cable laid vs rope (left vs right twist)
Jim Lad replied to davec's topic in Masting, rigging and sails
Dave, I'm not sure just how large a hawser laid rope can be - when I was at sea we used to use 10 inch mooring lines that were hawser laid (just don't be in the way if one breaks under strain). Cable laid rope was indeed made by laying up three hawser laid ropes, which is why it was laid up left handed. The lower stays and shrouds of hemp rigged vessels were commonly (but not universally) of cable laid rope, and so left handed. On small ships the lower rigging was sometimes hawser laid. I'm speaking here of English 19th century practice, by the way. John -

I would imagine that kit builders supply POB hulls because thay're easier to cut and pack and customers don't need so much in the way of heavy tools or workshops to build large hulls. It would also be easier to incorporate lower gun decks or false guns into a POB structure. For the scratch builder with access to standard woodworking tools and some workshop space, I think that a solid hull (or bread and butter) would be a more practical solution than POB. John

Here are two illustrations from 'Seamanship in the Age of Sail' by John Harland that explain the operation of launching a boat from the deck of a sailing ship. This is an excellent reference book for those members who build models of wooden sailing ships and wish to understand more of their methods of operation and handling. John

Man, you really have parred your operation down to the bare bones, Popeye, but your crew need more backbone - they're gutless - I wouldn't rib you about that! John

No good, Mark - those critters are short about 50% of the regulation number of legs. Augie - I hope the can of coke wasn't open. That stuff could cause serious damage if it splashed in your finishes. John PS. If you need to buy the fish, make sure that they're really fresh and put a tiny hole near the mouth to show where the hook was.

Bruce, I'd think that the forward cormer of the canannel would be a good place for the bumpkin and, yes, just long enought to spread the sail would be right for length. As for belaying points for the guys and martingale, I think the only answer is that they "be secured at a convenient point". Ain't that the truth!! It's one of the joys of building ships of this preriod, though! John

And I suppose we'll eventually see a coffee pot and some mugs on top of those drawers, Tom. John- 326 replies

Very professional looking job, Piet. John

2.5 mm would certainly be a lot closer, and easier to work with around the curves of the hull. John

This is really going to be a fun one to follow, Mario! John

Yes, Druxey, but I thought it might still be a starting point for the heel of a swinging bumpkin. John

Just catching up with what you're doing, Tim - she's coming along really nicely. Oh, and by the way, congratulations to your daughter! John

Frankie, I think there's something wrong with your link, as it comes up as 'page cannot be found' on my computer, however your clue to the site's existance led me to it and to the article to which Bruce originally referred, so thanks very much for that. The relevant part of the long contemporary description of the ship states, "She has bumkins for the four tacks, and swinging bumpkins for the clews of the mainsail, to spread the sail when going free in light winds. Her lower studding sails are triangular, consequently she has no swinging booms" Bruce, From that megre description I think I'd be inclined to fit the bumpkins, as you suggested, at the fore end of the main channels. The photo below is from a prior period, - the frigate Trincomalee of 1817 - and of a swinging boom - but it may be useful to you in showing one method of attaching the heel to the channel. John

Sherry, His real secret is that the Admiral and the dog also sectretly help with the model making! John

Looking forward to seeing your serving machine, Andy! Hmm, the weather must be odd; it's pretty cold over here too - oh, yeah, it's autumn, isn't it? John

Hello Jakob, and a very warm welcome to the forum from 'Down Under'. One of your problems may be that your planks are too wide for your scale. For true to scale plank widths, your planks should only be about 1.5 mm wide at as scale of 1:200. Have you read any of the articles on planking in the articles/downloads section? there are several articles on planking to choose from. You can find them here: http://modelshipworldforum.com/ship-model-framing-and-planking-articles.php John

She's looking very neat and tidy, Popeye, as befits a top class yacht. Good on yer, mate - nearly there! John
-
Aha! That's interesting information, Bruce. If she traingular lower studding sails, then the bumpkins roughly where the lower booms would usually be would work well. John
-
Delightful work, Danny! John
-
Bruce, I've been having a look at Kipping, Biddlecombe and Lever and none of them mention your boom (that's easier to write than bumpkin)! I've also had another random thought. If the booms were where they would presumably have had most effect in spreading the mainsail when running free, then where were the lower studding sail booms? They should have been in the same area - if she carried them. John
-
Frankie, Please don't misunderstand me. I'm not trying to say that you're wrong or to put you down. The information that you've provided on Bruce's thread is quite correct, but the source that he's found is talking about a bumpkin being used in a very different way to what we're used to, and is of an earlier period than Underhill's particular area of expertise. I find that the mid 1800's is a bit of a 'black hole' with regards to rigging as it was a time of very rapid development in rigging practice and is not nearly as well documented as the periods before and after. I think it would be really helpful to Bruce if you could use your expertise to help us to understand this apparently particular and unusual use of a bumpkin to spread the foot of a sail when running free. I, for one, have never heard of this use before. Do you know of any other examples? John

Andy, I remember many moons ago our chief engineer sailing past our anchored ship in his dinghy, shaking his fist at us and yelling, "Those newfangled stink boats will never catch on." Strange people, engineers! John

Lovely as usual, mate! John
