2006-01-25 A picture may describe what kind of strips I am looking for. Finally I decided to shrink the height from 24 mms to 20 mm.
2006-01-25 Sandwich construction: wood strips between glass cloth packed in epoxy.
2006-04-09 First anniversary is behind. Too much snow and too cold to go further.
2006-04-10 The moulds needed some shaping and still needs after this coarse grinding.
2006-04-11 The result was mainly sawdust on the floor.
2006-04-18 The brackets could have been attached on the other side though it was a minor inconvenience to carve them.
2006-04-29 Local medias are awake... "The World is completed in other means"More...
2006-05-01 I tried to fasten the inner stem before bevelling it, but the result was not satisfactory. It is easier to first saw to the center line and fix the piece in right position afterwards.
2006-05-25 The transom is built from plywood and teak.
2006-05-28 A digital weighing machine for kitchen use is a practilal aid for measuring the ratio of epoxy resin and hardener.
Every one can notice that the picture and this text has nothing to do with each others.
2006-05-28 Messing around with the transom continues...
2006-06-30 The transom is now in the correct position. Finishing has to be done later.
2006-06-30 The inner stem will be fitted here - yes, I am not a carpenter.
2006-06-30 The hog is laminated from two planks.
2006-07-01 The jig is almost finished.
2006-07-02 Beveling the transom was not that hard. The frames should have been some wider but that gap can be filled with epoxy and sawdust.
2006-07-06 An old fashioned screwdriver and 300 screws are waiting for the strips.
2006-07-20 Scots Pine (Pinus sylvestris) strips are waiting to be glued.More...
2006-07-20 700 meters of precision work. Thanks to Mr. Markku Pöppönen.More...
2006-07-23 Something went wrong with the stem. I had to fatten it with thin planks to get some extra 2 centimeters more length?!
2006-07-23 The first strip is laid.
2006-07-23 ...the second strip and I tried to find some use for the clamps.
2006-07-23 The strips had to be fastened temporarily to the moulds. I nailed small pieces of strips which were covered with tape. They worked also as guides when fitting the next strip.
2006-07-23 I decided to use one component PU-glue instead of epoxy.
2006-07-23 The first day is behind.
2006-07-24 The second day and I understood why it is recommended to use gloves while working with the glue.
2006-07-25 The stem was supported to the jig with a piece of plank and wooden plugs. The plugs has to be cut off before the strips will cover them.
2006-07-26 Gluing the strips is quite boring.
2006-07-30 First kilogram of glue was enough for two hundred meters or 21 laps. Bending and twisting the strips is now quite demanding.
2006-07-31 ... and bending. You have to respect that time the glue needs to adhere.
2006-08-02 I wanted to see how the transom will look like.
2006-08-02 Only imagination seems to limit the ways how strips can be wrested and clamped. You have about 60 to 75 minutes time to work with a glued strip...
2006-08-02 which is enough. With a faster glue or epoxy I think that it would be almost impossible to manage the work single-handedly.
2006-08-02 During one holiday You can easily fasten 3+3 strips.
2006-08-03 Things are getting worse.
2006-08-05 If the end would not be outlined this would not be fun anymore.
2006-08-06 The second bottle of glue served for 26 laps. I was lucky cutting the nozzle in a way which did not waste as much glue as with the first bottle.
2006-08-08 The good quality of strips can be seen on this picture. Notice also the glue which is not foaming as typical PU-based glues do.
2006-08-08 I had to test my new random orbital sander and used sandpaper with grit size of P80.
2006-08-10 There is not much use for clamps anymore. The gap between strips does not look very nice, but it will anyway be covered.
2006-08-12 Looks like a boat.
2006-08-12 Bending the strips is not very easy. One pair of hands is almost not enough.
2006-08-12 Gaps and screw holes are filled with epoxy resin mixed with dust from the sanding.
2006-08-12 Before coating with epoxy resin I remembered to take away those horizontal mould supports which later supported the first strips.
2006-08-12 Not much attention was paid on finishing the strip ends because the gaps will anyway be filled and covered with epoxy.
2006-08-13 Stuffed with epoxy mixed with dust and unfinished.
2006-08-20 64 pairs of strips fastened with 2,5 kilogram of glue, sanded and worst dents filled with epoxy, washed with acetone and coated with a thin layer of epoxy. In all 2 kilograms of epoxy is used so far.
2006-08-26 The hull is now sanded. A "tent" is raised to keep the flying birch seeds away and to keep the heat from a kerosene heater over the night.
2006-08-26 The fiberglass cloth weights 300 grams / square meter...
2006-08-26 and it is 125 cm wide covering one side. I fastened it temporarily with masking tape, but perhaps it had been better to use a stapler.
2006-08-26 In the "lab" there is a digital weighing machine, a yogourt can and a putty knife. At the eye level there is a list with different amounts of resin and hardener. I used to mix only about 150 grams at time. The fiberglass was rubbed with that plastic spreader laying on the table. The metallic one get stuck with the fibres.
2006-08-26 Worked for one hour with the first side. The other one was more complex when I had to get rid of the tapes and some wrinkling glassfiber.
2006-08-26 Two layers of resin on both sides. I mixed only about 150 - 200 grams of epoxy at each time. There fore there was no hurry at any point.
2006-08-26 The third layer was mixed with pigment. I thaught it would be easier to adjust the thicknes of the resin.
The evening gets darker and without a lamp I could not manage to read the weighing machine to get proper mixing ratios.
There is also a paraffin heater in the tent giving warmth to secure the curing process.
2006-08-27 Surprisingly the shed had not burnt down during the night. The hull is covered with approximately 5 kilos of epoxy ie. half a kilo per square meter.
2006-08-27 The boat will hopefully be turned around for the first time in spring 2007. On the inner side we can see where all that glue disappeared while I worked with the strips.
2006-09-14 This boat needs a keel and after all thinking I decided to construct it by laminating simple planks to a solid piece of wood..
2006-09-15 Building the skeg started with finding the right position for a planed plank.
2006-09-16 Marking two lines...
2006-09-16 and roughing the epoxy.
2006-09-16 The plank is also roughened, moistened with epoxy and screwed into the hull. Wooden wedges underneath keeps the plank stable. The gap is filled with epoxy mixed with microfibers.
2006-09-16 -- to be continued --
2006-10-16 The engine has to be picked in pieces for overhaul. At least some gaskets needs to be renewed.
