  1. Launch day at the Yarra river. We call her phosphorescence. Found a canoe launching jetty on the river with the carpark only 60m away. I was first out as I figured if it is going to sink then it should be the captain who goes down with the ship. Well it didn't leak a drop nor did anyone capsize. The canoe is an absolute delight to use. Light, fast and stable and turns OK. I can see it part of the family fleet going on camping trips. Four of us had a go from 50kgs to 100kgs (I was worried about my seat but it didn't break with 100kgs) The seat is very comfortable though I will have to
  2. well the stonefly is finished. I will add the remaining construction photos here then post in the launch section. The final job to do was to coat the fabric using oil based exterior grade clear polyurethane. I put on 4 coats which is slightly yellow/green but overall not a bad look. I was a bit disappointed to notice s few wrinkles in the side after a few days. Nothing really bad but they show up and would look better without them. I did try a little heating with the heat gun from the inside, but I was so paranoid of melting that I don't think I heated it enough to do anything. It
  3. Looks awesome John. I can see in your workmanship that you have built this way before. The firefly is a great looking craft and I like your colour scheme. How is the fabric the same colour on the inside? Does it soak through or did you paint the inside? Hope it paddles as well as it looks. cheers Tony
  4. Thanks for your insights Omar. Sorry I just saw your reply now and I have almost finished my build. I did use 5/8'' x 1'' and 5/8'' x 5/8'' for the stringers and 5/8'' x 1 1/2'' for the gunwales though I did up the plywood thickness for the frames from 1/2'' to 5/8'' which probably only added a half pound or so. I haven't weighed it yet but it is definitely lighter than my fibreglass canoe.I had my frames cut on a computer controlled router which did a great job. I did the offsets on my autocad then sent off the files to the CNC people. I have many years of fine wood working under
  5. Thanks Dave, Good advice re epoxy. My stonefly is nearly finished now. I have successfully skun it and have given it 3 coats of finish with 1 to go. The fabric went on really well with no dramas. Got myself some amusingly home made looking canvas pliers from chine an ebay which despite the crude construction of said tool did the job and allowed me to pull it up nice and tight. I had a few minor wrinkles along the gunwales which the iron managed to remove though I missed a couple on the underside where the fabric had been folded for postage. Maybe next time I will iron th
  6. Really starting to look like a boat now. I decided to use more cedar for the decks as I didn't want too many different timber species competing for attention. I had some short bits lying around so ripped them to 12 mm thick with a slight taper on the edge then glued them together to get a slightly curved top to the decks. I made a couple of templates and settled on the size. As I mentioned in the previous post in retrospect I should have moved the rear handle forward a bit further and inserted the ends into the inwale instead of gluing it to the ends of them. This limited me to a shorter rear
  7. Work has continued on the stonefly with good progress. Trimmed the cedar outwale to bow and stern and glued it to the frames and ends with epoxy being careful to apply just the right amount to minimise the clean up. Clamped it on then did the other one. Next I made the blocks out of marine ply and worked out how many and where I wanted them. I chose plywood as I think the stripey look matches the ends of the frames and I wanted minimal timber in between the gunwales. It was at this stage that I decided to add some handles to each end which Henry turned from some cedar. These determined how we
  8. thanks Jeff. I will keep it pretty low and see how it goes. I have it notched over the second stringer - the square section one and up against the frames. cheers Tony
  9. Hi folks, Has anyone any tips on installing a seat in stonefly? I would like to know the ideal position from ends and ideal height - the drop from inwale. Paddlers will be mainly Henry aged 14 and about 52 kgs (110lbs) but sometimes me about 70 kgs about 150lbs). Thanks Tony
  10. Starting to get very exciting as we added the top stringers and held them in place with the ocky straps. Next we clamped the bow and stern in place and quickly trimmed of any excess length before starting to trim the stringers to the stern. With my japanese saw and block plane we had them nicely fitted in no time. It was then we got out our new roll of sinew, drilled some holes and paying careful attention to the book made our first lashing. Pretty good though they all shifted down a few mm's on tighten them up. At the bow I had a hole above and below the stringer through the frame. That stopp
  11. The strongback. I bought 2 x 3.6m lengths of 90mm x 45mm framing timber for my strong back and screwed it to a few other bits of 90 x 45 to extend the length, carefully leveled and straightened it then added a few strips of MDF to give me a nice flat surface to build on . This was then screwed to some blocks on my little saw horses so it was at a good height. Before I did anything else I gave all the long lengths a sand as they were too long for my workbench. I then carefully marked out the frame positions made up some brackets and screwed them in place. Now I feels like something is happening
  12. I next sourced and bought some western red cedar for the stringers. I bought 10mm x 50mm 2 x 2.4m lengths and 2 x 3.0m lengths. I then ripped it up on my table saw to the exact dimension of the stringers and gunwales and scarfed them together using my trusty epoxy glue. The scarf joints are about 300mm long. Next I ran it all through my router table with a 2mm radius round over bit. So far so good. I used masking tape to clamp it together whilst the glue sets. Brilliant stuff.
  13. Hi fellow boaties, I have been building a stonefly with my 13 year old son Henry. I decided we needed another canoe as Henry grew and no longer was comfortable sitting between myself and my wife Polly in our touring canoe. I bought the Kudzu craft book online as I was intrigued by the SOF style and felt it would be a light weight solution to a second canoe as our fibre glass touring canoe is pretty heavy. I started by plotting the frames on autocad using the offsets in Jeffs book. I then had them cut out of 15mm marine plywood on a CNC router which did a great job much faster
  14. Hi Jeff, I had my frames cut by CNC router. He used a 4mm bit so the internal corners are all 2mm radius - perfect. I can't fault it and no burnt edges. It cost me Aus $70 (this includes setup) but would be cheaper if done in bulk. So I would look around for someone who does that in your area. Cheers Tony
