Notes
from the Shopsmith Woodworking Academy
Spindle Turning
on the Shopsmith MARK V
Shopsmith’s National
Woodworking Academy attendees gain knowledge and confidence
through actual hands-on training and spindle turning is one of the most popular
topics taught in the Academy.
To turn spindles on the MARK V, you’ll need the Tool Rest, Tailstock,
Drive Center, Cup Center and the appropriate Chisels. Remember….make
SAFETY your number one priority whenever you operate the Lathe.
To begin…scraping
and shearing are the two lathe-turning techniques:
With Scraping (A), the cutting edge of the chisel is positioned near the centerline
of the turning and used to scrape away the stock.
With Shearing (B), the
cutting edge of the chisel is positioned at the top of the turning and used
to cut or pare away the stock. See your Power Tool Woodworking textbook for
more information.
1: Find
the center of your squared stock by drawing two diagonal lines on each end
of your stock, from corner-to-corner. If you’re turning hardwoods, drill
1/8” diameter x 1/2” deep holes and saw 1/8” deep diagonal
kerfs to help seat the Cup and Drive Centers more firmly.
2: With
a rawhide (link to 730271 in on-line Shopsmith catalog)or nylon mallet, seat
the Drive Center in one end of your stock and the Cup Center in the other.
WARNING: The spurs of the Drive Center and cup of the Cup Center must bite
into the stock an absolute minimum of 1/16” to mount stock securely
and safely on the Lathe.
3: Position
the MARK V Headstock appropriately. Mont the Drive Center and the Cup Center.
Lock the Headstock approximately 2” from the point of the Drive Center
to the end of the spindle you’re planning to turn. Extend the Quill
to engage the Centers and secure the Lock. Position your Tool Rest 1/8”
away from your stock and 1/8” above the centerline.
4: Use your
Gouge (link to 515027 in on-line Shopsmith catalog) to bring your stock to
round (Shearing shown above). Set your Gouge on the Tool Rest and feed it
slowly into the stock until it just begins to cut. Then draw it slowly and
steadily across the Tool Rest. Turn the MARK V off to check for round.
5: With
a pencil, mark lines on your revolving stock to indicate where beads, coves
and other parts of your design are to begin and end. Use your Parting Tool
(link to 515030 in on-line Shopsmith catalog) to cut grooves in your stock
to the final depths of your turning’s various features.
6: Begin
shaping your stock by cutting the beads with the Skew (link to 515026 in on-line
Shopsmith catalog). Feed the edge of the Skew slowly into the stock. Then
move the handle of the Skew from side-to-side, as needed to shape your bead.
7: Cut the
coves. Select a Gouge or Roundnose (link to 515029 in on-line Shopsmith catalog)
Chisel and slowly feed it into the workpiece, gradually removing the stock.
Move the chisel from side-to-side to shape the cove.
8: Sand
the turning on the Lathe. Fold your sandpaper over several times to help dissipate
the heat that will be generated and protect your fingers. Start with a medium
grit paper and hold it lightly against the rotating stock. Work your way through
successively finer grits for the best results, ending with 320-grit. Flip
your stock end-for-end to sand in both directions.
9: Use your Parting Tool
once again to partially separate your turning from the waste. Remove the turning
and cut apart with a hand saw.
WARNING: Do NOT part the stock completely or turn your spindle to such a small
diameter that it snaps off.
