  1. Dave I think your plywood clamps with wide shims probably spread the load a little better than my screws and pads. I've changed my method a little, so the screws are now inserted into the edge of the new plank. I think having them bridged put too much pressure on the outside of the plank, past where it was supported by the bevelled edge, causing slight dimples which needed fixing. If you're getting withdrawal symptoms from see a new build - fell free to pop over and give me a hand...! Sorry about the pic - for some reason they keep getting rotated as I load them.
  2. Good things take time...! Nice looking boat you have made for yourself.
  3. ...to get nice 'clean' gains, I made a simple jig for my router to sit in. Works pretty well... I found a site 'Off Centre Harbor' which has many helpful videos. But a series I found really useful was on using Epoxy. lots of really useful tips from a master of the art.
  4. Good to see the planks fall pretty cleanly on the longitudinal bulkheads.... ...then on to the dark art of spiling. Took me a while to understand that you need to have the planks fall in the correct lie without too much tension anywhere. Any tension will see humps and hollows in the line of the lap... yes you can send and fill them to bring them back into line, but better to get the fit right in the first place. I found a photo of Blue Peter Lapwing build - seems there website has gone, but the spiling truss shown in one very low res pic set me off on the right path....
  5. I found the plywood blocks very useful for holding planks together - but don't tighten them with an electric screwdriver! Any mistakes here will show...
  6. Thanks for the advice Dave - much appreciated. I thought it useful to check the stem was plumb - since the saw horses were level, and the Longitudinal bulkheads were identical, likely the transom was level, so I set up a string line from the centre of the transom to the stem. A little parallax error in the photo, but it was on the string. Time for some planks...
  7. Dry fitting the frames and the longitudinal bulkheads showed the advantage in having the two sawhorses level, it all seemed to go together quite well. I figured that if I cut the frames out carefully, made sure the longitudinal bulkheads were close to identical, and made the aft frames square on their marks, that by the time I got up to the front bulkhead, the angle between that and the two longitudinal bulkheads would be pretty close to the same on both sides. 0.2 degrees difference seemed close enough that you'd never see it looking at the boat. I found there is a surprising am
  8. Next I started cutting out frames and longitudinal bulkheads, making the transom etc. It was about here that I missed the text which noted to bevel the aft edge of the transom seat shelf. When first dry fitting the transom to the Longitudinal bulkheads, the mistake was immediately obvious. You learn from your mistakes right? Well at least, we try not to make the same mistake a second time. So i cat the seat shelf off without too much trouble, cut a new one and tried it in place. I forgot to take a photo of it before I started to assemble the frames, but it's a good fit now.
  9. Next the rudder and the rudder stock. I had plenty of ply so I used that for both parts; not so pretty, but it will all be painted so it won't be seen. I covered the blade in layered glass then graphite top coats - a bit of sanding to remove the layers, but getting there... Thanks for the tip Dave - in the photo of the centreboard - it's difficult to see but there are two layers of 6oz glass covering it. The lake here is deep so I didn't bother with an epoxy soaked rope at the leading edge. I may live to regret that should I sail elsewhere!
  10. Well After quite some time without anywhere to build, we have moved into our new house overlooking Lake Karapiro in New Zealand. It's a man made lake used for hydro power generation , there's just a bit of the power company's domain between its and the water. I see the lake from the window in the garage at the back of the house where I will start. Having looked at the plans for some time, I find it's like a map of a foreign city; until you get there, none of it makes any sense. Regretfully, this, combined with a short attention span and an unwillingness to read carefully, inevitably rework is
  11. Just looking at this, is it possible the picture has been mirror-imaged? It appears the control lines from the main come down the port side, but in other pictures, they come down the stbd side decks? Amazing to see how fast your helper is growing! Can't wait to take my grandkids sailing too...
  12. Ah - a picture is a thousand words! Many thanks for your help guys...
  13. Thanks Paul - sound advice. If I can make a boat anything faintly resembling Dave's - I'll be delighted. I guess i'm going to have to be patient - no short cuts!
  14. Dave you note 'hot coating' the hull in epoxy - not clear form the photos, but were you using cloth as well or just resin? I love your work.
