  1. Hi Everyone.. I'd like to wish you all a very Merry Christmas and a healthy and Happy New Year. There's been no progress on Kathryn since September, due to the serious issues we've been dealing with. However, all of the daily doctor visits and treatments have come to an end and we're starting to get back to our normal happy lives again. I'm hoping to get back to Kathryn's rigging in the near future. In the meantime, thanks again for all of the wonderful comments on the build, and I'm looking forward to being active on MSW again. Best regards to all!
  2. Hi Patrick - just catching up after being 'gone' for a while. Really nice progress.
  3. I agree about the micromotor. I have a Marathon model - fairly expensive but I used it for years when I was bird-carving and it has been really valuable in the ship modeling. Any micromotor should have a foot pedal for optimum control. Less expensive micromotor options are available on eBay, but I don't know anything about their durability. https://www.ebay.com/itm/New-Dental-Lab-Marathon-Electric-Micromotor-Polishing-Unit-N3-35K-RPM-Handpiece/380881901575?hash=item58ae549807:g:qxgAAOSw5FpZmpTq:rk:2:pf:0
  4. Welcome back Brian. I'll be following as time and circumstances permit.
  5. Hi Patrick Just checking in after a prolonged absence and very impressed with the progress on Genesis. Bravo!
  6. UPDATE Hi Everyone. I'm sorry that it's been quite a while since my last post. We've had some serious issues at home lately, and my focus has been there rather than modeling. These issues will continue for the foreseeable future, so I'm not sure how much modeling time (or focus) I'll have. If I do make some progress on Kathryn I'll continue to post updates. Thanks everyone for all of your 'Likes' and comments through the build - they have meant a lot to me.
  7. Glad to see you start this, Kurt. I'll definitely be a follower.
  8. Hmm - that's interesting, Ron. I looked back at all of the photos I have of Kathryn and didn't find any furled sails that look like that. Here's a photo that was taken during the HAER survey during the 1990's: Here are a couple I took in 2015, right after her rebuild: And here are a couple I took in 2017 during my last visit to Kathryn: Also, I took a quick look through the book "Working Skipjacks of Deal Island" - all of the skipjacks shown in the hundreds of photos are operating under power from the yawl boats, so they all had furled sails (or no sails in one instance) and none showed the arrangement you're referring to. So, I'll be leaving things the way they are. Thanks.
  9. Kurt - thanks for your kind words. Both hobbies - ship modeling and bird carving - have their own unique challenges and have been very satisfying for me. I'm still learning and don't consider myself a 'master' by any stretch of the imagination, but I'm enjoying the whole experience. Druxey - thanks! Your sail-making supplement answered a lot of questions for me - without it I don't think I would have attempted to put sails on Kathryn.
  10. Part 82 –Mainsail cont’d After creating Kathryn’s main sail, it was easier to install the mast hoops on the sail before bending the sail to the mast. Kathryn’s lower mast hoops are attached to the sail using a jackline that runs through the lower grommets, allowing the mast hoops to move up and down with some flexibility. The upper mast hoops are seized directly to the sail. Since the sail will be furled, I decided to seize all of the mast hoops directly to the sail using some light thread. The first action was to secure the mast hoop by running a loop around the hoop and running the loose ends through the loop. The loop and loose ends were pulled tight and then were held using a couple of third hands, and the line was fixed in place using some matte medium. After the knot was set and with the mast hoop held perpendicular to the sail, the two loose ends were run through the sail from either side. The two lines were tied in a knot below the mast hoop. And then the loose ends were brought above the hoop and tied again. The process was repeated, tying knots below and above the hoop at least once more, and then the knots were painted with matte medium to secure them. After the medium had set, the loose ends were trimmed. After all of the hoops were attached, the lower double block for the main halyard was seized to the head of the sail. Finally, lines for securing the lower corners of the sail were seized to the tack and clew. The mainsail is now ready for installation on the model, which will be covered in the next post. Cheers everyone!
  11. Part 81 –Mainsail Kathryn’s sails will be furled, so I decided to use silkspan for the sails to reduce the bulk of the sails. David Antscherl offers a very good process for using silkspan in his Swan IV Sail Making Supplement, and I used some of his suggestions in making the mainsail. I found a good source of silkspan – Brodak Control Line Flying. They offer a medium weight and a lite weight version, and both come in packages containing 2 24” x 36” sheets. http://brodak.com/catalogsearch/result/?q=silkspan&x=0&y=0 The first step was to build a frame that would hold a large piece of silkspan. I mounted the silkspan to the frame using chart tape, and then held the frame vertically in an old artists easel. Following David’s suggestions for painting the silkspan, I mixed acrylic titanium white and raw umber to give an off-white color, then diluted the paint so that it could be used in an airbrush. I have a couple of cheap single-action airbrushes that gave a nice broad spray for coverage. Cardstock was used to make patterns for the sails based on the drawings of Kathryn’s sails in the HAER documentation. These patterns had the locations of all of the grommets for mounting mast hoops and other rigging details marked where appropriate. Using the outside of the pattern as a guide, the outline of the sail was drawn on the silkspan and the location of all of the grommets and reinforcing pieces was marked OUTSIDE the boundary of the sail. Making the marks outside the boundary enabled me to keep the actual sail clean and free of pencil marks. The sail was cut out leaving enough excess to still show these marks. Reinforcing strips of silkspan were cut for the areas that would have lines attached. These strips were stuck onto the silkspan using acrylic matte medium. The medium was applied to the strips using an artist’s paintbrush and then while the medium was still wet the strip was attached to the sail. More medium was brushed over the strip to ensure a good bond. The matte medium remains flexible after it has dried. After the reinforcing strips had set, a small awl was used to punch holes in the sail’s perimeter as indicated by the pencil marks that had been made previously. The sail was then trimmed just inside the border line to arrive at the final correct size. Because the sails will be furled, I decided to make both the mainsail and the jib somewhat smaller than the full sails. The mainsail is about 2/3 of the height of the full sail, while the foot of the sail remained at the correct length. Also, due to the furling, I didn't try to make any of the seams on the sail. The next step is to install the mast hoops and other connections on the mainsail, which will be the subject of the next post. Thanks everyone!
  12. Part 80 –Rigging Plans Kathryn’s rigging is fairly simple, especially as compared to square-rigged ships. However, there are still opportunities to cause rigging problems by performing some of the work before other components that should be installed first. Avoiding this situation requires a bit of planning to understand the sequence that will work best. The first step was to develop a description of each line, including rope and/or wire required, the termination points of the line, and the route that the line would need to take. This was developed as a Word document. The following is an excerpt from the document, describing the Topping Lift. The next step was to identify each task required to install the particular line or component, as in the following excerpt, and to build these tasks into a spreadsheet. A sequence of tasks was then put together, where the tasks were numbered in the sequence that they should be performed, blending tasks from the various components or lines where it made sense to do so, and then sorting them by the sequence numbers. The following excerpt shows a portion of the resultant plan. I’ve attached the Rigging Details and a sorted Rigging Plan as PDF’s for those who may be interested in seeing these documents in their entirety. I fully expect that some changes will be made as work progresses, but these are good overviews of what needs to be done. KATHRYN Rigging Details.pdf Kathryn Rigging Plan - Sorted.pdf
  13. Hi Kurt - glad you're on board - better late than never! Now, I'm looking forward to your Newsboy build (right?)
  14. Hi Mark. Yes, the main halyard runs to the starboard cleat, and the jib halyard runs to the port cleat.
