I'm not sure I understood properly but did you say your neck is made of quilted purpleheart or is that just the body wings?
If it is the neck also, I have to warn you that purplheart chips very easily at the corners when you rasp and file it, you have to be very careful when you work around corners. Most importantly, purpleheart is a *bitch* to work with it is very dense, hard wood meaning it will use up your tools faster and it is VERY long to shape things by hand.
have a look at my webpage in my signature, I made a 3 piece maple/purpleheart/maple neck, it looks nice but the purpleheart wasn't that nice to work with. I still have file scatches on the purpleheart bits behind the neck and I KNOW i'm going to have to sand this for quite a while (I got no electric sanders!)
