Replacing Sheaves on Gibb Genoa Sheet Car

[Cat-a-tonic]

Hi,
I have genoa sheet car travellers on 25mm T bar on my Prout catamaran, dating from about 1986. The sheaves are shot and I'm looking to replace them. Gibb appear to me to be out of the business so I'm looking for alternatives.

There's a Barton product at about £45 that looks to be usable on my 25mm T bar but the car length is much shorter (80mm instead of 110mm) than the Gibb and the plunger size is smaller which would lead to a sloppy fit on the track.

Ideally I would like to just replace the sheaves but can't find any suitable spares (max dia 44mm, min dia 33, width 33mm, 9mm sleeve running on a 4mm spindle).

Any ideas?

any good plastics fabrication shop should be able to make them up for you, specify oilite bearings ( bronze soaked in oil, basically)

You might try:

www.rigrite.com

or Zepherworks (don't know the website)

Cat-a-tonic, I have the same problem on my Prout Snowgoose. What did you decide to do to replace your bad sheaves?

Hi Tom,
I confess I'm still living with the old failing ones. Had a good look at the www.zephyrwerks.com website. They look like a good professional source but suspect that the cost of having the sheaves custom made plus new pins plus carriage to the UK would equal the costs of the Barton replacement. The Barton product is shorter at 80 mm rather than 120mm and has a smaller plunger pin diameter so not ideal.

I'm still mulling over both options.

Have you seen any other options?

Regards

No, I thought I would check with you first -- hoping for an easy fix! I actually have a broken sheave so I need to find a solution quickly. I will check with Rigrite to see what they can offer and I am heading up to Annapolis on Friday and will see what I can find up there.

Cat-A-Tonic,

I went to Bacon Sails in Annapolis. They have a lot of salvaged hardware and I found a Gibb tri-roller car that fits my track perfectly. So, for $39.00 I solved my problem. Now, I am looking for another tri-roller for the port side!
