New swing arm models

[HwitVlf]

There were a couple problems:
You're using an old version of x2mdl for the arm, which has the 'reversed bone #' bug. ‎  That bug makes the weapon attach to the 'shoulder' bone. Get the newer release at the top post here.

Second, the pick just needs to lay on its side instead of standing up (see attached mdo).

I changed those two things and the #4 swing worked like a charm!
