sorry for dub post, but now that i just got off my phone and onto my comp so i could see the pics better, i can see that you do have little measurements written on two of the cardboard templates, but i'm still having trouble reading/interpreting them... is the measurement for the side the arrow is pointing at? or for the length of the axis that arrow travels along? also just a rough height/width/length of curve set of measurements for the half-circle piece would be really great too, also thanks for the thread!
