We use the highest quality standing rigging components available, and we won . If it does not rotate, spray some WD40 but never twist the rod rigging. How to Measure Standing Rigging With the mast and rigging still standing and set to its normal sailing positions, tape or mark all the threads of the studs where they exit the turnbuckles. For example, many chainplates are too thin to grip clevis pins correctly. Check for anomaliesThe stud terminal on the end of the wire is normally right hand thread, while the bottom part connecting to the deck is normally left hand.We do occasionally come acrossa rig where the thread direction on the existing fittings is opposite to normal.Opposite rotation is an odd featurewhich sometimes occurs with metric thread on some French built mastse.g. Both SK90 and SK99 are heat stretched at the fiber level so that makes them a little more difficult to heat stretch completely at the braided line level. Since this boat is sailed in the Mediterranean we must have a good light wind setup and be able to intervene on the shape of the sail as the wind increases. We have had many customers who have found a great deal on a used boat only to discover that they need to spend a small fortune on new rigging. For a -inch turnbuckle with a -inch toggle, the chainplate should be at least inch thick. To bring everything back to zero tension, I went up to the first set of spreaders and loosened the D2s which I would then adjusted last. Wire rope is sized/priced by its diameter which . Jimmy Green Marine commonly supply 3 types of rigging screw for standing rigging.These are sometimes referred to as bottle screws or turnbuckles. I'm not sure that the distribution of the force on the sail, in force at the top and on the boom, is correct. So we had left-right and fore-aft problems. You understand that the calculator provided is for general sling length and size suggestions. Unstep the mast and remove the rigging from the boat. Remove any pins from your terminal ends before taking measurements. I hear about these guys on every forum everywhere. Measure your wireIt is important toestablish the diameter of your wire becauseall the different types of wire terminationare manufactured with specific dimensionsfor each diameter. The overall shroud load is divided up between your shrouds. For example, low stretch is very important in a halyard but not necessarily in a sheet. Continuous rigging is made up of single pieces of wire that run from the top of the rig to the deck allowing the tuning to be done at deck level. If they are not willing to take the financial risk, are you willing to risk yourself and your crew? there is no M11 size. https://www.ebay.ca/itm/5-13mm-HampiKl3MW1P7_hTkTw. If in doubt, get a professional opinion. As said, the backstay is simply not there, to make room for the square top mainsail. By now, I would say, even on cruising boats it is one of the most common rig arrangements. The original spec. T-terminals or shroud terminals often provide the most difficult decision.There are t-terminals on the market such as the Sta-lok and OS/BSI varieties which are sometimes referred to as universal.This means that they aredesigned to fit a variety of different backing plates, and they may well prove to be a useful resource if your existing terminals can't be replicated.However,it is bestto match the t-terminal to the mast backing plate from the same manufacturer.The thickness and width of the head,as well as the angle of the load bearing 'shoulders', are all critical factors in selecting the correct version. Required fields are marked *. Add splices, shackles, and whipping with a single click. chunkier appearance than forged parts because the internal grain of the material remains parallel, requiring some faces to be longer to retain strength. Therefore, with a strong breeze, we can intervened on the backstay to reduce the forestay sag and flatten the mainsail. When riggers cut rigging in the workshop they are very unlikely to make pairs of shrouds of different lengths. He asked Isnt the industry standard just a ploy by manufacturers to sell more wire. That said, on a nine-tenths rig it is unlikely that you could break the mast tip under spinnaker just because you did not set the runner. The line is also lighter and it doesn't absorb water, as compared to Vectran. Control Lines: Outhaul - Boom length x 2. We are not experts but just trying to show our thinking processes. But have you ever seen a boat so rigged? 20% is 576kg so if we size at the 10% we get 5760kg (we can simplify the calculation to looking for a Dyneema line that is at least twice the breaking limit of the stainless it replaces). Please read the instructions completely before you start measuring your rig. Elastic Stretch is much the same to work with as creep except that it will show up quite quickly, so a few re-tensions in the first few months should sort it. Ill add Dynice Dux back into the pricing and options. Heat stretched SK75 really performs better under a constant load. Jusben Engineers is a major B-BBEE engineering, construction, and maintenance contractor, delivering complex . Staying within elastic limits gives safety factors of 2.5, 2 and 1.9 respectively. If you need to replace a halyard, please dont pull it out of the mast. The mysteries of sizing Dyneema standing rigging. The spring-loaded ones suitable for adjusting the shrouds of a Mini 650 are useless. With the mast and rigging still standing and set to its normal sailing positions, tape or mark all the threads of the studs where they exit the turnbuckles. A UK Chartered Engineer and Fellow of the Institution of Mechanical Engineers he has, since 2001, managed the rigging engineering group at Bechtel. This will help to prevent metal fatigue. only hand tools are required for installation, can also be completely disassembled and reused (some models require inner cone replacement) providing great longevity, can be manufactured to very precise tolerances, the waste material can be recycled to create further parts. This yields a shroud load of 6,000 pounds. The rake depends on the relationship between the length of the forestay and the shrouds as a whole. Stainless steel isnot a malleable metal, so the pressure applied by the roller dies is exceptionally high, creating a solid bar of material. Can Galvanised Steel be used with Stainless Steel? This will help to prevent metal fatigue.Check the dimensions of the fixing points for your shouds and stays, traditionally known as Chain Plates: The picture below shows a swageless eye terminal (top), a Talurit eye (middle), and a swageeye terminal (bottom).Swageless terminals are characterised by a short overall length and a relatively wide body diameter.Taluritis the process ofpressing the wirein a soft copper ferrule.Swages are slim and relatively long overall. This system with T-bone on the checkstay give you maximum flexibility and is obviously suitable for those who know how to use it. Many of our do-it-yourself customers with continuous rigs order their rigging with a swaged terminal at the top of the mast and a Sta-Lok or Hi-Mod mechanical fitting for the bottom so they can fit the rigging on site. But I mean, why dont hey have prices listed on their site?! Swaged terminals are manufactured using 1 or more of the 4 processes listed above. Can you break it down for me? One of the most frequently asked questions we hear is: How do I measure my sailboat standing rigging? only available on wire up to 6mm diameter, because larger diameters are not flexible enough to turn around the tight radius of a thimble without detrimental deformation, the most economical method for professional wire termination, Ideal for fittingonto oversized pins andattachment points with the additionofa stainless steel thimble, can also be used to form a loop for masthead attachment. So, in order to avoid any dangers, we set the inner forestay (to double up with the forestay). rope), you will want to consider length, diameter, stretch/performance, material/construction and, of course, price. We highly recommend you hire a professional rigger if you are not familiar with this process. Your email address will not be published. Since you're doing lashings, an inch either way won't matter: what's more important is cutting all your lowers the same length so the deadeyes all line up and look symmetrical. For the moment I wanted to see the mast without no tension in the D2s. Taking the upper and a single lower of 5/16" gives a safety factor of 3.1. In addition to this it was clear that when the starboard runners and checkstay were tensioned, the mast deteriorated in shape. I was satisfied with the shape and only the sea trials could have confirmed the correct setting of the D2. With proper measurements (wire diameter, pin sizes, wire lengths), we can give you a very accurate price for the standing rigging itself, but there are often unforeseen complications during the job (bad spreaders, corroded mast bases, hardware that is stripped on the mast, frozen pins, chainplates that are failing, etc. Can you break it down for me? If you are replacing your turnbuckles, make sure the existing turnbuckles are adjusted to their normal set position for sailing before taking your measurements. We repeated the exercise for the low diagonals D1s.
