  1. If you are referring to the Vancouver expedition, Discovery was as depicted here (From the RMG collection). She was similar to a naval sixth rate, but with a merchant ship body. (The cross-section would have been fuller and the bow much bluffer.) If you aren't too fussy, I suppose a kit of Fly, a Swan class ship might be adapted to resemble her. (For those interested, the drawing shows ventilation scuttles on the lower deck: a detail usually omitted from official draughts.)
  2. Re- re- re-working? Sounds familiar! Instances of down-stream impact: positions of timberheads, placement of scuppers, positions of chain bolts....
  3. I suspect this is better planned out ahead, Alan. At least, that's been my experience. The moment you change one element it impacts many others, a kind of domino effect!
  4. That information is much more helpful! Illustrated below is very much like what her appearance would have been. The plan shows a slightly later and larger ship, after conversion in the navy. Take away all those gun ports and the barricades along the upper deck, replacing them with open rails, and you will have a pretty good idea of what your Princess Royal looked like. (This drawing is from the Royal Museums Greenwich collection, reproduced under the Creative Commons licence.)
  5. Alan: you need to study contemporary 'disposition of frame' draughts. You will see that toptimbers are either 'shifted' or 'cast' to form the edges of the ports. Cutting into the toptimbers to frame the ports was not allowed, as it would weaken the structure.
  6. Meade, Mark? More likely Porter, Stout, Sack or Gin. Of course, many contemporary models were not shown with armament. I think we can guess why!
  7. Hi, Wayne. I was actually given a copy of this Occasional Publication No. 6 last month by a fellow modelmaker. He was dispersing the contents of a deceased model maker's workshop and knew I had an interest in "that early stuff". I'd never come across a copy before and was working my way through the text yesterday.
  8. I see that no-one has replied to your query in over a month, Holleia. The probable reason is that these weekly publication models were begun by many, but most (if not all) subscribers dropped out after a short while. I doubt if anyone lasted the whole 100 weeks and, if they did, they probably wanted to keep the completed model.
  9. All of which means it's nice to build a 16 gun vessel! Nice work with the duplicator, Mark. I agree that 'tuning' everything during set-up is the secret.
  10. A little more information would be helpful. Have you any idea of her size or tonnage, for instance?
  11. This comes a little late to the table, but I have just come cross a description in A Treatise of Shipbuilding, circa 1620-25, as reprinted, edited and annotated by W. Salisbury and R.C. Anderson (Society for Nautical Research Occasional Publications No. 6, London 1958). It reads as follows (pages 26-27): The next thing to be drawn in this plane of length and depth is the swimming line, which is a principal thing to be regarded for the good qualities of the ship. From that line are set off the decks and ports for the ordnance, higher or lower as we will have them lie to pass; therefore of right there should be marks made on the ship's side to direct the mariner always to keep her in that trim, neither to sink her deeper nor let her swim shoaler. The depth of this line is taken off the midship bend, for where the two upper sweeps intersect each other with respect to the thickness of the plank (which intersection is easily found by drawing a straight line through the centres of the upper sweep and futtock sweep), from thence to the ground line is the true depth of the swimming line. Which depth being marked upon the midship line and upon each perpendicular of the upper rising, draw a straight line from stem to stern. So you have the swimming line desired.
  12. Yes, those timbers are very vulnerable to damage. Like Greg, I've also experienced the snapping sound that one doesn't want to hear!
  13. This thread seems to have generated a lot of interest and comment. Let me see if I've got it right: Kit - built straight out of a box using the manufacturer's instructions (if you can understand them!) Modified kit - as above, but with additional details that have been purchased, such as photo-etched sheets, rope or blocks. Kit-bashed - one or more kits that have been cobbled together to represent a different subject than the kit(s) Semi-scratch - from based on a kit, but heavily modified using parts made by the builder, to builder fabricated with some commercial parts Scratch - completely fabricated from raw materials by the builder, no commercial parts Museum quality - an over-used and hence now meaningless term (Yeah, I'm sticking my neck out on this one!) The 'semi-scratch' definition seems to be the broadest, if my summary is correct. Should there be sub-sets in this category?
  14. I'm not that familiar with the physics involved, Hellmut, but the frictional forces in a sheave will surely vary. The factors to be considered are: 1) friction between the sheave and its pin 2) the angle at which the line enters and leaves the sheave (i.e. how much contact surface there is between them) 3) the diameter of the line and the groove in the sheave (surface area of contact) 4) the coefficient of friction between the two elements 5) diameter of the sheave There maybe other factors that I've overlooked. Of course, multiple sheaves will complicate things even more.... Perhaps this can all be reduced to a vector diagram. Mit grusse
  15. Thanks so much for sharing these photos of your expedition to Chatham, Tony. The folk there are great if they know you are a serious student.
  16. Tyes had blocks at their far ends attached to tackle. The tackles could be let out, this lowering the yard, or hauled to raise it. Are you confusing these with jeers?
  17. If it's a figurehead you're after, Jerry, see the Admiralty Models web site....
  18. Definitely rougher at .1mm than .05mm. Thanks for showing us comparative results.
  19. Flow charts, feedback mechanisms and basic electrical circuitry I do understand, or I wouldn't have a clue about what you've presented, Hellmut! Thanks for this primer.
