    Steel is a good source and another of course is James Lees Masting and Rigging which is more detailed and covers from 1625-1860 as there were many changes over the years.  Many consider it the most complete single book on masting and rigging for English ships.

    Allan

    I have him too and I refer to him regularly. The problem is he doesn't often explicitly address cutters and so I have to take the principles and apply them rather than wholesale copying.

     

    Basically my order of preference is:

    1. Steele
    2. Lees (If he addresses it)
    3. Goodwin (if not in conflict with common sense or the above)
    4. My gut / what I think looks the nicest

    I've encountered this as well with all my epoxy pours.  For me, it's usually inside the bottle so it's not a problem because it's hard to distinguish raised edges from distortion looking thru the glass.  However, when I did my base for Archimedes' Claw, the epoxy noticeably leeched upward into the rocks at the base of my seawall wall.  I do not believe the center of the epoxy shrank during curing because I know what level I poured and the edges ended up higher than my original pour.  The edges seem to crawl upward during curing as they are in contact with another surface.  There's probably some chemistry or physics behind that, but it's well beyond my expertise.  Perhaps @Roger Pellett could weigh in on this phenomena.       

    This will happen with any epoxy pour. The issue is the epoxy is adhesive (it sticks to other things more than itself). So it has a tendency to try and creep up the sides due to a combination of the adhesive nature and the surface tension (it creeps a bit and then the surface tension pulls more up so it creeps more etc...) This is counterbalanced by gravity, but if it has lots of things to "grab" then it can climb very high. This a particularly pronounced problem if you have a small crack. I have had it creep up a thin gap so it was way above the rest of the pour and had to hide it with paint etc...

     

    You can try to solve this by:

    1. Designing around this (making sure there are no thin cracks it can creep up, leaving space so you can cut off the edges etc...)
    2. Putting your sides only to the height you want to pour to. This allows you to fill all the way to the top and the surface tension will hold it level.
    3. Pouring in multiple thin layers (still doesn't perfectly solve the issue)
    4. Sanding down and polishing the raised edges. Note: I have never tried this on something that I wanted to be perfectly clear like water, I have mostly used epoxy for ice and so I can just cover those bits with snow and make it looked scratched etc and it doesn't matter.

     

    EDIT: I can illustrate this by showing you some pictures of a figure I did a ice pour for. The picture below shows the figure before the pour. You can see how I have a lip I want to come up to.

    Then below you can see after the pour. I don't have a picture before I added ice, but you can see how the resin is level around the edge. However, under the rock, the reason there is so much snow there is because it crept up the bottom and I had to hide it with snow.

    In the following picture you can sort of see where it has crept up most of the back of the hand.

    I realize this is being really picky for some and no reflection on your work, which is awesome, but why do the plans show cable laid rope for the stays on the  drawing in post #365, but then shroud laid in the drawing in post #367?   Cable laid was the more common for the stays while shroud laid rope was the more common,  but not always the case, for the shrouds.  Again, nothing to do with the quality of your build which is exceptional.   

    Allan

    That is a question you would have to ask Goodwin :).

     

    In general I would say that there are a number of errors / inconsistencies I have found in the drawings for the Alert book (for an example of this see post 365 where I discuss the problem of the foresail halliard). As I note in post 367 there is also the problem that the preventer stay in that diagram is attached with an obviously thinner rope which makes no sense as there is a single failure point. 

     

    My practice has been as much as possible to ignore the drawings for the purposes of determining the rope type and size and just go with the steele table for the ropes (Goodwin includes it in the book). In cases where the table is not clear (e.g. naming conventions are deafferent or a line is missing), I have tried to use common sense and refer to the drawings.

     

    So in my case I used cable for the stays and the shrouds as that is what the Steele table called for. The running backstays I used shroud laid as my best guess as to which was the correct rope in the table was shroud laid.

    Well done, quite the paint collection you have there. 

    I have accumulated a few over the years. Some get used more than others. I just buy them as I have a use for them and over the years you accumulate a lot as apart from a few colours I rarely run out as I use them in such small amounts.

    Also the top shelf is made up of every additive under the sun which tend to come in large bottles and I use them by the drop:).

    Well done. That is great work with the PE. The model gets much bigger now the bowsprit is attached so be careful turning it around in a small workspace !🙂

    Yes it is surprisingly big now. Part of the reason I originally was trying to delay attaching the bowsprit was for that very reason. But given all the trouble I had with the bowsprit it is probably the way to go. I am to the point in the build where no matter what I do I am going to have restricted access.

     

    I try to keep it towards the back of the desk but yes I am a bit worried I will catch it at some point.

  6. Log #64: The Bowsprit

    As I discussed in my last post, I decided that I needed to do the bowsprit next before I proceeded with any more rigging. As you will see this is another lesson in “it would have been much easier if I had planned ahead”.

     

    First step was to make the bowsprit itself. This was done in the same manner as the other spars with my drill.

    PXL_20231117_151956459_Original.thumb.jpeg.ec15224fd834752c20d10af54234124a.jpeg

    I decided to paint the end red as I liked the look of that better than the black suggested by the kit. This was done in a similar manner to previous painting. I highlighted the sides towards the bottom, the top I left largely one bright colour with some less pronounced highlights towards the inboard end and the edges. You can see a progress picture below after I had blocked in the main highlights before I started glazing to smooth the transitions.

