Not because the shapes were incorrect but it comes down to the same problem of measurments not being precise, which then has an impact on other parts of the mechanism. I think I got 2 movements working but it looks messy. Better to do the job properly then leave it messy and prone to breaking.
Because of this, I won't be able to finish the model before Christmas.
I could always save it for next Christmas, or maybe as an early new year model.
