Preparing The Blanks

Plane the stock board to 5/8" thick or, use specially made PSI Project Wood. Cut 2 blanks to 2-1/2" square. We recom-
mend finished blanks 2-1/4" diameter or smaller. Mark the center of each blank, and drill a 10mm hole through each.
Cut/trim off the corners of the blanks to make it easier to turn on the lathe.
Gluing: Use a liberal amount of 2 part epoxy glue on the brass tubes. Insert a tube into each hole with a twisting motion
to spread the glue evenly inside. Use sandpaper to scrape off excess glue from all surfaces.

For mounting the blanks with a center bushings (left side of Diagram 'B') slide the bushings and the blanks onto the
