Clint please dig your vehicle project out of the closet and get us some WIP pics. I would love to see what you will be working with. As far as a date for final cut off January would be great if it will get more participation. I hope to see some pics from others soon!
Doc I know you want to use these things to get air bubbles out of your molds.
They are test tubes that held Hulk bubble bath and came like a lab set. They were a gift to my youngest son a year ago and you know I don't throw anything away. I can tell you they are slightly bigger than a cigar tube that I have that I almost used, so that might be an idea for you.
As far as my vehicle design, I didn't start with a plan. I went in my attic, got out my vehicle fodder/random yard sale junk box. The Trax, ST ship and disk holder among other thing that didn't work were all I had to work with. I just put different things together until something looked cool. I had the shuttle sitting on the trax and looked over at the disk holder and a light bulb lit up over my head.
