The concavity wasn't too bad that we checked this morning but it needs something to be done anyway. We laminated inside deck for reinforcing the chain plates and laminated splashes.
It was so good experience.
We can't see the hollow in this picture but it has actually. The depth of hollow is equal to the sum of force of vacume and topside and the air coming through the hole Ogi drilled on the bulkhead. It is cured as the shape with every force equalised. There is a vertical crack on the foam but the resin smeared into that and fixed itself.
Dryfitting the leg of the splashes, we coved on each corner with a special kind of polyester containing carbon fibre and aluminum powder and laminated with one layer of CBM and two layers of EDB on it. The resin has to be rich when laminating.
It is an activation curve of polyester. Chris drew this and I didn't believe that the temperature goes up to 100 degree but I touched the ice cream contaner today and it really is as hot as 100. Pot means working time that the temperature doesn't go up meaining that the resin doesn't cure. The pot length and the gradient depends on the room temperature and the amount of catalyser.
This is what we used for the coving on the splashes. It is usually used by builders because it isn't quite proper to make a boat. The catalyser of this has to be under 3% and even 2% was quite fast to be gone off as we had about less than 20 minutes of working time. If it goes above 5%, it goes off when mixing.
The color is seemed to be silver because of aluminum powder.
I found a model dory inside of our dory.
Sanding a bit.
We had an experiment to see if this pet squashes when it is all covered or either it is covered like this picture. The result was 'no'.
Hand laminating.
but if there is a hole on the pet, it implodes like that, which is same to our boat imploding this time.