    I also decided to rework a lot of the ironwork as in many cases the kit version didn’t really match Goodwin and also at times looked a bit flimsy. These were made using scrap from the kit PE. The eyebolts you see below that were attached to the rings were the ringbolts from the kit PE with the attaching point not cut off so I could insert them into a hole.

    PXL_20231118_154829292_Original.thumb.jpeg.ad960ba5b2d27dc6e89d49d8905f0cb6.jpeg

    For securing the bowsprit I scratch built using the edges of the thicker PE sheet from the kit. You can see it below compared to the kit version.

    After blackening you can see the result. I also drilled a simulated sheeve into the end of the bowsprit as per the Goodwin arrangement.

    For securing the bowsprit I first attached the plate.

    PXL_20231124_010353529_Original.thumb.jpeg.c7627fe5698579d9fdb2903c78917e6e.jpeg

    And then I attached the rest. Notice all the damaged belaying pins. The whole process of drilling the holes for the iron bars to secure the bowsprit was fraught with problems. At one point I completely broke the whole assembly and had to reattach everything and in many cases add some paint touches to hide the damage. It would have been much easier if I had planned for all this from the beginning. In the picture you can see me gluing the ring to the plate. I have a clamp holding the laniards away as I don’t want to get glue on them accidentally.

    To me it looks, as if the boom runs in at deck level. It then could be secured on deck with wooden cleats and a stopper block at the inner end.

    Ya I was thinking something along those lines, but I was wondering if anyone had any definitive answers as to what the practice was.

     

    I have been considering rigging the mizzen on alert, just as something a bit different.

    I must be v careful of what I commit myself to but I’d be more than happy to pull some specific records for you next time I have a slot scheduled in the archives’ reading room or map room.
     

    Unfortunately I probably now have all the info I need for the time being wrt HMS Diana but I imagine I might need to return there in future to get my sails built accurately (sails/masts/yards).
     

    Give me a (short) shopping list of specifics and I’ll take some pics. Would save you the air fare! I might even consider a special journey if I’m at a loose end as it’s a lot of fun to pull the records of something nobody has seen for centuries (although the trains have been very professionally and reliably stuffed up every time). I tend to heal my travel tension with a decent pint while mulling over the photos when I get back to my local pub.

    That is very kind of you, I will definitely send you a short list (I just have to whittle it down first :))

  9. Log #63: Rigging the Preventer Stay

    Thank you to everyone who has stopped by and commented and given encouragement.

     

    With the Mainstay done, I moved on to looking at the Preventer Stay. Here there is even more variety than with the Mainstay.

     

    Goodwin depicts Alert with two closed hearts. The odd thing about his depiction of this arrangement is that the line connecting the heart to the stem is thinner than the preventer stay. This does not make a lot of sense to me as it is a single line and so why have a heavier line at other parts when the thinner one will be the weak point.

    IMG_0342.thumb.jpeg.79251d8a092ba92ccd561bcb2619f7f5.jpeg

    The Hawk model simply depicts the preventer stay attaching to the stem using a single thimble.

    IMG_0344.thumb.jpeg.2b4652b4d5b6fcacdb88e8dacdf775a0.jpeg

    The science museum model shows the preventer stay below the mainstay or possibly this is another line and there is no preventer stay.

    IMG_0343.thumb.jpeg.a2938a2683e06ec16bd3f9a553d20d47.jpeg

    The kit goes with two thimble sized together and Chuck’s Cheerful has no preventer stay.

     

    When it comes to other builds on MSW, most have gone with the kit arrangement, but Blue Ensign decided to go with the Goodwin arrangement using the closed hearts. This latter arrangement consistent with Goodwin is what I decided to go with in the end. In this case I don’t really have a good reason for picking this over the others apart from I liked the look of it the best.

    PXL_20231117_040034468_Original.thumb.jpeg.3d93a76e24c65afad7db05f5f808ab38.jpeg

    The one change from Goodwin I made as to use the same 0.8mm cable for the section attached to the stem as I felt this made more logical sense than using a lighter line. If I was being strictly correct I should probably have had a metal bit inside the served loop that attaches to the stem. However, I felt it wouldn’t really be visible and so I just stuck with serving the area.

     

    I also made a small adjustment to the masthead as I was having problems with the stays slipping down. I added an eyebolt just above the last of the pendants to keep the stay from slipping down the mast. Even if not strictly correct it is barely noticable.

    PXL_20231117_042343393_Original.thumb.jpeg.31f6e7e4ca9ebad8bcc62a7faa6528ea.jpeg

    And with that the main standing rigging is done. In my previous log I mentioned that I was planning on next adjusting the tension on all the lines, but looking at a few other logs and thinking some more I think that I first need to get the bowsprit on the model. This may just be me trying to procrastinate on the ratlines :), but as much as I have enjoyed the rigging, it is very fiddly work and I like the idea of doing a slightly different type of task for a bit.

     

    Thanks for stopping by and here is a shot of the current status of things.
