Using poseparams in sweps

Can someone teach me how to do it?
I have an poseparameter for a gauss gun (the name of it is gun_spin)

How can i make it work aling with the swep (making it run along with the other anims and specify an frame for it to start and end)

Any help is appreciated!

**[Entity.SetPoseParameter](**. As for getting the names of the pose parameters, you can use Half-Life Model Viewer (HLMV) in the Source SDK.
