  1. Astounding model. Thank you for the renderings. May I ask what software is being used and, if not too personal, what are the specs on the computer employed? Wayne
  2. I look forward to your progress. It looks like an exciting project. One very small thing. The box shows two pins at the ends of the spokes set into the felloes. I don't believe these are at all right. There are no pins or fasteners in the wheel. Everything was held together by the iron tyre (rim). If you consult photographs you should see there are no such pins. I feel like I am being more dogmatic than I should, so I am open to correction and reproof. Thanks for letting us look over your shoulder while building. Wayne
  3. Goodwin and Lavery are entirely different books. Goodwin is the resource for building the ship. Lavery tells you what to put in it. Both books are necessary resources. Add to them Lees' book on Masting and Rigging and you will have a nice trilogy for building these ships. Wayne
  4. Beautiful work. One word of caution: the thin gasket material works well for the braces. But later on it is used to cover the luggage rack and to close in the storage space beneath the driver's seat. On my coach the thin gasket material has dried out over time resulting in annoying curls. By now it is too brittle to work back into place. It is not impossible but I would look for a different material to use when coming to that part of the build. If I can I'll edit in a photo later. Wayne
  5. Dan, when you first purchased your Stage Coach I followed suit. I even spent time on the Scale Horse Drawn Vehicle web site (which makes me enjoy this forum all the more). I have now built ME's Stage Coach, Conestoga, Doctor's Buggy and Chuck Wagon. The carriage works shown by Mike seems to be the common method of supporting all kinds of wagons. If I were to put a New England whale boat on wheels, that is the arrangement to be used. I posted a few videos on YouTube on building the Conestoga that can be found by searching for "Building the Conestoga Wagon." I append one photo just for fun. I love what you are doing on the Stage Coach. Wayne
  6. 18th century sailing commands

    "I've always hoped someone would design a square ringed ship simulator" http://www.pdavis.nl/ Is graphically crude, but the elements of handling a square rigger are there. It's old by now, but you can get a feel for how the various sails affect the movement and handling of the ship. Wayne
  7. William L. Crothers

    Yes, according to http://www.surnamedb.com/Surname/Crothers
  8. The boats on Lagoda have the oars, paddles, mast, sail, harpoons etc., and line tubs. This photo is not terribly clear, but indicates the contents. In that this model at half scale was built by men who had personal experience with whaling, I would give this arrangement serious weight. Wayne
  9. Joshua Humphreys' Notebook

    Addictive, indeed.
  10. Beautiful. You have modeled everything except the grease. Well done! Wayne
  11. I had a hard time knowing what I was looking at on the drawing of the beam. This link has a clearer drawing from an engineering book of 1891. https://books.google.com/books?id=LuIOAAAAYAAJ&pg=PA350&dq=walking+beam+steam+engines&hl=en&sa=X&ved=0ahUKEwiO1ZGxxb_PAhWBOT4KHaQAA7YQ6AEIIzAB#v=onepage&q=walking%20beam%20steam%20engines&f=false Scroll down to see your style of beam. This beam is of a truss design and is made in two pieces, the inner skeleton frame which is cast in one piece and the outer strap which is forged in one piece. At either end of the strap are the "journals" for receiving the piston and driving rods. The "journal" for the air pump is cast into the skeleton. The strap is held to the frame by "gudgeons." The illustration in the link above shows the skeleton is thicker in the center. I'm sure this is known to you, but it was a pleasant time for me to track this down, so I thought I would share it with others like me for whom this project is presenting an entirely new field of knowledge. Wayne
  12. I like your observation that the block and tackle would support the arm when pressure was below the relief setting. Could the block and tackle also raise and then secure the valve in an open position so as to blow off steam quickly? Perhaps in an emergency situation or if the boiler was being shut down? Is the outside ball smaller (lighter) than the inside ball? Perhaps this is the manner of making a fine adjustment to the valve, especially if the arm were calibrated on the opposite side. Again, great work on the 3D modeling. Rope can be something of a bear to make until you get the hang of it (no pun). Wayne
  13. I have little knowledge of this subject, but would the boiler also have two or three relief valves? This is inspiring work of a superior quality. Thanks for letting us peer over your digital shoulder. Wayne
  14. Since no one has offered anything, I attach below the waist detail for the frigate Euryalus. It shows modifications made to the waist for 1803 to an earlier plan. The note reads in part: "The Skid Beams, Flats of Qtrdeck, Forecastle & Gingerboards to be shifted into each other &c ..." This does not settle the issue for any other ship, but it is a piece of paper from 1803 that indicates an unbroken run of planking at the waist on a RN ship. I agree that it could be read differently, but this is my take. Wayne
  15. Photographs of the Victorian Victory show two fair leads in the same place outboard. For example, Wayne
