Follow along and I'll show you how I made this inside-outside vase with maple on my lathe.
Step 1: Gather your materials
Step 2: Glue and clamp the blank
It is extremely important to ensure these are glued square. There can be no slipping or sliding. So when you are clamping, place the clamp pads on the separation line squeezing all the blanks centered to one-another. once you have them held in place square, add a couple more clamps to get even pressure across the blank.
Wait about an hour and unclamp the blank. Tear off as much of the paper as you can and scrape any glue off the blank.
