I had a quick look at the above mentioned and they look like they are only sheaves. I'm looking for blocks.

Can anyone tell me where I can get a single sheave block that will run an 8mm 7x19 stainless steel wire through it. I have seen a barton block that takes a 5mm wire, but that is the largest I can find. It is for the junction between a single backstay and the joining running split backstay. Thanks

Thanks everyone for your input. I've taken all your advice onboard. Hopefully I won't be posting a horror story later on.

It is continuous rigging and the mast is quite chunky. It is a cruising yacht not a racing yacht with a masthead rig.

I mentioned in my opening post that I don't think that would work because of the narrow angle, and the temporary shroud running directly to deck - not over the end of the spreader. How do you run the halyard over the end of the spreader so that it will be doing exactly the same job as the shroud...

It's not on my yacht

Has anybody replaced cap shrouds, one at a time, whilst the mast is still stepped. I,ve got no problems changing lower shrouds, forestays and backstays one at a time, with a temporary stay rigged as a replacement, because the angles are large so the mast won't go anywhere. But when it comes to...

Thanks very much for everyone's input, especially Cliff and boatmike. Your two answers were exactly what I was looking for. Spot on. Cheers.

Hi David Thanks for replying. I think you will find that 304/316 stainless steel is at one end of the galvanic scale and aluminium is at the opposite end of the scale. Also monel is a very hard material, which is right beside 300 series stainless steel on the galvanic scale.

why is it reccomended to use monel rivets to attach stainless steel fittings to aluminium masts, as opposed to stainless steel rivets. Monel and 300 series stainless steel are right next to each other on the galvanic scale so it shouldn't make any difference regarding the corrosion factor. And...

Try www.sw-marine.co.uk They are a new yacht and boat rigging company based in Swansea. They have just started up in Jan.06, and have the roll and press swaging machines for yacht shrouds and wires.

Thanks Alan. I'm going to have to put my maths head on now, and dig out my old school books. Nightmare!!!! All the best.

Thanks for the answers I can find out the tensions in the split backstay bridle because I can reach them with the tension gauge. What would be the formula then for calculating the tension in the 'out of reach' upper bacckstay

Hi Can anybody tell me the answer to two questions. 1 How do you measure and set the tension in a split backstay. I know the tension in the backstay should be 15% - 20% of the wires breaking strength. But at the position where the single backstay splits into two bridle legs, it is about 12...
