Thanks for the answers! Love the picture of the prototype shooter and can't wait to see this thing finished! I have access to a laser cutter at the college I'm going to, so your work with it is very relevant to stuff that I could make in college.
You may want to add an extra set of mounting holes for the linear actuator (not 100% sure on that) but I'm sure testing will clear up any issues. Worst case you can always stick a DART in anyway.
