The 7/16” tenon and the tapered inside
of the live center. I do not use a center point in my live center except
to hold a pen mandrel end. All other turning I do with the cup as a
contact area only. |
 |
Apply a finish of your choice. I use a
three-part finish made of equal parts of denatured alcohol, boiled
linseed oil and clear shellac. Lacquer and other surface build finishes
look bad on the faces after a few years of use. |

I saw a video by Dennis White of England
turning a gavel and it showed how he drilled the head perfectly centered
in a jam chuck like this one. It looks bad to have the handle angled
to the head or offset to one side when you look at the gavel from the
end. With this method, all you have to do is drill and the handle aligns
perfectly with the head.
Make the jam chuck from softer wood than the
gavel or the head will be marred in this process. |
 |
I drill perpendicular to the grow rings of the wood.
Drilling through the rings instead of with them will help avoid splitting
the head with a tight fitting handle. |
 |
Rotate each end of the head past a fixed point and
adjust the head until both are the same. Tap with your hand or soft
face mallet to adjust. |
 |
Measure the diameter where the head will
be drilled and subtract about ½” so the drill does not
go all the way through the head. If this was a carving mallet or other
type shop mallet I would not mind the handle going all the way through
but for a gavel I think it is not good practice. |
 |
The threaded hand has a short section
of straight shaft about 3/8” long that I counter bore for at
the start of the hole. |
 |
Now transfer the depth measurement to the
drill bit. I use a piece of tape to mark the drill. |
 |
Turn the lathe on and drill to the depth mark. I usually
drill at a speed around 300 rpm. |
 |
The opening for the handle is a convex shape with two
high and two low areas. I chamfer the opening with a gouge to allow
the round shape at the top of the handle to seat all the way down to
the low spots. |

You will find out if you have turned a
gavel head exactly the same measurement on each half if you add an
element like this small bead in the center. You will also find out
if you lathe centers align when you start to drill. |
