Having made some improvements to my lathe it was time
for another small project to try it out. This time I made a small spinning top.
The blank consisted of a 20 mm thick piece of maple with two pieces of mahogany glued
to the side to get sufficient thickness for the wide part of the top. I cut off as much
as I could on the bandsaw before putting it on the lathe.
The blank mounted on the lathe. I'm adding a drop of oil where the workpiece
spins on the cone of the tailstock.
Starting to rough it out.
Before I made a motor mount, I clamped both the motor and the lathe to the workbench
to maintain belt tension. With the motor attached to the lathe, I could
use it without clamping it down. But with the lathe as light as it is, and the
vibrations from turning, the lathe started to wander away from me. So I clamped it
down again.
Turning the blank down sufficiently that it no longer has any flat spots.
After that I shaped the main bulb. With the bulb shaped, I started
thinning down the stem and the point of the top. I thinned these down last
because once they are thin, the workpiece becomes too weak to do
much work on the wide bulb part of the top.
Now sanding it smooth.
The last thing I did was to turn the point of it down to about 2 millimeters
thick -- thin enough for it to almost break. I half expected the
workpiece to go flying in the process of doing this.
I then took the piece out of the lathe and cut it off on both ends.
I wrapped some paper around the stem, put it in a drill, and then spun it
against my strip sander to finish
shaping the point.
Testing it. Getting a one minute spin out of it was relatively easy.
Good enough for me.
There are brass tops that you can buy that can spin for ten minutes
straight. I wasn't aiming for that kind of record.
