The Beall wood threading kit. Three sizes
of taps and inserts for the router fixture (1/2”, ¾” and
1”), a double ended cutting bit and a pilot bushing to align
the fixture on the router. |
 |
The taps have a long pilot section on the
end that I have cut off to be able to thread deeper in a blind hole.
The largest tap still has the long pilot end. |
 |
Tapping the threads in the head. |

The finished threaded hole with the counter
bore and chamfer. |

I use my Nova chuck with the number 1 jaws
to grip the square for the handle. Center the tailstock end of the
blank and tighten the jaws.
The Stronghold and the small Nova are the
only two scroll chucks I have. It would be convenient to have a chuck
for every different size jaw needed, unscrew one chuck and screw
another on.
If any tool supplies are reading, I would be glad to test
new tools
and write a section on their use. Just contact me and I will give
my shipping address. |
 |
Start roughing to round at the tailstock
end and work back toward the headstock. |
 |
I have the end for threading on the tailstock side.
I mark off the thread length plus about a ½” extra to
turn down for the ¾” threads. With the lathe, running
you can see the blur of the small pencil mark made and finish the mark
around the spindle. |
 |
Set the calipers and make a few sizing cuts as reference
to turn down to.
Remove the excess wood to slightly over the desired
diameter. I set my calipers to about 1/32’” over the ¾” diameter. |
 |
I use a sizing tool to complete the sizing.
The sizing tool works well for any operation that requires an exact
sized tenon, especially when you are working on a project that has
many spindles like a crib or stairway. |
 |
Chamfer the end of the spindle to make
starting the thread cutting easier. |
