Headstock alignment

This afternoon I checked the headstock alignment on my lathe, the headstock rests in the bed's rear V way and is not adjustable so I was expecting it to be correct. Well it wasn't and was out quite a bit, so after creating some adjustment in the headstock V way, I trued up the headstock and now it's spot on - front to back at least. Tomorrow I'll check the up and down alignment, but I'm not expecting a lot of joy there. I was just wondering though, has anyone else had this problem, seems silly...
