Trouble bonemerging with items onto model?

[nyan :3]

If anyone noticed or its just me having problem before, I can't seem to merge items like hats onto a TF2 model. I can't drag the body part from model (like bip_head) onto the item and make it lock. I tried to do it separately and when I drag the zero slider the neck/head also moves with the item instead of the item being locked in place and dragged closer.

you have to select the entire hat, not the character head when sliding the zero slider. Not all hats can be used with the zero slider

Not necessarily the entire hat, some hats have a bone that mustn't be zeroed in, like the B.M.O.C. for instance. Basically, any bone that doesn't have a same named bone on the character model, leave it alone. Don't lock it, don't zero it.
