Well I'm not too worried about flex really, I'm actually kinda hoping it flexes a little bit. Flex acts as a bit of a cushion on other parts in my mind, and my new setup for this probably won't allow bending/breaking things flex, but it'll allow for a little wiggle room so to speak. I'm just trying to keep things as simple as possible for now. Simple = less parts = less money and it's nice to have it all simple to work on and such. I'll be done with the main design in about an hour and I'll post it up so you can see my approach on things. After that it's just a bit of refining and I should be able to send it off to the machinist tonight/tomorrow.
