Rig Fittings – How to Make Some of Your Own!!

Leave a reply

Most of us will have rig eyes, deck eyes, hooks, rings, loops, prodders and clips on our boats. One of my own favourites is this gorgeous sheet hook in the photo above.

I’ve always wondered if I should carry a little stock of such things in my toolbox for the day something goes wrong. That is assuming you can find anyone who sells exactly the right hook in sensible minimum quantities.

What about making your own? One always has to wonder what incredible expensive tools you would need. Well, in this case try typing “jewellery pliers” into Amazon and see what comes up. Really not expensive at all !!

You can see that this pliers will allow you to bend three pre-determined sizes of curve into your wire. It’s about £12 on Amazon.

If you want more variable size curve-making ability, this red handled one was about £8.

In both cases, you’ll want a good pair of snippers and regular pliers (to hold the wire as you bend it).

So where do you get the stainless steel wire?? Our friends at SailsEtc sell stainless wire in different diameters and, I think, in about 30cm straight lengths. If you want to do this, I suggest get several lengths of each chosen diameter in one order – just to make sense of post and packing costs.

Good to share something like this between a buddy or two, or just make sure that one or two people in the Club fleet have the kit to make what the fleet needs.

Classic Beginner’s Problem – “My Prodder Has Fallen Off!”

Leave a reply

Got a swing rig?

You’ll know what I mean by “prodder”. It’s a little bar which is there to help the forestay stand off and clear of the other gubbins at the top of the forward triangle.

If you say, “it cannot come off” or “you cannot lose it” I entirely agree. But when you’re a beginner, all sorts of mad things can…. just happen. Anyway, I’ve no idea how it came off, but it did. Obviously something I did but I just cannot imagine it.

Can you see? A stainless steel tube should locate on that simple hole in the mast. I tried to stuff the prodder back into that hole for a minute or two, but it was obviously the wrong idea.

What do other people do? Well it seems that Sailsetc have some clever little brackets that are ideal when you are building the rig – just slide them over the tube.

Not bad actually. I like fixings I can see and understand. Sailsetc say though that if the rig is already built, you may need to split the fitting and squeeze it over the mast tube. I was less keen on that. Apparently some people also form a cord loop at the end of the prodder and tie it around the mast. I can understand that too.

I instead gave the problem to the clever chaps at K7Yachts. In no time, I could see the answer. A hand made stainless hook, made from 0.6mm wire, that you wiggle into that hole. It need a little kink in the end to grip the inside of the mast tube. The rest of the wire rod sticks out of the hole, and it is cut off at about 2cms length. Then simply slide the prodder over that. Voila!! (see below)

There seems t one a choice of whether the prodder is perpendicular to the mast or the forestay. (I’ve no idea how to work that out!)

Anyway – really impressive fix. Light weight, clean windage etc

Rig Tension – What Does That Mean in Radio Sailing?

Leave a reply

When we all decide to come to radio sailing, one of the first things that grabs our onshore attention is people staring down masts with their knowing one-eyed look, tweaking stays with their sturdy race tuned fingers … and making clever approving noises. It’s great !

The curve of the mast is an interesting topic in itself. If you search Youtube for IOM videos you’ll hear experts looking for anything between “dead straight mast” to “a bit of prebend”.

Baffling, but fear not!!

On Nigel Barrow’s excellent website, he recommends a rig tension gauge by John Gill. It looks like this…

The sharp-eyed amongst you will notice John’s email address on the gauge if you want to contact him to get one. It’s a lovely carbon fibre thing – I just love it. Anyway, as Nigel points out, if you want to demystify your rig, get one of these.

If you are a keelboat sailor in your past, you’ll immediately recognise the basic idea. If you’ve had a Loos Gauge in your history, it is basically the same idea. I raced `Flying Fifteens for 25 years – the Loos Gauge is the central calibration measure for everything. I never went anywhere without mine. Honestly.

See those two big screws at the top of the gauge? You slide your shroud wire between those two (they stand proud) and the gauge gives you a way to understand rig tension versus deflection. Then you look up the gauge reading on a little chart, and if you know your wire diameter then you can read your tension in kgs.

We used to do the same in Flying Fifteens, but I soon lost the appetite to know tension in kgs … all you need to know is what the damn gauge number is.

If you look at John Gill’s photos above, you’ll see the way to use the gauge. (a bit blurred, sorry)

As Nigel Barrow points out, it’s quite a revelation to know precisely if your IOM shrouds are carrying the same tension, or you pop a new replacement shroud in and you want to get the tension matched again. Very good.

In 2024 I set myself two other goals:-

  • I want to get a feeling of also what backstay tension readouts correspond with apparently good performance
  • Now what about Marbleheads? No shrouds…. But actually rig tension is a very black art in the Marblehead, and there must be a way to shine some light into my darkness. I want to write separately about measuring jib swivel tension on a Marblehead – but give me time.

Calibrate, calibrate, repeat, repeat…. my New Year Resolution for 2024
