Remplacement des hublots sur Auskalo

Replacing Hublots with EPDM gasket.

My F10.90 suffered water leakeage in the hublots. The water entered across the screws. I tried to use a new method for avoid this problem, I hope that it will be a long time solution.
First of all I removed the old hublots with a guitar string. Really I had to use 3, the first was to thin and I broke it very early, the other 2 were the most thick that I could buy in the music shop. I spent 6 hours for remove the 4 hublots.

Then I cleaned the surface of deck were hublots were placed, that was a dirty job made with chisel, spatula and acetone. 3 hours per hublot more or less. Also I sand the surface of hublots.

The black line of the deck was very worn and damage in some places. I sand it and repaint with 3 coats of water based polyurethane paint, the result was good.

When the hublot surface and deck were ready I place a EPDM gasket all around the perimeter. I choose EPDM due to it can resist UV radiation, hot temperatures and salt water. Before to choose EPDM I think in neoprene, rubber, nitrile and some others types of gaskets. EPDM gasket can be found with 1 autoadhesive side (I bought this) or not. I dont remeber exactly the price but I think it was 0,25 € per meter, more or less. I also glued the external part, betwen gasket and hublot with a thick line of MS- Polymer, a dyameter of 0,5 cm. After that Hublots were screwed to deck. Also the hublot´s holes of screws were sealed with polymer.

Inside I used the old wooden pieces for made a new ones. I made them on poplar wood, 0,4 cm. For protect them I varnished them with water based poliurethane varnish. 3 coats on each sides. Also varnished the screws holes.
Above these pieces of wood I will place another pieces, same size of elm wood.
