I would think that you are ready to do some clamping, but do it with caution. To start you should clamp for a minute then release then clamp another minute. Clamping is something that you have to get use too, nothing you jump right into. What are you using for a clamp? Cable clamp are good to start with, which you can buy in Home Depot or Lowe's.
Jayhawk: It does if you do it wrong. You may want to start with the basic Uli before you jump into clamping. It's essentially the same thing except with your hands.
