Take your last TAPERED cut on the butt & while it's still in the lathe, cut the wrap groove, to a depth of .020. Taking the butt out of the lathe & reinserting it at a later time, can be pretty hard to do & still have it turn perfectly true. This way when you sand you will be sanding the cue & the wrap groove. When you spray you will be spraying the same amount on the cue, as well as the wrap area. At each step you can lay a piece of linen in the wrap area & check it. The linen should be just a hair higher than the butt. That way, when you press the wrap it will be flush...JER
