Faceplate
turning is one of the two basic functions performed on the
lathe (the other is spindle turning). The finished product
of this lathe function is usually a stand-alone project such
as a bowl or a plate. It can also be a component of a larger
project.
We've
assembled some basic information to help you get started on
this fascinating aspect of woodworking, and feel confident
that with some practice, you'll be creating some handsome
projects.

1. Start
by cutting your stock to round on the bandsaw. If you've glued-up
your stock, be sure to keep it well clamped and allow the
glue to set thoroughly before attempting to turn it.

2. If
you don't own a bandsaw, cut the turning blank into an octagonal
shape on your table saw using the miter gauge with the safety
grip to hold it securely. Safety Note: If you don't own a
bandsaw and are planning to use your Table Saw to round-out
your turning blank, we recommend that octagonals less than
8-in. be cut with a handsaw, since they can't be gripped safetly
for cutting on a Table Saw.

3. Drill
a hole in the center of your stock to the depth of your inside
contour. The depth gauge function of a Dial
Caliper is typically used by experienced turners to measure
theis depth. Mount your stock to the faceplate using #12 x
1-1/4-in. long (minimum) roundhead wood screws. If screw holes
in the back are likely to interfere with your design, you'll
have to attach a "sacrificial" piece of stock to
your faceplate, then glue your actural workpiece to this piece
of stock with a single layer of paper between the two. Allow
to set for at least 24 hours before turning.

4. Adjust
your tool rest so the cutting edge of your chisel is in line
with the centerline of your stock. Wear eye protection...a
Full
Face Shield is considered to be by many to be the best
choice...but See-Through
Shields that can be attached directly to your lathe will
also do the job quite nicely.
If you're
using a Shopsmith MARK V, start by setting the speed at "Slow".
A good set of Bowl-Turning
(Scraping) Chisels will make a big difference in your
results. Start by turning the outside of your bowl to round
using a Gouge or Roundnose Chise ground to an 80-degree bevel.
Re-adjust your speed to "B" or "C" and contour the outside
using a Roundnose Chisel or a Bowl Scraper. Note: Speeds given
are for bowls 6 to 10-in. in diameter. For larger diameters
use slower speeds. (Inset: Chisel and tool rest positioned
for scraping.)

5. Start
contouring the inside of your stock by working from the outside
of the drilled hole toward the center. Continue working from
the outside toward the center of your stock until you achieve
your final shape.

6. Remove
the tool rest and sand your piece. Start with coarse or medium
grit and end with a very fine (220) grit. Be sure to protect
the way tubes and wear a dust mask when sanding.
