  1. Tom, The nights have been so cold i have had to curtail any large scale epoxy work so i have moved on to the center board and rudder. Based on your experiance, would you weight the center board? how much would you think is needed? Herb [/img]
  2. Lapstitching a lapwing. The procedure is a litlle different from a normal stitch and glue because the boat is built inverted so the stitching is blind but the following procedure works pretty good. 1. fit the new strake to the existing one and clamp at the bulkheads and stem 2. drill sets of holes for 18 guage wire. one hole in the existing strake at the edge of the new one and one hole about 3/8 inch below thru both strakes. space the sets about 10 inches apart - a little closer near the stem. 2a remove the new strake. 3. thread 10 inch lengths of wire up thru the existing strake and flatten against the hull, ends pointing at the keel. 4. brush on thickened epoxy on the lap area of the existing strake 5. thread the lower wires thru the holes in the new strake starting at the stern. the strake will self align as you advance toward the stem. 6. after all the wires are threaded twist them snug but dont over tighten so the boards remain fair. 7. after the epoxy sets remove the wires with a little heat and pliars. No hand made clamps or wedges required and no screws needed to bring the boards together where clamps wont work. [/img]
  3. Keel batten and stem are on. [/img]
  4. Ken I think if I thought I was going to build a bunch of lapwings the shop bot would be a good way to go but for a one time shot maybe not. Tomorrow I put the inner keel and stem on and after taping the joints and fairing off we will be ready for the strakes. Dean wanted to take it for a sail yesterday but I thought it might be a little tender. Thanks for the input. Herb
  5. Progress to date. Starting to look like a boat. [/img]
  6. Thanks for the tip Paul. I will look for it Herb
  7. Well I am ready to set the parts up on the horses tomorrow. weather is so cold its getting hard to keep heat in my shop. probably be about 1-2 weeks before getting around to the strakes. will probably make full size patterns for the strakes from cheap luan before cutting okoume. A little extra work but probably worth the effort and might save time and money in the long run. I would assume that shop bot would need all of the lofting info for the boat? Herb
  8. Well dont feel too bad Doc, all boats are semi submersible. Got the idea for stitching the strakes from building two CLC skerry's from plans. They worked out well but they did provide measurements for all of the strakes. Herb
  9. Getting to the point where I need to scarf some ply together. Attached ( I hope) are some shots of a scarfing jig I have used for years and it gives a perfect scarf every time. The one shown will scarf ply up to 9mm. for thicker ply you can increase the angle a bit. Make the jig with 3/4 stock and attach at a 9 degree angle then attach to the base of your circ saw as shown. wire back the guard the ply must be on a flat surface with about 4 -5 inches protruding so the blade will just clear the table. clamp a straight edge on the ply aprox 3
  10. Not yet, just started thinking about it. Herb
  11. Lapwing hull #7 is now under way. Got the stem assembled, the bulkheads cut out and am in the process of making up the transom. Has anyone considered stitching on the strakes -as in stitch and glue - instead of clamping? Tom, the folks at World Panel Products - Al Jernigan and crew were great, I recommend them to anyone looking for high quality marine grade products. Herb
  12. Thanks Tom I will mention your name. I have dealt with them before when i bought some okoume and a little mahogany for a couple of clc skerrys that I built about two years ago. they are good folks. Herb
  13. oops I did include $200 to $300 in that $2500 for masts. also plans($99) and $100 for misc shipping. I can get the okoume within a couple of hour drive at world panel products in NC.
  14. John and Tom Thanks for responding. I am comming up with aprox. $2500 for materials with 13 sheets of 6mm okoume marine ply but not including shop disposables, masts, sails and rigging. Does that sound like it is in the ball park? Herb
  15. John Thanks for the fast response and it should be enough for me to make a ball park estimate. Herb
