How do i weight the whole mesh to a single bone? I am currently modeling a ladybug and trying to put an armature in it. The ladybug's legs are segmented and i am planning to set 1 piece of bone to every single segments.

The problem is painting the weight often giving me half weighted result. What i want is a way to select an element of mesh using the L key, and assign that whole selection to a particular bone. Is there a way that is similar to what i was trying to do? Thx
What you can do is:


Select your mesh, then select your armature using Shift+RightClick
Hit Ctrl+P then choose With Empty Groups
Select your mesh enter Edit Mode then select the vertices/faces you want to be part of a particular bone and then select the bone you want them to be part of from the vertex group panel and hit Assign as shown below. 



Then these vertices will be part of this bone.
