Try it with the 3D printed parts - I expect it would work. Good project.
you could print with polycarbonate filament for a strength boost.
That would mean I'd have to buy some polycarbonate. And then go through the teething pains to learn optimum values for my printer.
What I've found so far is that with the vibration from the impact wrench that the nut holding the cylinder loosens. I've cranked it down tighter but the plastic tends to deform.
For me, so much easier to use some filler primer, wood body filler and paint on the patterns I've already printed and then cast out of aluminium.
And then when I bore the holes I can use the CNC to ensure that they are in the correct spot to keep the rods parallel.
The patterns should be painted tomorrow.
Meanwhile working on some software to count socket revolutions and set timeouts .
