A 5000kg crane scale. Now we can test our rigging by measuring both the input (the tension we apply to the end of the lashing) and the output (how much tension is in the actual shroud or chainplate loop).
But I hadn’t realised that a 5000kg scale would be so much larger than the 1000kg scale we have used so far!
I haven’t been posting much here as I’ve mostly been working on our YouTube channel, however, I thought I would show some pictures of the new mizzen mast foot support work.
I am also adding some fibreglass tape to increase strength where we have cut away the starboard bulkhead to provide access to our “pullman” style double bed.
While doing this work in the aft cabin we have also finished (at last) the chainplate backing plates in the aft cabin. They were the first we did and we over complicated things with a full length plywood backing plate, plus a shorter plywood backing plate for the 3 shroud attachment points. Anyway the FR4 plates have been added and so that part of epoxy work in the aft cabin has been completed.
We have also been working in the lazarette on supports for the solar panel frames. As part of that work we found and fixed a void in the stern at the hull/deck joint and the damage caused by the davits that had been fitted without backing plates.
Now back to the video editing that will show all this.
Our latest video has been getting some really helpful comments on YouTube as well as directly. It has also helped us to reach a new milestone 🙂
It definitely seems worth exploring more. Particularly to consider some of practicalities that people have raised including:
Is the sheer strength of the Stainless Steel bolts sufficient? Potentially, the load on the bolt could be reduced by attaching the plates for the dyneema eyes with epoxy. Or they could be replaced by carbon fibre tubes epoxied into place.
Is dirt going to get in the dyneema and damage it? Could the solid shield protecting from chafe also stop water washing dirt in? Would a soft sleeve such as we plan for our chainplate loops help?
Will the water flow damage the Dyneema? Much the same issue as with dirt above.
Might there be resonance issues with the lashing (apparently might be more of a problem with more loops of thinner lashing).
Will the wider stance affect sheeting angles? Depends very much on the rig. It might allow a cutter rig to be sheeted inside the shrouds.
Should we use a standard thimble or low friction ring, potentially with a solid infill to avoid a point load from the bolt? We were trying to avoid metal in the water and keep the cost down but this might well be a good solution.
More thinking about whether to have a separate cover to keep the dyneema on and to provide chafe protection, possibly so that the cover can be removed without affecting the chafe protection for inspection or replacement.
We are planning a similar design for attaching a Jordan Series Drogue (JSD), potentially better than our previous idea.
Anyway, thank for the support on YouTube, it is encouraging and YouTube responds by sharing the videos more.
We arrived yesterday evening and are here for a couple of nights. It is very cold! Snow in Manchester before we came, snow visible on the Snowdonia range. So, too cold to do any epoxy work. Fortunately, the two panel heaters and two fan heaters can keep the cabin nice and warm.
Instead of working on the starboard backing plates for our main mast dyneema chainplates , we have recorded video footage describing our latest idea for external dyneema chainplates. Could be a great option for lots of older boats who are switching to dyneema rigging and want to avoid expensive fittings or who are concerned about their metal chainplates.
We also recorded progress on redesigning the bilge under our saloon for battery storage, water tank and for the first time some thinking about lightening protection. That involved taking the main companionway steps down, wasn’t as bad as I feared. We now have our batteries stored much better in approximately the right place.
We have also done some more detailed planning for the galley stowage and space for the fridge.
The weather is expected to be wet, windy and cold in the morning so we have some jobs planning work on everything in the motor room.
Coming up next week will be big news about our transport for getting to and from the boatyard.
