As promised, here are a few CAD drawings of two different ways that sliding trigger blocks could have been done. The first narrower one would work with the 1/4 F aperture described by Vitruvius. The wider one that clamps completely around the top of the canalis fundus is better with the wider aperture on the later Cremona battle plate. There is an intermediate narrow version where the trigger block clamps into grooves cut into the sides of the rail. I haven't finished a drawing of that one yet, But I'll get around it to eventually. I'm still waiting to hear from anyone who has found evidence that the "sliders" on there engines actually slid. Any takers?
