  1. Hi Tony. It's a long explanation but the shape of the hull is essentially derived from the stations. amidships and fore and aft are constructed from a few basics, floor harpin, breadth sweeps, floor sweeps, etc. Both the waterlines and buttock lines are a method of controlling the hull form largely at the bow and stern. There are no formulas or graphical means (like controlled sweeps) to develop these areas. They were largely at the whim of the designer. There is more than enough data above to reconstruct the hull form above. The waterlines and buttock lies can be extracted from the stations given. the bow and stern shape can be derived also. The buttock lines are shown beyond station 10 which is where they are most useful. in developing the waterlines and buttock lines they are played off against each other until the hull form is fair. In the construction of the lines below I also used what I refer to as control lines. these are developed somewhat at right angles to the waterlines. The hull form is plotted into this view and the shape smoothed out. The points then projected back into the body plan and sheer plan and the waterline/buttock adjusted as required. See also the pdf on understanding ships draughts. understanding ships draughts.pdf This playing off of the lines is repeated many times until the hull form is properly faired. The mid body is well controlled by the floor harpin, breadth sweeps, floor sweeps,rising line of the floors. Regards Allan
  2. Hi Guys. A couple of pics (before my attempts at defying gravity) Much better now. I will be starting the rigging soon. When I get bored drawing Investigator plans.
  3. Hi Guys. Here is the revised booklet with Fig 1 included. Regards Allan PLANKING_rD.pdf
  4. Hi bud. You are correct. Fig 1 is missing. I will fix it an upload a revised version. Stay tuned. Thanks for pointing it out. Kind regards Allan.
  5. Hi everyone. Not much model making ATM. Got over some health issues and then fell off the roof, broke my arm and fractured my back in 7 places. So it's left hand computer work for a while. This is what I have been doing. A set of rigging plans for Danmark. I got distracted into HMS Investigator. It is a drawing from first principles as very little is known about her dimensionally. Some other reconstructions are around but I have some short comings about them.
  6. I can only thickness up to 25mm. So 4 pcs 25 x 260 x 1 each colour. I am south of you. Could post them. Regards Allan
  7. Huon pine and close grain cedar. How wide do you need the planks. Regards Allan
  8. Hi Vic. That looks like a nice kit. Keep us posted with the build. Regards Allan
  9. Hi guys. I have been a bit quiet on this dealing with some health issues. (all good now). Here is a rigging schedule and belaying diagram for Danmark. All the numbers correspond to the Billings ones. Some of the rigging is NQR on the original plans. I will post doctored drawings of the errors soon.

  10. Hi Chris. No doubt the replica was built as necessary. The choice of timber has a lot to do with it. The method of terminating planks on the wale is typical of dutch vessels. The issue with most kits is the double planking technique. The outer layer is so thin that bending the planks sideways as is necessary is impossible. Even with single planks it is not possible without using steelers or drop strakes. Oak and Fir is a much more workable timbers than Jarrah and that is probably why the replica is planked as such. No problems. I was just pointing out that English ships of the era would have been planked as Kipping describes. I think that Karl almost had it right but in practice it would need more steelers/dropstrakes to achieve the desired result. Another interesting read is about ribbands. They used these to divide the planking into sections so they could work out where to put the steelers. Kind regards Allan
  11. It does not matter how you plank your model. Whatever you feel comfortable with. However the replica Endeavour is not planked in the manner in which it would have been done in Cook's era. All of the planks terminated in the rebet in the stemKIPPING_PLANKING.pdf Here is an extract from Kipping which explains the process in detail. Allan Tyler
  12. The manner in which Karl depicted the bow planking is difficult to produce. It requires compound bending of the planks. The replica is planked below the wales in a fashion more akin to the methods used on Dutch vessels. Here are a couple of drawings I produced in the 90's based on the how I planked the model. It's not the same as Karl's but easy to achieve. Based on contemporary paintings and other work I think it is a good representation. Regards Allan
  13. One ought not state that a reference has errors without being specific. I does not help the model builder. Please point out any specific errors or where you may disagree with the work. Regards Allan Tyler
