RoyalM - The smallest screw plate I have for my lathe is still larger than these two blocks. So, I need to square up and glue these to two more larger pieces that, in turn, will be screwed to the face plate. These two small blocks are indeed the sacrificial ones - allowing me to cut into them to achieve the right profile on my handle. An alternative would possibly be, to use a four jaw chuck... which I don't have.
When I'm done turning the pieces, I'll just saw off the blocks as close to the handle as possible and grind/sand off the remaining wood. The paper should actually be newspaper....something about the type or orientation of the fibers, or something. In theory, the paper will just tear away from the handle block leaving little clean up.
