Agreed pappabear. I mentioned this in post #46 of this thread. I got round the problem by adding a slot to the crosspiece! And, talking of long projects, it took me ages to complete my Lady. It drove me mad with all the 10 and 12 BA nuts and tiny flangesLady Stephanie problem with understanding the geometry of this model. The attached images of what I have done so far on my SolidWorks version of Lady Stephanie. If you look closely you can see the hole in end of the beam changes in relationship to the slot in the drop link. This would put side load on the piston rod.
With regard to progress on the model itself, pretty much all I have done is square up castings.
