:-) Thanks, Ed. And I am under no delusions about my driving ability (at least yet). Im not sure to what extent Ill want to be an active link in the chain which causes my robot to get trashed when I eventually build it!

I just winced cause I could see you were getting hit on what I guess is a weaker point. Corners *bad* (part of my design philosophy). Dont know whether it would have been worse for the weapon to take the blade full on instead, though!
