Diagram A / Parts List
NOTE:
A selection of exotic project woods, especially planed to the exact thickness of 5/8'' x 1/2'' wide x 10'' long is available (see PSI catalog).
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.
Turning The Blanks
You may use either of the mounting methods illustrated in Diagram 'B'. You may also turn 2 kits at once by using an
extra set of bushings. Use either 10mm bushing sets listed above (under “Required Accessories”).
For mounting the blanks with a center bushings (left side of Diagram 'B') slide the bushings and the blanks onto the
mandrel. Be sure the inside surfaces are facing each other.
