Vaahdoteltiin today rudder epoksivaahdolla. All went once more or less Strömsö style, that is, all impressions correctly without surprises. A couple of months so it was evacuated rudder blade wet uretaanivaahtomuhju off and purified lapapuoliskojen the inner surfaces of the brass after which the blade and the door was left to dry in the inside. Now that the fiber had had time to dry, passailtiin door into place small pieces of veneer and less than the height to fine-tune taped cardboards foam symmetry help. Dirt and dust was removed with acetone and a cloth in order to ensure adhesion of the foam. The floor was protected of course, sheet, foam while expanding, easily find their way to other parts of the rudder. When the mixer had been urged, foam symmetry and anyway all the things on the past certainly ready, poured a bucket of parts and sekoiteltiin carefully. This time was used SICOMIN PB-250 foam mate slower hardener (Teasessa was fast curing agent particle which became a hurry when mixing the start of the 30s began to visit the cramped vessel), eased considerably when the job got more playing time. Bring 250kg / m3 foam is certainly sufficiently robust rudder, probably 170kg / m3 foam would have been enough, but now this is at least the eternal, not just attract lighten the rudder to the extreme, would it take a comfortable margin. Now, had time to mix and three minutes before the bucket started to go low. One of 5kg + 1.55kg foam symmetry package will be plenty of shoulder and comes in the twenties as shown in the pictures, but because those are mass ratios accurately weighed, it is good to mix the whole bins and scrape the soles also, according to the ratio is accurate. Of epoxy are with the mixing ratio much more accurate than the polyester. When the mixed foam was obtained tipped into the blade leviteltiin and pushed foam symmetry to the corner, and then placed in the cover and kiinniteltiin clamps. Hatch was another air intake in order to ensure the fulfillment of the platform up to the top, and because the foam tursui more than just each paragraph so succeeded in doing this. That epoksivaahto stuff is quite comfortable to use, as it expands in a controlled and rapid expansion after the start of peaceful continue for some time to have been met is easy to obtain and on the other hand does not occur when the expansion pressure foam symmetry does not need to be the preservation of the pallet jig shape such as urethane. As a bonus, of course, also be sure to sufficient strength and closed-cell, non-absorbent structure.
Blog follows the progress of technology student sailors electric boat of the project and open-minded introduction of eco-boat technology. foam symmetry The biggest project, Finn Express 83 sailboat mounted foam symmetry electric motor. In addition, the boat is carried out myrkkymaalittomuus and utilization of solar energy. The project was motivated by concern for the Baltic Sea, higher foam symmetry prices of fuels, electric motor less maintenance, cleanliness and silence. foam symmetry Like other club projects, the installation is carried out by volunteers and the costs will be covered by the assistance of donors.
