Yes, thats standard clamping law - bolts close to part and back end of clamp slightly higher than part;)

They do work well though, todays part was another total success, I don't think the stress on the part is that high in this case, there is only one cut that will put it under strain - the second/last pass on the 5mm roughing tool which separates the parts from the central stub, after that it's just light tickling with the 2mm tool.

The next major issue is getting some sort of chip control round her - the mess is ridiculous.
