I'm gonna try a different way to make a plaster mold.
Instead of using the cottle boards, I decided to use regular wooden boards.
I bought a longgggg wooden board and cut them into different sizes.
Then I sanded all the edges to smooth them down.
Like this lol.
After sanding them, I sprayed the waterproof coating on both sides. I did it in the house and I got yelled at by family so much that night lol. And because I didn't wear any mask, I felt some toxic stuff in my lungs. The next day, I had a huge headache and felt like vomiting.
Yes, I learned my lesson. Do not spray anything indoor without wearing a mask lol.
I used rubber bands and a strap to secure the board and it works great!
Here's the link to the place where I bought the strap: https://amzn.to/2EfaLN0
This works great for holding mold pieces.
This is so neat!
It's time to pour some plaster!
Here's how to calculate the amount of water and plaster you need:
length x width x height (inches) x 0.025 = Amount of water you need (pound)
Water(pound) x 1.5 = Amount of plaster you need (Pound)
And it's also very important to wait until it becomes heavy cream consistency.
I'm not patient enough and I always pour it even when it's still watery.
And then I see disaster and regret every time I do this.
Make sure to coat the board with a waterproof spray.
I did it without spraying them once and they warped :(.
One side came out very very nice!
It's so beautiful.
Then I drilled holes for the keys.
And gave the Kaonashi face for the other side of the mold.
I didn't wait till the plaster becomes cream consistency,,, again..!
I had some leak problem but it's okay.
I carved out one part for the pouring.
I realized I need this because I make a big mess when I pour out slips from the mold.
Idk why the color is different.
But still works perfectly!
I can't wait to use this mold!
I'm gonna be mass-producing Kaonashi hideout!
