposed to snub the chain, but one quick squall on a Sunday afternoon, can create a "if i just took the time---" situation.
