Conchita, I was not being idle today. There was a new insight,
too.
First, take a look at my spools. These at the request of A's.
It has been a pain in the neck, easy to make, but I had
been reluctant.
The main reason was controlling the depth of the holes
I would need to make, for that matter, the diameter as well.
Diameter thing was OK, I had bought 8 mm pieces. Often, you
do not go XXX mm to XXX mm. I chose a 7 mm dril bit. It is
all empirical, but that does it, as a rule of thumb.
More of a problem was depth control, and in this I was greatly
assisted by the depth lock mechanism with my new
milling machine, seen below.
It is infinitely better than the arrangement I had
with my old machine.
Here above, can you see a small round metal piece?,
roughly in the middle of this image. It is a hexagonal
bolt, which fixes another metal piece behind it.
With this image, it is looking black and square.
It is this piece that stops the whole assembly
(on the right) going down further than its position.
You do not need to refer to the scale at all. You decide
on the depth you want and fix the stopper position
(or height) and that is all you need!
Here above, see some more deep cavity spoons?
I concaved them today. Here for now, I will
talk about convex surfaces, how to sand them.
Here above, this is a disk sander, a very versatile
tool for sanding down the outer bottom of Chinese
spoons.
One problem here is that it is so abrasive (grain
rating at 60) that scurrs are left over the convex
surfaces. You want to remove them, naturally.
How would I do that? Up until now, I have been
using a belt sander, shown below. This is abrasive enough,
too.
However, the problem is that you cannot see the side
that is hidden from you while the convex surface is
in contact with the sanding belt.
That often leads to unfortunate over-sanding and it
can ruin te piece.
Today, instead, I decided to use what is seen below.
In many ways, it is a mini belt sander and it does wonder!
You have every bit of your convex surfce in your
field of view! Abrasive enough, too. I just wonder
why on earth I did not think of this approach before!
I am a happy man now... My wife and daughter will be
back from Sicilly after two weeks there. I may skip
my logging for that reason tommorrow. I do not
know yet...
