Our delivery of waterjet cut 25mm 5083 aluminium turned up today :) This was cut using a dynamic head system which nearly eliminates the flare angle of the cut often associated with this cutting method.
The finish is really good, although some of the holes are a little baggier than they should be. We were told if anything the holes would be under size, but that isn't the case with all of them. For the next batch we will alter the drawings to reduce the critical holes size so they are definitely cut under size, and finish them ourselves.
The top and bottom aluminium femur parts are a pretty good fit into the main steel femur section.
