I am currently researching moving hoods and was greatly inspired by 254 and their geared hood in 2016. However, I can’t tell what they used to slide with, were they bolts or tabs that rode in a groove or something else?
I can’t tell exactly, but it looks like hey have a slot in the moving part that some pins ride in.
In this post it looks like a servo motor but hard to tell.
I have a design for a similar mechanism that uses a coaxial pivot around the same axle as the flywheel, and uses a neo 550 to adjust the hood. It isn’t quite as advanced as what 254 did (I am pretty sure they used some type of curved bushing to slide) but it should have about the same functionality.
My design doesn’t really need much machining, but it would be significantly easier to produce with a cnc router. It isn’t a fully complete model, but it hopefully gets the idea across.
(Disclaimer, my team hasn’t yet built this exact design. I worked on something similar in 2013, but it isn’t exactly the same)
Also, it would work fine with only a single neo 550 for the articulating hood, but 2 helps to make it a bit faster.
