Ok,
I do have a full professional (can never get the spelling right!) workshop, but if its too hard to mill or drill, its too hard!

If you can ensure any samples supplied for testing are the same approx size (what size are we talking by the way?) I can uniformly armour the middleweight, and might as well put it through a full weekend of fighting/hammering. Might have to give it to someone else to drive on Saturday though as Im working. Friday Saturday night, and Sunday is fine for me so organize it how you want Ill fit in with you, just give me a week with the material ready to weld on to be sure it doesnt come off the robot. Ill cut it back off after if you want it back.
