Re: 4 inch Wheel of Doom
Adam, I understand where you're coming from. First of all the wheel was designed around 6063, because that is what we had laying around. The safety factor was about 16 with all the proper forces included (an engineer helped with all that). Then a random sponsor donated some really cool material, 7068. So we decided to make it out of that, we were going to take out more material. But a couple of fellow members from other teams asked the question "Why not plastic?" So we as a team figured that plastic would be a lot lighter but none of us really have ever worked with plastics. Also when using plastic, you need to add material. Adding or subtracting material is not the issue here. I have looked up some specs on plastic but wanted some people or teams opinion on what type of plastic they used and how it worked out for them.
Thanks Adam for the concern
