Having just read through one of the other threads, I have realised that I need to replace the eye bolt at the bow. Can anyone advise me where I can get hold of the replacment part?
Also is it difficult to fit the the mod?
With regards to the shroud mod how can I tell if I need to replace the shroud fittings as well?
Just out of interest, have ther been any other mods that I should be aware of?
Many thanks

I will speak to the Technical committee seperatly regarding a list of ISO mods which in the light of recent correspondence require publicising... When I re-furbed ISO 593 for the Nationals I didn't have the new jib tack fitting so (knowing the boat was 11 years old)I strapped the eye bolt down using a length of D12, so still need to replace this. However I did have in my box two new shroud fittings. If you have the eye bolt type these will be quite old now and will need replacing (nothing lasts forever I'm afraid). The new (or maybe not so new now) style are machined from st.steel and have a larger thread size(6mm as opose to 4mm.. or maybe 8 instead of 6, can't remember)The deck needs drilling to accept the larger bolts.. I assume Topper/Wet 'n Windy can supply???? |

Talk to Andy Holmes and crew at www.wet-windy.co.uk - that's where I got mine. The Duralac is a bit expensive for the tiny amount you need so ask around your club / Bosun before buying. But do apply some - it's essential.
You can identify the ring bolts as they are just that - a chromed ring on each of the shrouds and jib. The newer stainless shroud bolts are larger diameter - 6 or 8mm I forget which - with two machined flats and a clevis pin hole. The jib fitting is a plate with two fat self tap screws and a bolt that goes through the space frame. The self tappers go through the space frame and into the nylon block fitted inside. Just be sure to put PVC tape over the screw heads to look after your kite - and check it regularly. Surpising how sharp a bit of tape gets under pressure in a blow.
Only other mods I'm aware of are the addition of a hatch in the transom post enabling you to change to the bolted on gudgeons - if you need to do it. 814 is still standard nylon block embedded which works fine with the occasional bit of TLC.
To go with the bolt on gudgeons - they are the same as the standard fit - goes a 5mm packing piece to allow the rudder stock to swing a little more freely in the boat park. Saves some of the pressure on the casting. Again - not on 814 yet as not seen the need to spend the time or money.
As far as I know - that's it. Mike, Pete and others may have some extra info which I'm sure they'll post below. |

Bob,
Thanks also for your advice.
I thought I would do a bit of surfing at lunchtime to find the cheapest supplier of Duralac. I found one company that wanted £4.56 for 115 ml tube. The only catch was the £8.00 courier fee as they consider it a harmful product. I was also surprised that the cost of the new tack fitting came to over £20.00.
Oh well its a small price to pay to keep the mast pointing in the right direction
Cheers

Bob,
Many thanks for the offer. Couldn't make Sheppey at the weekend (even though I live just across the murky water)- too much going on with the kids!
Best regards

Shame - you missed a darned good event. Must be the best blasting this year - and I've said that before. Just gets better....
Crossing the waters to Garda ?? |

Unfortunately my wife has other plans.
But I am hoping to come along to the inlands at Datchet (provided that my crew can earn enough points for a weekend pass!)
Cheers

....And there was me thinking that it would be a doddle to fit the bow mod!
I have now managed to get a new Jib tack fitting from Topper (won't comment on what I thought of their service). I had a look at the pictures of the fitting attached to the space frame (Tweaks section Spini chute tying). The fitting that they have supplied me looks too flat. When I laid the fitting in place, the hole where the jib is attached looks too far aft (about 15mm). Which means that if I move the fitting forward, it will have to be bent round the front bar of the space frame? does this sound right?
If not, is there any measurement that I can use to make sure that the jib tack is exactly in the right place?
I guess the jib tack has to be in exactly the right place to comply with the class rules?
Would be grateful of any advice
Many thanks
