First clear 2000's Bonneville buttons in the world?
I need to get back to the electronics end of it, but I couldn't resist making some test buttons. Mainly to familiarize myself with the molding and casting process. I'm just using some silicone and resin from the hobby store for the testing. I want some silicone with longer working time and resin with faster demold time.
The first one was the Auto button. Seemed fitting as I destroyed the other one. It turned out flexible though. Not sure if I got the mix wrong or what. The second one was the Fan Up / Down one. That one turned out nice and hard. I didn't really do anything different that I'm aware of. The resin is supposed to be really good at degasing itself, but most likely that is in an open pour. Not so much in a 2 part injection type mold.
I hope to have the ability to actually injection mold projects like this in the future, but resin casting will have to work for now.
That said, the bubbles are unacceptable, even if they will be covered with paint or something. I'm setting up a vacuum chamber and pressure pot. I'm going to have to wait a little bit for the vacuum chamber. I grabbed an overkill vacuum pump, but I need it to get the A/C back together in my truck when I put it together anyway.
The pressure pot is up and running.
I just put the front cover of the headlight switch in the pressure pot @ 40 psi so that will be the next part to come out, hopefully with any bubbles squished down to basically invisible.

Mocked up.

Had to get some ideas flowing on that part of the process. Back to electronics.

Very impressive work on the buttons!

Info on dropping a 92-99: Here.

Almost perfect. Both defects my fault. One of the vents was too small and didn't let the air out towards the bottom.
I overfilled the mold and thought it would be a good idea to put a chunk of clay on top for weight. That made it too thin. I didn't notice it at first, but it broke through.
I should have just let it settle naturally.
I'm thinking try sandblasting the back for diffusion. Have to see how it looks with lights.

Ignore the crappiness of the text. I wanted a preview so I scraped it in by hand with a poker.
5w laser is on the way which I think should be able to etch a layer of paint.

Progress on dialing in the laser settings on some test spoons.
looking very promising.
I was worried about my artwork being a little transformed, but thinking about it I think that is what I want. Taking the picture from the top deforms the artwork, but the laser goes from the top so cutting it deformed should result in the correct layout on the curved surfaces. the High and Low in my artwork are curved a bit, but they look really good on the spoons.
(Sorry about the YT links if you saw them before I deleted them. They weren't supposed to be there. Watch later videos.)

I just wanted to post some pics to show the project hasn't been abandoned.
I will be writting an update when I get a chance. I will also have to start another thread for some HVAC mods I did.
Some progress pics.
