Based on a point load I get 0.07mm deflection with the two 20mm unsupported rails and the 150mm bearing spacing in the drawing. I'm not sure how to calculate the torsional deflection...this is getting a bit beyond what I've just done at school and I'm too tired to start reading up now so I'll leave it for tomorrow!
