Can someone please tell me if it is a mission to upgrade a t-rex 450 with a cnc head.I am going to buy the complete cnc head and try to fit it.Is there any modifications to make?[>:]

As long as you get the right one, it should just be a bolt on and set up deal.

It gets easier each time you do it. I sit at the coffee table in fron of the T.V. when I do my repairs. For me the biggest mission is changing motors. Getting those mounting bolts to not fall out the frame and to go in straight down so as to lign up with the motor gives me greay hairs every time. Everything else has become a breeze.

Which T-Rex do you have?
