I spent the summer trying to make vintage style tele necks. I used double sided tape on a piece of pine slightly larger than my neck. That is what got leveled with a 1/2" straight bit. The maple got mounted to the leveled pine. After 4-5 test necks out of maple, I’m getting closer, but the necks aren’t there yet to the accuracy I want. I ordered some more upgrades but have to wait for warmer weather. If you don’t have the Y axis stiffeners, they may help you.
