Serenity - April 4 2007 |
This is a drawing of the LED configuration I hope to have for the rotating engine. A friends is going to look at making a circuit for me and these are the outer dimensions he needs |
More casting |
I have been having problems with the landing pads as the resin flows like honey and it is not easy getting all the little bubbles out. This produces a higher rejection rat then I would like |
I also look at casting the engine exhausts and I have had problems before with loads of trapped air bubbles. This time I try putting the casting in my vacuum bottle with the hopes that the air wold boil away. No such luck as you can see the multitude of air bubbles. I will have to think about trying to make a pressure chamber. |
